摘　　要：本文对基于麦氏比浊原理的细菌浊度分析仪进行了简要概述,探讨了该类仪器零点漂移、示值稳定性、重复性、示值误差的测量方法以及示值误差测量值的不确定度评定,并进行了实验验证,为该类仪器的校准和测试提供了合理方法,保证了仪器量值的准确性。This thesis gives a brief overview of the bacteria turbidity analyzer based on the principle of Mc Farland turbidity. The measurement methods of zero drift,indication stability,repeatability,indication error of this kind of instruments are discussed. The uncertainty of indication error of measurement results is assessed and verified by experiments,which provides a reasonable method for the calibration and testing of the instruments,and ensures the accuracy of the instruments.
