All indexes in cluytyl alcohol preparation group were better than pyroracemic acid and creatine group. Conclusions: Cluytyl alcohol preparation could enhance blood glucose contents, inhibit protein decomposition, advance sere testosterone levels and prevent myocardial damage. Therefore, Cluytyl alcohol preparation is a ideal drug of eliminating movement fatigue.

二十八烷醇制剂在提高运动性疲劳大鼠血糖水平，抑制蛋白分解，提高血清睾酮水平及防止心肌损伤等方面具有重要作用，是一种理想的抗运动疲劳营养补剂。

Objectives:To find out the features of the sEMG change by analyzing the sEMG signal of sacrospinal muscle fatigue induced by dynamic stress of voluntary contractions for gymnastic athletes.

本文通过分析动态负荷引起的体操运动员竖脊肌疲劳的肌电图情况，找出体操运动员腰部肌肉疲劳的表面肌电图变化特征。

The variance of sheering fatigue failure of surface and the tensile fatigue failure of sub-base under two different wheels was studied, respectively.

研究认为：车轮左右两侧路面疲劳破坏寿命是不同的，并且两侧路面的疲劳寿命差异系数随着横拱坡度的增加而急剧增大；随车辆重心高度的增加而增大。

While sustaining constant force, isometric muscular contraction, the initial past decreasing rate of medium frequency curve, the absolute value of the fitting straight line slope, was increased with the degree of the muscular fatigue. With this rate, it was possible to quantitatively judge the state of the muscular fatigue, reduce the physical consumption and muscular uncomfort of recipients.

在维持等长、恒力肌肉收缩时，f＿曲线初始段下降率（即拟合直线斜率的绝对值）随肌肉疲劳程度的增加而增加，因此希望能用f＿曲线初始段的下降率来定量判断局部肌肉疲劳的状态，以减少受试者的体力消耗和肌肉不适程度。

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。

For fatigue prediction of welded structure is faced not only the general problem of unwelded structure, but also the special difficulty resulted from weld arts. So, study of fatigue acts for wagon body is very important.

由于焊接结构的疲劳寿命预测不仅要面对非焊接结构必须面对的一般性困难，而且还要面对焊接工艺本身所导致的特有的困难，因此，研究我国铁路车辆焊接结构的疲劳行为有重要意义。

Objective: To compare the effects of different doses of astragalus membranaceus injection on fatigue in nerve centre,neuromuscular junction and muscle in hoptoads and mice.

目的：利用已建立的蟾蜍和小鼠中枢、神经-肌接头和肌疲劳模型，比较不同剂量的黄芪注射液对蟾蜍和小鼠中枢、神经-肌接头和肌疲劳的影响。

OBJECTIVE: To explore on the emergence of sports fatigue and investigate the way of eliminating or alleviating fatigue.

目的：探讨运动性疲劳的产生机制和消除或缓解运动性疲劳的方法。

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。
