By setting two perspective cameras at the first molars of the upper jaw and using the OpenGL selection mode,the real-time collision detection with high efficiency between lower and upper jaws can be realized as the lower jaw rotates around the axis of the articulator.

该方法通过在上颌左右第一磨牙近中舌尖处建立透视视景体，利用O penGL的选择模式，可以实时地检测下颌模型绕牙合架转动轴线旋转过程中与上颌模型碰撞对位情况，效率很高。

Such children were not caused by the throat-ming weakness caused by laryngeal cartilage, but when inspiratory arytenoid cartilage move downward rotation, the relaxation of their organizations to the sound in front of the Ministry of processes, blocking occurs supraglottic laryngeal ming.

这种患儿之喉鸣并非因喉软骨软弱所致，而是当吸气时杓状软骨向前向下转动，其上的松弛组织向声门前部突起，阻塞声门而发生喉鸣。

This was the first water-powered astronomical instrument in the world.

这是世界上第一台用水力转动的天文仪器。

To live in Beijing is a little like being in the center of a wheel turning at full speed.

Construction and Principle: The unit consist of frame,rotate mechanism, porp mechanism and knift mechanism.it's principle is that select the tire bead as a prop point and place it on porp mechanism,then adjust it to tightly.start the machine in low speed by slow down transmission part;knift is setted on the machinery panel and it can be forward and back at one's ease.

该机由机架、转动机构、支撑架、刀具机构等组成。其基本原理为选择轮胎内圈为支撑点，将内圈制于支撑架。经支撑架的调节机构将轮胎牢固地撑紧于支撑架；通过减速传动机构获得低速运转；切割刀具安装于机械台面板，可根据需要任意进退刀。

How you settled your head athwart my hips and gently turn'd over upon me

你如何将你的头，压住我的大腿，柔和地在我身上转动。
