利用回归方程对沼气发生量的预测

示了沼气发生量与污水二级处理量和污泥沉淀量存在有显著的线性关系，关建立了相应的二元线性回归方程，同时利用标准回归系数判定污泥沉淀量是影响沼气发生量的主要因素。

Predict the Methane Output by Establishing the Regressive Equation

This articletriesto show that there is the linear relations among methane output,the quantity of secondary wastewater treatment and the quantity of setting sludge.At the same time it establishes the dual linear regressive equation relevantly.After using the standard regressive coefficient,it reveals that the quantity of setting sludge is the main influential factor for the methane output.So we can use this method to predict the methane output through the quantity of wastewater and the quantity of setting sludge.
