数学物理方程讲义.第2版 - Green function method is very important in the mathematics physics . with the developing of physics , the method is more and more important and it is used more and more widely . but it is difficult for student to learn green function method
Green函数方法是求解数学物理方程中的重要方法，随着近代物理学的发展，这一方法越来越重要，应用也越来越广泛，然而， green函数方法又是初学者普遍感到困难的内容。 - Based on modern optimization theory and optimal control theory , this dissertation studies some questions as follows : 1 . the optimization model of parameter identification of three - dimensional geologic history numerical simulation , algorithm and its application geologic history numerical simulation is a basic content of basin numerical simulation , and the porosity is the major parameter in the evolution and development process of oil - bearing basin . according to the sedimentation and burial mechanism , the physical and chemical principles of oil geology , the mudstone porosity ' s non - linear parabolic partial differential equation has been established
本文应用现代最优化及最优控制理论，对如下一些问题进行了研究： 1 、三维地史数值模拟的参数辨识优化模型、算法及应用地史模拟是盆地数值模拟的一个基础性的研究内容，地层孔隙度是含油气盆地地史演化发育过程中的重要参数，根据地层沉积埋藏机理和石油地质的物理化学原理，通过引入数学物理方程概念，建立了泥岩三维孔隙度场方程，根据问题的特点，给出了方程的定解条件，对方程的动边界也给出了处理方法，并且证明了解的存在性与惟一性，在此基础上建立了以当今实测数据为拟合准则的三维地史数值模拟的参数辨识优化模型，这是一个含有二阶偏微分方程约束的泛函极值问题。 - It plays a very important role in many application , according to the point of mathematics point , its mostly application originate from equations of mathematical physics , difference equations , markov process , and so on , its purpose is to solve the problems of solid , fluid , electromagnetic , microscopic particles , system control , and etc . in practical science research and engineer applications , such as , architecture project , research of aeronautics and astronautics , bioscience , computing physics and oil reconnoiter , many large scale generalized eigenvalue problems need to be solved
它在很多应用中扮演非常重要的角色，从数学角度来看，矩阵特征值问题的应用大多来自数学物理方程、差分方程、 markov过程等。目的是为了计算固体、流体、电磁、微观粒子、系统控制等重大问题。在实际的科学研究与工程应用中，比如在建筑工程、航空航天研究、生物科学、计算物理以及石油勘探中，都要涉及到大规模矩阵广义特征值问题的计算。 - In order to overcome difficulties in the recovery of historical tritium concentration in the determination of shallow groundwater age by the method of mathematical physical model , this paper , just taking the expolatianal model as the example , deduces a new formula to calculate the groundwater age based on the equation of the tritium mathematical physical and the tritium analysis results in different times
摘要为克服应用氚同位素方法确定现代地下水年龄过程中存在的，需确定地下水系统输入项的历史背景浓度问题，本文根据地下水同位素数学物理方程，以全混模型为例，利用不同时期地下水同位素的测试结果，通过数学迭代运算，推导出计算现代地下水年龄的计算公式。
