QoS multicast routing problem is a nonlinear combinatorial optimization problem,which has been proved that the problem is NP-complete problems.

QoS组播路由问题是一个非线性的组合优化问题，已证明了该问题是NP完全问题。

Although the IPv4 has already obtained to make the person is hard to place the success of the letter, along with lately- apply flow out continuously now, the traditional IPv4 agreement is hard have already supported an Internet to extend further with the characteristic of the new business, among them the most attractive with the most remarkable of can improve it to be placed in in its address space of size, expand a sex problem,manage a problem and choose road in addition a difficulty,service of the consignation and the safety problem of the improvement and the service quality characteristic is also convex appear, so the IPv6 transitions become no time for waiting now.

虽然IPv4已经取得了令人难以置信的成功，但随着新应用的不断涌现，传统的IPv4协议已经难以支持互联网的进一步扩张和新业务的特性，其中最显眼和最值得注意的可改进之处在于其地址空间的大小，除此之外扩展性问题、管理问题、选路困难、服务的改进和服务质量特性的交付以及安全性问题也凸现出来，因此现IPv6过渡变得迫不及待了。

The user's utility is a function of his data throughput, thus the bandwidth resource utilization problem is modeled as a utility based constrained maximization problem, called a system problem.

通过设置站点吞吐量的对数效用函数，将带宽资源的有效利用问题建模为系统效用最大化问题；应用最优化理论将此系统问题等效为可分布式求解的用户问题，即各站点只须独立选择最大化其净效用的竞争参数，则系统整体效用也获得最大化。

An exceptional condition is a problem that divvents the continuation of the method or scope that you're in. It's important to distinguish an exceptional condition from a normal problem, in which you have enough information in the current context to somehow cope with the difficulty. With an exceptional condition, you cannot continue processing because you don't have the information necessary to deal with the problem in the current context .

异常条件是阻止你的方法正常运行的一个问题，在普通的问题当中分别出这些异常的条件是很重要的，对于普通的问题在当前的环境中你有足够的信息来应付这个难题，但是对于一个异常条件你则无法解决因为在当前的环境中你没有足够的信息来处理这个问题。

In the first part, convex duality method linearizes convex wealth equation, and the introduction of Lagrange multiplier converts original problem to an unconstrained static optimum problem. At last, we obtain another equivalent optimum problem with convex control domain.

文章前一部分运用凸对偶的方法先将财富方程线性化，Lagrange乘子的引入使最优问题等价与一个无约束的静态最优问题，最后转化为一个凸控制域的最优问题。

To increase the running speed of the collision detection algorithm, a new approach is proposed, which uses convex Bounding Volume Hierarchies to express convex polyhedron. Thus the distance problem of two convex polyhedrons is come down to a nonlinear programming problem with constraints. The nonlinear programming problem can be solved by simulated annealing genetic algorithm.

为了提高碰撞检测算法的速度，提出用顶点的凸包表示凸多面体，将两个凸多面体间距离的问题归结为一个带约束条件的非线性规划问题，利用模拟退火遗传算法对该问题进行求解。

For the first task, unnecessary holes inside of the model should be avoided, and non-interest front regions should be excluded. For the second one, three fundamental problems of reconstruction: the correspondence problem, branching problem, and tiling problem should be handled properly.

前者主要考虑如何避免提取模型内部不必要的空洞、和快速去除非兴趣区域的骨质影响；后者主要考虑如何解决表面重建中的轮廓对应和分支问题、以及如何提高轮廓拼接的准确性与效率。

The two stage method by-passes the correspondence problem and ill-posed problem encountered in the general motion analysis, and avoids the local minimum problem of the spatial-constrain-based iteration method.

本文推广了全景图象方法和外极面图象方法，从而使之能适用于具有抖动的图象序列分析，并避免了一般运动视觉方法的不适定问题和特征对应问题、基于空域约束的迭代方法的局部最小化等问题。

Or three deer inner parts go into a factory factory an examination a personnel to collaborate with supplier, add with the protein content low raw material three chlorine cyanotype the An get by under false pretenses combine factory, in fine must find out to arise problem of link, find out a responsibility person, this kind of matter must someone be responsible for and also only thoroughly check pure problem, punished a responsibility a person, then can be real to let three deers start to re- set up the image of race brand in the consumer in front, otherwise no one's good-bye believe this brand, can imagine, if three deer company oneself not and actively resolve a problem, the affairs will become it this time of business enterprise judgment day, have to understand, the consumer is God, 1 connect consumer life safety and healthily can arbitrarily neglect of business enterprise, end it will pay the most heavy price of for this.

还是三鹿内部的入厂出厂检验人员与供应商勾结，用蛋白质含量低的原料添加三氯氰胺蒙骗过关并出厂，总之一定要找到发生问题的环节，找出责任人，这种事一定要有人负责，也只有彻底的查清了问题，处罚了责任人，才能真正让三鹿在消费者面前重新树立起民族品牌的形象，否则没有人再会相信这个品牌，可以想象，如果三鹿公司不自己主动解决问题，这次事件将成为它的企业末日，必须明白，消费者才是上帝，一个连消费者生命安全和健康都可以任意忽视的企业，最终它将会为此付出最沉重的代价。

Chimborazo and Cotopaxi, took me by the hand.
