It was crowned with a rotating armillary sphere that was hydraulic-powered (ie by waterwheel and clepsydra clock), yet it incorporated an escapement mechanism two hundred years before they were found in clockworks of Europe, and featured the first known endless power-transmitting chain drive.

这是圆满旋转浑仪是液压动力，但它纳入一个擒纵机制二百年才找到他们，在clockworks欧洲，和精选的第一个已知的无休止的权力转递链驾驶。

But to the French, who fought hard-won battles against authoritarian clericalism, it stems from a secular wish to keep religion in the private sphere.

但是对于法国人来说，他们在对抗专制的教权主义中取得了来之不易的胜利，将宗教活动控制在私人区域内起源于一个非宗教化的愿望。

The results show that the most close-packed surface (111) orientation of FCC metals which have the lowest surface energies will grow preferentially, the surface energies for the all lattice surfaces increase linearly with increasing including angle between the surfaces and (111), which are consistent with the experimental and the linear muffin-tin-orbital-atomic-sphere-approximation results.

结果表明，FCC金属的密排面（111）的表面能最小，则该晶粒取向优先生长，与实验结果和第一原理的LMTO－ASA计算结果一致；各个晶面的表面能均随着其它晶面与（111）晶面的夹角的增长而呈线性增长关系，因此利用（111）面可推导出其他各面的表面能量。

For genus zero closed surfaces,the parameter domain is sphere,so the cutting of the surface meshes in the parametrization process is avoided.
