Work period of current is big, copper wire high temperature (550 degrees), if the working section has air exist, copper and oxygen in heating conditions produce copper oxide.

工作段电流大，铜线温度高(550度左右)，如果工作段内有空气存在，铜和氧气在加热的条件下就产生氧化铜。

Test results show that the method can simulate turbine blade key section "s working" stress field "and temperature in the laboratory and give reasonable life data for turbine blade."

试验结果表明：试验方法能够模拟涡轮叶片考核截面在实际工作状态下的应力场和温度，利用所提出的试验方法和分析技术得到叶片的寿命数据是合理的。
