中文摘要：
在双核模型框架下，用数值解主方程方法计算了超重核的熔合几率。明确描述了包含能量、角动量和碎片形变弛豫的相对运动，并与核子扩散过程相耦合。因此，用微观方法推导出的核子跃迁几率是与时间相关的。所计算的以Pb为靶的冷熔合超重核形成截面和以^48Ca为弹核的热熔合超重核形成激发函数与已知的实验值在合理的范围内符合。
英文摘要：
In the dinuclear system conception, the master equation is solved numerically to calculate the fusion probabilities of super-heavy nuclei. The relative motion concerning the energy, the angular momentum and the fragment deformation relaxations iS explicitly treated to couple with the diffusion process. The nucleon transition probabilities, which are derived microscopically, are related with the energy dissipation of the relative motion; thus they are time-dependent. The formation cross sections of the super-heavy nuclei from Pb-based cold fusion and excitation functions from ^4B Ca induced hot fusion are reasonably consistent with known experimental data.
