In circuit decoration, strong electricity and weak electricity must be separated according to regulations. What are weak electricity wires? How to distinguish them during decoration? Let's follow the Handan Decoration Network to learn about what weak electricity wires are in home decoration and why strong electricity and weak electricity are To be separated.
Why do we need to separate strong and weak electricity in home decoration?
According to relevant regulations: wires of different voltages or different watt-hour meters must not be worn in the same pipe.
Strong and weak currents are laid in a steel wire tube to avoid strong current interference with weak currents.SYWV Strong and weak current wires must be separated. This is regulated and cannot be run in the same wire tube.
What are the weak wires for home decoration?
1. Telephone line
In an era when mobile phones were not widely circulated, the telephone was a communication tool commonly used by people for long-distance communication. To ensure that your home phone can make normal calls,AVVR cable you must install a phone line at home. The telephone line is a type of weak wire. Telephone lines are generally made of copper core wires. The number of copper cores represents the number of telephone extensions that can be connected. The commonly used core numbers are two-core and four-core. The number of telephone lines commonly used in ordinary households is two cores, and a few households use four-core telephone lines.
2.TV cable
TV cables are lines used to transmit TV signals and are also weak wires. TV cables can be divided into cable TV coaxial cables and digital TV coaxial cables. CATV coaxial cables use double shielding to transmit TV signals, ul 758 cable while digital TV coaxial cables use four shielded cables to transmit TV signals. . Generally speaking, the greater the number of shielded cables, the smaller the loss when transmitting TV signals, and the stronger the anti-interference function.
3.Network cable
Network cable is also a kind of weak wire, which can be mainly divided into three types: twisted pair, coaxial cable, and optical cable. Optical cable is the most advanced type of network cable. This network cable has the strongest anti-interference and the fastest network signal speed. Capacity is also the largest; while coaxial cable and twisted pair have slightly worse performance.
4.Audio and video cable
Audio-visual cables are lines used to transmit music signals and video signals. They generally include three types: audio cables, audio cables and audio and video cables. In an era when computers were not yet popular, audio-visual equipment was a common device used by people to listen to music and watch videos. The normal use of audio and video equipment is inseparable from the audio and video cable. Only if the audio-visual cable is installed at home can the audio-visual equipment be used normally.

As the saying goes, the elderly become children when they grow old, and children grow up and become adults. We should treat the elderly as carefully and seriously as we take care of children. The incidence of Alzheimer's disease 專注力不足解決方法is relatively high among the elderly, and it has a very long incubation period. If many of the precursors are ignored, the best treatment period will be missed. What are the signs of Alzheimer's disease? Let us find out next.
What are the signs of Alzheimer's disease?
1. Memory becomes worse
As age increases, people's memory will gradually deteriorate. This is a normal physiological phenomenon. Many elderly people will experience poor memory. However, there is a certain difference between age-related memory loss and memory loss caused by記憶力衰退原因 early Alzheimer's disease. Because of the memory degradation caused by age, after forgetting something or someone, you will slowly recall it through reminders. However, the memory degradation caused by Alzheimer's disease makes it difficult to remember after forgetting, and it is difficult for others to remind you again. As the disease progresses, memory will become worse and worse, and many things, including common or familiar people in daily life, will be forgotten. Elderly people and family members must pay more attention to this matter. If memory loss occurs, observe it temporarily. If it's important, go to the hospital as soon as possible.
2. Reaction becomes slower
As we age, various functions of the body will decline, and slow response will 記憶力衰退原因also occur. However, our slow response caused by Alzheimer's disease also has many other symptoms. Patients may develop a world-weary mentality and may become more silent and less talkative, even leading to depression. If these systemic symptoms appear, combined with slow response, it is very likely that you have Alzheimer's disease. People around them must pay close attention to changes in the physical structure and psychological environment of rural elderly people. Early detection and timely and effective treatment are top priorities.
3. Feeling bad
As they grow older, older people should have a gentler temperament because their experiences have made them more open-minded when facing many things. But what if the elderly suddenly become more and more childish. They are very capricious, prone to bad emotions, and often become very excited, which should attract people's attention. As people age, their nerves deteriorate, and these changes leave them unable to control their mood swings. Many older people become irritable, depressed, and withdrawn. Don’t ignore the symptoms of older people, which may be the cause of latent Alzheimer’s disease.
