小齿轮或者是蜗杆有数个牙口，通常是1个到4个。当他们被完整的缠绕在节圆柱时，它们就是所谓的轴轮。

Based on the kinematic and dynamic analyses of the gear honing model where a worm-shaped hone is used, a theoretica.l study on the mechanical mechanism of the process is performed.. Looked upon.from, its principle of computation, the analysis of gearing is transformed into furthermore a problem of non-linear programming.

本文通过蜗杆珩轮珩齿模型的啮合运动、动力分析，探讨了珩齿的力学机理，并从计算原理上把啮合运动分析问题转化为非线性规划问题，在此基础上提出了计算机辅助珩齿机理分析的算法。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
