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 experimental and theoretical studies of the electron screening effects in charged-particle induced reactions at energies of astrophysical interest are systematically reviewed, and the theoretical discussions on the electrostatic screening effects in the thermonuclear reactions in stellar plasma are also summarized briefly.

We discuss electrostatic screening effect by applying the classic electromagnetism theory combined with energy band theory,considering electrostatic screening effect as electrostatic field screening effect,instead of the electrostatic potential,i.
