The quality of this transition is best visualized by a straight line drawn between two circles: the line's only point of contact with each circle is tangential.
用最明显的图形来描述这个过渡的特性就是：当在两个圆之间绘制一条直线，直线与每个圆只有一个交点时，那么这条线就是两个圆的切线。
In small tooth difference of inner meshed transmission, there were a few pairs of tooth faces which were apart from each other for a small gap beside the contact point generated by two meshed teeth.
在少齿差内啮合传动中，存在多对接近啮合的小间隙齿面于理论啮合点左右，轮齿受力产生的微小变形使得某些对齿面相互接触进入啮合状态。
The two elements of a lower pair have theoretical surface contact with one another, while the two elements of a higher pair have theoretical point or line contact (if we disregard deflections).
这两个因素中的低副是两个理论表面之间的接触，而这两个因素中的高副是理论的点或线接触(如果我们忽视了挠度)。
Compared to the new wheel tread, the worn tread is easy to form two-point contact nearby the depression area of the nominal diameter position of wheel tread.
与新用车轮踏面相比，测试得到的磨耗后车轮踏面在其名义直径位置凹陷区域附近容易形成踏面两点接触。
In the paper, two complemental formulae are derived for using the relations of relative motion of the contact point to analyse the motion of plane mechanism with high-pair.
