摘要
为完善事故致因理论体系,论述并解析能量流系统定义,分析系统能量流流向,构建基于能量流系统的事故致因概念模型,并从能量串发、发散、集中和混合四方面解析其内涵。对能量流的聚集、耦合、转换、释放,以及意外释放能量的防控效果、破坏强度和伤害程度等进行数学描述。基于此,构建基于能量流系统的事故预防概念模型,并提炼减灾措施。研究结果明晰了事故发生的物理本质,从能量流系统的视角为事故致因的定量分析或半定量半定性分析提供理论参考,并可为事故预防与控制提供理论指导。
To improve the accident causing theory system , the definition of energy flow system was illustrated and analyzed , and the flow direction of systemic energy flow was analyzed .A conceptual model of accident causing based on energy flow system was constructed , and its connotation was analyzed from four aspects including energy string , energy radiation , energy gathering and energy mixing .The mathematical descriptions on gathering , coupling , transformation and release of energy flow, and the prevention and control effect , damage strength and injury degree of unexpected releasing energy were carried out.On this basis, a conceptual model of accident prevention based on energy flow system was constructed , and the disaster reduction measures were extracted .The results clarify the physical nature of accidents occurrence , it can provide theoretical reference for quantitative analysis or semi-quantitative analysis on accident causing from the perspective of energy flow sys -tem, and provide theoretical guidance for accident prevention and control .
