A.問題的提出在电工零件中,处于电場影响下的材料的性質,对于零件工作的安全性起决定的影响。而在很多情况下电介質的負荷常常达到了原子物理性質所决定的界限。例如,在电解电容器中介电層受到了強达10兆伏/公分的电場作用。但是只有在能够維持損失(例如漏电)低的情况下,將电能儲存在电介質中才有意义。由于电能是集中在作用于电介質的电场里,所
A. Problem Proposal In electrical components, the nature of the material under the influence of an electric field plays a decisive role in the safety of the part’s operation. In many cases, the loading of the dielectric often reaches the limits dictated by the atomic physics. For example, in electrolytic capacitors, the dielectric layer is subjected to an electric field of up to 10 MV / cm. However, it makes sense to store electrical energy in the dielectric only if it is able to sustain losses (such as leakage) low. Since electric energy is concentrated in the electric field acting on the dielectric,
