And just as the proponents of " modern art " cast their slings and arrows at the oh - so 19th century style , varying political groups brought out their personal arsenals of vitriolic prejudice in damning one aspect or other of mucha ' s work 如同现代艺术的支持者对十九世纪的艺术风格大肆鞑伐,不断改变的当政团体也带著他们个人的积怨与激烈偏见来曲解、抨击慕夏的作品。
To determine the vitriolic solute quality mark in sewage does following tests : take 10 grams this sewage , chase to the middle of sewage drop join solute quality mark to change sodium solution for the oxyhydrogen of 4 % , if plan institute is shown , the ph change of the quality of solution of natrium of oxidation of place drop hydrogenation and solution concerns 为测定污水中硫酸的溶质质量分数做如下实验:取10克该污水,向污水中逐滴加入溶质质量分数为4 %的氢氧化钠溶液,所滴加氢氧化钠溶液的质量与溶液的ph变化关系如图所示。
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。
