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%。
Flat fan nozzles were found to provide the most uniform spray pattern under many pressure conditions with a coefficient of variation less than 15%.
嗨。马克，你的自动化喷雾器效率真高呀。
用喷淋加湿取代蒸汽喷雾是目前在湿热交变实验箱中推广的一种新方法，它具有体积小、耗能低、效率高、操作方便等优点。
We use spraying damping instead of steam atomizing, which is a new spread method. It have advantages of small dimension, low power consumption, high efficiency, convenient operating and so on.
