Thus the author established a unified theorem of the shaping of tooth flank, which can be applied to both Free-form and traditional cradle machine tools, unified the theories of both circular-arc and extended epicycloid bevel gears.

为此，作者建立了齿面成形的统一理论，它适合于Free-form型和传统摇台类两种机床类型，并将弧齿锥齿轮和延伸外摆线锥齿轮统一在了一起。

Simulated ray of the beamline has been built to check and measure sagittal focusing facula.

建立了光束线模拟光路，可以实现对弧矢聚焦效果的检测。

Although detail removal can be carried out in the process of filleting operation and its inverse operation, entities such as vertices, edges and faces with which the simplification operations handle directly lack engineering features, so that the simplification fails to satisfy all the needs of engineering applications.

通过"弧化-还原"，虽然可以实现几何形体的简化，但是这种几何简化是在点、线和面低层次的几何元素上进行的，几何简化的工程意义不明显，难以保证实际应用中的分析几何模型简化的有效性。

Performance checking and measuring of the first sagittal focusing monochromator in internal had been successfully achieved out of beamline,ch...

利用该方法，完成了我国第一台弧矢聚焦双晶单色器的离线检测，检测结果达到了理论设计指标，表明了测试方法的有效性。

Therefore, first of all, a manipulator-level off-line programming system has been developed.

因此，本文首先进行了机器人弧焊执行级离线编程系统的开发。

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。
