root constant的意思|示意

In a typical tree, constant-time access is only available at the root (the node referenced by other code).

在典型的树中，常量时间访问仅可在根(其他代码引用的节点)处可用。

Yes, willpower can produce short-term change, but it creates constant internal stress because you haven't dealt with the root cause.

的确，意志力可以带来短期的改变，但因为你没有先处理问题的根源，结果反而引起内在持续的压力。

So, if we just rearrange this equation, what we find is that z effective is equal to n squared times the ionization energy, IE all over the Rydberg constant and the square root of this.

我们可以发现有效的z等于n的平凡，乘以电离能除以里德堡常数,这些所有再开方，所以等于n乘以,除以RH整体的平方根。
