超短脉冲贝塞尔光束的非近轴效应对传输的影响

 对超短脉冲贝塞尔光束在近轴近似和非近轴情况下自由空间中的传输作了研究。结果表明，其空间波形在传输中保持贝塞尔形状不变，不受非近轴效应影响；然而当空间参数较大时，非近轴效应影响超短脉冲贝塞尔光束的时间波形。     

Theoretical Study on the Long-lived Complexes for the Na＋I2 Collision System

For the Na I2 collision system, theoretical study is performed on the QCISD(T) level by using ab initio method. The ab initio potential energy surfaces are got and on them the long-lived complexes are found and optimized. These results verify the crossed molecule beam experimental phenomenon and the detailed geometry structures are given for the first time. The role of the complexes in the reaction path is also described in detail.     

Direct Observation of Non-covalent Complexes for Phosphorylated Flavonoid-protein Interaction by ESI

Diethyl flavon-7-yl phosphate was synthesized by modified Atheron-Todd reaction. The result of ESI shows that the phosphated flavonoids possess stronger binding affinities toward proteins such as myoglobin, insulin and lysozyme and are easier to form the non-covalent complexes with them.     

多质负风险和

依据理赔方式，风险保险业的险种主要分为正风险和与负风险和。本文主要研究了多质负风险和的Poisson模型的破产概率Ψ（u)，证明了破产概率的Lundberg不等式，即Ψ（u）≤Ce^-Ru。 在规模波动间隔有界情形证明了Ψ（u)=e^-Ru，拓广了经典负风险和相应结果。     

A Continuation Method of Parameter Inversion for Non-Equilibrium Convection-Dispersion Equation

Based on the homotopy mapping, a globally convergent method of parameter inversion for non-equilibrium convection-dispersion equations （CDEs） is developed. Moreover, in order to further improve the computational efficiency of the algorithm, a properly smooth function, which is derived from the sigmoid function, is employed to update the homotopy parameter during iteration. Numerical results show the feature of global convergence and high performance of this method. In addition, even the measurement quantities are heavily contaminated by noises, and a good solution can be found.

飞行管理问题的实时算法

本文讨论了在一定区域空间内进行飞行管理避免飞机相撞的模型，提出了直接搜索法和非线性规划（SUMT）法两种解法，并将两种方法有机结合，得出的算法在486微机上计算时间小于10秒，误差不超过0.01度，完全符合问题的要求。本文接着给出四种不同情况分别用两种方法求解，进行比较检验，取得很好的吻合，充分说明了模型3的可靠性。本文还对模型的误差进行分析并对模型进行推广。     

The Geometric Construction of WZW Effective Action in Noncommutative Manifold

By constructing close-one-cochain density Ω^12n in the gauge group space we get the Wess-Zumino-Witten (WZW) effective Lagrangian on high-dimensional noncommutative space.Especially consistent anomalies derived from this WZW effective action in noncommutative four-dimensional space coincide with those obtained by L.Bonora etc.(het-th/0002210).
