摘要
应用 GM(1.1)灰色数列预测模型法,依据八十年代各年度累积病例数资料,作者预测了1991～1995年宁夏大,小煤矿工人中之逐年新发尘肺病例数——依次为374、160、216、231和250。乡镇规模煤窑工人们之预计发病情况,未列入本预测之推算内。
By applicating the method of GM (1.1)grey number-row forecasting mo- del,utilizing data material expressed as yearly accumulative totals during the 1980s,the author forecasts the year occurrences of pneumoconiosis among Ningxia coal miners for year 1991～1995,i.e.374,160,216,231,250, Consecutively.Those mining in mines of township scale are not included in this calculation.
