The multi-material structure has a polarization dependent loss less than if the components had end surfaces normal to the direction of light propagation.

多材料结构所具的与偏振有关的损失小于组件端表面垂直于光传播方向的情况。

An electromagnetic wave consists of fluctuating electric and magnetic fields, perpendicular to each other and to the direction of propagation, as described in detail in front.

一列电磁波由一系列频率的电场和磁场，它们相互垂直并垂直于波的传播方向，这在前面已详细做过说明，按照惯例，偏振方向就是电场的速度方向，而不是磁场。

In this thesis, the discreteness of bridge response excited by train will be analysed considering the relationship between system's input energy and vibration response.

本文从系统输入能量与振动响应的关系来分析桥梁车振响应的离散性。

Therefore, the discreteness of bridge response excited by train will reflect that of this system's input energy; The largest input energy will lead to the largest vibration response.

因此，桥梁车振响应的离散性反应车--桥系统输入能量的离散性；最大的输入能量产生系统最大的振动响应。

Either way the original team will be slighted and dispirited by this ?

无论是原有的团队将轻视和本不振呢？

Normal friction damper is a type of energy dissipation device in civil engineering, and has the good ability of energy dissipation.

普通摩擦阻尼器是工程结构中常用的一种消能减振装置，具有良好的耗能能力。

Base on the lumped parameter model of the torsional vibration system of crankshafts with variable inertia and considering the nonlinear elasticity force and nonlinear dissipative force, a six-degree-of-freedom nonlinear dynamical equations with parametric excitation and compulsive force are deduced.

Under this controller, the system has the fastresponse speed without the dithering, which can not be eliminated.

该控制律使得系统既具有较快的响应速度，同时不至于带来无法消除的抖振。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
