This parer proved that for the ring R with n left(right) zero pisors, if |R|=n 22 ,then n=2 s+1 (n∈N),|R|=2 2s+1 and the character of R could only be 2,4 or 8;and if R is the commutative ring whose character is 2, then R could only be the 8 element ring with 4 zero pisors.
证明了具有ｎ（＞２）个左（右）零因子的环Ｒ，当｜Ｒ｜＝ｎ２２时，必有ｎ＝２ｓ＋１（ｓ∈Ｎ），｜Ｒ｜＝２２ｓ＋１，且Ｒ的特征是２，４或８。
