squirrel Sheldon to Beijing after making soy sauce almost crazy, the door was opened by the door, the window was powered by the window, the car was powered by the electricity, the hands were washed by the electricity, the bag was set up by the electricity, the blackboard was blackboard, the elevator was charged with the electric ladder, and the computer was played by the computer. The most tragic thing is to play the computer. When the earphone is close to the ear, only the ear is flax, with a snap of "snap", the music in the earphone is disappearing, only the noise of the call is left. By contrast, the headset is okay, and the headphone interface of the computer is broken. How do
How do you deal with static electricity? According to the principle of "cutting-edge discharge", Sheldon thinks that static electric breakdown is easy to occur at the tip, and the reason why the finger is very sharp is because of its fingers, so it is good to transform his hand into the symmetrical structure of A dream.
this is obviously a stereotyped thinking of theoretical studies. As you noticed, the shell shell question and answer column just gave an answer. And the squirrel's friends web site for a few minutes, also made a small film to teach you how to prevent static electricity: how

static electricity is the electrical phenomenon that we first came into contact with in textbooks. Fur rubbed rubber sticks, silk friction glass rods, these are one of the earliest physical experiments we have ever seen. The static electricity in life is the same, and the friction with the insulated clothing makes the body with a small amount of charge, the dry air is very weak, and the charge is hard to be released. When the charged person tries to touch the conductive metal, the free charge in the metal is redistributed in the action of the charge of the human body - the same-sex repellent. Therefore, the charge on the surface of the metal is opposite to the electrical property of the fingertip, and a strong electric field is generated on the surface and fingertips of the metal. As you know, air is not an "absolute" insulator. If the electric field is too strong - up to about 10 thousand volts (10kV/cm), the thin layer of air in front of the finger is penetrated and becomes a conductor for a moment. The charge of human body at this instant (
) understands the process of electrostatic generation and release, and we will not be able to propose solutions.
first, start from the source. Why do some people get electricity one hundred times a day, and some people are not often hit by static electricity? It turned out that something was bad in some clothing materials that easily generated and accumulated static electricity. If we have seen the 524th, 525th episode of detective Conan, we will be impressed with the killer's knitted sweater. Therefore, in dry winter, wearing cotton clothes and wearing woolen sweater and chemical fiber clothing will reduce the trouble of static electricity.

[/url:3e5yfbtd]next can start with the release of static electricity. Why is it not easy to produce static electricity in summer? That is because in summer, besides wearing woolen sweaters, the air is also humid and conductive. It is easy to release the electric charge produced by friction. Therefore, we can increase indoor air humidity and use laundry softeners to wash clothes, making the surface of clothes easier to absorb moisture.
can also start with alleviating human pain. If you don't touch the fingertips and touch the metal with the entire palm or arm, the electric charge is evenly distributed on the non sharp surface, and the electric field is small and it is not easy to break through the air. At the same time, the current density of contact with the metal in the palm of the hand is much smaller, and it is not easy to feel pain.
here, [url=http://songshuhui.net/archives/author/halin/: 3e5yfbtd][color=#e3881c] squirrel Harlem Yu [/color][/url:3e5yfbtd] objected: "any dielectric (insulator) has its own breakdown electric field (Breakdown field). It seems that the finger is more sharp than the elbow and the charge density is greater, so the electric field between the latter and the conductor is naturally weaker than that of the elbow. But at a small scale, at the very moment of discharge, the tip is also an atom.
this method has been improved in vivo experiments on squirrel Sheldon, but the results are not satisfactory. Moreover, people wear heavy clothes in winter, and only their hands are exposed. They can not release static electricity with their elbows. So, what's the good way to do it?
[url=http://songshuhui.net/archives/author/you.mu.q/: 3e5yfbtd][color=#e3881c] squirrel bathe right [/color][/url:3e5yfbtd] introduced personal experience: "touch the wall with hand, I do it." It turns out to be so simple! When you touch the wall with your hands, the walls do not generate many induced charges unlike metals. Therefore, no air breakdown occurs. The size of the current is not enough to produce pain. But, if a person wants to know whether he has static electricity, and does not want to be hurt by static electricity? This method is to take one of the keys with your hand and contact metal objects with the other tip - doors and windows, cars, armrest, faucets, blackboard edges, and trash cans. The key will not pain, the current is scattered on the contact surface of the finger and key, not only can see the electric spark to hear a "snap", but also do not need to feel a trace of numbness, it can be described as the best of the best.
the method of eliminating static electricity has been found. Then we would like to ask whether electrostatic will have adverse effects on human health. If you've searched the Internet, it's probably not a stranger:
"the probability of facial erythema, pigmentation, and other facial diseases on the computer's office white-collar workers is far higher than the non computer, because the static electricity generated by the computer screen attracts a lot of suspended dust to make the face suffer. The stimulus is caused. "
for this statement, [url=http://songshuhui.net/archives/author/bobo/: 3e5yfbtd][color=#e3881c] squirrel BOBO[/color][/url:3e5yfbtd] explains, "this kind of 'nonsense' can be played all the way. In fact, it is not certain that the so-called electrostatic attraction of dust causes facial irritation. It is very likely that those who use computers do not pay more attention to life habits, do not pay enough attention to drinking water, and sleep less, leading to endocrine disorders. However, people who implant cochlea should try to avoid exposure to static electricity. "
[url=http://songshuhui.net/archives/author/you.mu.q/: 3e5yfbtd][color=#e3881c] squirrel on the right [/color][/url:3e5yfbtd] added: "serious static can make people dizzy, if the skin is moist, it will be easier, with a heart pacemaker and the like to be careful. In fact, the current through the human body can also affect the work of the heart or nervous system, this essentially is not much different from the electric shock, the main difference is that the static electric strike is the instantaneous current.

[/url:3e5yfbtd] says that people are afraid of static electricity, but the machines are even more afraid of static electricity. Integrating many tiny electronic components into an integrated circuit, even if it is hit by static electricity once, may cause the whole integrated circuit to be scrapped. I wonder if you have noticed that the electronic components on the market are usually covered by a layer of grey antistatic plastic. The conductive material is added to the plastic layer, so that the current can be shielded outside like the "Faraday cage" to protect the electronic components from being affected. In places where flammable and explosive materials are around, static electricity is very dangerous and there is a possibility of fire. In such a place, in addition to wearing conductive antistatic shoes, we must strictly comply with the corresponding procedures and regulations. Detective Conan is a good antistatic teaching film. You may as well take a look.
