在以后的7个月内， mro将缓慢沉入火星大气层，并渐渐由椭圆形轨道过渡到距火星表面约185英里300公里的近圆轨道。
Abstract : a mechanical model to analyze the dynamic performance of train and transition section between roadbed and railway bridge was established a nd a series of reasonable criterions were put forward too . based on this , the init ial deformation of rails due to different subsidence of roadbed and bridge abutm ent , the effects of the direction and speed of train on the dynamic performance o f wheel / track system were studied . at last , the method to determinate the length o f transition section was suggested
