半空间饱和土在内部简谐水平力作用下的Ge函数

根据积分变换方法得出了半空间内部作用简谐水平力时的Gree函数．首先，利用Hankel积分变换方法，直接对频域内的Biot波动方程进行求解，得出Biot波动方程的通解；利用通解和半空间内部作用水平力时边界上的边界条件，以及力作用面上的连续性条件，可以得出上述边值问题的解；对于边值问题在变换域内的解进行相应的逆变换，就可以得出频域内的Gree函数．本文得到的线弹性退化解与文献中的结果吻合．最后，文中给出了两个算例．      

利用强震记录分析场地的地震反应

利用唐山近场强震记录对如何分析场地反应进行研究，分析比较了多种方法:线性反演法、传统的谱比法以及接收函数法．通过比较研究，发现各种方法都能给出土层场地的卓越周期，但每种方法给出的场地反应不完全相同．其中，传统的谱比法与线性反演法的结果较为接近，而接收函数法的结果则同其它两种方法的结果相差较大．在线性反演法中，给出了Ｓ波的品质因子QS，QS 在0.5～32Ｈz范围内与频率有关:QS（f）＝67 f 1.1．

Analysis And Simulation Of Surface-Layer Winds Using Multiplicative Cascade Models With Self-Similar Probability Densities

Statistical analysis techniques based on multiplicative cascades are investigated for use with surface-layer wind data sets collected in the atmospheric boundary layer over flat farm land. The data were found to exhibit multiscaling statistics, allowing the surface-layer winds to be simulated with the use of multiplicative random cascades. The study found evidence that, for the surface-layer at least, these cascade models (andhence the methods of multifractal analysis) should be applied in separate ways to the microscale inertial range, and the mesoscale. This is at odds with the view found in the existing literature, which proposes a `universal multifractal' model to replace the widely held view that there exists separate microscale, mesoscale and synoptic scales for which the processes governing each are different. At least two separate ranges of scaling are suggested for surface-layer wind data, corresponding to the microscale inertial range and the mesoscale. For the case of the mesoscale range, a self-similar distribution of weighting factors was found for the wind speed data themselves, rather than for an intermediate (dissipation) field, as is required for themicroscale data.

Precise determination of focal parameters for July 20, 1995 M_L=4.1 earthquake sequence in the Huailai basin

IntroductionSince the late 1970s, the quickly developed global digital seismograph network has been providing high quality recordings of large earthquakes in global scale, based on which digital seismology has made great progress. Compared with large earthquakes, moderate and small sized shocks have more frequent occurrence, and comprise clues to geological tectonics and tectonic stress field in a region. Preceding and following a large earthquake, usually occur numbers of small events that im…     

Numerical modeling calculation for the spatial distribution characteristics of horizontal field transfer functions

Introduction There are two kinds of methods for the mathematic study on electro-magnetic induction in geo-field: one is analytic method, such as integral equation method; the other is numerical model-ing method, such as finite difference method and finite element method. The analytic method can only be applied to the conductor with very simple shape, such as sphere, circular cylinder, etc. With the increasing of computing speed and popularity of computer, the numerical modeling methods are use…
