The time harmonics can be considered as voltages of higher frequencies applied to the windings . 时间谐波可以看作是施加在绕组上的较高频率的电压。
The jingling piano at last is silent, and the harmonic friends rally round their pillows . 叮叮当当的钢琴声终于停止，和声学会的朋友们抱着枕头睡觉了。
The dynamic loading resulting from blast, gusts of wind, or seismic forces is generally not harmonic . 由于冲击波，阵风或地震力所产生的动力荷载一般不是谐和的。
The above analysis may readily be extended to general plane disturbances not necessarily harmonic . 上面的分析可以很容易地引申到普遍的而不一定是简谐的平面扰动。
The general solution of the simple harmonic equation (3. 1) can therefore be expressed in the following alternative forms . 因此简谐运动方程（31）的通解可用下列任一的形式表示。
The case of a harmonic oscillator driven by sinusoidally varying force is an extremely important one in many branches . 在许多领域中受正弦变化力策动的谐振子是一种十分重要的运动。
