氢原子的固有电偶极矩

用经典力学和双波量子力学计算了氢原子的固有电偶极矩。双波量子理论算得的结果在经典极限下与经典力学的结果一致。普通量子力学对氢原子Stark效应中表现出来的电偶极矩难以做出很好的解释，因为一个波函数描述的是系综而不是单个粒子。经典力学和双波量子力学可描述单个粒子的行为，对永久电偶极矩的计算和解释显得自然而合理。     

Three Types of Expression in Dark-Soliton Perturbation Theory Based on Squared Jost Solutions

Three types of expression in the dark-soliton perturbation theory based on squared Jost solutions are invesgigaged in ghis paper. It is shown that there are three formally different results about the effects of perturbagion on a dark soliton, and it is proved by means of a transformation between two integral variables that they are essentially equivalent.     

C60量子点与磁性电极的耦合

在磁电子学领域，自旋极化输运与分子器件的结合是一个热门研究方向．最近，来自美国康奈尔大学的Pasupathy等，采用纳米加工技术，将单个C60分子吸附在一对Ni电极之间，构成了“铁磁电极-C60量子点”器件．量子点的Kondo效应和铁磁性交换耦合，原本是相互排斥的，在Pasupathy的实验中，两者被首次结合在一个器件中并加以观察．研究结果表明，如果器件的质量能够保证两种效应之间的竞争得到有效控制，

Time-Resolved Femtosecond Degenerate Four-Wave Mixing in LiNbO3：Fe,Mg Crystal

Forward degenerate four-wave mixing （DFWM） processes are investigated with a femtosecond pulsed laser in lithium niobate crystal doubly-doped with magnesium and iron （LiNbO3：Fe, Mg）. The pulse energy dependence reveals a pure third-order nonlinear response, and the third-order nonlinear susceptibility x^（3） in the material is evaluated to be 4.96 × 10^-13 esu. The time-resolved DFWM process shows a response time of x^（3） shorter than 100fs, which is due to the nonresonant electronic nonlinearities. Our results indicate that LiNbO3 crystals have potentials for ultrafast real-time optical processing systems, which require a large and fast x^（3） optical nonlinearity.     

New Compacton-Like and Solitary Pattern-Like Solutions of （2＋1）-Dimensional Generalization of Modified KdV Equation

Recently some （1＋1）-dimensional nonlinear wave equations with linearly dispersive terms were shown to possess compacton-like and solitary pattern-like solutions. In this paper, with the aid of Maple, new solutions of （2＋1）- dimensional generalization of mKdV equation, which is of only linearly dispersive terms, are investigated using three new transformations. As a consequence, it is shown that this （2＋1）-dimensional equation also possesses new compacton-like solutions and solitary pattern-like solutions.

聚氨酯泡沫塑料磁控溅射镀膜工艺

机械加工后的聚氨酯泡沫塑料，由于破坏了模塑成型的外表面膜层，材料本身多孔隙暴露在空气中，极易受潮、变形，孔隙吸附的气体对真空度有严格要求的镀膜造成极大困难，材质疏松不利于膜层结合，其低熔点的性质也使镀膜工艺的选择受到限制。采用合适的前处理技术和磁控溅射镀膜参数，可以在保证制造精度的前提下镀得一定厚度的不锈钢膜层，为该类产品提供有效的防护。
