为了建立费休氏法测定头孢拉定胶囊水分的不确定度评定,根据《测量不确定度评定与表示》(JJF1059-1999),分析不确定度的来源,通过建立数学模型,对水分测定过程中各影响因素进行分析评估,计算各变量的不确定度,合成不确定度,得出水分测定的扩展不确定度为0.28%(k=2),该方法适用于费休氏法测定头孢拉定胶囊水分的不确定度评定。
In order to establish the uncertainty assessment of cephradine capsule by Fisher’s method, according to “Evaluation and Expression of Uncertainty in Measurement” (JJF1059-1999), the source of uncertainty was analyzed. By establishing mathematical model, And the influencing factors were analyzed and evaluated. The uncertainty of each variable was calculated and the uncertainty of synthesis was calculated. The extended uncertainty of the determination of moisture was 0.28% (k = 2). This method was suitable for the determination of the water content of cephradine capsules Uncertainty assessment.

大棚蔬菜的水分管理,既要看天,又要看地,还要看时间,不能简单地遇旱浇水,要做到以下几点:1.浇水量不宜过大。在严寒季节,棚内气温和地温都比较低时,浇水量要小,间隔时间要长,
