中文摘要：

利用May谱序列证明了,当n〉3时,乘积元素l_ng_0∈Ext_A5,pn＋1q＋2 pnq＋pq＋2q（Z_p,Z_p）和h_0g_n∈Ext_A（3,pn＋1q＋2 pnq＋q）（Z_p,Z_p）是非平凡的,并且l_ng_0和h_0g_n在Adams谱序列中不是d_r（r≥2）边缘,其中：p≥5,q=2（p-1）.

英文摘要：

By using the May spectral sequence,it is proved that the two products l_ng_0∈Ext_A5,pn＋1q＋2 pnq＋pq＋2q（Z_p,Z_p） and h_0g_n∈Ext_A（3,pn＋1q＋2 pnq＋q）（Z_p,Z_p） are nontrivial,and both of them are not the dr-boundary in the Adams spectral sequence,where n 3,p≥5,q = 2（p- 1）.
