摘　　要：基于气体溶解定律,提出了校准微量溶氧仪的解吸方法,设计制造了解吸法溶解氧分析仪检定装置,通过理论计算确定了检定装置的技术指标及溶氧水的测量不确定度,并通过实验验证了该方法的可行性。The desorption principle of calibrating low-level dissolved oxygen analyzer and a set of verification apparatus were established based on gas-dissolved law. The technical parameters of apparatus and uncertainty of concentration of dissolved oxygen water were determined through calculation. The method was verified to be feasible for calibrating dissolved oxygen analyzer by a series of tests.
