一、前言众所周知,在一般电子产品的研制和生产过程中,都离不开环境试验。如高温、低温、盐雾、雨淋、振动、冲击、噪声等,几乎都是必须进行的试验项目。特别是飞机、导弹、卫星上的电子产品,更是如此。只有进行了这些试验,并证明产品在这些环境作用下仍能正常工作,产品才能投入使用。这些试验起初只在军用产品上进行.后来发展到一般民用产品也进行,而且国外早就制定了试验标准,各类产品按照相应的标准来进行试验。在产品的研制阶段有研究性
First, the preamble As we all know, in the general process of electronic product development and production, are inseparable from environmental testing. Such as high temperature, low temperature, salt spray, rain, vibration, shock, noise, almost all of the pilot project must be carried out. In particular, aircraft, missiles, satellite electronic products, even more so. Only after these tests have been carried out and the product is certified to work properly under these conditions can the product be put into use. These tests were initially carried out only on military products.Afterward, the development of general civilian products was also carried out, and the test standards were formulated long ago in foreign countries and all kinds of products were tested according to the corresponding standards. In the research stage of product development
