For the tuning, I have added an external powered DC motor, the rotor speed is measured with a hall probe and an oscilloscope.

为整，我有一个补充，外部供电的直流电动机，转子速度是衡量一个霍尔探针和示波器。

Without these phenomena, can disconnect the output side of the current transformer and DC side of the Hall Voltage Sensor current detection, reset after the operation to see if there were flow phenomenon.

如果没有这些现象，可以断开输出侧的电流互感器和直流侧的霍尔电流检测点，复位后运行，看是否出现过流现象。

After study the potential energy of the dc-SQUID, the Hamiltonian of the device is presented.

通过引入直流超导量子干涉器的相位势，给出系统的哈密顿量。

Second, Mr McCain should hammer away at the dangers of single-party rule in Washington, DC.

第二，麦凯恩应该不断强调华盛顿一党专政的危害。

Was the first to manufacture the Outdoor Swing Gates Indoor Swing Gates DC Sliding Gates Handspike Swing Gates Prison Swing Gates Solar Battery Tracker Solar Battery plank and intelligent remote controllers are available.

专门从事研发、生产、销售户外平开门机、室内平开门机、直流平移门机、推杆式开窗机、监舍门开门机、太阳跟踪器、太阳能电池板、远程遥感器等智能门控产品。

In addition to the traditional dc accuracy specifications such as linearity, full-scale and offset errors, the part is also specified for dynamic performance parameters including harmonic distortion and signal-to-noise ratio.

除线性度、满量程和失调误差等传统直流精度规格外，该器件的动态性能参数也做了详细规定，包括谐波失真和信噪比。

The power variation of the targeted harmonic signal and harmonic suppression ratio were calculated and evaluated. The theoretical caculations and simulated results suggest that power variation can be maintained within 1 dB with dc bias drift less than 5% and the harmonic suppression ratio is stable in the SSB RoF link.

理论计算和仿真结果表明，偏置漂移会使目标信号的功率抖动增大，但当偏置漂移量小于5％时，功率抖动小于1 dB，而谐波抑制比保持稳定；分析了与非理想光电调制器啁啾相关的有限消光比和双臂驱动不平衡度对RoF链路性能的影响，有限消光比会增加目标信号的功率抖动并降低谐波抑制比，而通过优化调制器的双臂驱动不平衡度可以提高单边带调制RoF链路性能。

The harmonic torque of a novel kind of brushless DC motor is studied in this paper.

本文对一种新型无刷直流电动机的谐波转矩进行了研究。
