提出3种变长CD-CAT终止规则，在DINA模型、4种属性层级结构下，采用ED选题策略，讨论提出的3种方法与常用CD-CAT终止规则在7个评价指标上的优劣。研究结果显示：新的3种方法较常用终止规则有其自身优势。

Three new variable-length termination rules in cognitive diagnosis computerized adaptive testing is pro-posed. Results of the new methods with pre-existing methods were compared under seven evaluation indexes,using the deterministic inputs,noisy“and”gate( DINA)model,four kinds of attribute hierarchies and the expected dis-crimination method( ED). Date showed that the new three variable-length termination rules have their own advanta-ges.
