That is to say, during the starting process of induction motor, hold-off angle of current has gradually decreased from initial value to zero. The method can always make the displacement angle less than thyristor's firing angle. So the voltage of the induction motor won't oscillate. Therefore, the oscillation of current, electromagnetic and speed can be eliminated during the soft-starting process of induction motor. This paper verifies the correctness of the method by simulation at first.

根据上述原因，本文提出了采用关断角控制的新型控制策略，这种控制策略是使电动机在起动过程中的电流关断角由某一初始值逐渐减小到零，利用该方法可以使感应电动机起动过程中的续流角始终小于晶闸管的触发角，这样续流角的变化就不会引起电动机端电压的振荡，因而就从根本上消除了感应电动机软起动过程中的振荡现象。

该公司直接在插鞘处标明反弹角的程度，一个黄点表示低反弹角，两个黄点为标准反弹角，另外数字则表示反弹角度。

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。
