The vibration properties and random fatigue analysis are valuable for steel structure engineering application. By the analysis results, the engineers can consider in depth in the design phase of the steel-framed structures. Steel structure can be optimized based on the results, so that its antivibration performance and life can be improved.

主要振动响应特性分析结果以及随机疲劳的计算分析对钢架结构的设计具有一定的指导和参考价值，可以使工程设计人员在设计钢架结构阶段考虑得更加深入，使钢架结构得以优化，以期提高钢架结构的抗振性能和使用寿命。

Gradation segregation may even be reflected by infrared pictures.Infrared pictures also shown that temperature difference is controlled even behind full-width spreader as transfer car is used.

红外热像反映出使用转运车后，即使是全幅摊铺机温度离析也控制得较好，可见转运车减小温度离析的效果超过了摊铺宽度过大的影响。

We left out Opera Mini and Skyfire, since they both leave most of the hard work to servers which essentially spit out a kind of image file—besides, we don't think this kind of internet-by-proxy browser will be around for much longer.

Opera Mini和Skyfire也没有测试，因为他们是通过服务器的图片渲染模式来处理网页，而且我们不认为这种使用代理服务器来处理网页的浏览器会活得很久。

On the outside of the loop ,the end is vulnerable to snagging. snagging may cause capsizing of knot , resulting in a slip knot.

所以严格来讲若是结尾的绳结打得够够牢(用stopper knot)，并紧贴近原本的称人结，那使用上就没有问题了。

There have been many failures of Mexican health care systems at local levels but keep a few things in mind: a some of the problems lie with citizens who won't go see doctors, or who won't go see non-shaman doctors, b too many Mexicans self-administer antibiotics, and c when there is so much air pollution it is harder to discover flu cases, especially in the midst of flu season there.

墨西哥医疗体系存在很多问题，在地方一级有一些事情是应该引起得起注意的：a）许多问题的根源在于当地的居民不愿意去看医生或者是不会去看不是黄教巫医的医生。b）太多的墨西哥人自己使用抗生素。c）空气污染已经严重到让人很难发现流感事件『估计是几乎很多人都有呼吸道方面的疾病』，特别是在流感高发期。

As to baking Sail, we had none, nor, if we had, could we ha' done any thing with it; so we work'd at the Oar towards the Land, tho' with heavy Hearts, like Men going to Execution; for we all knew, that when the Boat came nearer the Shore, she would be dash'd in a Thousand Pieces by the Breach of the Sea.

我们没有帆，即使有，也无法使用。我们只能用桨向岸上划去，就像是走上刑场的犯人，心情十分沉重。因为，我们知道，小艇一靠近海岸，马上就会被海浪撞得粉碎。

The invention of the wheel and screw, the introduction of steam-power, the use of electricity, all these have changed the lives of millions; but the pen has done more.

车轮和螺丝的发明，蒸汽机的问世，电力的使用，所有这些都曾改变了亿万人的生活；然而，笔却做得更多。

Running faulty and type selection process are introduced for the slurry pump in phosphoric acid tank area, summarization is made for type selection of slurry pump, as well as for application effect after its reformation; by means of reformation for coupling of single screw pump imported, running rate is increased by 1%, phosphoric gain rate is increased by 3%.

介绍磷酸罐区泥浆泵的运行故障和改型过程，总结了泥浆泵选型及改造后的使用效果，通过对进口单螺杆泵联轴节的改造，运转率提高1％，磷酸装置磷得率提高3％。

However, in some installations which use shaking screens for size separation , particularly in sand and gravel or dredge plants, vibration may be so severe that conduit can literally be shaken to pieces .

但是，在一些装置使用摇头屏幕大小分离，特别是在沙及砾石或疏通植物，振动可能会严重得使导线可以从字面上不可动摇的成碎片。
