约束

The former is bound by operator gen and the latter is bound by existential quantifier.

类指性由类指算子gen约束，存在性由存在量词约束。

It transforms the primal problem into an ordinary optimization problem with an explicit dual function and simple constraints, with smaller size than primal constraints. It is convenient for engineering application.

该方法不仅给出了原问题显式形式的对偶函数，而且对偶变量的数目仅等于原问题部分约束的个数，原来的线性0-1规划问题被转化为只有简单约束的普通优化问题，极大地方便了工程应用。

Interval slope method is proposed for a class of unconstrained min-max-min problems, in which the objective functions are factorable functions. An interval algorithm is given by interval slope discard tests and interval extension of objective functions. Numerical results are also presented.

In order to transfer the experimental JR curves from laboratory to real cracked components, a mathematical expression representing a family of the JR curves was constructed for steel 18G2A by using the test data of JR curves for the SENB specimens.

同时，为了将实验得到的18G2A钢的JR曲线应用于实际裂纹构件，建立了JR曲线与约束参数A2之间的关系，给出了与约束参数A2相关的JR曲线族的表达式。

Based on constraint satisfaction,an entirely feasible scheduling is obtained by constraint propogation technology and heuristic repair method and is regarded as initial solution for tabu search algorithm.Current solution is optimized by neighborhood transformation on a critical path.The final optimizal solution is improved by adopting a global neighborhood swapping strategy.

该算法基于约束满足思想，通过约束传播技术和启发式修复算法，得到可行调度作为禁忌搜索算法的初始解；再进行关键路径上的邻域变换，优化当前解；并采用一种全局邻域交换策略，扩大搜索空间，改善优化结果。

Secondly, make amendments to the initial feasible direction in order to adapt it to all the inequations of the optimization model.

具体做法是：首先对非线性优化模型中所有等式约束条件实施拟牛顿迭代法，求得一个可行方向，然后对这个可行方向进行修正，使之满足线性和非线性的不等式约束条件，最后收敛于问题的最优解。

The method of calculation of fiber model numerical value that established steel tube to restrain a ferroconcrete to control curved component part, use in computation follow the addition of load and increase steel tube to be opposite ceaselessly the restrains effect method of core concrete, numeric computation result and test result be identical are good.

建立了钢管约束钢筋混凝土压弯构件的纤维模型数值计算方法，计算中采用随荷载的增加而不断增大钢管对核心混凝土的约束效应的方法，数值计算结果和试验结果吻合良好。

I wish I were a free agent, but my contract binds me for three more years.

我要是不受约束就好了，可是我的合同还要约束我三年

Unconstrained means that the side itself is not attached to a position (i.e. it is a free variable), but other sides may be constrained by it.

约束意味着方本身没有连接到一个位置，但其他方面可能会受它的约束。

Regarding iterated processes as objective function,parameters of algebra iterated system as design variables,and boundary condition of iterated variables as constrains,a new optimum method was proposed,which was used to calculate bifurcation of Logistic mapping.

以迭代过程关系构成目标函数，参数为设计变量，迭代变量的边界为约束，建立关于分支值计算的新方法含约束条件的最优化程序算法。

I will endeavour to find you some assistance.

我尽力帮你找人帮忙。

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
