薄吸积盘及其发射线的研究

MAGNETIC VISCOSITY AND SELF-GRAVITATION ACCRETION DISK MODEL

在轴对称、几何薄、光学厚吸积盘模型的基础上，应用新的粘滞定律（磁粘滞为主）以避免标准吸积盘内区的热不稳定及粘滞不稳定定。考虑了自引力的作用，计算出了稳定的磁粘滞自引力薄吸积盘外区的结构，综合盘外区的结构，讨论了吸积盘外区的辐射性质以及发射线的有关问题．

We present a magnetic accretion disk which includes the effect of self-gravitation, and give the vertical structure of the disk. In this paper, we use new viscosity law in which magnetic viscosity is mechanism in stead of that of the standard α-model in order to avoid the thermal instability and viscous instability in the inner region of standard disk. Associating with structure of disk in the outer region, we discuss the properties of emission line 1n the disk.