When there are elderly people at home, you should pay close attention to any sudden changes in the elderly person's condition and treat them promptly. It would be irresponsible not to attribute all changes to aging.

The important impact of PCB layout on PCB to a certain extent determines the manufacturing, installation and subsequent maintenance costs of PCB.1oz vs 2oz In the trend towards high-density electronic design, the PCB layout and routing of each electronic product is particularly important. PCB routing design can often achieve a higher layout rate, reduce jumper distribution, electromagnetic interference between connections, and effectively reduce noise generation.
For years, PCBS seemed to be "relegated" to the field of electrical engineering, becoming unsung heroes behind the scenes. Executives think of PCB wiring as a small manufacturing problem that design engineers don't care about, but as digital circuits become faster and RF circuits are added to PCBS, boards have become a limiting factor in many designs.how to test a circuit board with a multimeter While computer-aided design (CAD) tools can help engineers design circuit boards, CAD's automatic wire winding function often creates more problems. .. .
As with all new technologies, it takes a long time for engineers to accept and popularize printed circuit boards (PCBS). Nowadays, almost all electronic products are made of PCB.
But over the years, PCB seems to have been "downgraded" in the field of electronic engineering, becoming an unsung hero who only quietly works hard behind the scenes. Management believes that PCB routing is a trivial manufacturing issue that is not the concern of design engineers; But as digital circuits change faster and faster, RF circuits are also being put into PCBS, and the circuit board has become a limiting influence on many designs. While computer aided design (CAD) tools are available to help engineers design circuit boards, CAD's automatic winding function design often creates more problems.
PCB layout
PCB Printed circuit board layout
PCBS play a central role in design work, and new ways of designing and manufacturing PCBS are constantly being sought. While our industry peers were still discussing the instruction cache architecture for the 68020 chip, they were already talking about board wiring and prototyping that could be done overnight.
"In my 40 years of electronics design experience, the circuit board has always been the limiting factor that hindered every design project; "You shouldn't just do circuit diagrams to cope with your job. You have a higher responsibility to look at the circuitry that is translated into products that can be manufactured and sold.
Modern PCB is not only a time killer, but also a key component with precise design requirements, with the increase and decrease of electronic equipment operating frequency and signal time, PCB becomes more and more important. Look at these short stories that actually happened and you will get some inspiration.
A printed circuit board story about a flying fighter
Design of radar jamming device for F-16 fighter aircraft. It is understood that some companies may also encounter systemic printed circuit board problems. Circuit board wiring was considered a mechanical engineering task, so our electronics engineers threw the circuit diagrams to other departments to do the circuit board wiring work.
The printed circuit board I got had a very high speed emission Coupled logic (ECL) oscillator, but the 8 layer prototype didn't work because there was enough space in the layers and I wanted to know how they were designed. Smashed to pieces. Originally, to simplify the design of the various parts of the aluminum radiator, mechanical engineers arranged the parts according to their shape, with the ECL chip in the top left corner of the board, the resistor in the middle, the crystal oscillator on the right, and the lower Angle exactly 8 inches from the ECL chip.

So many teenagers wonder why some of their classmates don't get acne as adults and why they can't stop their madness. In fact, there are many reasons that deserve our attention.
First, why do I always get acne when others' faces are white and beautiful?
Generally speaking, people with oily skin are more prone to acne.
This is because their facial oil secretion is exuberant, and the oil is sticky and easily contaminated with airborne dust. This dust clogs the pores, 面部暗瘡 making it impossible for the dirt in the pores to be discharged, which in turn breeds a lot of bacteria, which eventually leads to inflammation and acne.
There is also the issue of sleep, which is closely related to skin! Chronic sleep deprivation or lack of quality sleep will affect the body's metabolism, causing the sebaceous glands to secrete excessively, which ultimately clogs the pores and prevents the other sebaceous glands from discharging their secretions, leading to the development of acne.
Poor personal hygiene is also one of the causes of acne. For example, not removing oil from the face and body in a timely manner, or clogging the pores with dirt, can also lead to poor sebum drainage or the growth of bacteria, which in turn can lead to the development of acne.
