钢铁厂炉前化验室每天要分析大批定硫试样及定炉渣氧化钙试样,而它们均是采取容量法,大量的分析数据的计算,给分析工作者带来不小的负担,因此我们就试制了一种简便的图表法,不用通过计算,而能够从所消耗的标准溶液的毫升数直接读出结果的百分数来。大家知道,在容量分析计算上,当称样固定不变时(我们一直习惯这样做),不难通过简化,将计算式化为消耗标准溶液的毫升数V乘一常数C,而直接得到分析结果百分数:
The steel mill’s front-end laboratory analyzes a large number of fixed sulfur samples and calcined calcium oxide samples on a daily basis, all of which are based on the volumetric method and a large amount of analytical data to be calculated, which brings a considerable burden to the analysis workers. Therefore, we A simple charting method has been tried out that allows you to read the percent of the result directly from the milliliter of the standard solution consumed, without going through calculations. We all know that in capacity analysis and calculation, when the sample is fixed (as we have been accustomed to doing), it is not difficult to simplify the calculation formula is consumed by the standard milliliters of the solution V by a constant C, and directly be analyzed Result Percentage:
