From the grey model of the gross value of industrial output of Anshan over the years, we can forecast the gross value of industrial output of1990, the forecasting error is10.99%. 通过建立鞍山市历年工业总产值全数据的灰色模型,较准确地预测出鞍山市1990年的工业总产值,其预测误差为10.99%。
By 1949, the gross domestic value of industrial output accounted for 30% of the gross output value of industry and agriculture, with heavy industry a share of 7.9%. 到1949年,国内工业总产值占到工农业总产值的30%,其中重工业比重为7.9%。
The increased output value through agricultural technical progress till the end of the20th century is expected to60-70 percent of the gross agricultural output value. 农技进步对我国农业总产值贡献到本世纪末欲达60~70%左右,实现农业总产值规划目标技术进步是关键。
Model analysis showed that during 1996 2000, the average annual increase of GNP of Jiangxi is about 4 727 billion yuan, that of gross value of industrial output is 8 billion yuan and that of gross value of agricultural output is 2 billion yuan. 通过建模分析,在1996~2000年间,平均每年给江西国民生产总值增长约47.27亿元,工业总产值约80亿元,农业总产值约20亿元;
