When the nonlinear layer which has weak nonlinearity is thin and far away from the seismic source which be low energy, compared with the corresponding results in linear antis, the medium nonlinearity produces abort 1/10~1/4 and 1/10~1/3 differences of instantaneous dominant frequency aid bandwidth. These instantaneous feature differences of seismic waves induced by the nonlinearity of media become weaker and weaker with the decrease of source energy.
