摘　　要：采用改变玻璃体系，添加Ｔａ＿２Ｏ＿５，ＴｉＯ＿２，ＷＯ＿３，ＺｒＯ＿２等氧化物调整玻璃性能的方法，提高镧玻璃的化学稳定性。The chemical stability of lanthanum glass is influnenced by the glass systems. Lanthanumglass;ystems of Si-B-La-Ba and B-La-Zn-Ba are clianged into the systems of B-La-Y with additives ofTa_2O_5, TiO_2, WO_3, ZrO_2, etc, added for adjusting the glass properties and improving the chemicalstahility of the giass.
