非晶态合金结构的实验测定和理论模型研究目前已取得的某些结果,可以作为提出菱面体晶胞模型的实验基础.以非晶态NiP合金为例,g(r)曲线各峰的位置r/σ=1.00,1.66,1.91,2.53,3.36,4.17,4.53,(σ为原子直径);第1峰曲线下面积可给出最近邻原子的配位数,n≈12;当r≥r_s时,g(r)=1,一般r_s=15±+?,表明非晶态结构短程有序区的大小. Some experimental results of amorphous alloy structure experiment and theoretical model can be used as the experimental basis for the proposed lattice cell model of rhombohedral. Taking amorphous NiP alloy as an example, the position of each peak of g (r) curve (σ is the atomic diameter); the area under the curve of the first peak can give the coordination number of the nearest neighbor atom, n ≈ 12; when r ≧ r_s , G (r) = 1, usually r_s = 15 ± +?, Indicating the size of the amorphous structure short-range orderly region.
