英语翻译
An alkalin solution of copper salt was subjected to hot reduction by direct titration of a protein-free solution,in the presence of methylene blue,without inversion.Total sugar was determined after inversion with concentrated hydrochloric acid.
英语翻译An alkalin solution of copper salt was subjected to hot reduction by direct titration of a protein-free solution,in the presence of methylene blue,without inversion.Total sugar was determined after inversion with concentrated hydrochloric
大致含义是：在亚甲基蓝存在并且不发生转换的条件下,铜盐的碱性溶液在无蛋白质溶液的直接滴定作用下很容易被热还原.总糖量在用浓盐酸转换后即可确定.
同盐碱溶液通过无蛋白质溶液的直接滴定后，易受热还原。在亚甲基蓝存在下，没有转化。总糖测定后和用浓盐酸转化。
化学问题？太专业了！翻得不好请见谅
一种黄色【copper】的碱性盐溶液可通过一种无蛋白溶液的直接滴定法进行热还原，在呈亚甲蓝色时，不发生转化，用浓盐酸转化后，变成纯糖。
铜盐的碱性溶液在亚甲基蓝存在条件下，被无蛋白质溶液直接滴定后会急剧减少，没有化学反应。所有糖类在和浓缩的氢氰酸反应后确定下来。
