提出了门模型，使得只有当非移动的（门）离子概率性地离开以保持足够的空间时，移动的离子才在相邻的位置之间跳跃：通过考虑硬球离子围绕其稳定位置的振动，根据Vineyard方法计算跃迁概率率Γ。所得到的Γ是激活型的，激活能随着由移动的和不移动的离子半径定义的重叠长度的增加而增加，也随着门频率的增加而增加。
The gate model is proposed such that a mobile ion happens to hop between adjacent sites only when immobile (gate) ions probabilistically move away to keep an enough space: By taking account of hard-sphere ions vibrating around their stable sites, the transition probability rate Γ is statistical-mechanically evaluated according to the Vineyard method. The obtained Γ is of activation-type where the activation energy increases with the overlap length defined with radii of mobile and immobile ions, and also increases with the gate frequency.
