系统误差:(Systematic Error)一种非随机性误差。
称偏倚。是由于仪器准确度或灵敏度不一致,调查人员或检验人员的操作不统一,掌握标准偏高或偏低等系统错误,使研究的结果偏离总体的真值而造成的误差。在实验设计时坚持随机、对照、重复的原则,实验仪器经过认真的校正,调查人员进行严格培训并统一标准,实验人员熟练掌握操作方法等,都可以有效减少系统误差。
Weigh bias. Because instrument accuracy or sensitivity are abhorrent,be, the operation of the member that investigate personnel or identifier is skimble-scamble, master the systematic error such as standard on the high side or on the low side, the true value that makes the result deviate of research overall and the error that cause. Hold to when the experiment is designed random, contrast, reduplicative principle, experimental instrument course is serious corrective, investigation personnel undertakes grooming strictly and unite a standard, experimental personnel adroitness masters operation method to wait, can reduce systematic error effectively.
