irreversible reaction meaning in Chinese

不可过反应
不可逆反应

Subsequently the reduced mechanism is used for three - dimensional numerical calculation in the flow solver technology of star - cd . 2 . different from the one - step irreversible reaction , a multi - step reaction combined time scale model is developed to the solve combustion - turbulence interaction firstly
2考虑化学反应和湍流的相互作用，建立了有别于普遍采用的基于单步不可逆反应的混合湍流反应(时间)速率模型的新模型，即多步反应混合湍流反应(时间)速率模型。
