First we give the characterization of subsets on which every real-valued convex function bounded above is continuous on the space, and give the βperturbed optimization in Banach space by introducing new locally convex topology.

给出了广义实值凸函数在集合A上有上界则连续的一类子集的特征性刻画；并且通过引入新的局部凸拓扑的方法，给出任意Banach空间的β扰动优化。

In general,the convergent sequence and bounded set are concepts only in topological spaces.

收敛序列和有界集一般是拓扑空间中的概念，文章首先引入序列收敛C和L-空间(给出某种序列收敛关系的向量空间)，然后在其中定义有界集。

The discussion produces some useful result:theconvergence of bounded subfeasible solution sequence and the convergence to zero of thesubfeasible dual gap.

在引入摄动的思想下，针对受摄动KKT系统，首先证明了以上四个规划问题中线性规划及其Wolfe对偶问题解的存在性，在此基础上得到一个关于其有界次可行序列收敛和次可行对偶间隙收敛到0的重要结论。

The damage bounding surface concept is introduced to develop the modified four parameter Hsieh-Ting-Chen model.

通过引入损伤边界面的概念，导出了包含损伤变量的四参数Hsieh-Ting-Chen 边界面模型。

Then the particle swarm optimization is introduced to collision detection area. In this dissertation, it also proposes two novel framework which combines the exist techniques of hierarchy bounding volume and surface simplification with the PSO. We have tested the frameworks in our "Haptic Interactive System ". The new frameworks performance well for most models in virtual scene.

本文探索和研究了虚拟环境中广泛使用的碰撞检测算法，尝试把几何模型的碰撞检测问题转化为优化搜索问题，把粒子群优化搜索技术引入碰撞检测领域，并结合碰撞检测领域现有的层次包围盒技术和网格简化技术，组成新颖的限时干涉检测算法框架，即用户可以方便地控制分配给碰撞检测算法的时间，尝试去克服这一技术瓶颈。

When it came time to introduce the idea of a ruthless bounty hunter type for the series, it was a natural fit.

当需要为这个系列引入一个残忍的赏金猎人形象的角色时，他很自然地就契合上了。

Meanwhile, it is aware that knowledge management is becoming not only a new bourn of enterprise information management but also the key factor which an enterprise can prevail competitive advantages.

同时，人们意识到，知识管理是企业信息管理的新境界，也是企业获取竞争优势的关键因素，因此，把知识管理引入到企业信息门户中，使EIP真正成为知识共享、传播和应用的平台，己经成为一个重要的发展趋势。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
