碩士 === 淡江大學 === 物理研究所 === 81 === Since 1916 the Einstein General Relativity was publish, there were people who continuously put forth the new points of view about universe. The solutions of Einstein equations which were brought forward by Schwarzschild and Kerr were especially the most attractive ones among these excellent scientific results. In 1916, Schwarzschild put forth Schwarzschild metric, it provided a particle which was a static spacetime model without charge. Kerr in 1963 also provided a new solution of Einstein equations, and we named it Kerr metric. It help us to understand a spacetime structure of rotational particle without charge. Both Schwarzschild solution and Kerr solution explained the basic problems of black holes. In Schwarzschild metric, it appears black holes which are at criticle radius,and criticle radius is equal to two times mass where we suppose the value of light velocity and graviation constant are one. Besides in approach to criticleradius which we also name it Schwarzschild radius, the funny property it appears is people outside think that the events happened become slowly, but thereal situation is not in this way. This is because the graviation is very large (complete collapse), so the light can not transmit to observors far away.
