双语例句
- The titration points must be selected exactly as the equivalence points of mixed acid ( HA ⅰ+ HA ⅱ) or polyprotonic acid are determined by linear titrimetry, which is one of the important steps to raise the accuracy of linear titrimetry.
线性滴定法测定混合酸（HAⅠ+HAⅡ）或多元酸的等当点时，必须正确地选择滴定点，这是提高线性滴定法准确度的重要措施之一。
