地球运动的超非线性分析

根据超非线性速度理论，研究了地球的自转状态，得知地球自转的角速度沿半径方向有突变和减小，并由此计算了地壳相对于地核的角速度差值，算得赤道表面每年西移１．７５ｃｍ，符合已报道的观测数据。

关于金矿成矿物质来源的初步探讨

近年来“矿源层”这一概念已被广大地质学家所接受，他们认为矿床中的金是从围岩中萃取的，本文认为矿床中的金来源于岩浆残余热液。在地壳深部，当丰度值高的基性岩或其他岩石，在深熔作用下产生花岗质岩浆时，同时带出许多金，当岩浆侵入到上部地壳冷凝结晶时，其中的大部金进入残余热液，最后富集成矿。

2002年甘肃玉门5.9级地震灾害损失评估

2002年12月14日甘肃玉门发生了5．9级地震，造成了建筑物、构筑物和其他工程设施的破坏。震后开展了地震现场考察与震害评估工作，在充分了解灾区概况和自然环境、社会经济、产业支柱、人口及建筑物现状的基础上，将灾区划分为七个评估区，完成了66个点的震害抽样调查工作，根据地震灾害损失现场评估系统EDLES的要求，建立了有关数据库，做出了比较科学切合实际的经济损失评估结果。     

EFFECTS OF THREE KINDS OF PHYSICAL PROCESSES ON TYPHOON INTENSITY*

This paper designs three quasi-geostrophic barotropic models with a radial/horizontal grid length being 2 kin,one in the polar coordinates,one on a stationary typhoon circulation condition and another on a non-stationary typhoon circulation condition in the Cartesian coordinates,to investigate the effects of azimuthal and radial linear advections,and nonlinear advection on the inward propagation of mesoscale vorticity and the changes of typhoon intensity.Results show that the azimuthal linear advection may result in the formation of spiral vorticity bands;the radial linear advection in a certain parameter set is able to transfer vorticity inwards,leading to a slight enhancement of typhoon;the nonlinear advection of perturbation vorticity on a stationary typhoon circulation condition may transfer more vorticities inwards,thus resulting in a distinct enhancement of typhoon;and the nonlinear advection on a non-stationary typhoon circulation condition possesses duality,i.e.on the one hand,the advection increases the vorticity of inward propagation,thus favorable to the intensification of typhoon,and on the other hand,in the inward propagation process of vorticity the originally concentric and axisymmetric structure of typhoon basic flow is damaged,and a complex flow pattern forms,which in turn tends to weaken the circulation of typhoon.At last the paper discusses the possible applications of those results in typhoon intensity prediction.     

嫩江断裂构造及其与地震活动的关系

本文从卫片解译、钻孔资料、地球物理场特征等方面阐述了嫩江断裂的存在标志，同时对该断裂的性质、活动时代及其与地震的关系进行了讨论。认为沿该带分布的北西向及东西向断裂活动与地震关系密切，尤其是存在的地震围空区值得密切关注。

大坂山隧道地下水动态分析及对隧道作用评估

Base on the groundwater yield, water temperature and hydrochemistry change of the groundwater, we can analyze that the summer water content is obviously greater than winter water content where the in and-out wall rock of the Daban Mountain tunnel. The groundwater supply has the extensity and the seasonality. The groundwater content of the middle tunnel wall rock changes relatively steady, mainly supply through horizontal direction. And the total groundwater content is relatively little and steady in winter. The water pressure of the wall rock cranny is little. It has the fluent drainage system to dredge groundwater, which cannot constitute a threat to the tunnel lining. And the cold-proof sluice hole can normally work to drain water.
