MIT物理III—Vibrations and Waves—4.1耦合震荡和简正模 今天我们将讨论多个物体在一起的震荡,并且一个物体的震荡影响另一个物体,。因为如果它们的震荡不是相互影响的话,我们仍然可以将他们看作两个物体的震荡。一般情况下,耦合震荡都是十分复… 大灰狼唱儿...发表于麻省理工M... 量子场论第26讲:跑动耦合常数...
(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...

The subject of vibrations is of fundamental importance in engineering and technology. Discrete modelling is sufficient to understand the dynamics of many vibrating systems; however a large number of vibration phenomena are far more easily understood when modelled as continuous systems. The theory of vib...

在受迫振动和共振的研究中，我们探索了系统在外部驱动力作用下的动态响应。上节3.1中，我们讨论了驱动力的角频率大于阻尼震荡角频率和简谐振动角频率的条件下，系统的运动特性。接下来，我们通过一个具体实例深入分析。考虑一根绳子下悬挂质量为m的小球，t=0时，绳子顶端被水平移动至一定位置。系统平点...

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 ...
