通过对撞针型结构、离心式结构、较高的喷水压力、较小的喷嘴孔径、喷水初温及待加湿空气初状态对雾化加湿效果的作用原理的重点分析，得到：撞针型高压小孔径离心式喷嘴具有较大的空气涡与雾化角，喷出的液体流速高、液滴小、水与空气传热传质速率高，撞针型结构提高了雾化加湿效率，高压小孔径的特点为雾化加湿提供了较大的能量，而喷水初温的升高会减小水的粘性力和表面张力，从而优。
6) adjustment by water spraying
喷水调节

【诗文】：
东风卷帘＊幕，时物又新奇。桃花院落，小桥流水柳依依。正是清明天气，茅草池塘鲜丽，何处不相宜。紫燕添新垒，小雨洒芳菲。老生涯，沽酒杖，钓鱼矶。江湖一样，几声鸥鹭夕阳微。百岁光阴石火，万叠云山烟锁，回首顿忘机。蝶梦松窗下，高卧碧云溪。
