Firstly, it analyses the object of contract rescission from several angels, concludes that the object of contract rescission should be the original right and obligation in the contract, the contract itself and the right and obligation in the contract for the purpose of remedy is not rescinded. So the problem that whether contract rescission has retroactivity effect becomes the problem that whether contract rescission makes the original right and obligation in the contract vanishes retroactively.

笔者对合同解除的标的进行分析，认为合同解除的标的应该是合同内容中的原始性权利义务，合同解除后合同本身和合同中的救济性权利义务并不因合同解除而消灭，正因为此，关于合同解除是否有溯及力的问题也变成了合同解除后是否使合同中的原始性权利义务溯及地消灭的问题。

Caring classroom stresses treating person in way of life in the process of teaching, establi-shing the purpose of cultivating students'sound personality, inquiring the life problems and taking them as the link with teaching contents, advocating tolerance, respect and honesty , thus makes the classroom revivify and transcend to the living world in the process of effective construction.

Thirdly,we study certain Riemann boundary value problems and Singularintegral equations with values in a universal Clifford algebra 〓,by com-bining the classical methods of solving Riemann boundary value problems andsingular integral equations with the Taylor's expansion of regular function in Clif-ford analysis,proving a lemma which is similar to the Painleve theorem in theclassical complex analysis,and the Plemelj formula in Clifford analysis,we obtainthe better results under weaker condition than before.

第三，本文第一次借助于用来解决经典的Riemann边值问题与奇异积分方程的方法来研究Clifford分析中的某些Riemann边值问题与奇异积分方程，获得了在比以前文献中条件更弱的情况下，结论更广的结果，并且，它为更进一步地解决在Clifford分析中一般的Riemann边值问题与奇异积分方程提供了基本的解决思想，为这一新的研究领域奠定了基础。

However, viewing Schnabel's works from a museum's perspective, we will pay more attention to the originality and freshness he contributed to the practice of painting. As said in some reviews, although a bit exaggerated,"he saved American painting, that was caught up in a 1970s recession, almost entirely by himself."

可要是从美术馆的角度来看施纳贝尔的创作，我们则更为关注他在绘画方面的实践给这个领域带来的新鲜空气与强烈的刺激，就像有些评论略显夸张地称道的那样，"他几乎单枪匹马地把绘画从美国70年代的萎靡不振中拯救了出来。"

We will introduce the newest research results of computer to teachers and students through forecasting IT technology lectures and discuss together how to do useful research and development; we show to students how to show the research capacity and results and how to write normative research discourse and the like by introducing the star of tomorrow practice item of Microsoft Research Asia; via the activity to communicate with Microsoft staffs and schoolfellow we share their research experience and methods with younger students and at the same time listen to them and help them to program their future better.

我们将通过前瞻IT技术讲座，向师生们介绍计算机领域内最新的研究成果，共同探讨如何做有用的研究和开发；通过介绍微软亚洲研究院"明日之星"实习生项目，为学生们如何出色地展示自己的研发能力和成果，如何撰写规范的研究论文等方面给与实际的指导；通过微软员工和校友之间面对面的对话活动，把微软研究员们切身的科研心得和治学方法分享给更多正在起步中的学弟学妹们，同时聆听同学的心声，帮助他们更好地规划自己的职业未来。

Naturally,we confront with such a problem:can we generalizethe systematic work on the classical boundary value problem for analytic func-tions and singular integral equation to Clifford analysis?And so this problemhas especially theoretical and practical meaning,and naturally this problem hasbecome a common hot topic for mathematicians at home or abroad.

其结果在一定程度上推广了一些经典文献的结果，取消了这些在经典文献结果中对s=0或s=n的条件限制，需要指出的是，据作者所知，到目前为止，本文也是第一次系统而又比较深入地研究了取值在泛Clifford代数〓上的超复函数的性质，并获得了比较系统而又深入的结果；另外，本文还对Clifford分析中的某些比较特殊的Riemann边值问题与奇异积分方程做了一定程度的研究，由于文中所用的方法较曾经出现的文献而言有着根本的改进，因此，本文去掉了从前在这一问题的研究过程中所做出的一些不必要的条件限制，从而使得在比以往条件更弱的情况下，获得了比以前文献中更多的结果。
