摘　　要：根据区间数和泛灰数的定义及其运算，以及它们之间的相互转化，举例说明了泛灰数在区间分析中的局限性，论证了泛灰数和区间数在运用中所具有的优缺点，从而澄清了某些结论中的模糊之处，并得出一些一般结论．Based on the definitions and operations of interval number and generalized gray number, and their mutual transformation, this paper illustrates the limitation of general gray algebra in interval analysis. The advantage and disadvantage of interval number and generalized gray number in their applications to interval analysis are discussed. The vaguess in some document are clarified. And, some general conclusions are drawn.
