不疲劳

Chronic fatigue syndrome is a kind of general syndrome under the contemporary fast tempo mode of live with the serial of chronic fatigue syndromes such as the degression in impermanent memory or attention , pharyngalgia , lymphadenectasis or haphalgesia in cervical part or under armpit ,courbature , multi-articular soreness without red swelling of the skin , cephalalgia , somnus unable to recover from fatigue , postexercise defatigation exceeding to 24 hours .

慢性疲劳综合征是现代高效快节奏生活方式下出现的一组以长期极度疲劳(包括体力疲劳和脑力疲劳)为主要表现的全身性症候群，其主要症状表现为短期记忆力或注意力明显下降，头痛，不能解乏的睡眠，运动后的疲劳持续超过24小时。

It tires not nor does it boast of its power; but belongs to the air, travelling it may be six thousand miles to and from its northern nesting home feeding its flown young as it flies and slipping through a medium that seems to help its passage even when the wind is adverse.

燕子充分兼有这两类鸟的长处，它既不疲劳，也不炫耀自己的飞翔力；在空中十分自如，可以飞行6，000英里，可以飞往北方做窝的老家，再从老家飞回；一边飞一边喂养会飞的雏燕，甚至在顶风时也能在气流中滑翔，似乎气流在帮它前进。

It tires not, nor does it boast of its power; but belongs to the air, traveling it may be six thousand miles to and from it northern nesting home; feeding its flown young as it flies; and slipping through a medium that seems to help its passage even when the wind is adverse.

它既不疲劳，也不炫耀自己的飞翔力；在空中十分自如，可以飞行6000英里，可以飞往北方做窝的老家，再从老家飞回；一边飞一边喂养会飞的雏燕，甚至在顶风时也能在气流中滑翔，似乎气流在帮它前进。

The swallow shares the virtues of both schools in highest measure.

Their number follows ,such as partridges,have a like power of strong propulsion,but sooner tire.you may pick them up in utter exhaustion,if wind over the sea drive them to a long distance.the swallows share the virtues of both schools,it tires not ,nore does it boast of its power.it belong to the air.travelling it may be six thousand miles to and from the northern nesting home.

如果海风驱使它们飞行很长距离，你可以捡到一些因筋疲力尽而摔下来的鹧鸪。燕子充分兼有这两类鸟的长处，它既不疲劳，也不炫耀自己的飞翔力；在空中十分自如，可以飞行6，000英里，可以飞往北方做窝的老家，再从老家飞回；一边飞一边喂养会飞的雏燕，甚至在顶风时也能在气流中滑翔，似乎气流在帮它前进。

Medium 的含义是"介质",没有这种"介质"便达不到一定的目的 It tires not nor does it boast of its power; but belongs to the air, travelling it may be six thousand miles to and from its northern nesting home feeding its flown young as it flies and slipping through a medium that seems to help itspassage even when the wind is adverse.

它不知疲劳，也不夸耀自己的飞翔能力，然而它在空中十分自如，可以一直飞行6，000英里。飞向北方的筑有鸟巢的家乡以及从那里飞走，在飞行的过程中还要喂养已出窠的雏燕，甚至在顶风的时候也能够不费劲地穿过那似乎有助它迁栖的气流。

Results of analysis show that Generalized Paris Law can consider the complex crack propagation in the material of the pavement structure. The fatigue life of the pavement increases with increasing thickness of surface layer in a power function. Use of a thicker surface layer may extend the service life of the asphalt pavement. The fatigue life increases with decreasing modulus of surface layer in a power function with a negative exponent. However, since reduced modulus would scarify the structural strength and might cause rutting-related distress, caution should be taken when using low modulus materials for improving fatigue performance of asphalt pavements. The fatigue life increases with increasing modulus of base material in a power function. However, the fatigue life can not infinitely increases with increasing modulus of the base.

计算与分析表明：广义Paris公式可以考虑沥青路面结构内材料复杂的裂缝扩展：沥青面层的疲劳寿命随着面层厚度的增加以幂函数的形式增加，适当增加沥青面层厚度可以提高路面的使用寿命；沥青面层的疲劳寿命随着面层材料模量的降低以负指数的幂函数形式增加；由于材料模量的降低将牺牲路面的整体强度并可能引起路面车辙类损坏，以此提高疲劳寿命的方法应慎重对待；沥青面层的疲劳寿命随着基层材料模量的增加呈幂函数的形式增加，但由疲劳方程可以看出，寿命并不是随基层材料模量的增加而无限的增加，疲劳曲线在经过一个上升段后，逐渐趋于一个常数值，这说明，这时基层模量对寿命已不作关键性贡献；随着底基层厚度的增加，面层的疲劳寿命近似地呈线性函数增加，但效果并不很明显。

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。

By measuring the residual stresses of the cylinder of a cement ball mill in four cases,and the fatique crack spreading for the thermal treatment and the un thermal treatment test samples,the results showed that the heat treatment sample reduced the residual stress,enhanced the fatique strength and lowered the crack spreading speed.

对球磨机筒体的4种情况的焊件进行残余应力测试，并对进行热处理和未进行热处理的试件做疲劳试验及疲劳裂纹扩展测试。试验结果表明：经过热处理的试件，残余应力降低，疲劳强度提高，裂纹扩展速率降低，结构抗疲劳性能增强。不过从工程应用角度看，对于板厚为20～25mm的球磨机筒体而言，不进行焊后热处理也能保证足够的疲劳强度

在美国，慢性酒精中毒，肝炎是最常见的。
