Abstract
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 $\pi\pi$. It is revealed that there exist contributions of D-wave transition in $\psi'\longrightarrow J/\psi\pi\pi$, $\Upsilon(2S)\longrightarrow \Upsilon(1S) \pi \pi$ and $\Upsilon(3S)\longrightarrow \Upsilon(1S) \pi \pi$ by using the data-fitting results in [#!me!#]. A possible experimental method to measure the D-wave directly is discussed.
