In order to deliver an effective strike shot, a stroker must be able to position his hand under the ball for maximum revolutions.

为了打出较多的全倒，stoker必须将手指保持於球的下方来获取最高的转速。

This paper analyses and presents the design method of small discharge low specific speed submersible sewage pump.

探讨和提出了小流量低比转速潜水排污泵的设计方法，给出了 QW10 - 2 0 - 1.5型泵的设计实例和试验结果。

The influences of the nonlinear clearance-excitation fluid force of turborotor on the dynamic behaviors of rotor's axial rub-impact are insignificant. The only effect is the appearances, in the axial response, of the higher order superharmonic components of even-time working frequency at low rotating speeds.

分析表明，非线性涡轮叶尖间隙流体激励力对转子轴向碰摩的非线性特性影响不很明显，只是在低转速时轴向振动碰摩响应中会出现更高阶的偶数倍频的超谐波成分。

A well-adjusted engine will have a stable idle and will not surge up and down after the throttle is closed.

一个完美的调整引擎将有稳定的怠速，收油门转速会上上下下都是不正确的。

It can fulfill automatic control on swash plate of

它通过对发动机转速信号、大气总温信号的处理，解算出斜板的理论位置，与斜板的位置传感器信号进行比较，其差值作为控制信号经放大后控制电液伺服阀带动作动筒，使斜板向减小差值的方向运动，从而实现对飞机进气道斜板的自动控制。在这一系统中

Cleaning system uses a hydraulic transmission device, so that roll between the sweep and the sweep speed set with a more rational norms, efficiency doubled.

清扫系统采用液压传动装置，从而使滚扫与盘扫之间的转速配合更加合理规范，工作效率倍增。

Somewhere in-between, the engine would switch from one cam to the other.

在此之间的任何转速，发动机都能够在这两个凸轮之间相互转换。

Thirdly, theoretical stress analysis of the drum is made, and a finite element stress and model analysis of LW500×1200 basket is made too. The result shows that the drum intension satisfied the demand, and sympathetic vibration will not happen in normal rotate speed. Comparing the real situation, the decanter centrifuge of this type meets the safe demand.

再次，介绍了高速离心机转鼓的理论强度计算公式，并应用有限元分析软件ANSYS对LW500 1200离心机转鼓做了有限元强度分析和振动模态分析，结果表明离心机转鼓满足强度要求，而且在正常转速范围内不会发生共振现象，对照该型号离心机实际现场应用的情况，本文所研究的钻井液离心机确实能够满足工作安全要求。

Secondly, the cutter of the machine was studied from reducing vibration, emphasis on knives array, homeostasis. To apply "ANSYS"method, At the same time, it was known that inherent frequency of the main axis was so far higher than vibratory frequency, and the machine main axis'rotational speed won't cause sympathetic vibration.

其次，本文从减少振动入手对9LRZ-80型秸秆揉切机的关键部件切碎器进行分析，着重对动刀片的排列、动平衡等进行分析研究，并通过有限元分析，得到切碎器主轴固有频率远远大于机器振动频率，机具的转速不会造成共振的危害。

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。
