According to this result, selftempering temperature of the bar under different control cooling condition was calculated, the process parameter affecting the selftempering temperature is obtained.
Be not allowed to have denied that he is really not a all-round vanguard of technology now, but time for 4 years is enough for him to dawdle away temperingself with fire.
不可否认,他现在并不是一个技术全面的前锋,但四年的时间足够他磨炼自己的了。

Raise the self-controlling ability of the transmission and heat-treatment system, and expanse the infra-red ray detection on the export of the tempering furnace.
