文丘里管和喷嘴是催化燃烧热水器的关键组分，实验中对二者进行了优化。
We optimized the other two important components of the catalytic water heater, the venturi pipe and nozzle.
天然气孔板流量计的现场检定，采用以文丘里音速喷嘴作为标准表的传递型校准法。
The on the spot inspection of natural gas orifice meter is adopting the transitivity calibration method taking Venturi nozzle as calibration scale.
由喷嘴所产生的文丘里效应将干粉吸入紊流中，于是提供了快速有效的混合作用。
The venturi effect created by the jets draws the powder into the turbulent stream, providing a rapid and efficient mixing action.
