中文摘要：

运用推广的液滴模型(GLDM)来确定锕系原子核的自发裂变势垒,采用量子力学中的WKB近似方法对相应自发裂变的半衰期进行了研究。在GLDM中,首次考虑了微观Strutinsky壳修正对裂变势垒的影响。理论计算的锕系区重核自发裂变半衰期与实验值符合得很好,表明包括微观壳修正的GLDM可以成功研究重核的自发裂变性质。

英文摘要：

The spontaneous fission half-lives of the actinides are calculated by the WKB approximation and the potential barriers are constructed by a General Liquid Drop Model （GLDM） including the proximity energy, the mass and charge asymmetry, and an accurate nucleus radius. The microscopic shell correction which plays a key role for the sl~ontaneous fission barrier is considered for the first time. The two-parame-