In addition, acne is also hereditary, and the extent of its influence is controlled by the relevant genes. In other words, when one of the parents has acne, the probability of their children suffering from acne will also increase.
Some people may say that acne is also a problem, so why is it not effective even after intentional intervention? Adolescents, in particular, are in the age of beauty and are very concerned about these things. In fact, teenage acne recurrence is not good, mainly because of these reasons.
Second, teenage acne recurs, may be due to these reasons.
When teens are faced with acne, the most "rude" way to get rid of it is to suck it out. What they don't realize is that the phrase "more and more people are squeezing" is actually not a lie, because when we squeeze acne, we can't guarantee hygiene. When we squeeze it out, it is equivalent to a skin rupture, which in turn gives bacteria a chance to take advantage of the situation,暗瘡消炎藥 and instead, it accelerates the spread of inflammation.
In general, if you have to squeeze out a pimple, you can go to a dermatologist to seek medical help, or go to a regular beauty salon to get rid of acne professionally!
Another reason why many people get rid of pimples is that although the surface of the pimples is removed, the root of the pimples is not completely removed because the skin looks smooth on the surface. In other words, because we have not removed the inflammation of acne, the pores are still clogged and the acne bacteria may still exist. So for this work when the same location information is still very easy to be stimulated by the environment and break out.
In addition, we repeatedly rub a place may also cause the same place to keep growing acne.
For example, when we lie on our side, the same part of the skin will always rub against the pillow, or the hand will often hold the chin. This is because prolonged friction or touching can stimulate the skin to secrete oil, or cause minor damage to the skin. In addition, there are also germs in the contact areas, such as pillows and hands. These factors may trigger the recurrence of acne.
In conclusion, acne is normal, and there are several reasons why we can avoid it, except for the rise in hormone levels during puberty. When we want to deal with acne, we should try our best to choose regular medical institutions and beauty salons to carry out reasonable treatment. Squeezing acne by ourselves will not only have little effect, but may even aggravate the infection.
Then in our daily life, we can also take some measures to reduce the risk of acne, as far as possible to intervene.

Keep your face clean
Our faces are exposed to the air all the time and can easily accumulate dust and bacteria, which can clog pores and lead to inflammation, which can affect acne and cause acne to occur and develop. Therefore, it is important to maintain a clean face, working daily by carefully washing the face, preferably with a non-irritating cleanser.
The towels and clothes that we often contact with our face should also be washed diligently to maintain a clean, and can often be put under the sun, so as to achieve the effect of sterilization.
For people who are prone to acne, avoid using too much oily cosmetics, which will easily absorb the dust on the face and make acne more serious. In addition, pay attention to make-up, clean your skin every night before going to bed, and use fresh skin care products as much as possible.
In addition, appropriate sun exposure is certainly good for the skin, but because of the long time by the sun, the ultraviolet ability to produce damage to the patient's skin, resulting in its melanin deposits, thereby increasing the metabolic process that makes China's skin abnormal, aggravating acne. So when we go out, if necessary, we should do a good job of sun protection.
Drinking and sleeping are important ways for the body to detoxify, so for teenagers, drinking more water every day, ensuring enough sleep at night, and promoting the excretion of toxins and metabolism, which can reduce sebaceous gland secretion and reduce the secretion of acne.
Exercise can also speed up blood circulation in the body, which is also a way to promote metabolism. Moreover, when we exercise, the superficial blood vessels will dilate, which will accelerate the elimination of toxins from the skin.
Do not eat stimulating foods in your regular diet, such as spicy foods, which can cause skin irritation and accelerate the growth of acne. Teenagers should also eat less sugary foods, otherwise blood sugar will become higher, blood flow will slow down, and the detoxification rate will be reduced.

A marketable critical illness insurance product must cover the required 28 critical illnesses, as well as 3 minor illnesses. So what are these diseases? The following is a detailed introduction!
First, what are the major diseases included in critical illness insurance?
