目前池火灾热辐射大小基本使用经验公式进行计算.由于耗资和安全考虑,实验研究基本集中在小尺度火灾上,难以得到大尺度火灾热辐射特性.本文使用工程计算中的常用理论模型,计算了大型池火灾下的热辐射大小.分析了不同距离和高度下的热辐射通量大小,为防火灭火提供理论和实际指导.

This paper expounds the necessity and importance for sealing large-scale hull infiltrated cuttings from the points of economy,fighting environment,task and army's morale,putting forward a set of flow for sealing such cuttings.Considering the limited space in warship,joggled material can be used instead of steel-sheet in large area.Some special materials for packing are suggested including joggled steel-sheet and quick-drying cement for cutting and welding equipments on water or under water,with the characters of small volume,light mass and powerful function.
