When particle is close to the metallic electrode, the surface electric field of insulator ascend dramatically. 导电颗粒靠近金属电极时,绝缘子表面电场强度明显大于颗粒在其它位置时的电场强度;
At the same time, this paper presents the numerical analysis by means of the finite difference method. A computer program on the thermal insulation performance of the metallic reflective insulator has been worked out. 同时介绍了用有限差分法进行数值计算的方法,编制了金属反射式保温块隔热性能的计算机程序。
