Both the samples are all a mixed conductor of oxide-ion and electron hole with an almost same oxide-ionic transport number under oxygen atmosphere.
这两个样品在氧气氛中均是氧离子与电子空穴的混合导体，具有几乎相同的氧离子迁移数。

In the conductor or some solutions, the true migration is the belt electric charge granule, like free electron, ion.
在导体或一些溶液中，真正移动的是带电荷的粒子，如自由电子、离子。
