當兩個質子以高能對撞時,其中某些夸克和膠子會以幾近正面的角度沖撞並且回彈,產生一對分佈狹窄、背對背的強子噴霧(稱為噴流) ,朝相反方向噴發而出(參見37頁高密度液體的證據) 。The conclusions are as follows : ( 1 ) high - pressure water - atomization can be used to produce a pre - alloyed steel powder with high apparent density, high green strength, size - stability after sintering and low hydrogen - loss content ; ( 2 ) the higher smelting temperature and / or water pressure, the finer particle size of steel powders ; ( 3 ) when the atomization angle holds in a reasonable value ' s range the obtained powder will have a better particle size distribution ; ( 4 ) an optimum atomization technological parameters : liquid steel flux, water pressure and water prick angle was obtained ( 5 ) reduction variables ( temperature, holding time, material - bed ' s thickness and reducing gas flux ) have a significant effect on the particle agglomeration and properties of final powder was given ( 6 ) different alloying methods were developed to modify properties of ferrous powder materials and hence to broaden its applications in ferrous powder metallurgy industry
本文系統研究了水霧化預合金鋼粉生產工藝及合金化方法對鐵基粉末冶金材料性能影響,詳細研究了冶煉、霧化、還原工藝參數對預合金鋼粉化學成份和物理性能影響,並得出如下結論: ( 1 )採用高壓水霧化技術可用於生產高密度、高強度、尺寸穩定性的低氫損含量的水霧化預合金鋼粉。 ( 2 )冶煉溫度越高,高壓水壓力越大,所得生粉顆粒粒度越細。 ( 3 )水錐角調整在一個適當角度范圍內可獲得粒度組成較好的生粉。For this reason, when the particle size and distribution of the final products, their residual water contents, the stacking density and the particle shape must meet the precision standard, the spray drying is one of the most desired technologies
因此,當成品的顆粒大小分佈、殘留水份含量、堆積密度和顆粒形狀必須符合精確的標準時,噴霧乾燥是一道十分理想的工藝。1 whole set of industrialization technology of producing metal powder by atomization
提供低松裝密度高強度霧化銅粉,高品質銅錫10粉及霧化制粉工業化生產技術。Numerical results indicate that sprays have significant influence on explosion suppression, and that the smaller average diameter of particle and the higher spray concentration is, the more obvious the effect is
計算結果揭示了:液霧對爆炸波有明顯的抑制作用,並且液霧密度越大、霧粒直徑越小,對爆炸波的抑制作用越好。With the action of shock, water drops undergo the process of deformation, fragmentation and atomization. the shock is decreased substantially only when density of water drops in air reaches a certain value
研究發現水滴在激波作用下經歷一個變形、破碎和霧化過程,只有水霧密度達到一定值,激波在水霧中的衰減才明顯。It also supports fog, color density, translucency, fluorescence, and other special effects
它也支持霧、顏色密度、半透明度、熒光以及其他特效。Specification for smoke density indicators and recorders
煙霧密度指示器與記錄器規范Moreover, the secondary wall - impingement distance should be properly reduced in order that the bump play a part in the formation of lean mixture with the increase of environmental pressure or density owing to both the increase of air entrainment, momentum losses and the decrease of the spray tip velocity and penetration
而且當壓力或密度較高時,由於噴霧的空氣卷吸量及動量損失增大,貫穿速度降低及貫穿距減小,為使bump發揮作用,應適當減小二次撞壁距離。Retrieves or sets the fog density for pixel or vertex fog used in exponential fog modes
