two-layer electrode
解釋
雙層電極-
The paper recommends that the placement of voltage - electrode is 0. 509s when the distance from the border of grounding grids to current - electrode is s that is the long border length of grids. ( 3 ) the paper use two - layer theory to describe non - uniform soil. with the different two - layer soil model, some conclusions and formula that have great reference value are presented numerically
綜合各種因素考慮，推薦在距離地網邊緣距離為地網長邊長度s的位置布置電流極，並在0 . 509s布置電壓測量極，在滿足工程精度要求的同時也極大的提高了測量效率。 -
Air electrode, in which nh _ 4hco _ 3 is as pore former, is mainly studied in this paper. the manufacturing process of air electrode, the composition of waterproof and gas diffusion layer, the composition of catalysis layer, and two kinds of catalyst were studied by numbers
本文針對以碳酸氫銨為造孔劑的空氣電極進行研究，分別對電極製作工藝、防水透氣層組成、催化層組成以及兩類催化劑進行了初步系統的探索和研究。 -
In the experiments, two series of catalysts were synthesized by co - deposition and sol - gel methods each. the composition of both waterproof and gas diffusion layer and catalysis layer were optimized by the orthogonal test. meanwhile, quasi - steady cathode polarization curves, x - ray diffraction ( xrd ), scanning electronic microscope ( sem ) were used to analyst the relationship between the microstructure and the performance of air electrode
實驗採用共沉澱法和溶膠凝膠法合成了兩類催化劑;對防水透氣層和催化層進行了正交試驗優化;同時，還採用測準穩態極化曲線， x射線衍射（ xrd ） 、掃描電子顯微鏡（ sem ）等分析測試手段，對空氣擴散電極催化材料、空氣擴散電極界面結構與性能的關系等作了較深入的研究。
