本文对高温应变片的灵敏系数,热输出、零漂和蠕变及贴片工艺均按现场测试的要求作了简要的说明,并指出注意事项。在此基础上,进一步对现场热应变测量误差进行分析。文中对测量误差的一些具体估算方法具有一定的实用价值。 In this paper, the sensitivity coefficient of high temperature strain gauge, heat output, zero drift and creep and patch technology are based on field test requirements made a brief description, and pointed out the precautions. On this basis, further analysis of on-site thermal strain measurement error. In this paper, some specific estimation methods of measurement error have certain practical value.
