Abstract：
Assuming fission fragments are in statistical equilibrium state at scission point,we can consider the particle number distributions of fission fragments as the fluctua-tions around some average values. and treat them by means of quasi-thermodynamicmethod. The main result is that all distributions of mass number, charge number,isotopes and elements are Gaussian distributions around some average values andwith constant variances, and that all relevant parameters depend on temperature andproperties of fragments near the most probable fission mode only. We have determinedthe values of five fundamental parameters for the case of ²³⁵U(11th, f) according tothe experimental data, and use them to calculate the other parameters. The agree-ment between theory and experiment is satisfactory.
