摘要：

We reported the observation of Y(2175) in phi f(0)(980) mass spectrum in J/psi - eta phi f(0)(980) with fo(980) -> pi(+)pi(-) and the observation of a broad 1(--) resonance of K+K- mass in J/psi -> K+K-pi(0). The results from the partial wave analyses of J/psi -> gamma pi(+)pi(-) and gamma pi(0)pi(0), as well as J/psi -> pK(-) (Lambda) over bar are also presented.
