查询词典 electrostatics

Based on the basic law of electrostatics and the boundary-value problems of Poisson equation, two opposite thoughts of the study that electrets can either be designed to provide homogeneous electric fields or be designed to shield electric fields are discussed.

利用驻极体具有的可任意切割、拼装、黏接的特性，从静电学的基本规律及由泊松方程构成的静电边值问题出发，对驻极体既可对外提供电场又可设计为屏蔽电场的 2个相异思维的研究结果展开了讨论，从而，从理论上指出驻极体既可以制成提供均匀外场的材料又可以制成一种透气性静电屏蔽材料。
