It is shown that two-component Wadati-Konno-Ichikawa equation, i.e. a generalization of the wellknown WKI equation is obtained from the motion of space curves in Euclidean geometry, and it is exactly a system for the graph of the curves when the curve motion is governed by the two-component modified Korteweg-de Vries flow. At the same time, a n-component generalization to the WKI equation is obtained. Also, starting from the motion of curves, mKdV and its symmetry recursion operator is exhibited explicitly; two- and n-component mKdV systems are obtained. It is shown that WKI systems are gauge equivalent to mKdV systems. The two-component WKI equation admits an infinity number of conservation laws and a recursion formula for the conserved densities is given by considering an eigenvalue problem together with introducing an appropriate transformation.

在二维和三维欧氏空间上，我们从空间曲线运动出发，推导出了mKdV方程以及它的用以生成高阶对称的递归算子；推导出了多元mKdV方程以及二元和多元WKI方程，并证明了WKI系统和mKdV系统的规范等价性；尔后，通过考虑特征值问题，并引入一个恰当变换，给出了二元WKI方程的用以计算无穷多守恒密度的递归公式，从而证明了二元WKI方程的守恒可积性；系统地分析了两种mKdV方程的Painleve性质，并分别给出了两种不同形式的二元和n元mKdV方程的共振点出现的规律。

By the numerical analysis of the ultimate bearing capacity of two- and three-dimensional footing under combined loading mode, the results show that the effect of alteration of underground water lever on bearing capacity of three-dimensional foundation is more than on that of two-dimensional foundation, the effect of soil gravity on bearing capacity of three-dimensional foundation is more than that of two-dimensional foundation. At the same time, the numerical calculation process of ABAQUS indicates that whether the geostatic stress is balanced or not has great effect on the numerical convergence. In view of the effect extent of dilation angle of soil on the ultimate bearing capacity and the failure pattern of foundation, the condition of two-dimensional plane strain is higher than that of the three-dimensional foundation.

复合加载模式下，通过对三维矩形基础和二维条形基础进行数值分析，结果表明：黏性土地基中地下水位的变化，对三维矩形基础极限承载力的影响程度高于对二维条形基础的影响；在求解地基极限承载力的过程中，土体重度对三维矩形基础的影响明显高于对二维条形基础的影响，同时ABAQUS数值计算过程表明，地基土体地应力能否合理平衡，对数值求解过程中是否收敛有很大的影响；就土体剪胀角对地基极限承载力的影响程度而言，二维平面应变情况下土体剪胀角对极限承载力的影响比三维情况下的影响更明显，即土体剪胀角对条形基础极限承载力的影响高于三维矩形基础。

The natural enemies group, neutral arthropod group and phytophagy arthropod group of the two sub-systems were respectively analyzed and have found that all types of arthropods of the two sub-systems can be divided into three different types of groups. The first group is which living in two habitats and the species current is few impacted by the changes of habitats; The second group is which can living in two habitats in turn ,but can transfer to another in the time the habitats was deeply disturbed ;The third one can only living in one habitats and can make the another habitats as a temporary habitats.

两个亚系统的天敌类群、中性节肢动物类群、植食性节肢动物类群分别进行分析发现两个亚系统的各类群节肢动物均可划分为三种不同类型，第一种为栖居于两种生境且物种流受生境变化影响较小类群；第二种为可依次栖居于两个不同生境，生境的变化对其物种流产生较大影响；第三种为栖居于某一单一生境，但可将另一系统作为某一虫态的临时栖境。

Through the comparison of calculation results of two methods in the uniform and the non-uniform inflow, it is found that the results by two methods are very close. The calculation results by two methods are compared with open water test, and the agreement is well. The two methods can both perfectly simulate the hydrodynamics performance of podded propeller, and the method of induced potential needs less program work and can save a great deal of calculation time and memory space. It is a simpler and effective method to calculate hydrodynamics performance of podded propellers and other combined propulsions.

经过用两种方法对均匀来流和非均匀来流条件下水动力性能的计算比较，发现两种方法的计算结果很接近，并与模型试验结果吻合得很好，但用诱导速度势的方法编程工作量较诱导速度方法少，而且还可节省大量的计算时间和存储空间，是一种计算吊舱推进器和其他组合推进器水动力性能相对简单而且有效的方法。

The first to the market to buy a 3.3 jin of Solen, the school had a fair balance, not lack of weight (easily took the hands of the scale, the hawkers did not lack the basic weight), rushed to the 168 before 4:30, LG said, Let me Inside, and so on, he went outside to see the 168 selling price of seafood, the young girl to go out at the same time we bought Solen to the woman outside the wash (later know her as the young girl close to the checkout She handed over the money), I married a curious look on the outside to wash her, did not expect to see them sent to wash and burn the whole process of their guests to the Solen Add Taipen together, and mix with the other, one by one After the water washed into another Dapen months, and then look at the list of weight, you remove a few scales of the two, this is the Solen-after guests, because our Solen she is, she did not see I have to stand behind LG, when we raised objections, she said the amount was more or less the same now that you are both 2.7, 6, are the two intestines, comrades, 3.3 Solen two of her final with water scale Only two were 2.7, we get to the stomach, how many ah!

