The scanning electron microscope analyses proves that the bonding mechanism of this process is liquid phase sintering, the change of surface freedom energy is the motivity for sintering. 扫描电镜分析证实,此复合粉末体系的激光烧结是基于液相烧结机制,表面自由能的改变是其烧结的原动力。
According to quantum models of electron probability distributions, a simplified static electric charge model for 4s and 3d electrons of α-Fe atoms is obtained. The bonding force and potential energy between a-Fe atoms at room temperature are calculated. 遵照量子力学定态电子几率分布规律,得出Fe原子4s和3d电子几率分布的简化静电模型,对o&Fe晶格中原子键合力和键能进行计算。
