摘　　要：应用粗糙集理论研究了薄膜蒸发器历史数据不确定影响下的产量预测问题。结合0.4 m2薄膜蒸发器试验数据,应用粗糙集理论,给出了从数据准备、数据挖掘、挖掘结果的解释与评估到最终产量预测结果的完整预测过程。结果表明:应用粗糙集理论得到的薄膜蒸发器产量预测结果与工程实践吻合较好。The output forecasting influenced by uncertain history -data of film evaporators is studied by Rough Set theory. The complete forecasting process including the explaination and evaluation of datapreparing,data- excavating and excavating results, and the final output forecasting results is given by applying Rough Set theory and combining with the experimental data of 0.4 m^2 film evaporators. The results show that the output forecasting results of film evaporators achieved by applying Rough Set can coincide with those of the practical engineering production well.
