Schwarzschild radius

1

The Schwarzschild radius of a solar mass black hole is about3km .

太阳质量的黑洞的史瓦西半径约为3公里。
2

The Schwarzschild radius is now known to be the radius of a non-rotating black hole , but was not well understood at that time .

史瓦西半径就是现在知道的非旋转黑洞半径，但是在那时不是很好理解。
3

To be sucked into a black hole , one has to cross inside the Schwarzschild radius .

物体要被吸人黑洞，必须要穿过希瓦兹凯尔德半径。

One strange feature of his work was that at a certain distance from the star - to be known forever as the Schwarzschild radius - the equations would go kerblooey .

他的解有个奇怪的特性：当与恒星达到一定距离时——被称为史瓦西半径——这个方程就会坍塌。
