[求助] 帮忙翻译一下!谢谢!

从材料中提纯分离化合物,以便提高材料的利用效率。以不同浓度的叉叉和叉叉溶液对材料蒸煮,研究在不同浓度下对化合物含量的影响,并通过扫描电镜观察材料预处理后表观形貌的变化情况,叉叉处理后的材料进行高效液相色谱的检测分析材料的水解情况,以5%的叉叉溶液预处理的材料可使化合物含量提高到58.33%,收到了较好的预处理效果。而采用叉叉预处理的稻杆时,浓度超过1%就会使材料中的化合物发生水解造成材料损失。采用质量分数为5%的叉叉溶液预处理材料可以有效的提纯化合物,为下一步利用材料中的化合物打下了基础。

楼上的!大意好像是:同时添加一种或者两种晶体,然后同时添加硫代硫酸钠直到红色消失或者变紫。

       Material from the purification of compounds isolated in order to improve the efficiency of the use of the material. In different concentrations and Cha Cha Cha Cha solution to the cooking materials, research in different concentrations of the compound content and materials by scanning electron microscope after pre-apparent changes in morphology, Cha Cha treated materials Detection of high-performance liquid chromatography analysis of the hydrolysis of the material to 5% of the Cha Cha solution will enable Preconditioning of the material content of compounds to 58.33 percent, has received good pre-effect. The use of rice under the pre-Cha Cha, the concentration of more than 1% of materials would occur in the compound material losses caused by hydrolysis. Using 5% of the Cha Cha materials solution preprocessing purified compounds can be effective, the next step for the use of the materials in the compound to lay a foundation.
