When a rotating voltage vector is injected to the motor at standstill, there is a microinching when the voltage phase is line to the direct axis of the motor. Then the current will decrease due to the back electromotive force. The initial mover position is identified by this change.

电压相位和电机直轴重合时，产生的电磁推力超过负载阻力，电机有一微动，由于反电势的作用电流就会降低，通过检测电流矢量的变化来估计动子的初始位置。

By means of image theory and potential superposition principle,this paper presents the analytic solution of water cresting height and lateral distance from wellbore under steady flow,and optimizes the optimum wellbore placement.

本文以物理化学理论为指导，实验为基础，较详细地介绍了矿料遇水后，表面电荷的起因、表面电荷的性质和ζ电势的测定，从而说明沥青与矿料间的相互作用机

By use of the relationships between the hermite polynomial and the laguerre polynomial, the eigenequations of one-dimensional harmonic oscillator and hydrogen atom are conversed into the same equations in form.

同时本文利用SU(1，1)代数将二维、三维情况下的谐振子同加了反平方势的氢原子分别表示成具有相同形式的两算符下的本征值方程，从而得出

In a group, you detect well that those men of rank and wealth have an experience of ill-got fortune; those men of high position all are obsequious experts.

在一个团体中，那些有钱有势的人，你清楚地了解，他们那些横财至使他们致富的经历。自于那些位居高位者，又有那一个不是吹牛拍马屁的专家。

Given the recent change of control in Congress, popularity of measures like increasing the minimum wage, and efforts by California' governor to offer universal health care, these guys don't need their own personal weathermen to know which way the wind blows.

这群有钱有势的人可能是通过表达对中产阶级的挣扎的同情，进而逃避没收性税务政策。

To solve the velocity potential,we used an integro-differential equation.
