1.前言高温应变测量与超音速飞机和发动机的研制有关,并随之发展而开始了其研究和调查工作。其成果是在1957年ASTM STP230《高温应变片论文集》的出版。随后,希望把电阻应变片用于高温下的要求更高了。随着宇宙开发和原子能利用的进展,高温应变测量越发成为一个现实的问题。为此美国宇航局(NASA),能源开发局(ERDA)等政 1. INTRODUCTION High-temperature strain measurement has been linked to the development of supersonic aircraft and engines and has since started its research and investigation. The result was the publication of ASTM STP230 “High-temperature Strain Gazette” in 1957. Subsequently, the hope of using strain gages at high temperatures is even more demanding. With the progress of space development and atomic energy utilization, high temperature strain measurement becomes more and more a realistic problem. To this end NASA (NASA), Energy Development Agency (ERDA) and other political
