浅议Maxwell电磁理论的适用限度

A study on the available range of Maxwell's electromagnetic theory

Maxwell电磁理论用于线度可趋近于零的粒子时 ,会出现“发散困难”和带电粒子“自行加速困难”。浅释了在什么样的限度上将出现上述两个困难。

When the Maxwell’s electromagnetic theroy is used in the charged particle as its diameter approaches zero, there will arise two difficulties. One is a diffusible difficulty,that is,Coulomb′s energy of Charged particle asymatotically tends to limitless U 0→∞ as the radius of the partide approaeh zero r 0→0,and the another is a difficulty of automatic speeding up of Charged particles.This paper explains the available range of maxwell′s electromagnetic theroy.
