On one side, music teaching is .the backbone of diathesis; teaching- It has very important diversifying ability for developing people. It is good for the development' of the individual character. It is good, to mold a person's temperament. It is good to train the creation ability of students. On the other side, because of the malady of conventional teaching for examination, it makes the society, shools and parents short of understanding the music teaching. Most of the schools are short of the innovation environment and the music teachers are short of innovation consciousness and ideas, which stops students from developing in thought and creative ability.

Dynamic interaction of wheel-rail is studied by using DSAS software when Blue-Arrow power car, trail car,"SS8" locomotive and passenger car with "209" bogies pass through a curve with severe rail oblique crack in Guang-Shen railway, respectively. Results of the above cases are compared and analyzed. Based on these results, effect of track structure parameter and train speed on dynamic interaction of wheel and rail in curve track is discussed, and a set of synthetic and effective technology measure which eliminates or releases rail oblique crack is put forward, The results can be expected to provide theoretic basis and guidance for engineering practice.
