摘　　要：基于可信性测度,定义了二维离散型模糊向量和二维连续型模糊向量的联合熵,并研究了它们的极小性、极大性、单调性,以及二维简单模糊向量的扩展性和严格凹性。Based on the notion of credibility measure,a definition of joint entropy for 2-dimensional fuzzy vectors is formulated. The minimality,maximality and monotonicity of the joint entropy,as well as the expansibility and strict concavity of the joint entropy for 2-dimensional simple fuzzy vectors,are investigated.
