疲劳

It was found that with the increase in the oscillating frequency for a fixed oscillating angle, the film thickness increases, which may contribute to the formation of the oil film; however, the maximum pressure and the pressure scope during an oscillation cycle also increase; which may shorten the fatigue life of the bounding surface in the latter situation.

结果表明：在摆程不变的条件下，膜厚随摆动频率增加而增大，有利于润滑膜的建立，但同时会增加1个周期中的最大压力及压力波动幅度，使工件易于疲劳；对于相同凸度量，在低频摆动工况下边缘效应较高频工况下的严重，因此在低频摆动工况下使用滚子设计时需要增大其凸度量。

On the basis of that,the structure and function of a new Russian drill pipe flaw detector with electricity bow wave are introduced.

概述钻杆柱疲劳裂纹检测的意义和在电涡流传感器原理的基础上，介绍了俄罗斯专家开发的新型电涡流式钻柱无损探伤仪的组成结构，功能。

The tone contour switch adds brashness to the top-end when on 'contour' and makes for a wearing listen.

打开音调开关，会给高频增加一种粗砺感，使人听着觉得疲劳。

The braze alloy evaluated was also found to degrade fatigue properties under certain conditions of test.

刹车合金的评价还发现，在一定条件下分解疲劳特性试验。

Other possible symptoms include breathlessness, loss of appetite, fatigue and weight loss.

其他可能的症状包括呼吸急促，食欲不振，疲劳和体重减轻。

No adverse effects were reported with the exception of fatigue and breathlessness in participants in one study.

在一项研究，在参加者里，除疲劳和闷热之外，没有反作用被报告。

There may also be chest pain, dizziness, light-headedness, fatigue and breathlessness.

The fatigue life of case house bridge crane in BISC is calculated as an example in this thesis.

本文以宝钢炼钢厂炉前桥式起重机为例，对其主梁的疲劳寿命进行了计算。

The rhythm of the work song of the boatman in Xiajiang is brisker , it is not outstanding that the power of the beat is compared with, to is it count comparatively flexible to take small matter, present repeated dense wave type move forward constantly, melody change range to be relatively little.

在这样的集体体力劳动过程中，船工号子主要起统一步伐、统一意志、鼓舞情绪的作用。如果没有这类歌声来激发船夫们的斗志，统一步伐，那么是很难渡过险滩的。船工们唱起号子来了，就忘了疲劳，正所谓"不喊号子不起劲，打起号子抖精神"。

For example,brittle materials are considered to be unacceptable where fatigue is involved.

例如，脆的材料被认为在存在疲劳的地方是不能够被使用的。

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