giant molecular cloud

In order to study the effect of the gravitational instability in the formation and evolution of giant molecular cloud models (GMCs) in galaxies, the differential rotation models are developed by means of computer simulation methods.

为了研究引力不稳定性在巨分子云形成中的作用，通过计算机模拟技术建立了星系中分子云的较差自转模型。

Two models of molecular cloud in disk galaxies are proposed to investigate the formation of giant molecular clouds (GMCs) under the gravitational instability and random collision using PP(Particle Particle) simulation.

关于巨分子云的形成 ,一般而言有 2种截然不同的机制 :随机碰撞聚合形成机制和不稳定性形成机制 。
