摘　　要：利用Ｔｉ＿（５０）Ｃｕ＿（５０）金属玻璃的中于和Ｘ射线衍射，得到了全结构函数和全原子密度径向分布函数，深入分析了它的近邻原子结构和短程有序结构，得出的非晶的近邻原子间距大于相应的晶态结构的间距。By the total structure functions,F(k),and reduced radial distribution functions,G(r),ofTi_(50)Cu_(50) derived from neutron and X-ray diffraction,the paper takes a closer look at the neighbourchemical ordering and shortrange ordering structure of Metallic glass Ti_(50)Cu_(50).Larger interatomicdistances between neighbour atoms are obtained for the glass State than tbose in the corresponding crystalline.
