| 摘要: |
| 本文利用 (c，h，a) 三参数旋转体模型计算了形变核的相对表面能、相对库仑能及相对转动能。这些相对能量与具体核无关，具有普适性，可以用于核裂变动态过程的模拟计算。利用这些结果，计算了一些核的形变位能随三参数变化的情况，给出了裂变位垒高度，与实验结果符合较好。对236U的形变位能曲面作了较详细的分析，得出一些有益的结论。用 Werner-Wheeler 方法计算了形变核的惯性质量和粘滞张量随三参数变化情况，对断点线方程作了深入讨论，为核裂变动态过程的计算机模拟准备了必要的系数。 |

| Abstract: |
| Based on three-parameter rotating body model，the relative surface energy，relative coulomb energy and relative rotating energy of deformed nucleus are calculated. These relative energies are all independent of any certain nucleus they might belong to and have generality. They can be used in the calculation of dynamical simulation. According to these results，the deformation potential energies of some nuc1ei are calculated，the calculated fission barrier heights of some nuclei are in agreement with the experimental results. The deformation potential surface of 236U is drawn and analysed in detail. In addition，the inertial mass and frictional tensors are calculated by means of Werner Wheeler method. Finally，the scission point equation of the deformed nucleus is discussed. |
