We mainly studied the strong convergence of weighted sums of the form 1bn ∑ai (Xi-i=1nE(Xi|Fi-1 ))(or 1bn ∑i= 1 ai Xi) ,where{Xn ,Fn ,n≥1} was an arbitrary Banach space valued integrable adapter sequence (or Banach space valued martingale difference ) and {an ,n≥1} and {bn ,n≥1} were two sequences of positive constants . Some new strong convergence for such weighted sums were proved under mild conditions .
