An upright piano includes a fall-board (12) hinged to a upper sill (10f) and connected through a pair of flexible coupling (13) to side arms (10b), and each of the flexible couplings has a rotary damper (13b) embedded in the side arm and an Oldham's coupling (13a/ 13c/ 13q) connected between the fall-board and the rotary damper so that the Oldham's couplings take up misalignment between the rotational axis (AX1) of the fall-board and the rotational axes (AX2) of the rotary dampers.

The emulation result shows that the error of polarizer rotation angle almost does not influence nonlinearity when elliptic polarization of laser beams exists; when the error of rotation angle of polarizing beam splitter exists, the second-harmonic nonlinearity caused by the error of polarizer rotation angle will not increase, but the first-harmonic nonlinearity will increase greatly.

仿真结果表明，当存在激光束椭圆偏振时，检偏器旋转误差对非线性误差的影响很小；当存在偏振分光镜旋转误差时，检偏器旋转误差引起的非线性误差不增加二次谐波分量，但增大了非线性误差一次谐波分量，严重影响非线性误差的大小，当偏振分光镜旋转误差为3°时，检偏器旋转误差从0°增加到5°，非线性误差从0.14 nm增大到0.97 nm。

The real tangential velocity fluctuation indicated that there existed an instability of swirling flow in the cyclone.This instability resulted in the rotation center of the swirling flow deviating from the geometric center of the cyclone,which produced the quasi-periodic oscillation of swirling flow and gave the real tangential velocity fluctuation.

瞬时切向速度的变化反映了旋风分离器内旋转流的不稳定性，这种不稳定性导致了旋风分离器内旋转流的旋转中心与几何中心不重合，旋转中心围绕着几何中心摆动，由此造成了瞬时切向速度随时间的类周期的波动变化。

The particles with heavy specific gravity are discharged from the underflow mouth and those with light specific gravity are discharged through the overflow pipe and thus it realizes the separation for heavy and light particles.

流体自旋流器上端给入并在旋流器内形成强制旋转流，旋转流将颗粒按粒度和比重分为内外环层，当矿浆流动至锥体部分时，由于锥体的突然变向，阻力增大，颗粒群向下运动的趋势减缓，并在此形成旋转悬浮层，随着离心力场的减弱，重力作用越来越明显，由按粒度和比重分成的内外两层逐渐转化为按比重分选的上下两层，比重大的颗粒通过底流口排出，比重小的颗粒则通过溢流管排出，从而实现轻重颗粒间的分离。

I'm strongly against the death penalty — it's an eye for an eye.

我不赞成死刑——这是以牙还牙的报复行为。

And to get you the support you need, we're enlisting all elements of our national power: our diplomacy and development, our economic might and our moral suasion, so that you and the rest of our military do not bear the burden of our security alone.
