安全

In recent years, sever security accidents frequently arise in China, especially the colliery industry, of which serious posture exists. To protect the secure of producing and managing more efficiently, and to punish those who produce and manage with insecure elements, the Amendatory Act 6 makes amendments in this field. However, a imprecisely prescription would cause a inaccurately applying.

近几年，我国重特大安全事故频发，尤其是矿山行业的安全生产形势非常严峻，为了更有效地维护生产经营的安全，惩治那些不重视对安全生产设施和安全生产条件进行投入、建设、管理和维护的行为，《刑法修正案》对重大劳动安全事故罪进行了修改，但是修改后的条文在犯罪构成要件的表述上不明确，在司法上不能得到准确适用。

近几年，我国重特大安全事故频发，尤其是煤矿行业的安全生产形势非常严峻，为了更有效地维护生产经营的安全，惩治那些不重视对安全生产设施和安全生产条件进行投入、建设、管理和维护的行为，《刑法修正案》对重大劳动安全事故罪进行了修改，但是修改后的条文在犯罪构成要件的表述上不明确，在司法上不能得到准确适用。

It is known that the security defense intensity of the information system depends on the weakest part of Maginot line. If there is no appropriate security architecture as a guide, it is difficult for the various security components in the information system to coordinate with each other and to work in order. Then, it often appears the "safety shortcomings" phenomenon, resulting in the vulnerability in the security and all the protection efforts in the information system are in vain. 2 Trusted computing and security mechanisms come apart.

众所周知，信息系统的安全防护强度取决于"马奇诺防线"中最为薄弱的环节，如果没有合理的安全体系结构作为指导，信息系统中各安全部件就难以相互协调、有序工作，就很容易出现"安全短板"现象，从而导致信息系统安全防护不堪一击，所有的努力功亏一篑。2可信计算和安全机制相脱节。

Based on the example of shahe reservoir, the text makes an analysis on circulation, management and environment and social economy development condition of the surrounding ecosystem. Then, the author carries on inquisition, data analysis and summary and makes calculation and demonstration of the safe stability of the dam ,and discusses the risking obviation and reinforcing technique. Finally, based on the existing research of sustainable development, experts" opinions and Mathematical Statistics analysis, the author brought forward an indication system suitable for reservoirs" sustainable development This system is made up of 4 first class indexes, 13 second class indexes, 38 foundational indexes. The 4 first class indexes are the dam safety evaluating index, the management index of reservoirs, the water ecosystem system stability index, the reservoirs construction effect index. The 13 second class indexes are the construction quality evaluating index, the dam running and management evaluating index, the flood control standard recheck index, the structure safety evaluating index, the anti- earthquake evaluating index, seepage safety evaluation index sign, the metal structure safety evaluating index, the engineering facility index, the management index, the water ecosystem system stability index, engineering effect index, the economic development index, the society development index.

本文以沙河水库为例，对其运行、管理及周围生态环境和社会经济发展状况进行调查，并将调查资料进行分析、归纳、总结；然后对水库大坝的安全稳定情况作出了简要的计算和论证，并讨论了水库的主要除险加固技术；最后在总结现有可持续发展研究的基础上，征集专家的意见，进行数理统计分析，提出了由4个一级指标、13个二级指标、38个基层指标组成的一套适合该水库可持续发展的指标体系。4个一级指标分别为：水库大坝运行安全综合评价指标、水库管理指标、水资源生态系统稳定性指标、水库建设效应指标；13个二级指标分别为：工程质量评价指标、大坝运行管理评价指标、防洪标准复核指标、结构安全评价指标、抗震安全评价指标、渗流安全评价指标、金属结构安全评价指标、工程设施指标、管理指标、水资源生态系统稳定性指标、工程效应指标、经济发展指标、社会发展指标。

The general objective of the thesis is to develop a language-based foundational theory of security for mobile and distributed systems, and this thesis focus on the following four interrelated aspects. Firstly, aiming at the access control, a type system with security levels is proposed and the Subject Reduction Theorem under labelled transition system is proved.

针对安全模型面临的困难与挑战，本研究从分析移动系统安全的实质出发，对系统安全进行高度的抽象，使用π-演算及其类型系统为理论工具为分布式系统安全建模，提出对安全模型的定义、规范、分析与实现都借助程序语言的理论、技术与方法的一体化路线，研究基于程序设计语言的安全模型。

Can think that road traffic safe program is government and its function department is , make the personal casualties of road traffic accident lose with property in program issue fall to the goal intended, determine in the traffic safe measure and action and its enforcement that person, vehicle, road and environment should adopt with the aspects such as management sequential, it is different levels people's government and its function department science develop the road traffic at will sexual major basis and important means of blindness of working and preventing road traffic safely working decision safely , it is strategy and the direction of road traffic safe development, have the scientificness of guaranteeing road traffic safe management and avoid decision fault before Zhan sexual role, have important strategic meaning for preventing road traffic accident.

可以认为，道路交通安全规划是政府及其职能部门为使道路交通事故的人员伤亡和财产损失在规划期内降至预定的目标，确定的在人、车、路、环境和管理等方面应采取的交通安全措施和行动及其实施时序，是各级人民政府及其职能部门科学开展道路交通安全工作、防止道路交通安全工作决策的随意性和盲目性的主要依据和重要手段，是道路交通安全发展的方向与战略，具有保证道路交通安全管理的科学性及避免决策失误的前瞻性作用，对预防道路交通事故具有重要的战略意义。
