摘要:

目前，失效后果评价中计算火球热辐射距离时存在多种假设，制约了结果的准确性。采用将火球分成无数小实体，对某距离目标物接受的热辐射求和，并考虑了火球的高度影响，力求得到准确的结果。对结果进行回归，提出针对甲烷及天然气用于一定可燃物质量范围的火球热辐射模型。

Abstract:

Currently,in the field of assessment of failure consequence,the calculation accuracy of impact area of fireball's thermal radiation is limited by some ungrounded assumptions to some extent.In this article,fire ball is divided in numerous small parts,from
