In pratical applications, most problems can not be discomposed into many enough inde pendent tasks. Generally, there exists some precedence constraints among tasks.

在实际应用中，绝大多数问题并不能分解成足够多的相互独立的任务，一般情况下，任务间都有或多或少的优先约束。

In reliability-based optimization problems of a ship's longitudinal structural design, there are lots of discrete variables and continuous variables. This kind of mixed-discrete non-linear optimization problem containing discrete and continuous variables has long been payed attention to, which is more difficult to solve when a number of reliability constraints are taken into account.

在船舶纵向结构的可靠性优化设计中，含有许多离散型设计变量和连续型设计变量，这种含有两种不同性质设计变量的大型结构物的混和优化问题，一直是人们瞩目的难题，尤其是考虑了多个可靠性约束条件之后，求解这种非线性优化问题就更为困难。

The limit analysis of 3-D structures is formulated as a discrete nonlinear mathematical programming problem with equality constraints by means of finite element technique.

当前极限与安定性研究的一个重要课题是研究应用的策略，寻找切实可行的计算方法，使极限与安定性理论得以在工程实际中应用。

Three solution algorithms for classical transportation continuous/discrete/ mixed network design problems are designed based on particle swarm optimization approach, in which the continuous NDP is studied in detail, discrete and mixed NDP are only described the frameworks of the solution algorithms.2. Generally, road capacity constraints must be added to the lower level problem of classical discrete NDPs bilevel programming model in order to avoid traffic assignment on candidate roads.

本论文研究工作主要有如下几个方面：(1)基于粒子群优化思想设计了求解传统的城市道路交通网络设计问题的算法，其中详细研究了连续网络设计问题，并用两个网络例子进行了数值实验；并给出了离散网络设计问题和混合网络设计问题的求解算法思路和主要步骤。

The construction of communication theory is a consequence of interaction of complex social network forces, and the forces of constraints not only come from discipline and temptations of political and economic power, but also from the growing bureaucracy and the struggle of position and power in the academic field, and even from the resistance and disesteem of the other disciplines.

传播学理论的建构是一种复杂的社会关系网络力量作用的结果，制约性的力量既有来自****和经济权力的规训与诱惑，也来自学术场域日益严重官僚做派以及学术场域内位置与权力之争，甚至还有其他学科的冷遇与抵制。
