single phase reaction的意思|示意

The results show that the content of tetragonal phase is increasing in BNBT ceramics by direct reaction sintering method but still exhibiting a single phase of perovskite structure.

结果表明，直接反应烧结法不影响BNBT陶瓷的钙钛矿相结构，但可使准同型相界处组成的四方相含量增加；

Based on the mathematical model of the single pore electrode, the effective three-phase boundary length of the electrochemical reaction is defined and calculated.

在单孔电极模型基础上定义了电化学反应的有效三相分界线长度概念，并给出了对应的计算方法；
