In the last chapter,we study the control problems of the distributedparameter system governed by a class of higher order pseudohyperbolicequation related to the symmetric regularized long wave equation.we havediscussed the controllability and optimal control problems.we have obtainedcompatibility condition of the constraint when the state is controllable,therepresentation of the optimal control for both the time optimal control problemand the optimal control problem of minimum energy type,and the equationsatisfied by the minimum time.we have shown that the optimal control belongsto the boundary of the admissible control set.

在第六章中，我们研究了与对称正则长波方程相关的一类高阶拟双曲型方程支配的分布参数系统的控制问题。讨论了系统的状态能控性问题和最优控制问题，给出了状态能控时的约束相容性条件，给出了最速控制问题、最小能量型最优控制问题的最优控制表达式和最速时间所满足的方程式，证明了最优控制属于控制集合的边界。

With the opening and progress of the economic social ,the group of women enterpriser is growing up ,which attract more and more advertence of people .the research of feminine problem in China is often staying at the right of women and children ,but today , many new problem is appearing , it is a new chance and challenge to our research, and it is a gratifying and important change .

国内对于女性问题的研究原先多停留于保护妇女儿童的权益这一层面，新时代涌现的问题更新更广更复杂，给女性问题研究带来了新的契机、提出了新的要求，从传统的"维·权问题"到今天的丰富复杂的女企业家问题研究，充分体现了女性社会和经济地位的提高，女性角色多元化的转变。

II.Based on the above fundamental solutions,the fundamental solutions ofplane and antiplane problems in two dimensional elasticity body are constructedunitedly by using the reduce dimension technique of integration and consideringtwo dimensional problems as particular cases of three dimensional ones.

将二维问题视为三维问题的特殊情形，由三维问题的基本解，采用积分降维技巧，统一导出了平面问题及反平面问题的单位集中不连续位移基本解；建立了一般边界积分方程；完成了相应的不连续位移边界元方法；给出了在断裂力学中的应用。

Studies have shown: Boy students think of knowledge counted to use early than girl student, make investigation or do experiment whether boy student think fast, touch it than girl student early; The man girl students query ability is not strong , but the thinking of the boy student is relatively more broad , the ability to pinpoint the problems is better than girl student a little ; In making decision, boy students can see essential meaning through the phenomenon a bit so, girl students seem narrow thinking , will usually confine to judging the case as it stands.

研究表明：对于从统计的角度思考与数据信息有关的问题时，男生要比女生更早想到运用统计的知识解决问题，无论是做调查还是做实验都是男生比女生想得快、动手早；在面对各种资料时，男女生的质疑能力虽然都不强，但还是男生的思维相对比较宽广，思考问题时，相对全面，发现问题的能力明显比女生强一些；在做决策方面，男生有那么一点能透过现象看到本质的意思，总是希望找到解决问题的方法，女生则显得思维面窄，通常会局限于就事论事。

However, with the rapid development of the small town, some problems and contradictions about the small town planning and construction in the Midwest Lack-developed Areas emerge by and by: lots of small towns have not transparent tactic steering and scientific economic management mechanism and pattern, leading to construction confusion, ground use squandering, environment pollution, industrial structure reasonable, infrastructure layout disharmonize; without supervise law and rule in the small town construction, leading to the small town being be out of harmony with the area, the function of small in the area is restricted; the small town resource being used freely, and the administration coming to chaos, leading to repetition construction, resource waste, and so on.

论文以"三农"问题为切入点，紧紧围绕中西部欠发达地区小城镇规划与建设所面临的关系小城镇未来发展的三个关键问题：土地利用、生态环境和基础设施建设等进行深入剖析，分析问题产生的原因：城乡二元结构是导致小城镇建设问题的主要原因；观念保守，体制不健全；财政财力不足，基础设施资金投入比例低；规划落后于建设，规划中存在非科学因素；缺乏区域设施共建共享的有效机制。在此基础上提出解决问题的对策。

It is the purpose of this paper to review the contact problems and some recent developments using BEM.

The current university is facing many questions in the scientific and technical payoffs conversion process, such as the university itself initiative capacity's deficient question, in the transition process faces a series of negotiations question, enterprise's selection and the examination question, the issue of protecting the interests of teachers and university teachers in the industry the process of what kind of role should take up other issues.

当前大学在科技成果转化过程中面临着很多问题，诸如大学本身创业能力的缺乏问题，转移过程中面临的一系列谈判问题，企业的选取和审定问题，老师利益的保障问题以及大学的教师在产业化过程中应该承担什么样的角色等问题。

The dissertation firstly introduces the MDJ1600J high speed palletizer and then lists several main problems for it which includes optimization of palletizing pattern, multiline-to-uniline problem, analysis and synthesis for feeding system, high speed turning without impact, the problem of power rating of three-phase induction motors (S1) which work with many short processes and many short switched-off processes in a period, The working principle of high speed palletizing and performance analysis for high speed palletizer, and then these problems are analysed respectively and their solution methods are presented.

本文首先对MDJ1600H高速码垛机从整体上进行了介绍，由之引出了几个高速码垛的关键问题，这些问题包括：码垛模式的优化，多线合一问题，供料系统的分析与综合，高速无损转位问题，在包括启动的多短过程多短断能间隔的断续周期工作制下采用S1制三相感应电机的功率定额问题，高速码垛动作规划和性能分析，然后对这些问题分别进行了阐述，提出了各自具体的解决方法。

From the practice of teaching, this paper explores the problems on poem teaching. Such as: Saying any thing all from books,grasping poem impractically and doctrinally,lacking the direction of methods on enjoying a poem,no training about writing,the fourth problem is only put forward. This paper analyses the causes and gives the tactics on the problems of the first three.

本文从教学实际出发，探讨了诗歌鉴赏教学中&吊书袋&的问题、整体把握的空洞与教条的问题、欣赏方法的指导的欠缺问题、诗歌写作尝试的空缺问题，对前三个问题分析了其产生的原因以及应对策略，对第四个问题只是提出而已。
