摘　　要：为提高电子通信设备的“共存兼容”能力,解决设备中的电磁兼容问题。提出了薄膜屏蔽效能计算分析式的构成,通过对薄膜屏蔽的材料的性能分析,依据Maxwell方程组的不限定形式及其本构关系,研究和分析了导电媒质中均匀平面电磁波的电磁场传播方向及规律。针对金属屏蔽体的基本特点,对4种常用金属薄膜屏蔽体效能进行了理论计算和实践测量。给结出了运算中带有规律性的实践方法,为通信和各类电子系统开发与研制要解决的电磁兼容问题提出了新的途径。In order to inprove the comparability of improving electronic communication equipment, solve the electromagnetic compatibility problem in the equipment. Decay through the even distance of spread of electromagnetic waves of level and energy of propagating in analysis of performance and conductive medium to the Thin-film shield material, according to the shielding efficiency computational analysis of the membrane and basic characteristic of the metal shield body, have carried on the theory and calculated and practised measurement to four kinds of daily metal membrane shielding body efficiency. And has studied practice method with regularity in operation. Study and explore and put forward the new application way for the craft of the Thin-film shield.
