使摆动

A century ago, Edith Wharton enlivened her novels with dozens of bright, if now obsolete, observations about petticoats, leather-bound books and the graceful sway of a C-spring barouche.

一个世纪以前，伊迪丝·沃顿就通过对裙子、皮封书籍以及弓形弹簧四轮马车的优雅摆动的不厌其烦的机灵观察而使她的小说十分生动，虽然现在看来有些陈腐不堪。

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。

"The cylinder of an internal-combustion engine is closed at one end by a plate called the head and open at the other end to permit free oscillation of the connecting rod, which joins the piston to the crankshaft."

内燃机的汽缸在一端用盖封住，叫做头，另一端敞开，使连接活塞和曲轴的连杆能自由摆动。

These pipes have strong gutta-percha articulations, so that the oscillations of the balloon may have no effect on them

这些管子隔一段距离就装有结实的橡皮关节，这使它们能够经受住气球的摆动。

Metallurgy School, UST Beijing, Beijing 100083, China）ABSTRACT The negative thermal expansion in some complex oxides has beenattributed to transverse thermal motion of A-O-M linkage composed of two-coordinate oxygenbridge bond, and the librationsand tilts of essentially rigid polyhedral blocks in openframework structure. The isotopic NTE materials have been finding moresubstantialapplications in composites and other relative technique fields.

氧化物材料负热膨胀机理邢献然摘要氧化物的负热膨胀性是由于在其开放式的骨架结构中，有二配位的桥氧键产生横向热运动，以及引起的多面体热摆动和耦合作用使非键合M-M1键距变短，导致单胞体积缩小；各向同性NTE氧化物在复合材料及其相关技术领域具有更广泛的应用价值。
