在文献[1]中叙述了小型拉伸試样輻照罐的設計和小型不銹鋼拉伸試样的輻照温度的測量。对于后一部分我們提出如下几点意見与作者商榷。1.試驗中所用的銅-康銅热电偶在沸水中进行了校驗,冷端置于15℃,得到热电势3.61毫伏(99.4℃)。众所周知,热电偶的温度-电势关系曲綫(以下簡称温度曲綾)在很大程度上取决于材料的成分,若热电偶材料的成分有較小的变化,就可能引起其温度曲綫的很大改变,例如
In [1] the design of a small tensile specimen canister and the measurement of the irradiation temperature of small stainless steel tensile specimens are described. For the latter part we put forward the following comments with the author to discuss. 1. The copper-constantan thermocouple used in the test was calibrated in boiling water and the cold end placed at 15 ° C gave a thermopower of 3.61 mV (99.4 ° C). It is well-known that the thermocouple temperature-potential curve (hereinafter referred to as the temperature curve A) depends largely on the composition of the material, if the composition of the thermocouple material with small changes, it may cause a large temperature curve Change, for example
