Theoretical α-decay half-lives of the heaviest nuclei are calculated using the experimental Qα value. The barriers in the quasi-molecular shape path is determined within a Generalized Liquid Drop Model (GLDM) and the WKB approximation is used. The results are compared with calculations using the DensityDependent M3Y (DDM3Y) effective interaction and the Viola-Seaborg-Sobiczewski (VSS) formulae. The calculations provide consistent estimates for the half-lives of the α decay chains of these superheavy elements. The experimental data stand between the GLDM calculations and VSS ones in the most time. Theoretical α-decay half-lives of the heaviest nuclei are calculated using the experimental Qα value.

上世纪80年代初,广东省社科院成立了全国第一家港澳经济研究中心,在港澳研究方面处于领先地位。紧接着中山大学、暨南大学等相继成立港澳研究机构。可惜的是,港澳回归后,这些机构可能认为历史使命已经完成,逐渐转移了研究对象。但港澳回归十几年来,发展道路并非一帆风顺,出现的新问题值得研究。广东在全国改革之路上肩负重任,同时建设大珠三角世界级城市群的时间节点愈来愈近,广东应进一步发挥毗邻港澳的地域优势,做好连
