土工合成材料试验工作中的决策分析方法和数据再现性

土工合成材料试验指标值与它应用效果密切相关。指标值需要应用决策分析的方法最终确定。而粗集理论则能为它提供一种较好的决策分析方法，对日前试验指标值间进行相关或比较及一致性程度的统计分析时，要先考察其来源和试验数据的再现性是否符合要求。

Decisive Analysises and Data Reproducibility in Trial of Synthetic Materials

The trial indexes for soil engineering synthetic materials are closely correlative with their applied effect. The indexes need determination by decisive analysises. While Riugh sets could offer a better decisive analysises. When the correlative and identical statistic analysis of the trial indexes at present is performed,it must be made to first investigate if their sources and reproducibility of trial data conform to requirements.
