xa=θinitialcos(ω0t)(2.1-15) 因此摆动的运动方程式一个简谐运动,除此之外还有很多简谐振动的例子,比如垂直的弹簧,电路中的电容,图3是三个简谐振动的实例。 图3 简谐振动的其他例子
(9.1-13)为所有波的表达式,但问题是我们如何求解出未知数 A_{m} ,这里面我们就要用到傅里叶变换。 傅里叶变换 我们知道波的振动方程,是简正模式的线性叠加,但是我们如何求解线性叠加的系数 A_{m} 呢?我们先讨论静止的波形,任何波形都可以通过之前求解的三角函数线性叠加得到,我们看一下下面的两个例子: 因为...

Vibrations and waves are closely related. However, there is a difference between vibration and wave.What is a vibration? A wiggle in time is a vibration. What do we mean though by a wiggle in time? A wiggle could be described as a back and forth movement. Therefore, a wiggle in time ...
