deformation vibration 红外光谱分子振动的形式。一个由n个原子组成的非线性分子，有3n-6个振动模式；对线性分子则应为3n-5；其中2n-5个是形变(弯曲)振动。在这些振动中，运动出现在和原子之间的键相垂直的方向上。
认为振动液化形变形迹可以作为鉴别古地震标志之一。
The . vibration liquefaction trace can be regarded as one of the marks in identifying paleoearthquakes.
研究结果表明：外界振动会使谱图的线形变差、线宽增大和相位扰乱，从而降低谱图的分辨率。
It shows that external vibration will result in bad lineshape, large linewidth, and dispersive effect, thus reduce the spectral resolution.
该超声换能器采用纵向振动方式，其前盖板连接了一个半波长圆锥形变幅杆，以增大超声换能器输出端的振幅。
The ultrasonic transducer vibrates longitudinally, its front cover plate links up with a half wavelength circular conical horn to increase the amplitude of the output end of the ultrasonic transducer.
