The system reform of the content that is taught ,difficulty and effect investigation of theoretical mechanics

In this paper, we take some reform for the content that is taught according to the reality of the reduction of rating mechanics period. For the statics, we take the system form general mechanics system in space to special mechanics system. For the kinematics, we cut off the chapter of the postural movement of rigid body. It is proved that the reform is successful by the tracking investigation of difficulty and effect of teaching.
