| 摘 要： | 根据NY525-2002用分光光度法测定有机肥中全磷含量,通过对测试过程中随机效应与系统效应的分析,计算出两种效应对测试过程中所导致的不确定度,并评估了合成标准不确定度和扩展不确定度。该不确定度评价方法在分光光度法测定分析工作中有较强实用价值。

| Abstract: | The phosphorus content in organic fertilizers was determined by spectrophotometry based on the NY525-2002 Standard, and the fixed and random effects were analyzed during the determination to calculate the uncertainty resulting from these effects in the determination process. The combined standard uncertainty and the expanded uncertainty of the total phosphorus content were evaluated. This uncertainty evaluation method is valuable and practical in determination and analysis of total phosphorus content in org... |
