Study on the Singularity of Schwarzschild Metric

GAO Xing-ru,ZHANG Ning(Basic Courses Department of Beijing Union University, Beijing100101, China)  
According to the time-space metric, the singularity problems in the general relativity are studied. The famous singularity of Schwarzschild metric in the general relativity is investigated. Pointing out that the singularity revealed the defects of the general relativity in theory and was not the intrinsic property in the nature world. Some singularity problems in the time-space metric are due to the incorrect selection of time-space coordinates, and therefore get the false singularity. Only introducing appropriate time-space transformation, one can remove the singularity. In the general relativity, the methods of eliminating the singularity at r=r_s through the three different time-space coordinate transformation are given out. At the same time,the coordinate speeds of photon under three different time-space metrics were discussed.
