The formation of giant molecular clouds (GMCs) by aggregation in a rigidly rotating diskgalaxy is studied.
分析在聚合形成机制下，巨分子云在刚体自转盘中的形成过程。

The absolute value is small, but the long term influence to the evolution of the dynamics of the diskgalaxy is not negligeable.
这个扭矩虽然量级很小，但对盘星系的角动量演化是一个长期的效应。

The bizarre configuration could have been caused by the chance capture of material from a passing galaxy by the diskgalaxy, with the captured debris strung out in a rotating ring.