第一次是在市场买了3.3斤的竹蛏，学校有一个公平的平衡，而不是缺乏重量（轻松了手中的规模，小贩都缺乏基本的重量），送往168前4： 30日， LG电子表示，让我内，因此，他走到外面看到168售价海鲜，年轻姑娘走出去的同时，我们买的女子竹外洗（后来知道她的作为年轻的姑娘接近结帐她交出钱），我嫁给了一个奇怪的外观外洗她，没想到看到他们送到清洗和烧伤的全过程，他们的客人的竹蛏购买Taipen在一起，与其他组合，一个又一个的水清洗后，到另一个Dapen个月，然后看看名单重量，您删除一些尺度的两个，这是竹蛏，后客人，因为她是我们的竹蛏，她没有看见我站在后面LG电子，当我们提出异议，她说，数额大致相同，你现在都7月2日， 6日，是两个肠子，好同志， 3.3竹两个她最后与水规模只有两个是2月7日，我们到达胃部，有多少啊！

As a result, this research focuses on people's perception and reaction. The framework is divided into two parts. The first part constructs the reciprocal favored treatment between individual and organization by Social Exchange Theory and the second part tries to comprehend individual's and organization's stress result from different anaclisis. It is noted that the research time window is set in the period of organizational change. It can avoid the missing of feelings by afterward recalls. In other words, the objects of our research are the organizations which are in the process of changing. Additionally, government which is making effect to re-organize is also the object of our research.

因此本研究的重点锁定在人心的感受与反应，主体共分为两大区块，前者以社会学之社会交换理论（Social Exchange Theory， SET）构筑个人与组织间平等互惠的关系，后者则建立在心理学依附理论了解个人与组织依赖的风格所导致的压力结果，且时间点选定在变革执行期间，排除事后回忆可能导致感受遗漏的缺失，因此检测对象的筛选为变革尚未完成的企业体，公部门则由於正力行政府再造运动，亦为本研究施测样本之一。

It is demonstrated that the chiral quaternary ammonium salts catalysts exhibit promising catalytic properties for the substrate. Part III: The synthesis and the characterizing of the macroporous aminomethyl resin-supported cinchona alkaloid complexes and the study on its catalytic properties The part consists of two subsections. the macroporous aminomethyl resin -supported cinchona alkaloid complexes were synthesized by the stuff (cinchonine, quinine and macroporous aminomethyl resin). Their structures were characterized by means of elemental analysis, XPS, TG/DTA; the chiral polymer-supported complexes were first used as catalysts for the reduction of ketones. Their catalytic properties for the reduction processes were investigated. The comparison of the products e.e., the conversion of the substrate among different reduction processes was employed with determined by HPLC. The effects of the time, the temperature, the ratio of catalyst to substrate, reaction solvent as well as the recycle times were also discussed.

It is learned that China's commercial real estate development there are still a number of shortcomings, one of which is the development of the concept of the blind, and some commercial real estate development companies inaccurate positioning of the project, the development of the commercial format is not clear, there is no sequence, such as investment management plan, which led to the development of real estate projects follow-up can not keep up; Second, the existing part of the commercial real estate development enterprises are engaged in housing construction origin, the former in order to sell an end in itself, is an obvious short-term business; while the latter is obtained through the lease operators for the purpose of long-term returns, the differences between the two was not by a clear understanding of corporate decision-makers, at the same time affected the design and planning until the latter part of the management and many other links.

据了解，中国的商业房地产的发展仍然存在着一些缺点，其中之一是发展的概念的盲人，和一些商业性房地产开发公司的定位不准确的项目，发展商业形式目前尚不清楚，也没有序列，如投资管理计划，这导致房地产开发项目的后续行动跟不上，二是现有的部分商业房地产开发企业从事住宅建设出身，前者以销售本身就是一个目标，是一个明显的短期业务；而后者则是通过租赁运营商的目的是长期回报，两国之间的分歧不是由一个清楚地了解企业的决策者，同时影响了设计和规划直至后期的管理和许多其它联系。
