hydroxy group

When discussed the transesterification reaction, the formula used to calculate ester interchange rate based on the oil's relative molecular weight and the increase of hydroxy group was derived;

在讨论油脂的酯交换改性反应时，推导出了可根据油脂的平均相对分子质量和酯交换后羟值的增加量计算酯交换率的近似公式；

Previous studies indicated it is a basal surface with plenty of hydroxy group and owns quite good biological activity. The interaction of hydrogen bonds, between hydroxy group and polyelectrolyte with lots of amino group, provides the feasibility of the following self-assembly.

研究表明这是一个富含羟基且具有良好生物活性的基底面，由于羟基与富含氨基的聚电解质生物大分子之间的氢键作用，为我们后续的组装提供了可能。

The coke consisted mainly of aromatic compounds with alkyl and polycyclic aromatic hydrocarbons, and it also comprised some aromatic compounds with hydroxy group produced by further oxidation, dehydrogenation and polymerization of phenol on Lewis acid sites.

积炭物种主要为带有烷基的芳烃和多环芳烃，同时含有少量带有羟基的多环芳烃，这可能是由在L酸中心上生成的苯酚进一步氧化、脱氢和聚合形成的。
