| 摘 要： | 近十几年来,人们已经对吸积盘进行了深入的研究。前人很多工作都是解析工作。虽然解析工作能够简单明了地揭示盘的许多重要性质,但吸积盘的很多重要性质(例如:对流和外流)没有办法通过解析工作进行深入的研究。数值模拟是研究天体物理的重要手段。近十年来,随着计算机技术的迅速发展,数值模拟在天体物理研究中扮演了越来越重要的角色。本论文主要用数值模拟的手段研究吸积盘中一些重要的物理过程。

| Abstract: | Accretion disks have been investigated intensively these years.A large fraction of previous works analytically investigate the disk properties.Analytical method is very simple.But it can not investigate some important properties of accretion disks such as convection and outflow.Simulations is very important for astrophysical research.With the development of computer science,simulations become more and more important.In this thesis,we mainly use simulations to investigate some important process in accretion ... |
