电磁波污染是指天然和人为的各种电磁波的干扰及有害的电磁辐射。由于广播、电视、微波技术的发展,射频设备功率成倍增加,地面上的电磁辐射大幅度增加,已达到直接威胁人体健康的程度。电场和磁场的交互变化产生电磁波,电磁波向空中发射或汇汛的现象,称为电磁波辐射(或电磁辐射)。过量的电磁波辐射就造成了电磁波污染(或电磁污染)。
导电屏蔽塑料是防止静电危害、电磁波污染的一种有广泛前景的功能高分子材料。
Conductive and shielding plastic is one of functional polymer materials which can resist static hazard and electromagnetic wave pollution and has extensive research and application prospect.
电磁波干扰(emi)是愈来愈突出的一大环境污染问题,已经不同程度地影响了人们的生产、生活。
The environment problem of Electromagnetic Interference (EMI) becomes more and more outstanding. This problem has already influenced people's life in different degree.
被动探测使用毫米波辐射计,不发射电磁波,因而没有电磁污染和目标闪烁效应,工作比较隐蔽,不易被发现。
Passive detection uses MMW radiometer, which does not emit electromagnetic wave, has no glitter effect and works snugly.
