【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。