Critical illness insurance includes 28 mandatory critical illnesses and 3 mandatory minor illnesses, as well as other critical illnesses, intermediate illnesses and minor illnesses defined by the insurance company itself, as follows:
1. 28 compulsory critical illnesses: malignant tumor - severe, more severe acute myocardial infarction, sequelae of severe stroke,Cancer insurance major organ transplantation or hematopoietic stem cell transplantation, coronary artery bypass grafting (or coronary artery bypass grafting), severe chronic renal failure, loss of multiple limbs, acute severe hepatitis or subacute severe hepatitis, Severe non-malignant intracranial tumor, severe chronic liver failure, sequelae of severe encephalitis or sequelae of severe meningitis, deep coma, deafness in both ears, blindness in both eyes, paralysis, heart valve surgery, severe Alzheimer's disease, severe brain injury, severe primary Parkinson's disease, severe third-degree burns, severe idiopathic pulmonary hypertension, severe motor neuron disease, loss of speech, aplastic anemia major, Aortic Surgery, Severe Chronic Respiratory Failure, Severe Crohn's Disease, Severe Ulcerative Colitis;
2. 3 types of minor illnesses must be insured: mild malignant tumor, less severe acute myocardial infarction, mild post-stroke sequelae.
II. Other diseases defined by the insurance company itself:
1. non-essential critical illnesses: severe Schihan's syndrome, left ventricular ventricular wall tumor resection, chronic recurrent pancreatitis, systemic scleroderma, severe rheumatoid arthritis, primary sclerosing cholangitis, Creutzfeldt-Jakob disease,Term Life Insurance ruptured cerebral aneurysm pinch-off surgery, progressive multifocal leukoencephalopathy, severe asthma, severe hand-foot-and-mouth disease, severe facial burns, severe Kawasaki disease, and severe bone marrow anomalous hyperplasia syndrome;
2. Non-Mandatory Medium Conditions: moderate paralysis, pulmonary perfusion therapy for alveolar protein deposition, severe osteoporosis, implantation of an intracerebral shunt, severe obstructive sleep apnea, moderate poliomyelitis, moderate ankylosing spondylitis, moderate Parkinson's Disease, moderate encephalitis or postmeningitis sequelae, moderate systemic lupus erythematosus, moderate brain injury, moderate Alzheimer's Disease, removal of adrenal gland due to adrenal sebaceous adenoma, Moderate progressive supranuclear palsy, single limb loss, etc;

Third, what do I need to pay attention to when buying critical illness insurance?
1. Whether the coverage is comprehensive
Critical illness insurance will protect the 28 kinds of major diseases stipulated by the CIRC, so the number of major diseases covered do not have to be too entangled, the same for minor and intermediate illnesses do not have to over-pursuing the number of illnesses covered, you need to pay attention to whether the types of illnesses covered are highly prevalent diseases. If you are a woman or a child taking out a critical illness insurance policy, you also need to pay attention to whether or not it includes 5 types of female high incidence diseases and 15 types of children's high incidence diseases. 2.
2. Whether cancer is covered more than once
It is not enough to pay for cancer only once in critical illness insurance because cancer not only has a high incidence rate, but also has a high possibility of recurrence and metastasis. Therefore, it is good to have critical illness insurance that can pay for cancer more than twice, and it is even better if the number of times of light and medium illnesses is also more than twice.
3. What is the best benefit ratio?
Critical illness insurance usually pays 100% for critical illnesses, however, some good products have additional benefits for critical illnesses, while the proportion of benefits for intermediate illnesses reaches 60% of the basic sum insured, and the proportion of benefits for minor illnesses reaches 30% of the basic sum insured.
4. Whether diseases are grouped
Many critical illness insurance policies are grouped for the diseases covered, and the best critical illness insurance policy is the one that does not group the benefits, and if it has to be grouped, then it should be seen whether the high incidence of some diseases are evenly divided into each group.

Many of you have eaten loofah, but did you know that loofah can also be made into a loofah? It's actually made from some normally aged loofahs, and it's an easy vegetable to grow, especially easy to grow, they'll crawl around the house,cellulose sponge cloth manufacturers and can be kept blooming and fruiting vigorously just by standing up and letting it attach and grow.
The loofah is a squash plant in the cucurbit family with very colorful flowers and is related to the loofah pumpkin, cucumber, and melon.
Usually grown in subtropical regions, the loofah's fruit can not only ripen on the vine,natural loofah sponge wholesale but slowly turn a green, yellow or brown color, and eventually the melon wilts.
