maximum temperature

By changing the maximum temperature and the heating rate in the thermal cycles, this work use Uddeholm self-controlled fatigue experimental method to test the thermal fatigue property of 3Cr2W8V, which has been pre-treated with different heat treatment method.

本文采用Uddeholm自约束热疲劳试验方法,通过改变热循环过程中的上限温度以及加热速度,对经过不同热处理工艺的3Cr2W8V钢进行热疲劳试验;借助金相显微镜、扫描电镜等分析手段,研究了各试验参数对3Cr2W8V钢热疲劳性能的影响。

The upper limit of the coupling degree is given in this paper as K 16mi=1f i-M,so the conjecture in is proved and extended.

给出了运动链耦合度Κ的上限为 :K 16 mi=1fi-M ,从而证明并扩展了文献 [1 ]中所提出的猜

No evidence is found for the above decays, therefore, the upper limits at 90% confidence level are set.

没有发现信号,给出90％置信水平的上限。

Then we prove that to n teams, the upper limit of number every team separated in the middl.

首先对于 5支球队的比赛 ,给出了一个各队每两场比赛中间都至少相隔一场的赛程 ,然后证明了当n支球队比赛时 ,各队每两场比赛中间相隔的场次数的上限是 [(n -3 ) 2 ] ,在达到以上上限的条件下 ,利用轮转模型及其扩充编制了n =8和n =9的赛程 ,并编程实现 。
