灰色米质指数及其在稻米质量评判中的应用

用加权关联度作为灰色米质指数，在介绍其求解原理和方法基础上，对灰色米质指数在稻米品质综合评判和分级中的应用进行了初步探讨。通过对6个籼稻品种综合米质的评判结果表明，如参考数列构造合理，权重系数分配得当，依据灰色米质指数对稻米品质进行综合评判和分级是可行的；虚拟的理想参考数列所建立的评判模型，使评判的适用性得到增强。

Grey rice quality index and its application in the evaluation of rice quality

The weighted correlation measure was used as the grey rice quality index. On the basis of introducing the theory and method of calculation, some primary researches on how the grey rice quality index is applied to evaluating and classifying the rice quality were conducted. The research of comprehensive evaluation of six kinds of rice shows that it is feasible to apply the grey rice quality index to comprehensive evaluation and classification of the rice quality if the index is reasonable and the weighted index is allocated appropriately. The judgment model set up by the subjunctive ideal reference numeral increases the adaptability of the judgment execution.
