     The evolution equations for the parameters of the optical Gaussian-shaped pulse in optical fibers are derived by means of variational method from the MNLS equation. Then three restricted relations between amplitude and width, frequency and chirp, width and chirp are derived. Analytical solution about the width of pulse evolves on the propagation distance is obtained.

?A new definition is put forward to a class of constraint satisfaction problems(CSP) in form of analytic constraints with multi-assignment to single variable. Based on the new definition, a series of concepts and 3 algorithms, i.e, the integer programming, inequility set and direct solution to indefinite equation, are set up through analyzing a particalar type of CSP, of which the 3rd algorithm is discussed in detail with its time complexity in worst case presented. Thus, the general analysis procedure of a...

?A new definition is put forward to a class of constraint satisfaction problems(CSP) in form of analytic constraints with multi-assignment to single variable. Based on the new definition, a series of concepts and 3 algorithms, i.e, the integer programming, inequility set and direct solution to indefinite equation, are set up through analyzing a particalar type of CSP, of which the 3rd algorithm is discussed in detail with its time complexity in worst case presented. Thus, the general analysis procedure of a class of CSPs can be described clearly to reveal the relation between CSP and classical integer programming,number theory and integer ring theory.

针对具有解析约束形式、同一变量多赋值的约束满足问题,提出了一种新的约束满足问题定义·通过一种特殊约束满足问题的研究提出一套建立在这个定义基础之上的概念和三种算法:整数规划法、不等式组法和直接求解不定方程法,详细研究了其中的第三种算法,并给出了最坏情况下的时间复杂度,从而能够比较清晰地描述一类约束满足问题的一般分析过程,揭示了约束满足问题同经典的整数规划、数论和整数环论的联系·

Linear discretetime timeinvariant feedback systems disturbed by random processes are investigated from the viewpoint of information theory. Mutual information rate is employed as a measure of information transmission in systems to formulate the basic information condition of the tracking control problem. Based on this condition, a new design constraint is derived in dealing with the "information destruction" induced by exogenous disturbance input. Such analytic constraint indicates a relation between Bode...

Linear discretetime timeinvariant feedback systems disturbed by random processes are investigated from the viewpoint of information theory. Mutual information rate is employed as a measure of information transmission in systems to formulate the basic information condition of the tracking control problem. Based on this condition, a new design constraint is derived in dealing with the "information destruction" induced by exogenous disturbance input. Such analytic constraint indicates a relation between Bode integrals of the sensitivity function and the complementary sensitivity function, and implies a requirement of the unstable poles and nonminimum phase zeros of the open loop transfer function when it is strictly proper.

针对受随机干扰的离散线性时不变系统的跟踪控制问题,采用信息论的方法讨论了系统获得有效跟踪性能的基本信息条件。从此条件出发,得出系统闭环传递函数设计的解析约束,表明了系统敏感函数与补敏感函数的Bode积分间的关系。对于开环传递函数严格正则的系统,这一约束反映了开环不稳定零极点应具备的特性。

Hypothesis of static-determinate-structure has been widely used in approximation of behavior constraints for structural optimization. The mathematical model of optimization for truss structures is presented with multiple constraints. Expressions of analytical constraints and explicitly approximate constraints based on the hypothesis of static-determinate-structure are obtained, respectively. Optimum designs are determined by using the method of relative difference quotient algorithm with analytical and approximate constraints individually for two truss examples. Comparison of the two solutions shows that the hypothesis generates no influence on optimum solutions, except for the ones subjected to stress constraints only. No influence is found when there exist global constraints, other local constraint or the local stability constraint is the most dominant constraint as well.

研究了结构优化设计通常采用的静定化假设对最优解的影响.建立了桁架结构优化的数学模型,分别得到了解析的约束条件和基于静定化假设的约束条件的近似显式表达.以两个超静定桁架为例,分别用相对微分法求解析最优解和近似最优解,比较两者后得到结论:除了仅有应力强度约束的问题,静定化假设对最优解没有影响;在仅有应力强度约束的情况下,静定化假设导致满应力准则设计,从而影响最优解;凡存在全局约束、其他局部约束或稳定约束为最严约束,则静定化假设不影响最优解.
