In this dissertation, refining grains, depositing conductibility carbon film on the surface of the particles and doping mg ~ ( 2 + ) into the lattice of lifepo4 were adopted to improve the electro - chemical performance of the cathode material. the cathode material lifepo4 mainly has two flaws, the low conductibility and the slow li + ion diffusion, which have a bad influence on the performance of the cathode material
論文主要針對制約正極材料lifepo _ 4性能的兩大致命的缺點,即低的電子導電率和低的鋰離子擴散速率,採取材料顆粒的細化、顆粒表面沉積碳導電層以及mg ~ ( ~ ( 2 + ) )離子摻雜等措施對其進行改性探索,以提高正極材料lifepo _ 4的電化學性能。Although arc spraying has the advantages of high deposition efficiency and low cost, only electrically conductive wire materials can be adopted for arc spraying. the quality of coatings produced with plasma spraying and hvof is high, but large volume of plasma spraying equipment makes it difficult to be used on site, and the high investment of equipment, the large consumption in fuel and high cost prevent from spreading of hvof
雖然電弧噴塗的效率高、成本低,但它僅適用於具有導電性的線材噴塗:等離子噴塗及超音速噴塗制備的塗層質量高,但等離子噴塗設備龐大,不適用於鍋爐現場噴塗;超音速火焰噴塗設備昂貴、耗氣量大、塗層成本高,從而限制了它的推廣。For the pemfc cathode, besides above the parameters, the effects of the thickness of the reaction layer, the ion conductivity of nafion electrolyte and the electronic conductivity in carbon phase of the reaction layer on the electrode performance have also been investigated
在對pemfc陰極的研究中,除了以上參數以外還考慮了反應層厚度, nafion ~ ( ? )電解質的離子傳導率以及反應層中碳相傳導率對電極性能的影響。3. the distance of metal wire and ground is smaller, the effective permeability leff, quality factor q and resonance frequency srf is also smaller ; the coil turns increases leff will increase, the q value and resonance frequency srf will drop ; the line width increases leff will drop, resonance frequency srf will increase and the q value is nearly invariable ; the via size, the pad layer size and thickness is little effect the effective permeability leff and resonance frequency srf but seriously influence q value
3金屬導線離地的距離越小,有效電感值leff 、品質因子q 、自諧振頻率srf也越小;線圈圈數增加, leff增加, q值和自諧振頻率srf下降;線寬增加, leff下降自諧振頻率增大q值幾乎不變;通孔大小、覆蓋層的大小及厚度對有效電感值leff和自諧振頻率srf沒有多大影響,但對q值影響較大。This paper describes a reconstructive algorithm which is based on network theory for electrical capacitance tomography technic. there are twelve electrodes in the system. the permittivity distribution of flow with two components within a pipeline is reconstructed. assume the permittivity distribution of the region to be reconstructed. then whole measured area is discretized into a network composed of capacitance. the measurement circuit which contains a pair of source electrode and detecting electrode is taken as a four - terminal network. the across admittance of the four - teminal network is proportional to the capacitance between the source electrode and the detecting electrode. modify the distribution of the permittivity according to the difference between the calculated capacitance and measured capacitance. the experimental results show that this algorithm is effective and can coverge
本文描述了一種用於兩種成份的流體成像的12電極電容層析成像新方法.該方法基於電路的網路理論,首先對重建區域假定一個介電率分佈,用電容網路作為離散化模型,將每一個源電極和探測電極對組成的測量電路看作一個四端網路,該四端網路的跨導與源電極和探測電極之間的電容值是線性關系,這個電容值和測量得到的電容值之間存在誤差,根據這個誤差對修正介電率分佈.通過對不同介質分佈作的模擬實驗結果,證實了該演算法是有效的,收斂的A new method of mix - oxide doped electrochromics is described in this paper. the electrochromic layer and the ionized conductance layer are doped with oxide and metal respectively, which highly improve the characters of response and chromic transitivity of the electrochromic apparatus. finally, the experimental results are presented
