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。

Firstly, the developing principles of the cylindrical internal helical gear are proposed through analyzing the movement and geometry requirements, which provides continuous contact between the mating gear surfaces. The tooth surface of the internal helical gear in the new gearing can be imagined as being generated by the normal section of the conjugated surface of the ball-tooth, moving along the radial projection of helix line of the tooth-root circle. Also, the proposed surface can be approximate tangent to the conjugated surface of the ball-tooth along a spacial curve.

首先，通过分析保证行星轮作螺环运动时与内斜齿轮实现连续啮合传动的运动和几何条件，提出了圆柱内斜齿轮齿面的两种形成原理：即由球齿运动包络曲面的法截面沿其齿根圆螺旋线在径向的投影进行拓展所形成的内齿面，以及与球齿运动包络曲面呈近似相切接触的等螺距齿面构成的内齿面。

As the season trudges along, every fifth day we forget all about Hughes' and Kennedy's troubles and watch a potential milestone season unravel for Wang. We hold our breath with every pitch thrown hoping that the problematic fingernail does not flare up and impede on his march to October. Last night you could hear the gasps from the raucous crowd when in the fifth inning, Wang summoned Jose Molina to the mound after a pitch and was seen flicking his right thumb. Manager Joe Girardi and Head Trainer Gene Monahan immediately jogged to the mound, hoping their worst fears were not realized. At that point you could immediately feel the sense of urgency in the organization. This was their gem, their only bridge between now and championship number 27. 9 M# u7 Y s# W O

随著这个令人心情沉重的球季持续进行著，每5天我们就可以忘掉所有关於休斯和甘乃迪的困扰，并且看到王小民开创可能是一个生涯里程碑的球季，在他投出每一球时，我们屏气敛息希望他那常搞飞机的指甲别出状况，而妨碍到他进军十月份的比赛，昨晚第五局王小民投出一球之后，招手要莫里那上投手丘，并且轻轻活动他的右拇指时，你可以听到喧闹的观众中传来阵阵的喘气声，总教练吉拉帝和主任防护员Gene Monahan马上跑上投手丘，希望他们最害怕的事情千万别发生，在那个时候你可以立即感受到球团里面的焦急感，这是他们的瑰宝，他们通往第27座世界冠军头衔的唯一桥梁。2 V# T6 h+ 9 o$ P' J

The so-called cutter location point, the flat end mill tool axis refers to the point of intersection with the bottom tool; for ball-end milling is the ball part of the core; for tools is the tip; the drill is the drill point; for wire electrode cutting machine, it means that the axis line of the electrode surface and the focus of parts.

所谓刀位点，对于平底立铣刀是指刀具轴线与刀具底面的交点；对于球头铣刀是指球头部分的球心；对于车刀是指刀尖；对于钻头是指钻尖；对于线电极切割机床，则是指线电极轴心与零件面的焦点。

For example, there is such a time: When the ball between the goal posts from entering or crossing the space above, no matter how high, if not by hand throw, hit, transport into and are considered a goal to win.

比如当时有这样一条：当球从球门柱之间进入或在上面的空间越过，不论高度如何，只要不是被手扔、击、运进去的，都算赢一球。

Mercator is the type of projection you see used on Live maps and Google maps, but as many often mistakenly thinks, they do NOT use WGS84 for the projected map, although WGS84 is used when you directly input longitude/latitude values using their API.

Live Map和Google Map都使用墨卡托投影，但并不像人们认为的那样他们使用WGS84基准面，虽然你在他们的API中输入的值是WGS84下的值。【译注：原因是WGS84基准面是基于椭球面的，而LiveMap和GoogleMap使用的是球面。另外，YahooMap使用的是等距圆柱投影。

After the linear pointing correction, the surveying region is divided into spherical Delaunay triangulations, and the whole smooth pointing correction surface is produced by using the high-accuracy generalized extended interpolation approximation method.

提出了一种新的基于广义延拓插值的射电望远镜指向误差修正模型，在线性修正模型的基础上对观测域进行球面的Delaunay三角剖分，利用高精度的广义延拓插值逼近方法生成不分项的整体分布曲面。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.
