正当人们在充分享受电磁科技迅猛发展所带来的无限便利时,电磁污染这个无形杀手也不期而至.它虽然看不见、摸不着、嗅不到,但却不断地对人类的健康、生产和生活产生着巨大的影响. 1.什么是电磁污染 电荷的周围存在着电场,运动的电荷会形成磁场,而变化的磁场又会形成电场,电场和磁场的交互变化产生电磁波.电磁波在空中传播时就会形成电磁辐射.超过人体承受或仪器设备容许的电磁辐射称为电磁污染,又称频谱污染或电噪音污染.
Just as people are fully enjoying the inexhaustible convenience brought about by the rapid development of electromagnetic technology, electromagnetic pollution is an invisible killer. It is invisible, intangible, and inaudible, but it is constantly improving human health and production. And life has a huge impact. 1. What is the electric field around the electromagnetic pollution electric charge, the movement of the charge will form a magnetic field, and the changing magnetic field will form an electric field, the electric field and the magnetic field will produce electromagnetic waves in the interactive change. Electromagnetic wave propagation in the air Electromagnetic radiation is formed when it is exceeded. Electromagnetic radiation that exceeds or is tolerated by humans is called electromagnetic pollution, also known as spectral pollution or electrical noise pollution.
