二。用差分格式离散二维Reynolds方程，通过间接求解的方法，推出了中等载荷和材料参数下收敛的等温有限长线接触弹流数值计算方法，有效地克服了等温有限长线接触Reynolds方程的强各向异性所产生的数值计算易发散问题。

P wave velocity structure in the crust of the Yellow Sea region was inverted by using P wave arrival data from the earthquakes recorded by Chinese, Korea and ISC stations. Taken together with gravity anomaly and fault system, Pn velocity and anisotropy, we analyzed the relation of various geophysical anomalies and the tectonic difference in the western and eastern Yellow Sea. This work provided further information for locating the eastern Yellow Sea fault zone and the collision boundary between the Sino-Korea and Yangtze blocks.

利用中国、韩国和ISC台站的地震走时数据反演了黄海地区的地壳P波速度结构，对比重力异常和断裂体系、Pn波速度及其各向异性，分析了不同地球物理异常的相互关系以及黄海东部和西部的结构差异，为厘定黄海东部断裂暨中朝—扬子块体的拼合边界提供了新的信息。

From the evolutions of thermal parameter of temperature factor,we have discussed relations between thermal parameter and the rotationally ellipsoid.

详细分析了晶体各向异性温度因子的求解过程和它的几种数学表达形式，从它的热参数的演化，讨论了它和三轴旋转椭球体的数学关

The results show that the variograms of As, Cd, Pb and Zn exhibit anisotropy, which possibly is controlled by the distribution of ore deposits; Hg behaves strong nugget effect, which is influenced by smallscale factors, and the further study should increase the sample density.

结果表明，As、Cd、Pb、Zn元素的变异函数表现为各向异性，其方向性可能主要受矿床分布控制；Hg元素块金效应较大，表明其受小尺度因子影响较大，其进一步分析须增加采样密度。

It is only both heterogeneity and anisotropy of porous rock media that bring about sonically induced polarization effects in reservoirs.
