According to the feature that deformation resulted from water absorption and mildew appear mainly on the rabbet surface of ccf , this paper adopts rsst to spray a special waterproof sealant on rabbet surface of ccf , so that the sealant can get into fiberboard to certain extent by means of capillarity and penetration , blockage the holes between fibers and capillary , cut up passage of water and change the properties of soakage and sorption to water in capillarity and fiber . at the same time , solidified sealant can form a compact waterproof pellicle on rabbet surface so as to prevent water and humidity from fiber ' s expansion and mildewing

针对吸水变形、霉变主要发生在地板企口表面的特征，采用企口表面全封闭法，在复合强化地板企口表面喷涂特殊的防水封闭剂，使其依靠毛细管作用及渗透作用进入板内一定深度，堵塞木纤维之间的空隙及毛细孔通道，截断水分传递的渠道，并改变毛细孔壁及纤维的表面性质以不利于水的浸润与吸附，同时其固化后能在企口表面形成一层致密的憎水薄膜，防止水分、湿气从企口侵入板内引起木纤维膨胀变形、发霉等现象。

To the crack in the rail surface, the effect of longitudinal location on the distribution of the elastic-plastic stress and strain in the railhead is calculated. The maximum stress around the crack in the rail surface over the yield stress and the steel around the crack has plastic strain.

对于条纹状钢轨表面缺陷，主要计算了不同横截面位置条纹状钢轨表面缺陷对轨头内弹塑性应力场和应变场的影响，条纹状钢轨表面缺陷的存在使其周围最大等效应力超过了钢轨材料屈服极限，导致该位置钢轨发生了塑性应变。

It is to our service what oil is to the wheels of a railway carriage.

在主的喜乐使我们刚强，而所发生的作用能排除困难。

Moreover, since the atoms are in random thermal motion the frequency spectrum will be altered by the Doppler effect.

而且，由于原子是在作无规则热运动，多普勒效应也会使频谱发生改变。

I won't say I was the lone bear -- Jeff also sensed wreckage on the horizon -- but the timing, coupled with the intensely competitive landscape, made for prickly friction with a razor-thin margin of error.

我不想说自己是"众人皆醉我独醒"─杰夫对网络股也有不好的预感─但时机把握的重要性，加上公司内部的敏感氛围，使任何一个小错误都不允许发生。

Perhaps the reactivation in these systems is simply not fast enough for this to occur.

或许这些实验系统中再激活作用只是还不够使其发生而已。

The differences of these catalysts reactivity were related to their structures and the activity of lattice oxygen.

这一方面是因为氢的引入使表面的氧物种发生了变化，形成了活性更高的氧物种，另一方面是因为氢的引入加速了氧分子向晶格氧转化。

Results It found that apoptosis was induced in leukemia cells and bcl-2 expression down-regulated by realgar.

结果 雄黄可诱导白血病细胞发生典型的凋亡，同时雄黄可使白血病细胞bcl-2蛋白表达呈时间依赖性下降。

News tells the most recent events. Technology in recording period limits the recency. Live broadcasting approaches the event itself as much as possible. That raises the value of the object being broadcasted.

新闻是对新近发生事实的报道，录播时代的技术手段对"新近"有一定的限制，直播使新闻报道最大程度地贴近事件本身，提升了报道对象的新闻价值。

利用九标度法建立目标集的互反型二元比较矩阵，对其用方根法与乘幂法结合使用，以此求得交通系统各子系统的相对重要度排序向量，找出极易使交通系统崩溃的脆性元件或因素，对其进行重点监测，最大限度避免了脆性的发生，从而为交通系统的脆性研究提供了一种可行的分析方法。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
