At present, the location of the anti-lopsided wear centralizer used in fields is mainly based on the deviation angle. In fact, lopsided wear may be caused by the change of azimuth angle or by the vertical well section and hold angle section during the working of the bucket rod.

目前油田矿场主要根据井斜角来确定防偏磨扶正器下入位置，实际上方位角变化也能导致偏磨，抽油杆杆柱在运动过程中直井段和稳斜段也会产生偏磨。

According to the results of this study, the ultimate strength of pin-bone interface increased as the moment arm decreased and torque increased. When the pin-bone angle approached 90°, the ultimate strength was the largest and as the angle decreased, the ultimate strength decreased. There was no significant difference between rigidity and torque, but rigidity decreased as the skull-bone angle decreased.

结果发现钉骨界面的极限强度在头圈距离颅骨的力臂短时较高，且随著所用扭力的增加而增加，当头钉与头骨表面的夹角成垂直时最强，随著夹角越趋锐角而渐减，钉骨界面的刚性与扭力并无明显关系但与夹角有关，夹角垂直时刚性最高，而后随著夹角渐趋锐角而递减。

In order to real-timely and accurately measure thread parameters such as thread angle(tooth-type half-angle),screw-pitch,lead,thread height,major diameter,minor diameter,pitch diameter,helix angle etc,and enhance the measuring accuracy,a non-contact thread parameter measuring system based on an array CCD was designed and achieved.

To further study this problem, the optical axis is rotated by an arbitrary angle. A striking phenomenon is discovered that the Brewster angle is always equal to the rotation angle. This is because the waves in the direction perpendicular to the optical axis become evanescent since the permittivity is positive while the permeability is negative in this direction.

然后进一步的研究了主轴不垂直于界面的情况，发现主轴转动的角度恰好等于此时的Brewster角，这是因为此时垂直于主轴的方向上介电常数为正磁导率为负，只有倏逝波而没有可传播的波存在，因此反射系数为0。
