Abstract：
The dependence of phase transition,associated with the disassembly of hot nuclei,on the mass number of hot nuclei is investigated.By studying six hot nuclei ranging from ⁵⁶Ni* to ²³⁸U*,we find that in the curves of excitation energy of hot nuclei vs.Thermodynamic temperature T(E*) of ⁶³Cu* and heavier ones there are always two temperature plateaus,but in T(E*) of ⁵⁶Ni the first temperature plateau (at lower excitation energy) shrinks into a kink.
