1) exchange splitting
交换分裂
2) meiotic crossing over
减数分裂交换
3) mitotic crossover
有丝分裂交换
4) exchange splitting
交换劈裂
1.
The results show that(1) the exchange splittings of the d-band and the magnetic moments of the Fe-atoms are different in the two clusters;(2)the change distribution in both clusters is not uniform,showing that the electrons are transferred from peripheral atoms to inner atoms,and the spin-direction(up or down)of the electrons transferred is in accordance with the symmetric characteristics.
用MS-Xα方法研究了Fe8原子簇(具有D6h对称)和Fe15原子簇(具有Oh对称)的电子结构,结果表明:(1)两种原子簇中的Fe原子磁矩及其d能带中的交换劈裂性质互不相同;(2)两类原子簇中的电荷分布不是均匀的,电荷倾向于从外围原子向内部原子上转移,并且被转移电子的自旋方向(正自旋或负自旋)与原子簇的对称性质密切相关。
5) ferromagnetic exchange splitting
磁交换劈裂
6) salt exchange
盐分交换
1.
