Cooperating the advantages of SVM solve classification problems about small sample set, non-linear and multi-dimension model identification, I use SVM to train the sample set of different frequency signal and look for a super plane to divide the data into two parts. This method gets rid of complex computation which is a flaw of traditional decoding method.This paper introduces the theory and algorithm of SVM at first. It proposes to use the SVM to decode FSK signal based on the classifiable character of SVM.

结合支持向量机在解决小样本、非线性及高维模式识别问题中表现出的许多特有优势，运用支持向量机对不同频率信号的数据样本集进行训练，通过寻找最优超平面来对不同频率信号的数据进行快速分类，克服传统频移键控解码算法中需要进行大量运算的缺点，从而实现频移键控的解码。

The electronic structures of Dawson anion(S2Mo18O62)4- have been calculated by the discrete variational method coupled with the first principal density functional theory.And the comparison with Keggin anion(SMo12O40)2- has been made.The results show that the electrons delocalize around the all anion.But the difference of the electronic distributi on of polar and equator sites exists.

使用第一原理密度泛函理论中的离散变分方法对（S2Mo18O62）4-的电子结构进行了理论计算，并与Keggin结构（SMo12O40）2-的电子结构作了比较分析，结果表明，（S2Mo18O62）中的电子离域地分布在整个阴离子骨架中，但极位和赤道位原子的电荷分布有明显差异。

Connected with the example of SAISC, develop the studies from three aspects. First, it should be defined that the theory of CSAS(customer satisfaction alarm system) is based on the relation between demisable profit and customer satisfaction.

文章结合上海汽车工业销售总公司主要就以下三个方面展开研究：一、明确让渡价值和顾客满意之间的关系是建立顾客满意预警系统的基础理论，以营销学中的4C为核心理论，以企业流程再造为实施顾客满意体系改进的实施理论，应对传统的组织结构进行转变，形成以顾客满意为目标的价值取向；二、建立顾客满意预警系统。

First, some critical problems in crystal growth like crystal seeding, Zn dephlegmation, geometrical selection and temperature fields are discussed in theory, and the possible kinds of defects appeared in crystal growth progress and the reasons are carefully researched. To control the concentration of Cd vacancies, a new method by which the Cd vacancies were compensated with excess Cd in the Cd rich starting materials has been developed, and a new kind of two-area tube furnace with good linear temperature distribution was designed.

First, the dialogic system of academic identity is essential for literary theory to break away from a self-sealed world.

首先，学术认同的对话机制是文学理论走出自我封闭世界的基本前提。

What"s more, it has explored the unification between didactical theory and its practice, has provided cases for the reform of the teacher"s professional development and suggests on the content and method for the advanced studies for teachers.First, the paper analyzed the teachers professional development both domestic and overseas, current status of the class education and the class research ability in compute-aided environment.

本文在分析了国内外教育信息化环境中的教师专业发展、课堂教学现状以及对信息技术环境下教师课堂教学能力研究的基础上，选择了三个典型的课堂教学案例，采用了课堂观察，通过定量的弗兰德斯分析和定性的知能图谱描述对案例进行了细致的分析。

The second part makes an innovative study of the soul of traditional Chinese graphics in the respect of "shape","essence", and "implication". The first element to be emphasized is "shape", which is mainly concerned with lineal designs and convolute designs in traditional graphics, the main two ethical factors employed in traditional Chinese design. The "shape" is a relatively complete and minute system. What is included in "essence" is to convey the effect of lucency and artistic conception in traditional plastic art, which embodies traditional Chinese philosophy and its aesthetic taste. The "implication" part makes a detailed analysis of the informative function of the particular ethical graphics from the perspective of disseminative theory. The third part is my application of the three elements in designing.

第二部分是本文的创新之处，分别从&形&、&神&、&意&三方面对传统图形的精髓进行探讨，&形&主要提取了传统造型元素中的线和具有中国民族风格的构成形式——回旋形进行着重分析，有较为详细而完整的结构体系；&神&主要结合中国的传统哲学和审美思想对中国传统造型所追求的空灵、意境进行论述，&意&主要从传播学的角度对传统图形所特有的民族信息传达功能进行分析研究。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
