According to the similarity between the boundary conditions on the MHD discontinuity and the equations of the MHD simple wave, a physical quantity U called the characteristic velocity of MHD shock has been introduced. U is defined by Eq. (4) as the ratio of the jump of total presure p to that of density p, and equal to the geometric mean value of the shock velocities W relative to the up and down streams (Eq. (5)), approaching to the MHD wave velocity U in the weak shock limit.The system of equations (7)...

According to the similarity between the boundary conditions on the MHD discontinuity and the equations of the MHD simple wave, a physical quantity U called the characteristic velocity of MHD shock has been introduced. U is defined by Eq. (4) as the ratio of the jump of total presure p to that of density p, and equal to the geometric mean value of the shock velocities W relative to the up and down streams (Eq. (5)), approaching to the MHD wave velocity U in the weak shock limit.The system of equations (7) express the shock relations with U as the strengthparameter, where u, v =H/4π~(1/2) and U± are respectively the velocity of fluid relativeto the shock front, and of the Alfven and the magnetosonic waves. These relations simplify the usual shock calculations and degenerate into the formulae for the MHD simple wave (Eq. (11)) in the infinitesimal jump limit.The fast, slow, and intermediate shock can be distinguished by Eq. (12-a, b, c) respectively. It is interesting to note that the jump formulae (7-a) and (13) show explicitly the transmission relations among the various modes of MHD shock and wave (Eq. (16-a, b, c) for the above three modes respectively), which are nothing but the immediate consequence of the compressive nature of shocks together with the conservation of mass (Eq. (14) and Eq. (15)). However, it needs a lengthy derivation to prove Eq. (16) without introducing U.

根据磁流体力学间断面的守恒条件与磁流体力学单波方程的相似性,引入了一个称为磁流体力学激波特征速度的物理量,它是激波在波前后两侧介质中传播速度的几何平均值,当激波很弱时,它趋近于磁流体力学波的速度。本文导出一组以此特征速度为强度参数的激波跃变公式,形式上与单波的公式组非常相像,从而简化了激波跃变量的计算。其中密度跃变公式本身解析地证明:磁流体力学激波与磁流体力学波传播速度之间的关系是由激波是压缩波这一特性直接决定的。

With the same prerequisite as the conventional pulse deconvolutionhas, the steps of Hilbert wavelet deconvolution can be divided as follows! firstly, to extract the wavelet by dint of the geometric mean value of the amplitude spectrum of more than one channels) secondly, to make the wavelet shaping; and lastly, to do the deconvolution. For this reason, it can get better continuity and resolution. Its effectiveness has been proved by test and favourable comments were made by experts concerned. For the cause that one deconvolution factor can be applied to a lot of channels, hence, the time for factor extraction could be saved to a great extent. In this paper, the extraction of wavelet by Hilbert transformation was examined in theory and the schemes for its implementation were presented. The technique for wavelet shaping and de-convolution were also given. Examples processed with real data were shown in this paper as well.

在具有常规脉冲反褶积(DECON)相同条件的前提下,希尔伯特变换子波反褶积是利用多道振幅谱的几何平均值求取子波,并对所求的子波作各种整形,然后作反褶积,从而有利于提高地震资料的横向连续性和分辨率.试验结果表明,效果是显著的,并得到了有关专家的好评.同时,希尔伯特变换法利用了实因果序列的性质,所以提取子波方法简单,实现方便,且一个反褶积因子可应用于许多道,节省了求因子的时间。本文介绍了希尔伯特变换提取子波的理论推导和几个实现的方案,子波整形及反褶积的方法,并给出了实际资料处理的实例。
