测量葡萄糖溶液旋光度时，零点校正是指： When measuring the optical rotation of glucose solution, zero correction refers to
A.旋光计测量室放入蒸馏水试管，找出弱照度的均匀视场（零度视场），记下此时刻度盘的左右读数平均值，即零点校正值 Put tube contained distilled water into the polarimeter measuring chamber, find out the uniform field of view (zero degree field of view) with weak illumination, and record the average reading values from the left and right dial at this time, that is, the zero correction value
B.旋光计测量室不放任何试管，找出弱照度的均匀暗视场，记下此时刻度盘的左右读数平均值，即零点校正值。 Without any test tube in the polarimeter measuring chambe

为了消除溶剂对样品旋光度的干扰，在测定样品前需要用溶剂来校正旋光仪的零点。
