事故分析

Statistic analysis to the mechanism and failure of bleed out caused by broken corner is made, and the result shows that the main reason of bleed out caused by broken corner is the inhomogeneity of the shell of crystallization and the inhomogeneity of the secondary cooling system which are caused by the processing parameter in the inside of copper pipe and the wear-out in the corner during the service.

结合氯化反应的工程应用，对有机氯化反应过程安全事故的形成原因进行了初步分析，并提出了反应过程安全控制的技术方法。

By this way, it can be seen that the risks of natural disaster and accident can be transferred by construction insurance and that man-caused risks by construction bond. Furthermore, this paper studies the legal problems in the implementation of construction insurance and bond system and the correspondent laws that need to be improved. With reference to construction insurance, it is compulsive to carry out Contractor"s All Risks, Erection All Risks, Employer"s Liability Insurance, Supervisory Engineer/Designer Professional Liability Insurance and Maintenance Insurance. As for construction bond, it is suitable to take the method of surety bond and implement obligatorily Bid Bond, Performance Bond, Employer Payment Bond and Contractor Payment Bond. In addition, this paper analyses the problems in the implementation of construction insurance and bond system in China and presents corresponding solutions. In the end, it provides a method by option price theory to estimate the costs of construction bond.

本文首先借鉴国外工程保险和担保制度，通过工程保险可以有效的转移自然灾害和意外事故风险，通过工程担保转移各种人为风险；其次研究了在我国实行工程保险和担保制度存在的法律问题和需完善的相关法律，提出在工程保险方面，应强制实行建筑工程一切险、安装工程一切险、质量保修保险、设计/监理责任险，在工程担保方面，宜采取保证担保的方式，强制实行投标保证担保、履约保证担保、业主履约保证担保和付款保证担保，分析了在我国实行工程保险和担保制度存在的问题，提出相应对策；最后运用期权价格理论给出了确定工程担保费用的一种方法。

From the point of view of a captain,this paper mainly analyses how to supervise the cargo ship s overfreight,puts forward several problems to the MSA Officers whom should pay attention to,while the Officers check cargo ship s loadline and judge the cargo ship s overfreight,and also recommends a facility means to calculate the cargo ship s draught.

从船长的角度针对货船超载运输如何监管作简要分析，提出海事人员在检查船舶载重线及判断船舶超载时应注意的几个问题，并介绍一种简易计算载重线的方法，以期对货船超载的监管有所帮助，减少海上事故的发生。

After analysis and parison of virtues and hort ings of existing systemsafety evaluation ways, Artificial Neural Network, Artificial Intelligence and Expert System are used to build new system safety evaluation means. System safety evaluation model and intelligent expert system for fault diagnosis based on ANN have been put forth. Development and realization of visual neural network for system safety valuation and fault diagnosis provides new idea for system safety evaluation and accident mode diagnosis.

对已有的系统安全评价技术方法的优缺点进行了分析和对比，继而将神经网络技术、人工智能技术、专家系统应用于开发新的系统安全评价方法，提出了基于人工神经网络的系统安全评价方法和基于神经网络的智能故障诊断专家系统模型，开发了可视化的神经网络系统，为系统安全评价与事故模式诊断提供了新思路。
