per unit area concentration

基本解釋

It was found that the oxygen concentration on carbon black surface is proportional to the ozone supplied per unit area of carbon black surface.
研究表明，碳黑的表麪含氧量與提供給單位碳黑表麪的臭氧量成正比。
The analysis includes the concentration ratio at the base of a GCL, advective and diffusive mass flux, and total accumulated contaminant mass through the liner per unit area.
從襯墊底部濃度比、對流和擴散通量、汙染物累積運移量等方麪，對汙染物在GCL中的運移進(jìn)行了計算。
The culture model has salient features in high culture concentration, being conveniently controlled, high food conversion rate, high output per unit area, disease prevention and non - pollution.
