疲劳

The coarsened structure perpendicular to primary crack plane exhibits better propagation resistance than that parallel with primary crack plane, but it seems that crack propagation property at high temperature can not be improved by changing γ′precipitates morphology.

颗粒形态不会改变裂纹扩展路径及微观机制，粗化结构的疲劳裂纹扩展阻力随温度升高而降低的趋势比原始结构剧烈，同时与主裂纹面垂直的粗化结构具有比与主裂纹面平行的粗化结构更好的疲劳裂纹扩展抗力，但通过改变γ′形态似乎不能改善高温下裂纹扩展性能。

Excessive fatigue, familiar clinical manifestation of sub-health, produces plentiful "fatigue toxin" which corrades continually all systems and organs, leads to some serious diseases and accelerates Karoshi's occurrence finally.

出现亚健康就是给健康亮了黄灯，过度疲劳是常见亚健康表现，而&疲劳毒素&长时间、多系统的侵蚀将导致各种严重疾病，最后促进&过劳死&的发生。

The CFS animal model was established by multiple stress factors as chronic enchaining, cold swimming and electric stimulus when taking food.

采用慢性束缚及冷水游泳加进食时电刺激的复合应激方法研制了慢性疲劳动物模型，并经行为学测定，结果与慢性疲劳综合征的临床表现基本相似。

This article discusses the engendering mechanism of sports fatigue and the effective methods to eliminate it.

着重探讨运动性疲劳发生机制以及消除疲劳的有效方法和途径。

I think that we have seen that when he's rested he plays better, when he is not fatigue the knees is stronger and works better, when he fatigues then the muscles aren't protecting the joint as much and there's more stress on the area of the joint surface damage.

我想我们都看到了，当他休息了之后会打得更好些。当他感觉不到疲劳的时候，膝盖感觉更有力更好；当他疲劳的时候，肌肉就不足以保护关节，也就让关节表面受伤的部分承受更多的压力。

In this thesis, the problem is taken as engineering background to study the real-time assessment for the guyed mast'fatigue state, and the corresponding theory and method for it has been put forward .

A model for Reliability prediction of fatigue residual life of composite laminates has been derived based on probability analysis.

应用可靠性分析的方法，导出了层板复合材料在疲劳载荷作用下的疲劳剩余寿命的预报模型。

The results show that the fatigue life of the peened joint is 20～30 times as long as the as-welded joints .Therefore,the improvement of the fatigue strength of welded joints by ultrasonic peening is remarkable.

试验结果表明：超声冲击方法对焊接接头疲劳强度的改善效果十分明显，能够提高疲劳寿命20～30倍以上，极具实用价值。

By the way of X-ray stress measurement, the characteristics of residual stress distribution of specimens, which were shot peened and polished, were studied; by the way of three-point bending fatigue tests, the influence of polishing after shot peening on fatigue properties was studied; on this basis, the reason why Shot Peening Standards provide that the depth of metal removal does not exceed 10% of the specified arc height was analysed.

文中指出300M钢喷丸强化工艺中打磨对喷丸效果的影响问题；通过X射线应力测定，研究喷丸及打磨后试样的残余应力分布及变化的特点；通过三点弯曲疲劳试验，研究喷丸后打磨对试样疲劳性能的影响；在此基础上，分析喷丸标准中规定喷丸后打磨去除量不可以超过阿尔门强度值的1/10的原因。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
