bubble variation

基本解釋

This paper reports some experimental results on variation of voidage in bed materials, bubble size and bubble rising velocity etc along the height of the bed.
本文介紹了流化床中床料空隙率，氣泡尺寸，氣泡上升速度沿床高變化的試驗結(jié)果，提出了相應(yīng)的無因次關(guān)聯(lián)式。
The result shows that the bubble is an important factor influencing coal separation, and the variation of its volume fraction is closely related to the variation of density of ADMFB.
結(jié)果表明：氣泡是影響分選精度的重要因素，其體積分率的變化與床層密度波動密切相關(guān)。
The hydrogen bubble technique was used to visualize the development and variation of a backward facing step laminar separation flow, which covered basic flow and its unsteady control.
應(yīng)用氫泡流動顯示技術(shù)研究了后向臺階層流邊界層分離、再附整個過程中流動結(jié)構(gòu)的發(fā)展變化。
