摘要
给出了同征物元体的概念， 使诸多同征物元表示简洁． 提出了可拓评价方法的级别变量特征值概念， 使评价结果更加合理． 针对某种实际问题给出了由简单关联函数确定权重的新方法， 该方法简单易行．
The concept of matter\|element matrix with the same characteristics is introduced and the concept of level variable characteristic value of extension assessment method is suggested.The method for determination of extension weights by using simple dependent function is proposed.On these bases,the extension assessment method is firstly applied to stability classification of surrounding rocks.
