The research shows that the optimized two-stage atomizing nozzle has a 0.34 m protection diameter and its spray density distribution is uniform . The protection diameter of the two-stage atomizing spray head with multi-nozzle is more than 2 m which is very practical in fire protection .

研究表明。优化设计后两级雾化喷嘴的喷雾保护半径为0.34m， 喷雾密度分布 均匀：具有多喷嘴的两级 雾化 细水雾喷头的喷雾保护半径可以超过2m，在消防领域具有实用价值。
