接触面

Why are large soft contact areas such aslead or copper braid usde for surfaces or headstocks?

零件表面通电或夹头通电时，为什么要用大的软接触面如铅或铜锌？

45Hu.The contect surface between the tumor and mediastinum appears as moulten shape in 28 cases.

肿瘤与纵隔接触面呈灌铸型28例，占75.7%。

ABSTRACT Elastohydrodynamic oil film, existing in contact surfaces of parts such as gears, cam—tappets and ball bearings, is a key factor that both determines their wear characteristics and affects system dynamic performance of those parts.

存在于诸如齿轮、凸轮—挺杆、滚动轴承这样一些另件的接触面间的弹流动压油膜，不仅是决定其摩擦磨损特性的关键因素，而且也是影响这些另件甚至系统动力学行为的不可忽视的因素之一。

It is commonly discribed as linear viscous damping, Coulomb friction, stiction or some combination of these.

一般把它描述为线性粘性阻尼、静摩擦、接触面阻力，或这些的混合。

Unfortlmately, attempts to ignore or linearize significant Coulomb friction or stiction, both of which are represented by a discontinuity at zerovelocity (Fig. 1), may lead to erroneous predictions of a system's behavior.

不幸的是企图忽略或线性化重要的静摩擦或接触面阻力（两者都表现出零点的非连续性），可能导致对系统行为错误的预测。

But the overflow pipe is stuck by the bathtub causing gaps between them, so there are some leaking problem at the bottom of the bathtub when testing the sealing performance.

如先将排水管与溢水管组装后再安装于浴缸上方可装上，但由于溢水管与浴缸接触面顶住，会产生些间隙，故在测试密封性能时发现底部有漏水问题。

Making use of ABAQUS, the finite element models are constructed of pile with straight shaft and pedestal pile, with soil modeled as Mohr-Coulomb, piles as elastic, and contact pair built between pile and soil.

利用ABAQUS软件建立等截面桩与扩底桩的有限元分析模型，土体用Mohr-Coulomb本构模型，桩体采用弹性模型，在桩土接触面间设立接触对。

Since the rotary plunger pump piston at each stroke can randomly rotate constantly change with the pump plunger cylinder contact surface, so that circular plunger gradually wear uniform or scaling at the same time, sand from the plunger and pump barrel between discharge and resolved accumulation Materials abrasion caused by wear and serious positioning rod release.

自旋转柱塞抽油泵可使柱塞在每一冲程中随机转动，不断地改变柱塞与泵筒的接触面，使柱塞圆周逐渐均匀磨损的同时将砂粒或结垢从柱塞与泵筒之间排出，解决了磨蚀材料聚集所引起的严重定位磨损及杆柱脱扣

Since the rotary plunger pump piston at each stroke can randomly rotate constantly change with the pump plunger cylinder contact surface, so that circular plunger gradually wear uniform or scaling at the same time, sand from the plunger and pump barrel between discharge and resolved accumulation Materials abrasion caused by wear and serious positioning rod release.

自旋转柱塞抽油泵可以使柱塞在每冲程中随机转一下，不停地转变柱塞与泵筒的接触面，使柱塞圆周逐渐匀称磨耗的同时将砂粒或结垢从柱塞与泵筒之间排出，解决了磨蚀材料聚集所导致的紧张定位磨耗及杆柱脱扣。

Based on the gear geometry of the double enveloping hourglass worm gearing, the tooth surface of the wheel, which is composed of the so-called the original and new contact surfaces, is derived.

基于齿轮几何形状的双包络环面蜗杆的齿面的车轮，后者是由所谓的原始的和新的接触面，导出。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
