| 为了提高同异分析理论在品种评价中的准确性，针对品种区域试验同异分析中不确定系数i取值难的问题，探讨了用灰色关联度代替同异联系度求解同异分析中不确定系数i的方法。可通过确定各性状的理想值、计算被评价品种中各性状χlk与理想性状集中各对应性状值χok的同一度、确定各性状的权重向量、计算各品种同一度和差异度状态与最优数列的灰色关联度等步骤，最终求出i值。应用结果表明，上述求解方法是可行的，对于进一步完善同异理论具有重要意义。 |

| In order to overcome a difficulty for uncertain coefficient i not to be determined easily in similarity difference analysis for variety regional test,A method was proposed by substituting grey relational degree for similarity difference connection degree.The method and steps of similarity difference analysis were introduced by determining i value,a living application example was given.The result showed that the method above mentioned was feasible,and had an important meaning for further improving and perfecting the theory of similarity difference. |
