To understand the hyperbolic motion of the probe and give necessary orbit information not only the discrete positions to both ground-base or satellite autonomy device, we studied the variation of hyperbolic orbit and gave the variation equations like that of elliptic orbit.

这段轨道相比其它段虽然很短，但却是实现最终探测目标的关键弧段。为了更好地了解探测器的在这一关键弧段的运行状态，给地面测控系统或是星上自主设备提供必要的轨道信息，而不仅仅是探测器在一些孤立点上的位置和速度，有必要对双曲线轨道及其变化特征进行研究，给出类似于椭圆轨道及其变化的一些基本规律。

Roundness tolerance of pitch diameter Roundness tolerance for a minimum of 345o circumferential arc of the pitch diameter shall not exceed .002 inch (0.051 mm) total, or one half the pitch diameter tolerance if the pitch diameter tolerance is less than .004 inch (0.102 mm); roundness tolerance of the remaining 15o maximum circumferential arc shall not exceed .004 inch (0.102) total, provided such tolerance does not result in excrescence on the thread flank.

圆度公差沥青直径圆容忍最低限度的345o圆周弧音高直径不得超过0.002英寸（ 0.051毫米）总，或一的一半，足球场直径公差，如果沥青直径公差小于0.004英寸（ 0.102毫米）；圆的耐受性，其余15o最大周弧不得超过0.004英寸（ 0.102 ），共计提供这样的宽容不会导致在excrescence对线程的侧翼。

With the new method, a simplified polygon can obtained following two steps, filleting the original polygon and transforming the filleted shape to a polygon.

这种方法先对原多边形进行弧化，然后将弧化后的模型还原为直线边界的多边形，就得到了简化的图形。

That is vary important for finite element analysis of temperature field on the gear tooth surface.

完成了弧齿锥齿轮三维准稳态温度场有限元分析。为弧齿锥齿轮的摩擦学特性分析和胶合承载能力计算提供了必要的基础。

Based on TPAW, finite element calculation of temperature field in keyhole plasma arc welding is conducted, and.

在此基础上，对小孔等离子弧焊接热场进行了有限元计算，分析了引弧后熔池及周围温度场的瞬时演变过程。

Combining the discusses of flysch prototype basin which is called Baryan Har basin, we know that the Baryan Har basin is a large-scale back-arc basin resulted from intensively depression of back-arc area. It formed after tectonic setting transforms to pressure from extension and is at the same time as development of Yidun island arc.

同时，结合对沉积复理石的原型盆地——巴颜喀拉海盆性质的讨论，以为巴颜喀拉海盆是在松潘-阿坝地区构造背景由拉张转化为积存之后，在义敦岛弧发育的同时，弧后区强烈坳陷形成的大型弧后盆地。

Besides, the stress state of oil pipiline suffered from the frost heaving hazard was predicted by finite element numercial simulation. When the design pressure is 10 MPa, the pipe wall thickness should be no less than 14.2mm.
