式中ni为CO2还原过程中形成目标气体产物的生成摩尔数速率；v为CO2气体流速为100 mLmin；ppm为产物浓度；vm为摩尔体积此处取24 Lmol 20 ℃1013 kPa。翻译成专业的学术英语

In the equation, ni represents the molar rate of formation of target gas products in the CO2 reduction process, v represents the gas flow rate of CO2, which is 100 mL/min, ppm represents the concentration of the product, and vm represents the molar volume, which is taken as 24 L/mol at 20 ℃ and 101.3 kPa.
