本文采用两步聚变模型和生存概率蒸发程序（KEWPIE）相结合的方法，计算了合成超重元素反应的剩余截面。给出了计算的理论方案，并给出了一些令人鼓舞的结果，同时也指出了一些困难。用这种方法，很好地再现了Z= 108，110，111和112的1n个反应产生元素的激发函数。因此，该模型已被用于预测导致形成Z=113和Z=114的元素的反应的横截面。
The evaluation of the residue cross-sections of reactions synthesising superheavy elements has been achieved by the combination of the two-step model for fusion and the evaporation code (KEWPIE) for survival probability. The theoretical scheme of those calculations is presented, and some encouraging results are given, together with some difficulties. With this approach, the measured excitation functions of the 1n reactions producing elements with Z=108, 110, 111 and 112 are well reproduced. Thus, the model has been used to predict the cross-sections of the reactions leading to the formation of the elements with Z=113 and Z=114.
