basing on optics orthogonal codes,this paper proposes a new design scheme of three-dimension optics orthogonal codes.in this scheme,the optics orthogonal codes can be coded not only in space-domain,in time-domain,but also in frequency-domain.it has good auto-cross relativity properties.the simulation figures show that can enlarge the coeds capacity and improve the optics optical communications system performance.so it will be of interesting in coming high dense communication system.

To these aims, 65 primary school students were divided into two groups by Conners Teacher Rating Scales: behavior disordered and normal students firstly. Secondly , based on the characters scales, we analysed the characters of the initial sandtray of the 65 students. Last used logistic regression on the date of the two ones in order to find the diagnostic characters of behaviors problem children.

为了达到以上研究目的，本研究使用Conners儿童行为量表作为测量工具，将65个小学生被使分为行为问题儿童和正常儿童，再按照研究者在理论和临床经验基础上总结出来的初始沙盘主题特征编码表，对这两组小学生的初始沙盘做编码分析和计分，最后用logistic回归分析找出对行为问题儿童具有诊断意义的沙盘主题特征。

In this part, the set of CODONs is extended so that both open and closed curves containing straight lines and cusps can be completely represented.

该部分研究主要将传统的基于封闭光滑轮廓的CODON编码推广至任意非封闭非光滑曲线，使图像的CODON编码能更加完备地表征图像轮廓。

Basic information about the parties concerned, including their name, their customs registration codes, customs registration codes for customs declarers, and their addresses, etc.

This paper introduced code theory and the common RS codec algorithm, the implementation of RS encoder, then detailedly analyse the decoder realization of BM algorithm and ME algorithm, then bring forward implementation and improvement of a pipeline structure errors and erasures correcting RS decoder on ME algorithm, compromise the decoder complexity and delay to reduce the complexity and raise the maximum operating frequency. Finite-field multipliers optimize codec circuit.

本文首先介绍了编码理论和常用的RS编译码算法，提出RS编码器实现方案，详细分析了译码器的ME算法和改进BM算法的实现，针对ME算法提出了一种流水线结构的纠删纠错RS译码器实现方案，在译码器复杂度和延时上作了折衷，降低了译码器的复杂度并提高了最高工作频率，利用有限域乘法器的特性对编译码电路进行优化。

The possibility of researching gene mutation with the technique of gene chip was discussed. A new imagination to randomly determine DNA sequence in different living beings with the technique of gene chip was advanced. In this way, whether the encoding sequence gene in DNA of eukaryon organism has some regularity was studied.

进而提出新设想——采用基因芯片技术对不同生物群体随机抽样进行DNA测序，从而探讨在真核生物DNA分子链上编码序列遗传基因的变化是否有规则而非随机的，非编码序列遗传基因是否为生物进化过程中曾经有表达能力的结构基因，并分析可能获得的结果。

Multiple variants were detected in the promoter, exonic, intronic and 3'-UTR regions of CYP2C9, of which 16 were novel, including 7 non-synonymous exonic variants.

在新加坡多种族人群的CYP2C9蛋白编码区、启动子区、3'-未转录区和内显子区中总共发现了30个CYP2C9基因变异，其中新的基因变异有16个，包括7个蛋白编码区的错义突变。
