最大转速

As one of the most often used mountings, the altazimuth mounting satellite tracker has a blind area near the zenith because of the very high azimuth angular velocity, as a result, discontinuous observing data are caused. As for those fast flying satellites, this kind of blind area is very significant because it causes difficulties in precisely determining the satellites' orbits.

作为最常用的一种机架，采用地平式机架的人卫跟踪仪在观测天顶附近区域的目标时，由于方位转速过大而不能连续观测，存在一个固有的天顶盲区，特别是对飞行速度较快的近地卫星，这个盲区的影响是相当大的。

This engine benefits from variable valve A high-performance chassis for saloon-style driving sensations timing and camshaft variator which permits two types of use: one calibration for idling or when running partially loaded at mid and high revs for maximum power, and a second calibration which permits a bigger overlap between the intake and exhaust strokes for a torque gain of between 5 and 10Nm.

从可变气门的高底盘的轿车性能风格的驾驶感觉，时间和凸轮轴变速器的许可证或空转运行时有部分中的最大功率和高转速装两种用途：1校准这台发动机的好处，和第二个校准它允许更大之间的进排气重叠杆为5至10纳米扭矩增益。

In this dissertation, the degreased rice bran extrusion processing had been studied by single factor and the multi-factors experiments in order to obtain the maximum SDF conversion rate .

以脱脂米糠为原料，运用挤压加工技术，以较大的SDF转化率和最好的IDF吸水力和膨胀力作为指标，进行了正交试验研究，确定了最优工艺参数组合：物料含水量25％，挤压温度140℃、螺杆转速 150r／min。

The first control strategy has the disadvantages such as a large amount of computations, inherent pull-out torque, difficulties in realizing the adaptive control and so forth. For the rotor flux-oriented control, changing of load or the rotor speed will result in increased or decreased torque winding currents, which will change the magnetic field distribution in the air gap. Assumption that magnetic field is approximately equal to that generated by torque windings will affect the levitation performances.

分析表明：气隙磁场定向控制中存在最大转矩限制、非线性机械特性，难以实现自适应控制等问题；对转子磁场定向控制而言，当负载或转速变化时，由于转矩控制绕组转矩电流变化将导致气隙磁场发生改变，如果仍以转子磁场近似替代气隙磁场作为悬浮依据，必然影响到悬浮控制性能。

Secondly, the structure and operating principle of imitation of the wind turbine based on DC motor were formulated and the control strategies were introduced.

第三，用Ansoft仿真软件建立了风力机模拟和SRG系统的仿真模型，分别对风力机特性的直流电动机模拟系统和SRG开环系统、电压闭环系统的建压过程及变负载、变转速动态过程、SRG风力发电系统最大风能追踪控制方案进行仿真分析，结果与理论吻合较好。

The determination of speed ratio gear box, it is necessary to take into account the different speed pump to meet the test requirements, but also consider the maximum torque of the engine near the work.

齿轮箱速比的确定，既要考虑满足不同转速泵的试验要求，又要考虑让发动机在最大扭矩点附近工作。

An additional hydraulic pump is responsible for this transferral: if a pre-determined torque value for the wheels is exceed ed, the pressure is rerouted via a magnetic valve to a faster-turning wheel, thereby braking it.

新增加的一个液压泵负责完成这项扭矩传输任务：如果车轮超出了一个预设的扭矩最大值，制动压力就通过一个磁阀传输到转速较快的车轮，然后给它施加制动力。

The goal is to have an engine that makes lots of torque throughout its entire rev range.

目标是在发动机的整个转速区间内都能发出最大的扭矩。
