The features to evaluate the tooth contact quality such as the location of the contact point on the tooth surface, clearance between the meshing tooth surfaces, curve of the transmission error and the path of the contact point are investigated. The accurate geometric representation with non-uniform rational B spline of the worm and the wheel tooth surface is presented then the corresponding program is developed.

Plumber-Neck The plumber-neck is characterized by a horizontal bend just below where the end of the shaft and the hosel meet. This design, which generally provides a medium amount of offset, does a great job of keeping the hands ahead of the clubhead through impact. This tends to make the putter more forgiving and easier to use, which is the reason it's so popular.

Plumber-Neck：该特点在於在杆身末端与杆颈连接的地方有个水平转折处，这样的设计提供了中度的OFFSET，这样的设计能让手在击球时永远在杆头前面，这会让推杆有更大的容许误差量并更容易去使用她，这也就是为何这种杆颈造型成为受欢迎的原因。

Flare-Tip The flare-tip is typically a "shaft-over" hosel, meaning the shaft covers the top of the hosel where the two connect.

Flare-Tip：该特点在於杆颈插在杆身内，也就是说杆颈的最上端是在杆身末端内。

This method adopts the variable step length scheme to evaluate at the connection point, and adopts the implicit difference scheme to evaluate in the same rod.

In order to implement the fault diagnosis of Chongqing light-rail's screws,a new method of screw fault diagnosis based on Support Vector Data Description is proposed,which can found one-class classifier with normal screw samples only and doesn't need feature extracting.The method solves the difficult problem of lacking fault screw samples.

为了实现对重庆市轻轨轨道梁锚固螺杆的故障检测，提出了一种基于支持向量数据描述的锚固螺杆故障诊断方法，该方法只需要正常螺杆样本，且不需要对原始数据进行特征提取，就可以建立单值分类器，解决了缺少故障螺杆样本的难题。

The theoretical and computational results show that an important reason resulting in eccentric wear of the inner cylinder and the pumping rod lies in the nonuniformity of the stress distribution on the outwall of the inner cylinder which yields excentralization effect of the pumping rod when swabbing fluid flows in eccentric annuli with the pumping rod moving axially in a well.

在实验上，通过不同重量百分比浓度的HPAM水溶液在内管做轴向往复运动的偏心环空中非定常流实验，把由理论公式算得的时间平均流量与实验中测得的时间平均流量做了比较，验证了本文数值计算幂律流体在内管做轴向往复运动的偏心环空中非定常流方法的正确性；上述的理论与计算表明，抽油机井杆管偏磨的一个重要原因是，在聚驱工况下，抽汲液体在抽油杆做轴向运动的井筒中流动时，抽汲液体作用在抽油杆外壁上的压力分布的不均匀性所引起的抽油杆在井筒中的偏心效应。

The basic principle of optimum structural design of special sucker rod pump was put forward according to real oil well conditions.
