In this paper the mathematical models and methods for GPS single-point positioning are studied systematically on the theory.All kinds of error correction formulas are studied,such as ironsphere correction,troposphere correction,relativistic effect correction,earth rotation correction ,earth tides correction ,satellites antenna phase center offset correction. GPS single-point positioning programs is coded with pseudoranges and broadcast ephemerides,phases and broadcast ephemerides,and phases and precise ephemerides.And a great amount of computation has been done using the data collected .The results are computed with the 24 hour pseudoranges observation data before and after the canceling of the SA.

The mechanism of the dehydrogenation reaction of Os〓 with methane The minimum energy reaction path of this reaction is found not to be one of three PESs of a certain spin state, but to involve the crossings between each two adiabatic surfaces of three spin states.

本文主要用UB3LYP方法，结合相对论赝势，系统地研究了气相Os〓及其氧化物阳离子OsO〓（n=1-3）与甲烷的反应以及气相FeO〓与乙烯的反应的机理。

Basing on the derived equation, a new mechanism for SGMF is proposed, in which the magnetic field is produced by the ionization front. In addition we discussed properities of the SGMF produced by ponderomotive force mechanism and by the inverse Faraday effect mechanism.

从Maxwell方程出发推导出一个描述自生磁场的相对论方程，以此为基础，研究了有质动力，逆法拉第效应机制下产生的自生磁场的特性，并提出了一种新机制—运动电离波前机制。

The present dissertation gives experimental, theoretical and PIC simulative research on the plasma-filled two-stage backward-wave oscillator and free-electron laser . In experiment, both an unmagnetized plasmafilled and a magnetized plasma-filled RBWO-FEL are studied.

Based on the analysis of the Jahn-Teller effect,vibronic interaction and the resolution of group representations, the possiblegcometrical configurations of 〓 have been derived for the first time, the results arein good agreement with the calculation esults.Firstly, the reasonable dissociative limits for the diatomic molecules of ZrCo,ZrH, CoH, UH,〓 and AlNi have been derived based on the Atomic and MolecularReactive Statics and the resolution of group representations. The groundelectronic states, which are 〓,〓,〓 and 〓 respectively for thesemolecules, have also been optimized based on the RECP method.
