摘要
计算了粘滞演化阶段不同的吸积率下原太阳吸积盘的结构．应用标准α模型估算盘中的粘滞，粘滞参数α取０．０１．盘由粘滞扩散加热，通过对流和辐射散热．
The structure of
protosolar accretion disk during viscous diffusion stage is calculated with a variety of mass
accretion rate.The standard α model is accepted to approximate the viscous stress in the
disk,adopting α =0.01.The disk is heated by viscous dissipation and energy is transported by
convection or radiation.The dependence of opacity on temperature is important to the disk
structure.
