[求助] 英语高手帮忙翻下这几句话 谢谢!!!

根据黄酮类化合物O-糖苷中苷元的苷化位移规律。
       根据文献[3],当糖上的羟基甙化时将使该-OH所在碳原子产生低场位移,半乳糖的C-6化学位移在成甙前约为62.0ppm,在化合物1的碳谱中,化学位移65.4,66.9,68.0,69.9处有四处碳信号,信号明显处于低场,比半乳糖的C-6化学位移成甙前向低场位移了+4~+6个单位,应该对应的是四个半乳糖的C-6信号,根据以上分析,确定四个半乳糖的C-6位都成了糖甙。

According to the law of displacement for flavonoid O-glycoside daidzein glycosides…         
According to the literature [3], the glycosides for hydroxyl of sugar occur will induce a low-field shift for the carbon atoms connected to –OH groups and the chemical shifts for C-6 of galactose was about 62.0ppm before glycoside. Based on the 12C-NMR of compound 1, it was shown that there were four chemical shifts namely 65.4, 66.9, 68.0 and 69.9 ppm. Such signal mentioned above was obviously in the low-field, which was changed to low-field by +4 to +6 units compared with the C-6 chemical shifts for galactose before glycosides. This might correspond to the signal of a 4.5 galactose C-6. According to the above analysis, it was confirmed that C-6 bits of 4.5 galactose had changed into glycosides.

4.5 galactose  , 应为4 galactose ,galactose 本身是半乳糖的意思,嘿嘿。
