雾化率 meaning in English

condensation rate

( 3 ) the most principal factors that influence the supersonic atomization process include the flow ratio of the gas - liquid metal ( gmr ) value , the flow of atomizing of gas and the range of the inverse vortex taper . the more of the value of three factors , the more advantage they are for the atomization and the more fine the powders are . ( 4 ) the produced powders are the best in efficient atomization efficiency , particle diameter , particle shape and dispersion when the solder alloy is zhl63a , atomizing medium is n2 , the protrusion h = 6 . 0mm , atomizing gas pressure p = 100mpa , over - heat temperature t = 167 ( t = 350 )
研究结果表明： ( 1 )超音速雾化器的气体流场在导液管下端形成一个倒涡流锥，在二维空间上呈轴对称的双峰分布，负压形成于这个倒涡流锥内； ( 2 )修正后的雾化气体速度公式可以满足超音速雾化的要求； ( 3 )影响超音速雾化工艺最根本的因素有气液质量流率比( gmr )的大小、雾化气体流量和倒涡流锥范围，三个因素的值越大，对形成细粉越有利； ( 4 )在焊锡合金为zhl63a ，雾化介质微n _ 2 ，导液管突出高度取h = 6 . 0mm ，雾化气体压力取p = 1 . 0mpa ，合金过热度取t = 167 ( t = 350 )时，所制得的粉末在有效雾化率、颗粒球形度、粒度及其离散度三个方面综合性能最好。
