Analytical dynamic orbit improvement for the evaluation of geodetic-geodynamic satellite data

Summary Given an analytical solution (solution of the equations of motion using analytical integration techniques) an integration of the variational equations is not necessary but simply a differentiation of the analytical solution. Based on a high-precision analytical solution explicit expressions for the coefficients of the observation equations to improve state variables and force model parameters have been derived.The definition of suitable unknowns for a pure dynamic orbital improvement can be based then on an analysis of the information content of the data at hand by using those expressions.Regarding the Fourier series structure of orbital perturbations as well as the special properties of crossover difference data, the proposed technique is particularly favourable for an evaluation of Remote Sensing Data such as altimeter, SST and gradiometer data from satellites in repeating orbits.After a general discussion of the observation equations for crossover data our present results using GEOSAT altimeter data are discussed as one example for applications. Some short remarks about further applications are given.

土岭—石湖金矿床中黄铁矿的成分特征及其成因意义

河北省灵寿县土岭-石湖金矿床产于燕山期花岗闪长岩体与太古宙阜平群变质岩系的外接触带中。金矿床中黄铁矿的硫同位素显示金的成矿热液与花岗闪长岩岩浆同源。黄铁矿的主成分具有亏硫特征,属典型的内生型。从矿脉到蚀变岩及受蚀变围岩,黄铁矿的Au、Ag、As含量及Au/Ag比值降低,Co、Ni、Se含量及Co/Ni此值、S/Se比值升高。这些元素的含量及有关参数对金及黄铁矿的取样位置具有良好的指示意义,是确定矿体位置及其含金性的标志,也是成矿温度的函数。     

The remote sensing observation in experiments of rock failure and the beginning of remote sensing rock mechanics

The remote sensing observational study for infrared radiation of rocks was proceeded during the loading on rocks until failure. The major instruments used in experiments were transient spectrum apparatus, intelligent spectrum apparatus, infrared radiation thermometer, infrared spectrum radiometer, and infrared thermal imaging system. The experiments for 26 kinds of rocks were made. The studies show that infrared radiation temperature of rocks increases along with increasing of stress. The amplitude of infrared radiation spectrum of rocks also increases along with increasing of stress. The observational results of infrared thermal imaging of rocks are consistent with infrared radiation temperature. Before formation of major faults for some rocks, the belt-shape thermal imaging of temperature anomaly displaies in position of future major faults. This study has led the new technology of remote sensing into rock mechanics and tend to establish a new field in rock mechanics — remote sensing rock mechanics (or remote sensing rock physics). The application of remote sensing rock mechanics in prediction of earthquake and rock burst, and in measurement of stress field in rock mass is expected.

利用震源机制解对中国西南及邻区进行应力分区的初步研究.

将滑动方向拟合法引入应力分区的研究中,以地震震源机制解反演出的断层面上剪应力的方向和相对大小作为判定条件,对一地区的地震震源机制解进行逐一筛选,确定受各个不同构造应力场控制的地震,然后再根据地震的震中分布划分应力分区,我们称之为逐次收敛法．通过对297个地震震源机制解的反演分析,认为中国西南及邻区可分为5个应力分区,并计算出5个应力分区相应的3个主应力的方向和应力形因子的大小．
