四面体间隙 meaning in English
tetrahedral interstice
Examples
- In the theoretical simulation on the behavior of single helium atom in aluminum , the varieties of energy data including the formation , migration , binding , and dissociation energies for single helium atom at the interstitial , vacancy , grain boundary , and dislocation sites in aluminum lattice were calculated , based on the density functional theories , general gradient approximation and pseudopotential plane wave method . results showed that the most fittable sites for containing helium atoms inside the cell are vacancies . but in the view of the whole lattice , grain boundaries are the best
计算结果表明,晶内he原子择优占位区是空位,而在整个晶体范围,最有利于容纳he原子的区域是晶界,位错容纳he原子的能力次于晶界和空位;在fcc -铝的间隙位中, he原子优先充填四面体间隙位;晶内间隙he原子是可动的,通过间隙he原子的运动,可在晶内聚集,或被空位、晶界、位错等缺陷束缚。
