Abstract: 测量了非极性分子β胡萝卜素和极性分子角黄素, 在非极性溶剂CS2和极性溶 剂1,2二氯乙烷中243–293 K的温度范围内的共振拉曼光谱. 结果表明, 溶质和溶剂的极性对拉曼光谱影响很大. 非极性分子β胡萝卜素在非极性溶剂CS2中的拉曼散射截面最大, 线宽最窄, 而极性分子角黄素在极性溶剂1,2二氯乙烷中的拉曼散射截面最小, 线宽最大. 用溶剂效应及线性多烯分子的“相干弱阻尼电子-晶格振动”, “有效共轭长度”模型给予了解释.
Multi-Lever Security Model of Electronic Commerce and Its Application
电子商务多级安全模型及其应用

Abstract: This paper summarizes today's typical security structure in electronic commerce system, then a multi-lever security model based on the traditional strategy is proposed, it avoids the disadvantage that existing security strategy severely relied on the technique and security device. The model is more emphasizes the staff-center strategy than the traditional's, it gives a new model to solve the security problem in electronic commerce system.

土地市场发育与土地利用集约度的理论与实证研究
曲福田,,<BR>

Abstract: ?市场是配置资源的基础手段和有效方式,市场发育程度的不同会导致不同的资源配置和利用效率。文章在构建市场发育与土地集约利用的理论分析框架基础上,采用因子分析法和多因素分析模型分别对江苏省开发区的土地市场化率和不同市场发育阶段土地利用的集约度进行了测算。研究结果表明,江苏省33.4%的开发区的土地市场发育处于转型后期至相对成熟期发展阶段;57.1%处于转型中期发展阶段,整体来说,市场发育较为成熟。而不同土地市场发育阶段土地利用的集约度不同,处于转型后期至相对成熟期发展阶段的开发区土地利用集约水平要显著高于处于转型中期发展阶段的开发区。因此,文章认为提高我国土地利用集约度的主要思路应是推进土地市场创新,使市场成为土地资源配置的主要机制,并作为转变土地管理机制的基本点。

Abstract: 一、人才素质培养目前时髦的谈论话题是培养21世纪跨世纪人才。面向21世纪新形势究竟需要具备怎样素质的人才,通过怎样的方式培养这样的人才,由谁来培养,如何检查,目前大学课程设置现状可否完成这个培养目标,应如何对现有课程设置和教材体系进行改革、优化,使之能在培养人才的道路上前进等一连串的课题,正在我国有关教育领域形成论坛。
Roles of olfaction and vision in orientation behavior of adult Campylomma chinensis Schuh (Hemiptera:Miridae) toward Lantana plants (Verbanaceae)

Abstract: Investigations were carried out on the orientation behavior of adult Campylomma chinensis Schuh (Hemiptera: Miridae) toward plant hosts Lantana camara, L. caniara cv. 'Flava', and L. montevidensis (Spreng. ) Briq. (Verbanaceae). Surveys on three Lantana plants showed that the distribution of C. chinensis in inflorescences was not related to floral color (partial correlation coefficient was 0.240, P = 0. 147, n = 40), but to the number of Thrips hawiiensis Morgan (partial correlation coefficient was 0.512, P < 0.0001, n = 40) and the flowers per inflorescence (partial correlation coefficient was 0.451, P < 0.0001, n = 40). In a colour preference experiment, no adult C. chinensis attracted to six different colour plates in longan field. The testing results of four-armed olfactometer indicated that adult C. chinensis had a significantly higher preference for L. camara. It was concluded that olfactory stimuli played an important role in searching for plant hosts of C. chinensis. Solid phase microextraction (SPME) and GC-MS were employed to analyze the volatiles compounds of Lantana, and seven same chemical constituents were detected from the volatiles of three Lantana plants inflorescence.
Using text data mining techniques for understanding the p53 gene expression regulatory network

Abstract: To study the relationship between p53 gene and its downstream/target genes in order to understand p53 network, text data mining method is used and noncommercial software written in Perl 5.10 is used to mine the database from PubMed about p53 gene and human gene ontology, and the p53 network is constructed by linkage clustering analysis. Results show that the frequency distribution of the objective gene with the gene ontology of all the text has a certain correlation, which indicates that the proportion of the low-frequency genes is significantly lower than the high-frequency genes in text data mining. This has allowed us to demonstrate that the distributions of genes in the p53 network have a greater relationship with the frequency of the genes, and meanwhile, text size has an important influence on the accuracy of the text data mining.
