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.

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。
