| 摘 要： | 在瞬态加热条件下，应变计的瞬时热输出特性与应变计在慢速升温条件的热输出曲线有明显的差别。这种差别随着温升速率的提高将更加明显，本文主要介绍这种差别的试验研究结果。

| Abstract: | There are obvious difference between both the transient thermal output characteristic of high temperature strain gauges in transient heating condition and the thermal output curve of one in slow heating condition. This difference raises with heating rate. In this article we will describe principally the test results for the difference of thermal output. |
