短程自引力步长的选取在分子云数值模拟中的效应

EFFECT OF THE STEP FOR SHORT SELF-GRAVITATION IN THE NUMERICAL SIMULATION OF MOLECULAR CLOUDS

通过计算机模拟技术 ,对短程力步长在星系中的分子云和恒星的演化中的作用做了详细的研究 .结果表明 :短程力步长的不同选取对于分子云和恒星的演化基本没有影响 .

The effect of the step for the short self-gravitation of molecular clouds is studied by means of numerical simulation. The result shows that the determination of step for short self-gravitation does not have effect on the formation and evolution of molecular clouds and stars in galaxies.
