For any object, there is a critical radius, called the Schwarzschild radius, at which its mass will form a black hole.
对于任何一个物体,都存在一个被称为史瓦西半径的临界半径,在这个半径以内的质量将形成一个黑洞。
We have the mass of the sun, we have the radius of the sun so you can calculate the moment of inertia of the sun.
我们知道太阳的质量,太阳的半径,所以可以计算出,太阳的惯性是多少。
It has to do, of course, with the moment of inertia, but again, it's independent of mass, radius and length.
肯定是,与时间惯量有关,再次,它与材料无关,还有半径和长度无关。
We can make some substitutions here using some of the derivation on the previous board which will give us the Planck constant divided by 2 pi mass of the electron times the Bohr radius.
在这里我们也可以,用我以前在黑板上写过的一些词来取代它,得到的是普朗克常数除以2π电子质量,再乘以波尔半径。
n So the velocity is given by this product of the quantum number n Planck constant 2 pi mass of the electron time the radius of the orbit, which itself is a function of n.
速度是量子数,普朗克常数2π乘以轨道半径的值,它自身也是n的函数。
