查询词典 DC

The mechanism is composed of two ball screws, U-type linear rails, linear bearings and flexible couplings. The permanent magnetic direct current motors are used as actuators. The rotary encoder is used to measure the angular position of the DC motor. The digital controller is implemented on the personal computer and a motion control card (EPCIO-6000). The objective of this thesis is to realize precise positioning control using a real-time motion control system on an X-Y table.

机械结构包括有滚珠导螺杆、U型线性滑轨组、线性轴承及可挠性连轴器等；致动器是采用永磁式直流马达(permanent magnetic direct current motor)；感测器是使用光学式旋转型编码器来量测马达旋转的角度；控制器则是以个人电脑为控制核心，搭配运动控制轴卡(EPCIO-6000)所组成。

The paper specially gives a particular description of the V-A characteristic of 20kW xenon short arc lamp ,the performance test of trigger,and the electrical performance and stability of switching DC power supply.

文章介绍了 KM6太阳模拟器氙灯单元试验的全部过程，对短弧氙灯的伏安特性进行了研究。

Based on the analysis of three-dimensional power conductor for DC arc furnace, the electric arc deflection model was set up and the control system of the arc direction was configured. According to the bus bar distribution at the bottom electrodes cooled by water, the arc direction control principle and its configuration were described, The simulation results show that the control system can restrain the electric arc deflection and control the arc direction.

在分析直流电弧炉三维导体布置的基础上，建立了直流电弧的偏工以此作为电弧位置控制的依据，针对水冷钢棒式底电极型的直流电弧炉，阐述了其电弧位置控制的原理和系统组成，并进行了仿真研究，结果表明控制系统可以有效地纠正电弧的偏向总是并可控设定点自由控制电弧以位置。
