使旋涡星系宏观图像保持准稳状态的物质密度和速度的波动。
密度波牵涉到恒星轨道的同步化。
得到如下一些重要结论:1。不稳定区域密度波振荡为有限的持续振荡。
The following conclusions are obtained: 1. the density wave in an unstable area develops a finite continuous oscillation.
掺杂能激发电荷密度波,从而削弱了自旋密度波,最终不利于铁磁态的稳定。
Doping can excite a charge density wave weakening the spin density wave against the stability of the ferromagnetic state.
Our friend Schr?dinger told us that if you solve for the wave function, this is what the probability densities look like.
我们的朋友薛定谔告诉我们,如果你用波函数来解决,你就会知道这些概率密度看上去的样子。
We can talk about the wave function squared, the probability density, or we can talk about the radial probability distribution.
我们可以讨论它,波函数的平方,概率密度,或者可以考虑它的径向概率分布。
But we can also think when we're talking about wave function squared, what we're really talking about is the probability density, right, the probability in some volume.
波函数平方,的时候,我们说的,是概率密度,对吧,是在某些体积内的概率,但我们有办法。
