The present paper deals with the Donaldson invariants of 4-manifolds with embedded tori. For 4-manifolds with embedded 2-torus whose intersection is+ 1, a gluing formula of the Donaldson invariant on the 2-homology represented by 2-torus was obtained. 讨论了具有嵌入环面4-流形的Donaldson不变量,得到了具有自交数为+1的嵌入环面的4-流形的Donaldson不变量在环面表示同调类上的一个粘合公式。
