摘要
针对近年来华北地区天然气需求量增加,而气源供给逐渐紧缺的现状,应用线性回归的方法对历史数据进行了分析,对超出供需平衡的年份所对应的数据进行了线性规划和合理的分配,使之在短期内能够达到供需平衡的要求。建立了微分方程,以预测天然气需求量经调整后在短期内的发展状况。
In allusion to the increase of natural gas demand and the decrease of natural gas supply in recent years,an analysis on historical data is carried out with linear regression method to linearly plan and rationally distribute the data which is correspondent to the years with unbalance supply and demand of natural gas in order to meet the needs of supply and demand of natural gas in a short-term. In the paper, differential equations are established to predict the calculated supply and demand of natural gas in short-term periods.
