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... 关于自旋-轨道耦合的 k·p 模...
令\omega=\sqrt{\frac{K}{m}}(1-4) \omega其实是有物理意义的,它的物理意义我们稍后介绍。我们现在要解式(1-3)的二阶微分方程,得到X(t)的表达式。式(1-3)的通解为: X(t)=acos(wt)+bsin(wt)(1-5) 式(1-5)有两个未知数a和b,因此我们需要将a和b求解出来,如何求解呢? 我们将用初始条件(ini...

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...

(3.1-18)中B和\alpha需要根据初始条件计算得到,我们在这里假设系统是欠阻尼,当然也可以带入过阻尼和临界阻尼的解。 这个等式中有许多个角频率,我们这里需要在解释一下: w_{0}系统做简谐震荡的角频率,不需要考虑阻尼和驱动力 \omega是给系统加入和速度成正比的阻力之后,震荡的频率,其大小为\omega^{2}=\omega...
