【摘要】 把GM(1,1)模型求解中的B矩阵进行了改进,以此利用GM(1,1)模型针对大气中的臭氧含量进行分析和预测.根据预测误差分析,预测结果跟实际情况吻合很好,预测结果见文中表5;误差情况见文中表6,相对误差在6%以内,说明利用改进的GM(1,1)模型对大气中的臭氧含量进行预测效果很好。更多还原

【Abstract】 This paper Improves the B matrix of in the GM(1,1) modeling.It analyses and forecasts the Ozone content of the atmosphere,and the forecasts in the table 5 is very accurate,based on the table 6 that it content the relative error of the forecasts and the relative error Is smaller than 6%,so the improvement GM(1,1) modeling is very effective for the forecasting the ozone content of the atmosphere.更多还原
