范·弗拉森的量子理论的解释思想

范·弗拉森的量子理论的解释思想不仅是他的一般科学哲学理论——建构经验论的重要科学思想基础 ,也是建构经验论在量子力学哲学中的具体体现。本文主要从量子力学作为一般科学理论的解释、量子理论的主要解释问题和量子测量的模态解释三个层次 ,深入浅出地介绍范·弗拉森的这一重要思想 ,并概括地说明它与建构经验论的关系。     

一种基于快速数值技术的电磁场分析有限元算法

提出了一种用于三维电磁场有限元分析的数值技术,即与波阵法配合使用的目标区域定位(TRL)算子.首先对波阵法进行了分析,然后对TRL算子原理进行了详细论述,并讨论了TRL算子在非线性场合应用的可行性,指出其仍能够适用并保持原来的高效率.还介绍了TRL算子在采用矢量磁位函数有限元公式中的实现.最后给出了一个三维静磁场建模的算例,分别采用TRL算子和有限元软件FEMLAB.结果表明:与FEMLAB相比,TRL算子可以节省可观的计算机资源.     

3-（6-溴吡啶-2）-2-（2-氟-6-氯苯）-噻唑酮-4的电子结构与抗HIV活性问关系的量子化学研究

采用AMI方法,对3-(6-溴吡啶-2)-2-(2-氟-6-氯苯)-噻唑酮-4(BPFCIZO)进行了量子化学计算,给出了分子的几何构型、原子的净电荷、键级、前沿分子轨道组成与能级、前沿轨道电子密度等参数．结果表明BPFCIZO分子的稳定构型呈蝴蝶状,噻唑酮环为主活性区,其上的2位C、4位N和6位O等原子很可能是其与RT酶作用的活性位点．

New results on disturbance zeros of invertible linear multivariable systems

A new results concerning the definitions of disturbance zeros via the concept of minimal order system inverses is presented in this paper. These definitions are then used to develop a new computation algorithm for locating the positions of the ‘disturbance blocking zeros’ in linear multivariable systems. Assignment of disturbance blocking zeros at desired locations in the complex plane plays an important role in rejection of all measurable or un-measurable disturbances, which may affect at the outputs in steady state. Numerical examples are given to illustrate the main results of this paper.

分层流体中弧立波的理论分析和符号运算研究

The study of solitary waves has been a subject highly popular and full of interest sinec Russell[1]first observed the solitary waves in a channel and the research on the internal solitary waves in stratified fluids is one of the branches of this subject.There are extensively internal solitary waves in the atmosphere,oceans.fjords and lakes.To study them is of academic and practical significance[2].Numerous investigators have made contributions since the theoretical work on internal solitary waves was initiated by Keulegan[3].Nevertheless,some problems remain still to be discussed,for example,the higher-order theories for one-dimensional internal solitary waves in stratified fluids of small depth,the two-dimensional internal solitary waves,the explanation of the experimental and the practical phenomena by means of theoretical analysis.In this thesis,we hope to gain an insight into the above three items by combining of theoretical analysis and symbolic computation.The following work has been completed.
