Abstract
In this paper, we have a further discussion about quadratically hyponormal weighted shifts with weight sequence : a:1;1;pa;.pb;pc;pd.^ on the basis of sufficient conditions for positively quadratically hyponormal weighted shifts. We set examples of quadratically hyponormal weighted shifts with weight sequence of the above form, and also establish a general method for setting examples.
