1. The
injectant is air in the case of density ratio of 1. 0, or heterogeneous gas in the case of density ratio of 1. 5 and 2, 0.
密度比为1时射流为空气，密度比为1。5和2。0射流为异质气体，射流与主流的夹角为35°，孔间距为3倍的气膜孔直径。
2. An investigation was conducted to explore the influence of density ratio and velocity ratio of mainstream/
injectant upon the cooling effect of flat plane film using heat-mass transfer analogy.
采用传热传质类比的方法研究主射流密度差和速度比对单排孔平板气膜冷却效率的影响。
3. Monitoring the content of the surfactant in the produced liquid from EOR test area is an important indication for understanding the direction of
injectant and the displacement characteristics .
