An improved shceme for the old double-way authentication access control scheme based on Harns digital signature is proposed. The new double-way authentication protocol of the improved access control scheme can prevent man-in-the-middle attack and replay attack. After strict formal analysis with BAN logic, the result have proved that the authentication protocol is secure. The improved access control scheme is realized by the mode of single-key-lock-pair. Under new access control scheme, user can own several kinds of access right upon one file under the new scheme without the supposition that the access rights is increase by degrees, and the possibility of overflow problem is significantly reduced by our new method

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. However, with the increase of the wave travel path within the mummer layer, the nonlinear accumulation effect could still keep such phenomena as the waveform distortion and instantaneous dominant frequency and bandwidth variations in records.

在本文给定的弱非线性介质中（非线性炽较薄且远离震源），在震源能量较低的情况下，介质的非线性效应会造成地震波瞬时主频和频宽相对于线性介质情况分别为1/10~1/14和1/10~1/3左右的变化量此外，随着入射波能量的下降，介质非线性所造成的地震波瞬时特征的变化量减小，但随着地震波在穿越非线性介质时路径的加长，非线性作用的累积效应使得波形畸变和频率分布特征的变化等现象得以维持。
