疲劳地

Secondly the fatigue test is carried out under the constant amplitude cyclic loading for the specimens which are exposed in the corrosive environment for equivalent calendar time of zero year, 3 years, 8 years and 13 years.

飞机结构日历寿命的确定与腐蚀环境对飞机结构寿命的影响紧密相连，材料抗疲劳性能随日历年限的变化规律和腐蚀环境作用后的疲劳累积损伤理论是科学地确定飞机结构日历寿命的基础。

RESULTS:A fatigue determination system which was able to determine effectively the examinee's fatigue state was established.

结果：搭建了一套疲劳检测系统，可有效地得到被试者的疲劳状态。

The results of the tests indicate that the spots where the fatigue short cracks initiated are at the bottom surface of the circle indention and some disfigurement places in that surface. The propagation paths of the cracks are very complex and the decentralization of the obtained data is very severe due to the micro organism of the material. While the distribution of the short fatigue cracks exist self-regularity on their length, angle, density and expansion rate of the cracks, which are less affected by the outer factors.

试验中观察到短裂纹形状多为Z型，试验结果表明疲劳短裂纹往往萌生于试样缺口底部表面和缺口表面缺陷处，其扩展复杂，路径曲折，数据分散性大，强烈地受材料微观组织的影响，疲劳短裂纹在长度、角度、密度和扩展速率方面虽数据分散但具有自身的规律，受外部因素的影响较小。

Not to mention the plethora of italicization and of exclamation points.

书里有太多的副词，像"完全地"、"显然的"、"明显地"、"极度可怕地"、"美国现有的生产能力的第三部分的本质上永远无利用"（见 p26），这些话，真是很让人疲劳，更不必说那些多余的斜体字，以及多余的论点了。

Based on Chaboche's Continuum Damage Mechanics Model, this study suggested low-cycle fatigue damage model under nonproportional loading, in which maximum shear stress and mean hydrostatic stress are considered as two basic parameters and nonproportionality of loading path is considered as a damage parameter to enter damage evolution equation which may well describe damage evolution law of low-cycle fatigue under nonproportional loading.

按Chaboche的连续损伤力学方法建立的多轴非比例加载下低周疲劳损伤模型，以最大剪应力和平均静水应力作为两个基本参量，将路径的非比例度作为损伤参量引入损伤演化方程中，可以较好地描述非比例加载下低周疲劳的损伤演化。

The joint pontes of the front undercarriage of an aircraft is a fatigue critical part,its fatigue life has to be estimated exactly.

某型飞机前起落架后接头连接区为疲劳危险部位，必须准确地估计疲劳寿命。

The joint pontes of the front undercarriage of an aircraft is a fatigue critical part,its fatigue life has to be estimated exactly.

中文摘要：某型飞机前起落架后接头连接区为疲劳危险部位，必须准确地估计疲劳寿命。

It is a great labor for your whole digestive system; and if the digestive system becomes tired, you are going to die soon; and if your digestive system remains untired and young and fresh, of course you can live longer.

你不明白一个简单道理：无论你吃什么东西，你的身体总得消化它……你的整个消化系统为此劳作；如果消化系统变得疲劳，你会更快地走向死亡；如果你的消化系统保持不疲劳、年轻的和新鲜的，当然你能更加长寿。

A full-size fatigue life test equipment for coiled tubing is developed to simulate the conditions of coiled tubing operation in fields.

为了能比较真实地模拟连续管在实际作业工况条件下，即在弯曲和内压联合作用下的疲劳寿命，研制出了一套专门用来进行连续管低周疲劳寿命的实物试验装备。
