例句與用法
- Then the paper also study the atomizer structure ( the protrusion of the delivery tube value h ) , atomizing gas pressure p , over - heat temperature of alloy a t , the component of solder alloy and atomizing medium and so on
進(jìn)一步對(duì)霧化器結(jié)構(gòu)(導(dǎo)液管突出高度h ) 、霧化氣體壓力p 、合金過(guò)熱度t 、焊錫合金成份和霧化介質(zhì)進(jìn)行了研究。 - ( 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 )
研究結(jié)果表明： ( 1 )超音速霧化器的氣體流場(chǎng)在導(dǎo)液管下端形成一個(gè)倒渦流錐，在二維空間上呈軸對(duì)稱(chēng)的雙峰分布，負(fù)壓形成于這個(gè)倒渦流錐內(nèi)； ( 2 )修正后的霧化氣體速度公式可以滿(mǎn)足超音速霧化的要求； ( 3 )影響超音速霧化工藝最根本的因素有氣液質(zhì)量流率比( gmr )的大小、霧化氣體流量和倒渦流錐范圍，三個(gè)因素的值越大，對(duì)形成細(xì)粉越有利； ( 4 )在焊錫合金為zhl63a ，霧化介質(zhì)微n _ 2 ，導(dǎo)液管突出高度取h = 6 . 0mm ，霧化氣體壓力取p = 1 . 0mpa ，合金過(guò)熱度取t = 167 ( t = 350 )時(shí)，所制得的粉末在有效霧化率、顆粒球形度、粒度及其離散度三個(gè)方面綜合性能最好。
