摘　　要：为了给出δ型序列的一种判别法 ,利用δ函数和广义函数序列极限的定义 ,证明了关于函数序列收敛于 δ函数的充分条件和必要条件的 3个定理 .To give a criterion on a sequence of δ type functions, the definitions of the δ function and limit of a sequence of generalized functions were used. The three theorems on the sufficient condition and necessary condition for a sequance of functions to converge to the δ function were proved.
