阴极通常是以下三类材料：一种层氧化物，例如钴酸锂、一种阴离子聚合物，例如磷酸锂铁，或者是一种尖晶石，例如锰酸锂，象例如二硫化钛之类材料曾经是最初使用的材料。

The differences of the micro structure and properities of the bulk sinters, between the fabrication methed of powder metallurgy and reactive synthesis for silver tin oxide composite, are studied in prensent thesis. With the increase of the tin oxide content in silver matix, the electric conductivity of the composite tended to decreace. While in the same tin oxide content, the electric conductivty of the composite fabricated by reactive synthesisis better than that by powder metallurgy. One of the reasons is that the regular net structure existing in former composite.

研究了两种方法即粉末冶金法和反应合成法制备的银氧化锡复合材料烧结坯在组织上的区别和性能上的差异，两种方法制备的银氧化锡复合材料，随着氧化锡含量的升高，材料导电性均呈下降趋势，而相同成分的材料，反应合成法制备的银氧化锡复合材料的烧结坯的导电性要优于粉末冶金法，有规则的网络状组织结构是反应合成法制备的烧结坯导电性好的原因之一。

Positive nerve fibers are in pedal nerve cords and visceral nerve cords. There are no neuronal nitric oxide synthase or inducible nitric oxide synthase positive cells or fibers in the nervous system. A few of endothelial nitric oxide synthase strongly positive nerve cells are identified in pedal ganglia and visceral ganglia. Weakly positive cells and nerve fibers of eNOS can be seen in all of the ganglia and nerve cords.

免疫组化定位表明，神经型一氧化氮合酶和诱导型一氧化氮合酶在整个神经系统内均呈阴性；足神经节和脏神经节内有少量神经细胞呈内皮型一氧化氮合酶强阳性；各神经节和神经索内的部分小细胞和神经纤维呈eNOS弱阳性。

The main work of the article was to synthesize a suitable monomer, bis(4-carboxyphenyl)phenyl phosphine oxide, as the retardant for poly fibre. The procedures were divided into three steps: dichloride phenyl phosphine oxide was synthesized and bis(4-methyl phenyl)phosphate oxide was prepared from DCPP by Friedel-Crafts reaction.

双苯基氧化膦是一种适用于PET纤维阻燃改性的新型有机磷阻燃剂，本文主要研究了其合成工艺，整个合成路线分为三步，通过Friedel-Crafts烷基化反应制备了苯基二氯化膦，进而通过Friedel-Crafts酰基化反应合成了双苯基氧化瞵，经氧气、高锰酸钾氧化得到了产品BCPPO。
