摘要：

Calculations for a set of nuclear multifragmentation data are made using a canonical and a grand canonical model. The physics assumptions are identical but the canonical model has an exact number of particles, whereas the grand canonical model has a varying number of particles, hence, is less exact. Interesting differences are found.
