摘要
微波是波长从1米到1毫米甚至更短的电磁波,它的上端与超短波、下端与红外线相衔接。这一波段的电磁波有其特殊的物理特性和传输特性,因此广泛应用于通信、电视、雷达、遥感遥测、天文、气象、工业、农业、生物、医学、科学研究等领域。由于微波对人体有一定的伤害,因此在使用微波技术时要进行正确的防护。
Microwaves, a kind of electromagnetic waves have wavelength, between infrared and ultrashort waves, range from 1mm to 1m. They have special physics and transmission property , and are applied in many fields such as communication, radar, television , remote sensing, remote detection, astronomy, meteorology, industry, agriculture and scientific research ,etc.As microwaves do some harm to people. We should apply with proper protections.
