其中ni为CO2还原过程中形成目标气体产物的生成摩尔数速率；zi为CO2形成产物分子所转移的电子数；F为法拉第常数96485 Cmol；jave为平均电流密度单位为Acm2。翻译成专业的学术英语

其中，ni represents the molar rate of formation of the target gas product in the CO2 reduction process; zi represents the number of electrons transferred per CO2 molecule to form the product; F represents the Faraday constant (96485 C/mol); and jave represents the average current density, measured in A/cm2.
