研究了在SrCl2-SrF2-BaF2的电解质体系中熔盐电解法制备高浓度Al-Sr合金，采用连续脉冲-计算机法测定电解过程的反电动势并且对反电动势和电流效率的影响因素进行了详细的研究。

In this paper, the change of back electromotive force current with the different PWM modes are analyzed in detail on the base of BLDCM model. According to theory and experiment ,ON-PWM type restrains the peak value of back electromotive force current and brings the lest effect to the motor control system.

基于无刷直流电动机的数学模型，分析比较了不同PWM调制方式下反电势电流的变化规律，并通过理论推导和仿真实验证明了当电机系统采用ON-PWM调制方式时，能有效地抑制反电势电流的峰值且对电机控制系统造成的影响最小。

In addition, since the back electromotive force occurring in an inductance element is cleared to zero during a half wavelength of period of the cosine wave, speed electromotive force can be measured by immediate shifting from a setting period to a measuring period.

另外，由于在余弦波的周期的半波长期间，使在电感元件中产生的反电动势VL清零，通过立即从设置周期转移到测量周期，能测量速率电动势。

The balanced labor force price is a category of complete free market, and is an outcome of complete competition between labor force supply and demand.

劳动力均衡价格是完全自由市场经济的范畴，是劳动力供给与劳动力需求完全自由竞争的产物。
