To all who have kindly shared their insight about the
question with me:
It's my great pleasure to find one day after my posting the question
that so much information arrived.   Thanks to J.R.KLein, T.Goodwillie,
M.A.Arkowitz , M.Golasinski and aniceto@agt.cie.uma.es .

Now I think I can prove that , under certain connectivity condition,
maps in the homology decomposition of a co-H-map (not induced map
between homology decompositions)are co-H-maps using information
about connectivity of $fbf$.

Thanks a lot for all who have shared their informations with me.
Thanks also Davis and Wilkerson for maintaining the Hopf archive.

Best wishes
Pan Jianzhong
