指出凭估定设计的底部供料均布喷孔的传统喷头所存在的固有缺点，如喷洒密度呈尖峰状分布及部分喷洒线交错等。作者根据喷头及喷洒状况设计等密度喷头，并给出了各种规格喷头的喷洒密度分布曲线．德州化肥厂１３万吨／年尿素使用此种喷头喷洒密度分布曲线平坦，粒径在１．５～２．５ｍｍ的接近９０％，颗粒强度也很好．
He pointed out the inherent shortcomings of the traditional nozzles with the bottom-supplied uniform spray holes, such as sprinkling density sprinkling and partial spray lines staggered. According to the nozzle and spray conditions, the design of the nozzle density and other specifications, and gives a variety of nozzle spray density distribution curve. Texas Chemical Fertilizer Plant 130,000 tons / year of urea spray density distribution using this nozzle flat, particle size of 1.5 to 2.5mm in the nearly 90%, particle strength is also very good.