When the loofah wilts, it leaks out some very hard fibrous tissue. These make great natural sponges.kitchen scrubber manufacturer These sponges are very hard and resistant to abrasion and are great for washing dishes, faces, bodies, and even floors or cars.
Loofahs are a very popular fruit and vegetable in many parts of the world. It has a great flavor, is very nutritious and grows exceptionally well. It takes a very long time to fruit and the fruit cannot be harvested until the frost is over.
Loofah likes plenty of light and can grow in semi-shade, it can grow well in exceptionally bright conditions, cultivate the soil to keep it moist and avoid prolonged drought.
The soil in which loofahs are grown should be rich in humus, and it's a good idea to add more compost or well-rotted manure to it so that they can produce more and better fruit.
Loofah in the growing process to maintain a perennial warm, avoid freezing, in addition, we must problem to pay attention to it to build shelves, so that the loofah has a place government can climb to grow, so as to effectively promote the branches and leaves to grow demand for vigorous, conducive to the flowering of the research results.
The loofah needs a longer ripening season to maintain a warm environment throughout the year, if it is in the north, it is best to sow seeds in winter and transplant them outdoors in spring.
Cultivating loofahs is also easy. You can just buy some watermelon seeds and sow them in the spring. There are many varieties of loofahs, more than ten common ones.
Do not pick the first loofahs when they are ripe. You can pick them after they have slowly turned green and yellow and finally brown and completely wilted. At this point, you can remove the skin and remove the fibers inside, and there will be some seeds to collect, which you can use for sowing next time.
The loofah sponges you get can be soaked in water to soften them slightly. After clearing the water, the loofah sponge can be exposed to the sun, turning it regularly. After even exposure to the sun, you can dry it completely and store it in a cloth bag for many years.
You can use loofah to wipe all kinds of things, it is a very important and practical natural sponge, after drying technique loofah can also be used to make table mats, shoe mats, sandals or other products.

The duration of lovemaking has always been an issue. Why? Because many people believe that the longer sex lasts, the more friction and intercourse between the male and female sex organs, the more pleasure and delight it produces.best app controlled sex toy Some people even believe that only prolonged sex can satisfy women. The truth is that the duration of sex is not the most important thing, nor is it a guarantee of orgasm and sexual pleasure. But time is ultimately the foundation of sex, so the job of how to prolong it and how to improve a man's fighting ability is crucial. Today, I will tell you what to do:.
1 A complete sex life needs a beginning, a process and an end, and time is calculated from these three aspects. best app controlled sex toy If the process of sex is short, then extend the beginning. Foreplay is the beginning, even if a man has only 10 minutes in formal sex, it can achieve the desired effect.
2 men in the sex life of the movement system frequency is very delicate, too fast,best app controlled sex toy easy in a short time can reach a climax; too slow, men and women will learn to learn not to feel pleasure. So, keep changing the frequency of movement time is our ideal method. When the man is about to climax, immediately by reducing the use of frequency, adjust their breathing and then continue to educate for.
3 The simplest delay technology is to choose some auxiliary gadgets, but do not use blindly,best app controlled sex toy you can choose condoms and other conventional products, so that both to ensure safety, but also effective in prolonging the sex life time, increase the effect.
4 Lowering the center of gravity can save energy and relax tense muscles. Let her run for you for a period of time, some redeeming position is a good choice.
5Use tips. Men play a dominant role in the length of sex, which can be increased by some techniques, such as reducing sexual arousal at orgasm, reducing erection, and effectively controlling early ejaculation. During intercourse, some techniques can be used to reduce sexual tension and delay orgasm.
6 Exercise regularly. Exercise can improve blood circulation throughout the body, including the sexual organs, so that sexual activity to achieve a breakthrough in quality, best app controlled sex toyhalf an hour of jogging or walking every day, at least three times a week, will increase the time and frequency of sexual activity.
The last thing to be especially need to explain is the length of sex time, should be able to do their best, do not just for a moment of pleasure and affect the health of the enterprise. Perfect sex is certainly every are pursuing, but healthy sex is even more important. The biggest design purpose of sex is mainly one for their own pursuit of a kind of pleasure, if a long time sex will bring pleasure will also reduce, then so there is no meaning of sex.
