摘要：
In this paper, we study the effect of particle number in the N-body simulation of the formation of giant molecular clouds. The result shows that in the case of formation by aggregation of "unit" clouds, if we take the mean density of the unit clouds to be a constant (or their effective radius to be proportional to the cubic roots of their mass), then the disruption rate of the GMCs will be independent of the initial number of unit clouds.
