摘　　要：应用不同参数的宏观-微观模型对超重核区(Z≥104)70个原子核的结合能进行计算,利用所得结果计算α衰变能,并对结果进行比较,发现新参数的结果更为理想.然后将新参数的α衰变能代入新参数的Viola-Seaborg公式,计算超重核区原子核的衰变寿命,通过对所得结果和实验值进行比较,得出研究结果与实验值符合较好的结论.The Binding energies of 70 nuclei with Z≥104 are calculated by using the macro-microscopic model with different parameters, then the a decay energies are calculated with the results, and it is found that the result of the model with new parameters is more ideal. The decay half-lives of the nucleus in region of super-heavy nuclei are obtained by substituting a decay energies into the Viola-Seaborg formul with new parameters. The conclusion that theoretical results are in good agreement with the available experimental data is achieved by comparing the results with the experiment value.
