对二苯碳酰二肼分光光度法测地下水中六价铬的不确定度来源进行分析、计算和合成，标准曲线的不确定度采用线性双误差拟合。地下水样品测定结果表明，影响测定结果的不确定度因素主要来源于六价铬标准系列溶液配制和样品的重复测定，对地下水样品中六价铬测定的不确定度作了评估。
對二苯碳酰二肼分光光度法測地下水中六價鉻的不確定度來源進行分析、計算和閤成，標準麯線的不確定度採用線性雙誤差擬閤。地下水樣品測定結果錶明，影響測定結果的不確定度因素主要來源于六價鉻標準繫列溶液配製和樣品的重複測定，對地下水樣品中六價鉻測定的不確定度作瞭評估。

The main causes of uncertainty in determination of sexivalent chromium in groundwater by diphenyl- carbazide spectrophotometric method is analyzed, calculated and synthesized, using the calculating model of standard curve of double error fitting uncertainty in the course of standard curve fitting. The result of determination of sexivalent chromium in groundwater suggests that the main causes of uncertainty that affect the determination results are preparation of sexivalent chromium standard series solution and repeated measurement of the sample. In addition, the uncertainty in the determination of sexivalent chromium in groundwater is evaluated.
