| 摘 要： | Co81P19及Ni64B36非晶态合金的无规硬球密堆的初始位形,分别用Lenard-Jones势及Morse势进行了松弛。在Ni64B36的计算中,考虑了两种位移分数f=0.005及f=1情况。由计算数据可求得体系总能量,简约偏径向分布函数及角分布函数。文中讨论了势函数的局域性及关联性对二元非晶态合金中的化学短程序所造成的影响。

| Abstract: | The primary DRPHS configuration are relaxed with Lenard-Jones and Morse potential respectively for Co81P19 and Ni64B36 amorphous alloys. Two displacement fraction f=0.005 and f=1 are considered in the case of Ni64B36. Total energy, reduced partial distribution function and angular distribution function are obtained from the calculated data. Effect of localization and correlation of potential function on chemical short range order in binary amorphous alloys are discussed. |
