例句與用法

1. 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
   進一步對霧化器結構(導液管突出高度h ) 、霧化氣體壓力p 、合金過熱度t 、焊錫合金成份和霧化介質進行了研究。
2. ( 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 )
   研究結果表明： ( 1 )超音速霧化器的氣體流場在導液管下端形成一個倒渦流錐，在二維空間上呈軸對稱的雙峰分布，負壓形成于這個倒渦流錐內； ( 2 )修正后的霧化氣體速度公式可以滿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量流率比( gmr )的大小、霧化氣體流量和倒渦流錐范圍，三個因素的值越大，對形成細粉越有利； ( 4 )在焊錫合金為zhl63a ，霧化介質微n _ 2 ，導液管突出高度取h = 6 . 0mm ，霧化氣體壓力取p = 1 . 0mpa ，合金過熱度取t = 167 ( t = 350 )時，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方面綜合性能最好。
