组分方程 meaning in Chinese

composition equation

In the model the film thickness in the passage was obtained at first using two phase flow theory ; then , similar analysis solution of concentration distribution of the pollutant in liquid phase and biofilm was obtained through mass component equation of pollutant in gas - liquid phases combined with the biochemical kinetic equation of mass transfer in biofilm and dismission of oxygen limited ; at last , the distribution of pollutant along the filter height and the waste gas purification efficiency were obtained
该模型首先运用两相流理论获得了通道内液膜厚度，然后通过污染物在气相、液相的质量组分方程，结合生物膜内的传质与不?虑氧限制的生化反应动力学方程，获得了污染物在液相和生物膜中浓度分布的近似分析解，最终得到污染物在气相中沿塔高的浓度分布及废气净化效率。
