Thirdly, it collect the ship mechanical accidents of the main Chinese shipping company ,and then sorts them out as four items: equipmentname, typical trouble, monitoring parameters, consequence; uncovers the internal relation among man,machine,circumstance and management, establishes a relation database between condition monitoring and typical trouble for the engine-room equipments ; refering to the SMSC-2000 marine engine-room simulator in Shanghai Maritime University, it divides the engine-room system into eight subsystems, designs the monitoring interfaces which is marked with the monitoring parameters, detects the running engine-room machine by use of trouble analysis and information syncretizing, and builds up the condition monitoring system of engine-room machines.

其次，对近十几年来的国内主要航运企业中的重大船舶机损事故搜集，按设备名称、典型故障、监测参数和后果进行整理、分析和总结；揭示了船舶机损事故中人、机、环境和管理之间的内在联系：以我院的轮机模拟器SMSC-2000参照，把船舶机舱各设备划分为8大系统，确定了标注有监测参数的各系统简图，并运用信息融合和故障诊断技术对机舱重要设备的运行状态进行监测，建立起机舱设备的运行监测系统。再次，提出了以人、机、环境和管理四大安全要素为评估指标，给出了四者间的权重系数计算方法，提出了线性加权综合模型来最终对机舱设备进行安全评估，得出安全等级，指导船舶管理人员进行管理。

The idea is presented to convert sequences and consequences of event tree into their corresponding fault trees, which is used in the event tree analysis combined with fault trees. Then, a sequence analysis strategy based on cut sets matching is introduced, and the event tree fast analysis algorithm is implemented.

通过分析爆炸特性、分类和爆炸物质危险特性，以及爆炸的危害作用，指出了爆炸灾害事故处置的难点问题，对处置爆炸灾害事故需要的专业理论、应掌握的技战术要点、心理训练和灭火救援准备进行了阐述。

The analytic results obtained from the PCT evaluations revealed that the most limiting accident was the case with a break at the Main Steamline Outside Containment. Its PCT was 1289.15 ℉, which is much below the upper temperature limit of 2200℉ set by the nuclear regulatory authority. The most limiting accident for the minimum water level measured outside the core shroud is the case with a break at the High Pressure Core Flooder Line, the minimum water level drops to 18.4 ft. For this case, even though the water level has dropped to 11.6 ft below the top of the active fuel, the reactor core was still completely covered by the two-phase water.

分析结果显示，对燃料护套最高温度而言，最严重之事故为围阻体外主蒸汽管路破口，其燃料护套最高温度为1289.15 ℉，此温度远在法规10CFR50.46所定之限值 2200 ℉以下；对反应炉最低水位而言，则最严重之事故为高压注水系统管路破口，反应炉降水区最低水位降至18.4 ft，约在有效燃料顶部以下11.6 ft，然而炉心内部仍为双相饱和流体所完全覆盖。
