本文根据Suzuki and Munakata的新的效率定义,研究了两耦合布朗马达在非对称周期性闪烁棘轮和摇摆棘轮中的整流效率.这里,力是非对称的无偏外力,闪烁是无偏非对称的闪烁,模拟了复杂外界环境下分子马达的运动,根据结果可以看出传统效率定义中效率随流的线性变化关系在新效率定义下发生了变化,同时通过闪烁棘轮和摇摆棘轮单一分子马达与两耦合布朗马达的流和效率曲线,讨论了非对称参数对有结构分子马达定向输运的影响.
The production of superheavy nuclei with Z=108-116 via hot fusion reactions of the neutron-rich projectiles with 238U target is systematically studied.The results show that the production cross sections of superheavy nuclei do not decrease monotonously as the atomic number Z increasing.The cross sections of the superheavy nuclei at Z = 112 and 115 are enhanced as compared with the whole Z-trend in synthesis of the superheavy nuclei,which clearly illustrates that the reactions with large negative Q-value and shell correction are more favorable to synthesize superheavy nuclei.
