【系统误差】(systematicerror)

亦称“恒定误差”。在同一条件下多次测量同一量时,误差的数值和符号保持不变,或在条件改变时,按某一确定的规律变化的误差。产生的主要原因:(1)分析方法不完善。如在重量分析中,由于沉淀的溶解和共沉淀现象等;在职滴定分析中,由于反应进行不完全和*等当点与滴定终点不符合等,均将系统地影响测定结果偏高或偏低。(2)仪器本身不够精确。如砝码重量、容量器皿刻度等。(3)试剂不纯。(4)操作者主观上带来的误差。如对滴定终点颜色的辨别不同等。为保证分析结果的准确度,对这类误差必须尽量减小以致消除。常采用标准试样和标准方法来进行校正,或由不同单位、不同人员测得的结果,进行对照和评价,从而得出校正系数以消除之。
