摘　　要：本文通过核的稳定性分析图对人工合成超重元素的稳定性进行了理论分析。分析表明:任何已知的两种原子核合成的超重核都是欠质量超重核,不稳定的主要因素就是质子间的排斤性库仑力的强烈作用,抵消这种作用的有效方法是采用中子渗入技术;超重元素的质子数最多不大于1002,质子数在362至1002之间的“极端”超重核估计是中子星;预计具有稳定性的质子数等于114的超重元素的质量数在299至315之间。Stability of artificial synthetic overweight elements has been analysed theoretically using a diagram of nuclear stability. It is indicated that overweight nucleus can be synthesized only when a certain amount of neutrons participate simultaneously in the synthesis. The maximum number of protons in overweight elements is 1002. The proton number of 'extreme overweight' elements of which the neutron star is possibly composed is in the range from 326 to 1002. It is expected that the mass number of the stable overweight elements with proton number 114 is in the range from 299 to 315.
