Study on electrostatic shielding performance measurement of anti-electrostatic packaging materials;

Through illustrating electrostatic shielding,the author introduces the principle of isopotential uniform used in high-voltage live working and the application of electrostatic shielding in industrial electrical equipment,and studies the reason why man hasn't dangerous during sparkling,in order to improve the knowledge of people on isopotential uniform and popularize its application.

And it comes to a conclusion that electrets can be made not only into a kind of material providing homogeneous electric fields but also into a kind of ventilative electrostatic shielding material.

This paper analyses in depth conductor s shield principle, points out it is different from electrostatic shield of conductor, and explains why fibre transmission possesses more credibility.

The results show that the height and angle more impact the distributional characteristic of magnetic field in inductor than load does,and the distance of the screen with inductor also impact the characteristic of magnetic field.
