In attempt to directly compare the sound response characters of the same bf neurons or different bf neurons and their interactive relation, the double recording microelectrodes were penetrated into two different neurons in iso - frequnency laminas or hetero - frequency laminas. taking advantage of frequency tonotopical arrangement in 1c of bats, it was explored how the neurons integrated different parallel processes of the same sound information. in the case of which, we hoped to explore the relation between the sound response characters of the central auditory neurons and neural modulation in background noise for the further understanding of the mechanism in the central auditory neurons extracting sound signals
本研究以大棕蝠( bigbrownbat , eptesicusfuscus )為模型,利用ic聲調組構排列成同頻層這一結構特點,突破單電極記錄和檢測神經元的方法,同時推進兩單電極至一個同頻層或兩個同頻層的兩個不同神經元,試圖從細胞水平直接比較兩個具有相同和不同最佳頻率的神經元聲信號的加工處理特徵、以及它們之間的相互關系,以期窺探它們在對同一聲信號處理過程中的整合奧秘,並以此為基礎分析和探討背景噪聲條件下中樞神經元聲反應特徵與神經調制的關系,以期進一步了解中樞聽神經元聲信號提取的機制。Oxygen diffusion transport and electrochemical reaction in the oxygen cathode of direct methanol fuel cell ( dmfc ) have been expressed with the tffa model. model calculation has been carried out to investigate the effects of structural parameters of the dmfc cathode on the electrode performance, which is respectively represented by the curve of cathode overpotential versus current density. much attention has been paid to parameters including the porosity of the reaction layer, the thickness of the thin - film on the flooded - agglomerate, the radius of the flooded - agglomerate, the volume fraction of the flooded - agglomerates in the reaction layer
本文首先運用tffa模型描述直接甲醇燃料電池( dmfc )陰極氧氣的傳遞和電化學反應過程,研究了過電位-電流密度曲線受陰極結構參數變化的影響程度,其中著重考慮了以下幾個參數:催化層的孔隙率,浸漬聚集體薄膜的厚度,浸漬聚集體的半徑,浸漬聚集體在催化層中的體積分數。The calculation results show that the radius of the gas channels in the reaction layer and the porosity and average pore radius of the gas - diffusion layer seem to be less important for the performance of the electrode
模型結果表明對于電極性能而言,氣體擴散層的孔隙率與平均孔徑以及反應層氣體通道的半徑,相對其他參數來說顯得不太重要。Oxygen diffusion transport and electrochemical reaction in the oxygen cathode of alkaline fuel cell ( afc ) and pemfc have been expressed with the tffa model, including oxygen transferring in gas channel of gas diffusion layer and reaction layer, oxygen dissolution and diffusion in thin - film of reaction layer, oxygen reaction and diffusion in flooded - agglomerate of reaction layer and the conduction of electron and ion. numeric algorithm of the model equations is also obtained
本文將tffa模型應用於堿性燃料電池( afc )和質子交換膜燃料電池( pemfc )陰極,推導出陰極各種傳遞和反應過程的描述方程,包括氧氣在氣體擴散層和反應層氣體通道中的擴散,氧氣在反應層薄膜中的溶解和擴散,氧在反應層浸漬聚集體中的反應和擴散以及電子和離子的傳導,並給出方程的數值解法。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
薄膜浸漬聚集體( tffa )模型假定由氣體擴散層和反應層構成的氧氣擴散電極在反應層中是一種二次構造形式的多孔結構。Special attention is paid to the consequences of methanol crossover in cathode reaction and cathode over - potential. good agreement is found between simulations and experiments in regard to the v - i character of dmfcs. based on the theory of parallel electrode reaction, it becomes possible to obtain quantitatively the value of over - potential caused by methanol crossover, which is either implicit or not included in the overall cathode over - potential in previous models
該模型涵蓋了dmfc中的主要物理化學過程,包括:甲醇水溶液在膜電極內的擴散、對流和電遷移;質子在陽極催化劑層和陰極催化劑層內的傳遞;氧氣、水蒸汽在陰極的擴散;陽極催化劑層內的甲醇氧化反應動力學;以及陰極催化劑層內的氧還原和甲醇氧化反應動力學。The main work in this thesis includes two contents as follow : 1 we have investigated the properties of ohmic contact between metal electrode ( al and ti / al electrode ) and n - gan dealed under different annealing conditions. by using xrd sims analytic methods and i - v measuremnet, we analysed the interface between metals and gan, and suggested that it is effect to decrease the value of the ohmic contact
