The mathematic simulation software compiled by this paper has been used to simulate the basic characteristics of the main parts of the aircraft ac EPGS, include the permanent brushless dc generators , the exciters with rotating rectifiers, the brushless ac generators, the brushless dc generators, the inverters and the automatic voltage regulators .

运用本文建立的数字仿真软件对飞机交流电源系统的主要部件，包括永磁无刷直流发电机、旋转整流励磁系统、无刷交流和直流发电机、逆变器和调压器的基本特性进行了研究。

Fairings are the plastic covers that surround the frame of your pocket bike, and give it a "super bike" type of look.

整流罩的塑料外壳是围绕著帧您的跑车，并给它一个&超级自行车&式的外观。

Thus, the basic framework was of all-tubular construction with no refinements, such as fairings, appearing as semi-permanent fittings until the V4 machine, although this machine was by no means intended as the final design.

因此，基本框架是全管结构，如没有改进整流罩，为半永久性的配件出现，直到V4的机器，虽然这台机器而绝非是最终的设计意图。

The engine, running gear and wheels are carefully shielded by streamlined fairings to keep the rider clean and obviating the need for special clothing under normal weather conditions.

齿轮传动的发动机由流线型整流罩细心遮罩以保证驾乘者的清洁而无需在正常天气状况下穿专门的服装。

The results of simulation offer the relation between the parameters of generator and maximum fault current.

3在整流系统设计中，可根据短路电流的控制需要，设计和选择合适的同步电机参数，以确保故障保护装置的安全动作。

The DTC system with the rectifier using space vector modulation was studied.A novel input power factor closed-loop control method using hysterias controller was proposed in order to reduce torque ripple based on the analysis of torque ripple.

对整流环节采用空间矢量调制时的直接转矩控制系统进行了仿真研究，在分析转矩脉动的基础上给出了一种输入功率因数滞环比较的闭环控制方法。

Because of the difference of the power stage and the technique requirement, the required topologies of the rectifiers are also different.

对于不同功率等级和不同的技术要求，采用的整流拓扑结构往往是不一样的。

Another limitation of the vacuum tube rectifier was that the heater power supply often required special arrangements to insulate it from the high voltages of the rectifier circuit.

真空管整流器的另一个限制是加热器电源经常需要特别安排，以使它遭受高电压的整流电路的影响。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
