决策单元的变更对共协调性的影响

本文将对共协调分析的灵敏度问题进行研究,着重探讨决策单元的变更对共协调性的影响。     

定态微扰论的一种处理新方法

利用渐近方法,直接由Ｌａｇｒａｎｇｅ常数变易法求解含微扰项的Ｓｔｕｒｍ－Ｌｉｏｕｖｉｌｅ本征值问题．最后举一实例证明,与传统的展开法（结果为无穷多项）相比较,两种方法完全一致,等价,适用范围也相同,而且本文所述方法简明（一般只含两项）更具有一定的物理意义     

矩形槽水中非传播孤波[英文]

本文主要研究在外部驱动下浅水槽内部的非传播孤波，用渐进方法中的多重尺度法较详细讨论和导出波动振幅所满足的非线性薛定谔方程及其非传播单孤波解。采用一些近似条件，又可以由非线性薛定谔方程得到两个独立的线性拉普拉斯方程。     

Dynamics of Coupled Quantum-Classical Oscillators

The dynamics of systems consisting of coupled quantum-classical oscillators is numerically investigated. It is shown that, under certain conditions, the quantum oscillator exhibits chaos. When the mass of the classical oscillator increases, the chaos will be suppressed; if the energy of the system and/or the coupling strength between the two oscillators increases, chaotic behaviour of the system appears. This result will be helpful to understand the probability of the emergence of quantum chaos and may be applied to explain the spectra of complex atoms qualitatively.
