• And when we define that as r being equal to zero, essentially we're multiplying the probability density by zero.

    当我们定义r等于0处,事实上是把概率密度乘以0.

  • And when we take the wave function and square it, that's going to be equal to the probability density of finding an electron at some point in your atom.

    当我们把波函数平方时,就等于在某处,找到一个电子的概率密度。

  • That says that if you have independent probabilities, then the probability of two events is equal to the product of their probabilities.

    意思是,几个相互独立的事件,其中两个事件同时发生的概率,等于他们分别发生的概率的乘积

  • Ever since this was first proposed, there has never been any observations that do not coincide with the idea, that did not match the fact that the probability density is equal to the wave function squared.

    从未有,任何观测,与它相抵触,从没有过,波函数的平方不等于,概率密度的情况,关于马克思,波恩。

  • You can also have angular notes, and when we talk about an anglar node, what we're talking about is values of theta or values of phi at which the wave function, and therefore, the wave function squared, or the probability density are going to be equal to zero.

    我们也可以有角向节点,当我们说道一个角向节点时,我们指的是在某个theta的值,或者phi的值的地方,波函数以及波函数的平方,或者概率密度等于零。

  • We'll introduce in the next course angular nodes, but today we're just going to be talking about radial nodes, psi and a radial node is a value for r at which psi, and therefore, 0 also the probability psi squared is going to be equal to zero.

    将会介绍角节点,但我们今天讲的是,径向节点,径向节点就是指,对于某个r的值,当然,也包括psi的平方,等于,当我们说到s轨道时。

  • We call that a node, r and a node, more specifically, is any value of either r, the radius, or the two angles for 0 which the wave function, and that also means the wave function 0 squared or the probability density, is going to be equal to zero.

    节点就是指对,于任何半径,或者,两个角度,波函数等于,这也意味着波函数的平方或者概率密度,等于,我们可以看到在1s轨道里。
