七、国外对可靠性研究的重视程度如何? 国外对可靠性的研究已有40余年历史。提出可靠性研究是由于第二次世界大战中军用电子装备不可靠,延误了战机。为此,1952年美国在军事工业开始进行可靠性研究,1957年提出产品可靠性指标。60年代,可靠性已广泛渗入到机械系统等领域。 至今,可靠性工程已得到世界各国的重 VII. How important is foreign emphasis on reliability research? Foreign studies on reliability have been more than 40 years old. The reliability study was proposed because military electronic equipment in the Second World War was unreliable and delayed the fighters. For this reason, in the United States in 1952, reliability studies were conducted in the military industry, and in 1957, product reliability indicators were proposed. In the 60s, reliability has been extensively penetrated into mechanical systems and other fields. So far, reliability engineering has been recognized by many countries in the world.
