| 摘 要： | 应用灰关联分析法和灰色建模理论对江苏省东辛农场的大中型拖拉机完好率进行系统研究， 以 １９９１～１９９７ 年的统计数据为基础， 建立了若干个大中型拖拉机完好率的灰色预测模型。由模型分析可见， 农机新度系数、大中型拖拉机的新旧结构比例是影响大中型拖拉机完好率的两大重要因素。

| Abstract: | The intact rate of large medium tractors in Dongxing State Farm of Jiangsu Province was systematically researched by grey correlative analysis and grey modelling theory.Based on the statistic data from 1991 to 1997,a couple of grey forecast models for intact rate was established.The analysis on models showed that newness coefficient of agricultural machinery,proportion of new and old tractors are two important factors affecting on the intact rate of large medium tractors. |
