The rolling tests prove that this setup model can control precisely the displacement of the lapped area in the tooth surface and keep the even backlash.

利用轮齿接触分析与齿轮啮合原理，建立了齿面均匀研磨与定点研磨控制的几何运动模型，经滚检检验，该模型能对齿面研磨位置与侧隙进行较准确的控制。

Likewise, primary care doctors are seeing similar phenomena and increasingly there are organizations such as Physician Care Direct and the American Academy of Private Physicians which are setup to transition a primary care practice into a model that can be described as two parts Marcus Welby, one part Steve Jobs.
