英文摘要	The two-fragment angle correlation functions of mass-symmetric ternary fragment events from highly excited nuclei produced in Ar-40+ Bi-209/Au-197/Tb-159/In-115 reactions at 25 MeV/nucleon are used to extract the mean time interval in cascade emissions (tau) of intermediate mass and heavy mass fragments (mass number greater than 20). It is shown that the mean time interval decreases from the characteristic time tau = 2000-1000 fm/c for the Ar+Bi and Ar+Au reactions to tau= 750 fm/c for the Ar+Tb reaction and to tau= 50 fm/c for the Ar+In reaction. The decay mode of hot nuclei evolves from cascade fission to simultaneous multifragmentation as the excitation energy increases and the mass of hot nuclei decreases.
