What all of these channels have is what's called a selectivity filter, so this filter filters out the type of ion that's going to be allowed through.
这些离子通道都有的一部分，就是所谓的选择性过滤器，这个过滤器，会滤过允许穿过的离子。
In this model, ion conduction involves transitions of three states, with one three-ion state and two two-ion states in the selectivity filter respectively.
在这一模型中，离子通道的选择性过滤器主要处于三个态，一个三离子态和两个两离子态，转导过程用这三个态之间的相互跃迁来描述。
