用有效势方法讨论汤川核力场中圆轨道的稳定性

以汤川核力场为例，说明用有效势方法讨论有心力场中圆形轨道的稳定性，数学处理比较简明，物理图象也比较清晰。进而指出非径向微扰引起的速度矩变化对稳定圆轨道半径ｒ＿０的影响，导出两者变化的数量关系，说明在汤川核力场中维持稳定圆运动对微扰量所加的限制。     

心肌动作电位对心脏节律的影响

采用数值方法分析心肌动作电位对心脏节律的影响。心肌动作电位用Noble模型来描述，心脏节律用Bernardo-Signorint模型来模拟。数值分析结果表明，心肌动作电位形成的靶环波和螺旋波对心脏节律影响较大。当心肌动作电位表现为噪声时，心脏节律可完全破坏。

ON THE OPTIIMAL REACTIONS ASSEMBLAGE OF COMPLEX REACTION SYSTEMS

In this paper, the author analyzes distinguishing features of complex reaction systems and single reversible reaction, and optimizes complex reaction systems starting from set theory.The method of constructing the optimal reactions assemblage and calculating the potential maximum equilibrium yield (PMEY) of objective products is proposed here. This paper points out clearly that the euqilibrium yield of objective products calculated by means of conventional method is the global equilibrium yield (GEY).It is not the thermodynamic constraint, and could be exceeded by observed yield of objective products; only PMEY is the thermodynamic constraint. It gives information on potential and possible optimal yield and thereby improving production. This paper also points out the way in which the real complex reaction system approached the optimal reactions assemblage. The new concept of PMEY and optimal reaction assemblage proposed by this Paper is universally applicable for the important complex reaction systems, such as the pyrolysis of alkane to produce ethylene, steam reforming of methane to produce syngas, production of formaldehyde from methanol, epoxidation of ethylene to produce ethylene oxide, hydrogenation of benzene to produce cyclohexane.
