A proper spray patternis elongated. This isachieved by squeezing the metal on two opposing sides ofthe circular opening. The more it is squeezed, the flatter the fan, hence the widerthe spray pattern.
一个正常喷涂后所应形成的图形是细长方形，这是涂料对金属片上的两个位置相对的圆孔施压所形成的，施压越大，扇形面越平，因此喷涂出的图形会越宽。
This system distributes both the fan and atomizing air equally, providing a more uniform spray pattern.
此系统同等分布风扇和雾化空气，可以提供更均匀的喷雾类型。
Flat fan nozzles were found to provide the most uniform spray pattern under many pressure conditions with a coefficient of variation less than 15%.
实验研究发现，扇形喷嘴可以提供最为均匀的喷雾效率，其变化系数小于15%。
