multilevel system

At present, several methods such as TNT equivalence method, TNO method, British gas VCE method, Shell method and Multi-energy method are used to evaluate the above parameters, in which the multi-energy method is considered as a much more advanced model for vapor cloud explosion prediction.

以多能法中距离 -超压关系图为例 ,介绍了一种运用前馈多层感知器网络对现行多能法中查图步骤进行改进的方法。

On the basis of analyzing the hazardous characteristic and the characteristic of vapor cloud explosion accident of liquefied petroleum gas,two methods TNT equivalent method and TNO multi-energy method are used to calculate the consequence of vapor cloud explosion accident in LPG storage tank,the radius of death,sev.

本文在分析液化石油气的危险特性和发生蒸气云爆炸事故特点的基础上,用两种常用的蒸气云爆炸后果模拟方法TNT当量法和TNO多能法对液化石油气储罐发生蒸气云爆炸的后果进行计算,分别得到死亡、重伤、轻伤和财产损失半径。
