求翻译：3) 结果计算 由待测样品与碱处理样品的吸光值之差查找标准曲线，即可以计算出样品中抗坏血酸的含量，也可以直接用碱处理液位参比，测得待测液的吸光值，然后对比标准曲线，计算出样品的抗坏血酸含量。是什么意思？

3) The results calculated by the base-treated sample and the sample absorbance values ​​to find the difference between the standard curve, which can calculate the ascorbic acid content of the sample can also be directly treated with alkali level reference, the measured absorbance of test solution ,

3) * * calculate results to be measured by alkali treatment samples with samples of the difference between drug-find standard curve, that is, it can be calculated in a sample of ascorbic acid content, and it can be used directly from liquid alkali treatment than that measured the liquid to be measur

3) The result computation by treats measured the sample and the alkali treatment sample difference of search standard curve extinction value, namely may calculate in the sample the antiscorbutic acid content, also may with the alkali treatment fluid position senate ratio, obtain directly treats meas

3) result calculated by the test sample with alkali treatment they absorb the difference between the values of the samples to find standard curve, that is, content of Ascorbic acid can be calculated, or directly by alkali treatment level reference, the measured test liquid absorbency, and compared t

3) The results calculated by the base-treated sample and the sample absorbance values ​​to find the difference between the standard curve, which can calculate the ascorbic acid content of the sample can also be directly treated with alkali level reference, the measured absorbance of test solution ,
