In the aspect of the recognition, the recognition of the essence and ultimate purpose of the ideological and politucal education, the human essence and psychological development are the key points. As to the mechanism, the most important is to form the thoro and omni-directional mechanism of the particification of the whole staff, at the same time, to develop the new resources of the ideological and political education, to improve the qualities and abilities of the educators, especially their scientific, humanist and innovative spirits.

在思想认识方面，对思想政治教育本质，根本目的认识，对人的本质和心理发展的认识是关键；在机制保障方面，最重要的是形成全员育人，全程、全方位育人的机制，与此同时，要不断开发思想政治教育的新资源，不断提高教育者的素质和能力，特别是他们的科学精神、人文精神和创新精神。

For the safety of LAN and using firewall thriftily,the authors analyze the architecture of Netfilter in Linux2.4 kernel.Then the authors implement the firewall system based on embedded Linux OS,which has basic functions as Package Filtration,URL filtration,NAT and log.And,the firewall system integrates with DMZ which establishes a buffer zone between Internet and Intranet to make the Intranet safer,and connection tracking which maintains a table for connection track in order to get the more safer than package filtration.

为了构建安全可靠的网络，同时降低使用防火墙的成本，对Linux2.4内核防火墙结构Netfilter的实现机制进行了深入的研究和分析，并利用该机制设计实现了一个嵌入式Linux防火墙系统，该防火墙实现完善了包过滤、URL过滤、NAT和日志等防火墙基本功能，同时集成了非军事区，为Internet和Intranet之间建立了缓冲地带，以保证Intranet的安全。

(1)SCG is a sensitive, simple and economic method in evaluating the cytotoxicity of SM in toxication and the degree of intoxication, and with good prospects in early diagnasis;(2)The cytotoxicity caused by the elevation of NO induced by the NOS activity after intoxication might be one of the mechanisms of SM intoxication;(3)Apoptosis participates in the process of SM intoxication also might be one of the mechanisms of SM intoxication.

(1)SCG法敏感、经济、简便，可用于硫芥中毒细胞毒性、中毒程度的评价，在早期诊断上有良好的应用前景；（2）中毒后因NOS的活性升高导致NO的升高而产生细胞毒作用可能是硫芥的中毒机制之一；（3）细胞凋亡参与了硫芥的中毒过程，亦可能是其中毒机制之一。

By using multi-dimensional nuclear magnetic resonance method we have studied the folding mechanism of staphylococcal nuclease in vitro; the tertiary interactions for folding of SNase fragments into native-like conformation; the interaction between SNase N- and C-terminal subunits; the relationship of enzyme activity with folding and dynamic states of SNase; the structural properties of enzyme protein while exert its function. We have studied the internal motions of thermophilic Archaea protein Ssh10b and mechanism of its heat-resistance using the NMR 1H-15N relaxation and H/D exchange methods. We have determined the 3D solution structure of human translationally controlled tumor protein TCTP and the Ca2+-binding site; determined the 3D crystal structure of human mitoNEET, a novel protein from distinct groups of iron-sulfur proteins; determined the 3D solution structure of a novel chromatin protein Cren7. Determination of SNase-DNA and Archaea protein-DNA complex structures are in progress.
