We make comments on [#!me!#], and provide partial wave analysis to the decays of excited heavy S-wave 1- quarkonia into the basic 1- quarkonia state plus . It is revealed that there exist contributions of D-wave transition in , and by using the data-fitting results in [#!me!#]. A possible experimental method to measure the D-wave directly is discussed.
