转速

The high speed centrifugal pump, the delivery of materials by the strong impact, as well as the role of centrifugal force, the centrifugal pump the mixture in the transportation components often have different physical phenomena, so that the quality of the finished product.

而离心泵的转速很高，被输送物料受到强力的撞击以及离心力的作用，所以离心泵在输送混合物时经常产生物质成份不一的现象，使成品的质量下降。

And another use of FPGA is that provide DSP original data. DSP is used as digital filters used by sampling at the foreside and at the export correspondingly.The original data used by DSP is taken from the first adder in the circle. After the DSPs disposal,the output data are sent to guidance system.

总的说来，PGGA主要实现整个系统的时序控制和闭环回路，以及为DSP提供原始滤波数据；而DSP主要的工作是从PGGA那里取来第一个加法器输出的数据作为原始数据，再对数据进行滤波处理，最后的处理结果作为转速的信息送给捷联惯导系统。

On the basis of this analysis, author puts forward that the amplitude difference and the deflecting 90°phase differences between two standing waves are important reasons to cause unstable rotation of an ATWUM.

通过以上理论分析发现，在弹性体中形成行波的两个驻波波幅上的差异及其之间相位差偏离90°，是造成ATWUM输出转速不稳的一个重要原因。

"If the engine is turned over too slowly, the unavoidable small leaks past the piston rings and also through the intake and exhaust valves of four-cycle engines will permit a substantial part of the fuel-air mixture to escape during the compression stroke."

如果发动机转速太慢，四行程发动机的活塞环和进排气门就不可避免地有泄漏现象，这会使大量的可燃混合气在压缩行程期间泄漏掉。

As engine rpm increases,there is less time for each step of the four-stroke cycle.

当引擎转速增加，四冲程循环每一步的时间变得越短。

Incorporated with the proposed system, the performance of four-stroke engines at different speeds and loads will be significantly increased.

藉着使用本文提出的系统，四冲程引擎在同负载和同转速下的性能将可大大提高。

Based on rubbing model of a two-disk rotor-stator system with consideration of both rotor and stator dynamics,a numerical integration program is applied to numerical simulation and analysis of the nonlinear dynamics of this system,such as bifurcation,Poincare section map,trajectory of axes,phase trajectory,frequency spectrum diagram and time response.

基于一新型径向-轴向复合碰摩双盘转子-机匣力学模型，利用数值积分和Poincare映射方法，对转子-机匣系统由于径向-轴向碰摩故障导致的非线性动力学行为进行了数值仿真研究，给出了系统响应随转速和偏心量变化的分岔图和一些典型的Poincare截面图、相轨图、轴心轨迹、幅值谱图和时域响应等。

In the second test, the frequency response function is measured and the primary natural frequency has been obtained.

前者研究了不同转速下行星齿轮动态响应的频谱特性，后者则给出了行星齿轮传动的固有频率。

In this system,the VVVF(variable voltage variable frequency) control method based on magnetic flux trajectory is applied.In the system,it is the target for the magnetic flux linkage polygon to be greatly approximate to the ideal magnetic flux circle.Considering such limitations as the low speed torque ripple,high speed real time and the working frequency of switching element,through the subsection synchronization control method by applying different numbers of magnetic flux linkage polygon for different frequency range,the perfect precision specifications for speed can be obtained.

系统采用基于磁通轨迹法的他控式变频调速方案，以磁链多边形尽量逼近理想磁通圆为目标，并考虑低速转矩脉动、高速实时性和开关元件的工作频率限制等约束条件，通过采用分段同步控制方式，在不同的频段采用不同的磁链多边形边数，使系统获得了优异的转速精度指标。

Parameter study was performed on the system design parameters such as friction-induced damping, friction coefficient, brake force and rotor rotational velocity.

并进一步分析了系统参数因素如摩擦系数、摩擦阻尼、制动力和转速等对制动尖叫倾向性的影响。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。

Designed by French fashion house Herm è s, this elegant uniform was manufactured in our home, Hong Kong, and was the first without a hat.

由著名品牌 Herm è s 设计，这件高贵的制服是香港本土制造，是我们第一套不配帽子的制服。
