1981年12月15～17日由四机部十四院、清华大学、北京钢铁学院、中国军事医学科学研究院、北京电子管厂、北京钢铁研究院等单位的代表参加,对四机部一四一二所八室的“用激光全息干涉术测定陶瓷—金属封接件热应力”研究课题进行了鉴定。会议听取了该课题的技术报告和工作报告,审阅了全部技术文件和照片,并到现场观看了实验装置和全息底片。会议指出:测定陶瓷—金属封接应力在国内外都是一项难题,由于陶瓷是非透明介质,而且封口狭窄,测量温度高,所以用传统的偏光仪、应变片、拉力计法、热冲击法……都
December 15, 1981 to December 17 by the fourth unit of 14 homes, Tsinghua University, Beijing Institute of Iron and Steel, Chinese Academy of Military Medical Sciences, Beijing Electronic Tube Factory, Beijing Iron and Steel Research Institute and other units to participate in the representatives of the four four-one One or two eight-chamber “laser holographic interferometry determination of ceramic - metal seal thermal stress” research project was identified. The meeting heard the technical report and work report on the subject, reviewed all the technical documents and photos, and went to the scene to watch the experimental device and holographic film. The meeting pointed out: Determination of ceramic - metal sealing stress is a difficult problem at home and abroad, because the ceramic is a non-transparent medium, and sealing narrow, high temperature measurement, so with a traditional polarizer, strain gauges, tension meter method, thermal shock method ……All
