It is found that there are no obvious corresponding signals related to the Slichter modes claimed by Smylie (1992), Smylie et al.(1993) and Courtier et al.(2000) in the product spectral density estimates. Instead, it is found that there exist 8 common significant spectral peaks in the subtidal band in the product spectral density estimates of the SCG gravity data, which may be related to some unknown global geodynamical or geophysical effects. It is very encouraging that the central periods of three peaks of them are estimated accurately as 4.93438 ±0.00186h, 4.42734 ±0.001159h and 4.09269 ±0.00082h, respectively, and in significant accordance with the eigenperiod of the Slichter modes of the solid inner core expected theoretically by Smith (1976) with only differences of 0.4%,-1.4% and 1.0%, respectively.

初步分析结果表明，在积谱密度估计中没有Smylie(1992)，Smylie等(1993)和Courtier等(2000)发现的与内核平动振荡有关的共振信号，但存在与某些未知的全球地球物理或地球动力学效应有关的8个重要的明显公共谱峰，估计了在这些谱峰附近的重力共振参数，其中三个谱峰的中心周期与Smith(1976)理论预测的固体内核Slichter模的本征周期符合得非常好，二者之间的差异分别仅为0.4％，-1.4％和1.0％。

Insection 4.3, semi-discrete and fully discrete Fourier spectral and pseudo-spectral schemes are constructed. The convergence and stability for the schemes are proved, and the error estimates are obtained.Chapter 5, consider the damped coupled generalized nonlinear wave equations. In section 5.2, by coupled a priori estimates and Galerkin method, prove the existence and uniqueness of the global smooth solution for the periodic initial value problem and obtain the existence of global attractors.

第四章，考虑一类具耗散的广义KdV方程组的周期初值问题，在第二节中证明了整体光滑解的存在性和唯一性，得到整体吸引子；在第三节中构造了半离散和全离散的Fourier谱格式和拟谱格式，在整体光滑解存在的条件下，证明了这些格式解的收敛性，并得到了误差估计。

This article study the most three factors of influence in pre-splitting blasting , which are powder capacity per meter 、 spacing of hole and decoupling. On the basis of ANSYS/LS-DYNA and establishing 3D model about two pre-splitting holes, numerical value sumilate expanded process of the crack , then estimates effect of the rock crash by analyzing stress , otherwise estimates effect of pre-splitting blasting by expanded picture .
