摘　　要：We reported the observation of Y（2175） in Фfo（980） mass spectrum in J/ψ → ηФfo（980） with fo（980） →π＋π^- and the observation of a broad 1^-- resonance of K^＋K^- mass in J/ψ→ K^＋K^-π^0. The results from the partial wave analyses of J/ψ→γπ^＋π^- and γπ^0π^0, as well as J/ψ →pK^-∧. are also presented.We reported the observation of Y（2175） in Фfo（980） mass spectrum in J/ψ → ηФfo（980） with fo（980） →π＋π^- and the observation of a broad 1^-- resonance of K^＋K^- mass in J/ψ→ K^＋K^-π^0.
