对于超重元素的合成，必须将聚变过程分为两步：克服库仑势垒和越过条件鞍点或脊线。为了便于理解聚变阻碍的机理，我们首先对鞍座采用了一个带有倒抛物线的解析模型。然后，给出了冷聚变的实际计算结果。本文还讨论了该模型的模糊性，为今后的研究提供了参考。由于该模型是通用的，因此它适用于具有富中子弹和/或靶的入射通道。这些都是在Z=114和N=184附近的所谓超重岛上合成核素所必需的。
For the synthesis of superheavy elements, it is indispensable to divide the fusion process into two steps : Overcoming the Coulomb barrier and passing over the conditional saddle or the ridgeline. To facilitate the understanding of the mechanism which explains the fusion hindrance, we first employ an analytic model with an inverted parabola for the saddle. Then, results by realistic calculations are given for the cold fusion. Ambiguities of the model are also discussed for future investigations. Since the model is general, it is applied to incident channels with neutron-rich projectiles and/or targets. These are necessary for synthesis of nucleides in so-called superheavy island around Z=114 and N=184.
