微波属电磁波的一种,其频率在0.3～300GHZ。按波长分为分米、厘米及毫米波。按波型分为脉冲波及连续波两种波型。随着科学技术的发展,微波普遍应用于电子工业、国防和科研上,如导弹、火箭、宇宙飞船和卫星通讯,新闻和报纸传真等。在医疗上微波作理疗、针灸,诊治癌症及其他疾病。工农业用于制药,干燥木材、纸张、皮革和粮食、育种等。生活上用微波酿酒和烤面包、糕点、肉类等各种食物。最近还利用微波将太阳能传送至地球上,作为能源使用,受微波辐射的人员相应日增,微波已成为危害人们健康的一种因素,生产及生活环境已严重地被微波污染,因此最近在联合国人类环境会议上微波被列为必须控制的“公害”。
Microwave is a kind of electromagnetic wave, its frequency is 0.3 ~ 300GHZ. According to the wavelength is divided into decimeter, centimeter and millimeter wave. According to the waveform is divided into two types of pulse wave and continuous wave. With the development of science and technology, microwaves are widely used in the electronics industry, national defense and scientific research, such as missiles, rockets, spacecraft and satellite communications, news and newspaper faxes. In the medical treatment of microwaves, acupuncture, diagnosis and treatment of cancer and other diseases. Industry and agriculture are used for pharmaceuticals, dried wood, paper, leather and food, breeding and so on. Life with microwave wine and toast, cakes, meat and other food. Recently, microwaves have also been used to transmit solar energy to the earth. As a source of energy, the number of people exposed to microwave radiation has been correspondingly increased. Microwaves have become a factor that endangers people’s health. The production and living environment have been seriously polluted by microwaves. Therefore, The microwave was listed as a “public hazard” that must be controlled at the Human Environment Conference.
