The product has chief three kinds of models : hx - 30 , hx - 50 and hx - 100 , the number means showing oxygenous absorption , but the actual oxygenous absorption is over six times than showing quantity 本产品除氧剂主要有hx - 30 hx - 50 hx - 100三种型号，其中的数字为标示的吸氧量，而实际吸氧量一般为标示量的6倍以上。

Because thermal insulation was in oxygen - riched condition of afterburner and charred layer was porous , oxygenous gas in mixture would penetrate into charred layer and chemical reaction would take place in whole charred layer , which intensified the ablation process 由于绝热层处于二次燃烧室富氧的环境中，而且炭化层为疏松多孔状物质，因此将化学反应引入到整个炭化层中。

In order to improve the electro - catalytic activity of platinum based catalyst to methanol oxidation , in this thesis , firstly prepare heteropoly acid modified pt / gc electrode with different concentration by cyclic voltammetry method , and then test the cyclic voltammetry curves individually in vitriolic and methanol solution . the study shows the best concentration for both phosphomolybdic acid and phosphotungstic acid is 1 10 ~ ( - 3 ) mol / l . and find the more heteropoly acid modified on electrode , the lower peak - up potential towards methanol because of the existence of oxygenous species 为了改善铂基催化剂氧化甲醇的催化活性,本论文首先通过循环伏安扫描法制备了不同浓度磷钼酸和磷钨酸修饰的pt / gc电极,通过研究pt / gc电极在修饰前后在硫酸溶液中及含甲醇的硫酸溶液中的循环伏安行为发现,磷钼酸和磷钨酸均能在ptru / c电极上发生氧化还原反应,而且杂多酸修饰浓度对pt / gc电极氧化甲醇的催化活性有很大影响。

It was concluded that , the structure of ito thin films were influenced by many working parameters such as substrate temperature , oxygenous pressure and substrate and so on . it was indicated by sem spectra of zno thin films that the surface of the sample was leveled off , and the crystals were felsitic 结果表明，对于ito薄膜，薄膜的光电性能薄膜结构的择优取向性和与衬底温度、溅射氧气压等工艺参数有很大关系， ito薄膜的sem表明，样品表面较平整，且晶粒也比较致密。
