查询词典 optically inactive

Polarimetry, the measurement of optical rotation, of a pharmaceutical article may be the only convenient means for distinguishing optically active isomers from each other and thus is an important criterion of identity and purity.

药用物质的旋光测定法，即测定光学旋转的方法，也许是用于区分具有光学活性的异构体的方法中唯一简便的方法。因此，该方法是鉴别和纯度的一个重要标准。
