To resolve those problems, the nature of safety is expatiated by comparing the differences between safety and reliability, security, which would facilitate us to design some novel safety mechanisms. Based on multilevel safeguard mechanisms, the safety technologies of distributed mission real time system is deeply, systematically researched in this dissertation, some main works and contributiveness including:1 To improve safety of complex mission critical real time system by dividing and ruling way, the whole system usually is divided into few small and simple subsystems with different criticality.

并以多级防危机制为核心，对分布式任务关键实时系统的防危技术进行了系统、深入地理论研究和实验，主要的贡献与创新之处包括：在分析现有应用级防危机制不足之处的基础上，基于多级关键度划分的思想，提出了集成式的多级防危机制，其中重点研究了支持该机制的多级关键度访问控制规则，其目的是防止低关键度子系统中的设计缺陷破坏高关键度子系统的防危性，同时研究了基于反射技术的规则执行。

In ACC, NGF,TrkA and p75 mainly existed in cells of duct-like, cribriform and mass-like structures.According to the optical density scanning of immunohistochemistric stain of NGF and TrkA in salivary gland and tumor tissues and quantification analysis, it was shown that the average optical density of NGF and TrkA increased in order of salivary gland tissues around neoplasm, mucoepidermiod carcinoma, and adenoid cystic carcinoma.

2叫 吉林大学硕士学位论文通过对NGF和TrkA在涎腺组织和涎腺肿瘤中的免疫组织化学染色结果进行光密度扫描，对所测平均光密度定量分析，结果显示：NGF和TrkA平均光密度值按照肿瘤周围涎腺组织、豁液表皮样癌和腺样囊性癌依次升高，统计学分析在各组间均有极显著差异(P.01)，表明NGF和TrkA通过自分泌机制调控涎腺腺样囊性癌和豁液表皮样癌的生长与增殖，通过旁分泌机制参与涎腺腺样囊性癌向神经周围的浸润。

Crocin exerts both in vitro and in vivo anti-cancer effect on TCCB T24 cell line. The mechanisms may change tumour cell cycle and induce tumour cell apoptosis by down-regulating the expression of Bcl-2, Survivin, Cyclin D1 and up-regulating the expression of Bax.

Crocin对人膀胱癌T24细胞株的体内外增殖均具有良好的抑制作用，其机制可能是改变细胞周期分布和诱导细胞凋亡，作用机制与下调Bcl-2， survivin，Cyclin D1基因表达和上调Bax的基因表达有关。

For example, cyclobutane pyrimidine dimers and pyrimidine-(6-4)-pyrimidones photoproducts [(6-4) PPs] etc. In general, the normal person can repair damaged DNA by reconstructive mechanism of DNA, what is called nucleotide excision repair.

一般正常人，可利用所谓的nucleotide excision repair之DNA修复机制，修补损伤的DNA，但如果此修复机制因基因突变，造成其功能性丧失，无法修复DNA时，即形成所谓的著色性乾皮病。

Analyzes how to improve the method of reliability based multi - tie distributed application system, Presents datable eormection pooling, object tx3oling, fault model and dynamic load balancing based on briefcase and negative feedback model, Applies DCOM/COM ＋ middleware in the models, and gives a project instance on the theory.

通过对提高分布式多层应用系统可靠性方法的分析，进而提出了数据库连接池、对象池、公文包机制容错模型和基于负反馈机制的动态负载平衡模型等几种可靠性关键技术，并结合DCOM／COM＋中间件技术和具体实例说明了这些技术的应用。

On the investigation, main factors impacting success of A company product development management is product development progress, product development flow management, process monitor, organization structure, product development quality , product development cost, management mechanism of product development project, resource match, and establishes ISM of factors, the degree of base factors impacting the success of product development management decreasingly is product development management flow, management mechanism of product development project, organization structure of product development management with AHP method.

其次，借鉴业界经验并通过高层领导小组研究讨论，确定了A公司产品开发管理效率的评价指标，对评价指标采用逐对比较法判断指标的相对重要性；通过调查得出影响A公司产品开发管理效率的八个主要因素，它们分别是产品开发进度、产品开发流程、过程监控力度、组织结构、产品开发的质量、产品开发的成本、产品开发项目的管理机制和资源匹配的齐全度。建立了影响因素的解释结构模型，运用层次分析法得出影响产品开发管理效率的根本因素，并按影响程度，由大到小排序为产品开发管理的流程、产品开发项目的管理机制、产品开发管理的组织结构。

Demandable market-oriented system will replace fractional planned system,competitive system will replace equalitarianis m,economic system,which is public ownership system as leading role and diversesectors of the economy will be developed with the public ownerˉship system,will replace the unitarily system of the ownership.

以需求为导向的市场机制必将代替传统的计划体制，以优胜劣汰为本质特征的竞争机制必将代替平均主义，以公有制为主体，多种经济成份共同发展的经济制度必将代替单一的所有制。

Methods: 1 To establish rat AS models, rats in the experiment were divided intofive groups: normal control group, hyperlipidemia group (fed with high-cholesterol diet), hyperlipidemia + vitaminDS group, hyperlipidemia + vitamin D3 + endothelium denudate group,losartan group (hyperlipidemia +vitamin D3 + endothelium denudate group treated with losartan).

本实验从AS的主要的三种发病机制出发，建立和比较了三种建立大鼠AS模型的方法；同时以该模型为基础，探讨了MMP-9/TIMP-1的动态平衡与AS的关系；也研究了血管组织及血浆血管紧张素H水平与AS的关系；探讨了AngⅡ 1型受体拮抗剂氯沙坦是否具有抗AS作用，以及机制如何。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
