前言目前无线电整机,特别是使用在恶劣环境条件下的军用仪器装备,比如各种类型的电子计算机、火控指挥仪器、雷达、通讯设备、测试仪器及仪表等均严重的存在着可靠性不高,环境适应性能较差等质量问题。由于这些问题的存在,不仅直接影响其使用效果,造成大量的浪费,而且在许多场合下还会产生十分严重的后果。为此,如何提高无线电整机的可靠性和环境适应性能,已成为人们十分关心的课题。通过对各类无线电整机的故障统计和失效机理的分析,发现在影响整机可靠性的诸因素当中,因环境因素(太阳辐射、风砂、雨淋、大气污染因
Preface At present, radio machines, especially military equipment used in harsh environmental conditions, such as various types of electronic computers, fire control commanding instruments, radar, communications equipment, testing instruments and meters, etc. are seriously unreliable High, poor environmental performance and other quality problems. As a result of these problems, not only do they have a direct impact on the effectiveness of their use, resulting in a significant amount of waste, they also have very serious consequences on many occasions. To this end, how to improve the reliability of the radio and environmental adaptability has become a topic of great concern. Through the analysis of failure statistics and failure mechanism of all kinds of radio machines, it is found that among the factors that affect the reliability of the whole machine, environmental factors (solar radiation, wind sand, rain, air pollution
