双球面的

Took the different diameters double-row bearing slewing ring asexample, this dissertation studied the distribution of axial press ofthe rolling body under axial load and throw moment, the contact pressbetween two outer seat-rings which are connected to the main machinewith high strength screw bolts.

本文以双排异径球式回转支承为例，对球式回转支承在承受轴向载荷和倾翻力矩时的滚动体轴向正压力大小、分布及由高强度螺栓与主机连接的滚圈接触面的接触力进行了详细的理论推导和实际计算，说明在双排球式回转支承的结构静力分析过程中，可以将滚圈安装接触面的接触力简化为铅垂方向的均布载荷。

The people very are early realize CVT are facilitate driving, enhance the vehicles fuel oil efficient ideal installment, appears the bipyramid ball, the plate, the hooped column body from several dozens years ago and so on develops the leather belt transmission, but as a result of the rubbing surface friction coefficient and the components withstanding unit pressure limit, adds in the processing craft and the control difficult problem, cannot transmit compares the high efficiency, only limits uses in on the compact car.

人们很早就意识到CVT是方便驾驶、提高车辆燃油经济性的理想装置，由几十年前出现的双锥体球、盘、环柱体等发展到皮带传动，但由于摩擦面的摩擦系数及零件承受单位压力的限制，加之加工工艺和控制上的难题，不能传递较大功率，仅限用于微型汽车上。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
