| 摘 要： | 介绍了集对分析的基本原理,指出了差异不确定系数i取值的重要性和目前取值方法的不足.在此基础上,考虑集对间的相关程度和分类标准系数,提出了用统计试验方法来确定差异不确定系数i的新途径,给出了i的合理取值.研究结果表明,i的取值与集对间的相关系数、序列变差系数Cv以及分类标准系数等因素有紧密关系.研究成果对推动SPA在水文水资源中的应用具有重要的意义. |

| Abstract: | The principle of set pair analysis (SPA) was introduced, the importantance of the value of i in SPA was pointed out, and the drawbacks of general approaches to the value of i was explained. Based on statistical test, a new approach to determine the reasonable value of i was precented attempted combined related coefficient of the set pair with kind coefficient. The results showed that the value of i in SPA is related to pair analysis to related coefficient of the set pair, variation coefficient and kind coefficient. The results about SPA should be helpful to hydrology and water resources.The reasonable outcome may be helpful in the field of hydrology and water resources. |
| Keywords: | set pair analysis relational degree the value of i related coefficient |
