本文介绍了近十年来美国在环境试验理论和方法方面的发展,着重介绍了环境试验标准剪裁、综合环境试验和环境应力筛选的发展过程。指出当前美国在环境试验方面力求更合理地制定环境试验要求,努力把环境试验与产品整个研制过程更紧密地结合起来,从而使环境工程对产品的质量和可靠性保证起到更大的作用。 This article describes the development of the United States in the field of environmental testing theories and methods in the past ten years. It highlights the development of environmental testing standards tailoring, integrated environmental testing and environmental stress screening. It is pointed out that at present, the United States strives to make environmental test requirements more reasonable in environmental tests and tries to combine environmental tests with the entire product development process more closely so that environmental engineering plays a greater role in ensuring product quality and reliability.
