波的传播

When train running on the track, there has interaction between whiles and track, and the track will bend because of the weight of wheel. The bend wave will propagate to box-beam and further to bridge pier. Then the vibration propagate to around soil through the bridge pier, which can cause the second vibration on buildings.

列车运行时，车轮和轨道间存在着相互作用，由于轮重的作用使轨道产生弯曲变形，弯曲波通过轨道垫块传给箱型梁，进一步传递给桥墩，然后振动通过桥墩向周围土中传播，从而进一步引发建筑物的二次振动。

The speed of propagation for mechanical waves, the speed of sound , is defined by the mechanical properties of the medium.

速度传播的机械波，音速，是由机械性能的介质。

In this case, the geoacoustic waves satisfying the constructive interference prefer entially propagate along the confined aquifer, and the most energy of waves is trapped within the confined aquifer waveguide.

此时，满足相长干涉的地声波将择优沿着承压含水层传播，声波的大部分能量被捕获在承压含水层波导内。

Finally, We also study coupling effects between two cylindrical leaky wave antennas and learn the effects on propagation constants.

最后，我们也探讨圆柱型泄漏波天线之间的耦合效应对传播常数的影响

The direction of propagation is in a direction perpendicular to the wavefront.

传播方向(除了各向异性的媒介物以外)是与波阵面垂直的方向。

The electric and magnetic lines of force always lie, as deduced from the theory, on planes perpendicular to the direction of propagation.

从理论可以推出，这些磁力线与电力线都处在与传播方向相垂直的平面上，因此所形成的波是横波。

In the context of the capitalist symbolic consuming logic, the boundary between the real and the fictive dissolves.

论文提要：法国思想家波德里亚认为，后现代消费社会的大众传播媒介是"超真实"拟像的制造者。

As field represents energy, all these changes spreading out in space, with a definite velocity, produce a wave.

因为场代表能，所以所有这些在空间中以一定速度传播的变化就形成一个波。

Some regularities of the wave propagation were found from this closed system.

从这个封闭系统中发现了一些瞬态波传播的规律和特点。

The total solar eclipse has brought the VLF phase to delay obviously. The mechanism of the influence of total solar eclipse on the propagation of VLF signal is discussed.

讨论了日全食对VLF信号传播影响的机理，并用&波导模&理论对这种影响进行了理论计算。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
