It follows that the greater the difference between the measurements, the worse the stiction.

如果有较差的摩擦，则测量值将产生较大的差距（压下和抬起之间， L2和 L3的差距）。

After they are disconnect ed, the joint with the self-closed function can prevent the outward seawater ent ering, and prevent the inner hydraulic oil drainning. After they are connected, the fluid circuit is opened by the pressure of the fluid.

这种接头具有自封闭功能，在两油路分离后可以防止外部的海水进入管路，也可以防止管路内的液体流出，连接后，在流体压差的作用下，两液路接通。

The results show screw-down tilting is the basic reason of the problem. When there is an obliquity between the shaft sleeve and bush which is caused by screw-down tilting, the load capacity of the bearing drops suddenly.

计算结果表明，压下倾斜过大会造成轴套与衬套的轴线出现倾斜，进而导致轴承的静压承载能力急剧下降，是造成轴承寿命缩短、连轧机启动频繁失败的根本原因。

In the experimentation, the premixed propane-air flame propagation behavior was studied as the following:(1) Study on pressure wave influence on premixed propane-air flame propagation behavior under different pressure relief case The high speed Schlieren photograph method was used to record the dynamic process of flame propagation clearly, including the precise flame front position, flame structure, and so on.

此方法可以运用于整个凝聚体系统，从零压开始计算材料各个压缩度下的压力，考虑到经典TFD模型的统计与真实量子力学统计之间的差异。

A Nor'Easter hit our area two weekends ago, heavy rain and sweeping rain claimed six lifes; with four were crushed from down trees.

上两个周末下了一场两天长的大风雨﹐共六人夜亡﹐四位是被连根拔起的蹋树压死的。

The mechanical model and mathematical models of dead weight and lever support system on bandsaw were set up.

为揭示杠杆压砣张紧系统的内在本质问题。建立了空载条件下的张紧系统的力学模犁和数学模型。

The local journalists dare not take risks. Journalists in Palembang only look for easy news and if they have been 'serviced', bad or critical news will not be published.

当地记者根本不敢冒险，巨港的记者只会去找一些容易的新闻，如果他们收到'好处'的话，什么负面或者非法的消息也都会被压下。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。
