摘要
通过对北京市1997年以来天然气年供应量关于GDP、年末房屋建筑面积的回归分析,得出线性回归方程,预测天然气年供应量。由建立的管道总长度关于天然气年供应量的一元线性回归方程,预测管网规模。
Based on the regression analysis between annual natural gas supply volume and GDP/ year-end housing construction area since 1997 in Beijing City, the linear regression equation is obtained to predict the annual natural gas supply volume. The scale of pipeline network is predicted by the simple linear regression equation between total pipeline length and annual natural gas supply volume.
