摘　　要：生化需氧量(BOD)在线自动监测仪,是采用流通式微生物电极法测量水中生化需氧量的仪器。目前我国尚无针对现场连续使用的不可拆卸生化需氧量(BOD)在线自动监测仪的国家技术规范,文中提供了一种用于在线仪器的校准方法及不确定度的计算方法,为食品药品生产、环境监测领域提供检测依据。On-line automatic biochemical oxygen demand(BOD)monitor is to measure the BOD in water by means of current microbioelectrode.At present,there’s no national technical specification for non-removable on-line automatic biochemical oxygen demand monitors for continuous field use in China.This article is to present a calibration method and a calculation method of uncertainty for on-line detecting instrument,which expects to act as the test basis in food and drug production and environmental monitoring fields.
