The thin - film and flooded - agglomerate ( tffa ) model assumes that the oxygen diffusion electrode made of a gas - diffusion layer and a reaction layer possesses a double - scales of porous structure in the reaction layer 薄膜浸渍聚集体( tffa )模型假定由气体扩散层和反应层构成的氧气扩散电极在反应层中是一种二次构造形式的多孔结构。
2.
2 ) an efficient model based on physical similarity was made to simulate the current transformers " nonlinear magnetizing characteristics and to compensate error from outside . a similar magnetizing current extracting method based on bang - bang control was advanced to maximally extract the similar magnetizing current ( 2 )针对电流系统中大量运行的0 . 5级电流互感器，利用物理相似原理在互感器二次构造相似电流互感器，提出基于bang - bang控制的相似激磁电流提取方法，能够最大程度的提取相似激磁电流。
