摘要
通过研究交换Ｂａｎａｃｈ代数Ａ与Ａ／ｒａｄＡ的关系，得到了Ａ具有谱延拓性质、强谱延拓性质、乘法Ｈａｈｎ＿Ｂａｎａｃｈ性质的充要条件．作为一个推论，当Ａ为半单时，得到Ｍｅｙｅｒ（１９９１）的结论．
In this paper, investigates the relationship of commutative Banach algebras A and A /rad A , We get the sufficient and necessary conditions of A having spectral extension property. Strong spectral extension property, multiplicativa Hahn_Banach property. As a corollary, When A is a semi_Simple Algebra, we have the results of Meyer(1991).
