Parker's hydrodynamic isothermal solar wind model is extended to apply for a more realistic polytropic gas flow that can be caused by a variable extended heating of the corona. A compatible theoretical formulation is given and detailed numerical and systematic asymptotic theoretical considerations are presented. The polytropic conditions favor an enhanced conversion of thermal energy in the solar wind into kinetic energy of the outward flow and are hence shown to enhance the acceleration of the solar wind, thus indicating a quicker loss of the solar angular momentum.
帕克的流体动力学等温太阳风模型得到扩展，以适用于更现实的多方气体流动，这种流动可能由日冕可变的扩展加热引起。给出了一个兼容的理论公式，并进行了详细的数值和系统渐近理论分析。多方条件有利于太阳风中热能向向外流动动能的增强转化，因此表明增强了太阳风的加速，从而意味着太阳角动量更快地损失。
