As the vectors go around, the amplitude of the sum vector gets bigger, and smaller, and the intensity pulsates . 在矢量旋转时，合矢量的振幅时而变大，时而变小，因而强度作脉动变化。
This would result in about 1. 5 million variable amplitude stress cycles, assuming each truck produces one stress cycle . 假定一辆卡车产生一次应力循环，这将产生15百万次变幅应力循环。
Such amplitude variations would be predicted on the basis of principles governing seismic velocities in heterogeneous media . 按照在非均匀介质内确定地震速度的原理，应能预测这样的振幅变化。
(the termv1 )v1 is seen to be quadratic in an amplitude quantity, and we shall linearize by neglecting it. 项（v1）v1被看成是振幅的二次项，我们将忽略这一项而线性化。
Miss ingram seated herself with proud grace at the piano, spreading out her snowy robes in queenly amplitude . 英格拉姆小姐骄傲而文雅地坐在钢琴跟前，雪白的长袍向四面铺开，象女王的衣服一样。
Its low amplitude makes it less important as a source of disturbance in magnetic prospecting than the solar component . 作为磁法勘探中的干扰源，它的幅度很小，所以远不及太阳日变分量那么重要。
the term(浴) is seen to be quadratic in an amplitude quantity, and we shall linearize by neglecting it. 项（）被看成是振幅的二次项，我们将忽略这一项而线性化。
The possibility of temporal variations in the earth tidal amplitudes associated with earthquakes has first been suggested by nishimura . 西村首先提出与地震有关的固体潮振幅随时间变化的可能性。
Bright areas reveal undeflected or stationary nodal regions while contour lines trace out areas of constant vibrational amplitude . 亮区表示未受偏转的或稳定的波节区而轮廓线则描绘出等振幅的区域。
The transmitted information is coded into the amplitude of the pulses so that each predetermined value of pulse energy is associated with a message . 把传输的信息编码成脉冲的振幅，因而使每个预先规定的脉冲能量值对应于一个信息。
