Under OHCI and UHCI, it was the job of the BIOS or USB controller to 'remember' the enumeration data for each USB device attached when the system entered a different power management state.

在UHCI 和 OHCI。在UHCI 和 OHCI标准下，当系统进入了和当前不同的电源管理状态的时候，每个连接到系统上的USB设备的基本数据是由BIOS或者USB控制器负责保存的。

But, without infringing on the ordinary power of the bishops, the pope, as head of the episcopate, possesses in himself the same powers as the episcopate united with him.

但是，如果没有侵犯普通电源的主教表示，教宗担任主教，拥有在自己相同的权力，因为美国主教与他的。

In addition, with reliable power supply and complete lightning protection measures, the power system in the building is still not the most safe. A good equipotential connection is another important protection measure for power reliability.

另外，有了可靠的供电电源和全面的防雷措施，大楼内的用电还不是最安全的，良好的等电位连接是增加用电可靠性的又一重要保护措施。

First, this article introduced the status of the electromagnetic launch technology in general. Then, the author further introduced a new principle of coil launch technology and its inductance in the equivalent circuit which are based on the principles of linear motor. It is a more comprehensive thought in the study. Third, in the building of the power supply system, the most important things are the trigger control loop structures, the gap switch debugging, the measurement of the impact current, and electromagnetic interference protection. Finally, I introduced the experiment, the simulation analysis of some questions in the experiment. The most important thing is the analysis of the equivalent circuit of the stator windings. And the author build a simulation model based on it.

This paper describes a feasible calibration method, its basic principle for calibrating is: A certain function relationship is existed in equivalent inductance L of coil and the distance x between the object to be measured and the sensor coil, the measurements can be conducted with this function relationship by using frequency modulation. The calibrating system consists of measuring electric circuit, high stable voltage power supply, digital frequency meter, the conductor to be measured and the calibrated displacement sensor.

文中叙述了一种较为可行的标定方法，其标定的基本原理为：线圈的等效电感L和被测物体与传感器线圈的距离x存在一定的函数关系，利用这种函数关系用调频法进行测量，标定系统由测量电路、高稳定度稳压电源、数字频率计、被测导体及被校位移传感器组成。
