摘要
An A-dependent temperature has been found both for the primary fragments and for the measured fragments in an improved isobaric-yield-ratio-difference method, which obeys the function T = C(1 - k . A), with C and k being parameters. Within the finite temperature range, the A-dependence of the difference among the free energy and binding energy is found to depend on A in the form of y = 1/C(1 - k . A). For the measured fragment, the temperature obtained by the improved isobaric-yield-ratio-difference method depends on A in the manner of T = 1/C(1 - k . A) within T <= 4 MeV. The A-dependence of temperature can be explained by the A-dependence of the isobaric difference among free energy in a natural way.
