The structure of the metallic glass Ni64B36 is simulated by a computer model which consists of two different size spheres. We calculate the partial radial distribution functions, the angular distribution functions and the homogeneity of the model, and discuss the chemical short-range order of the structure. All the results show that in the transiion metal-metalloid glasses, the relative distribution of the metalloid atoms is an important characteristic of the chemical short-range order, this can be characterized by the site rc of the first split peak of the metalloid-metalloid distribution function.
