Since ρ〓,ω are neutral vector mesons, the G-parity breaking is caused by the isospin symmetry breaking. We study the form factor of π, F〓, which is an important observable related to ρ〓-ω mixing problem.

在这个问题中，由于ρ〓，ω都是中性矢量介子，因此G宇称的破坏主要是由同位旋对称性破缺引起，在讨论这个问题时我们首先讨论了对ρ〓-ω问题有重要意义的π介子的电磁形状因子F〓。

Our paper is organized as follows: lIn the quarkonium-quarkonium mixing scheme, we predict the mass of isoscalar of the 3~1S_0 nonet(1900±12MeV).
