摘要：

The temperature dependent width of the fission fragment distributions was simulated in the Langevin equation by taking two-parameter exponential from of the fission fragment mass variance at scission point for each fission event. The result can reproduce experimental data well, and it permits to make reliable estimate for unmeasured product yields near symmetry fission.
