摘　　要：氧传感器具有低成本、结构简单、高灵敏度等优点,在工业、农业、医学和环境等领域具有广泛的应用。用于测量气体中氧分压和水中溶解氧浓度的氧传感器的基本原理相同,只是结构和所用材料有所区别。电化学氧传感器在其实际应用中存在着气候影响、残余电流以及寿命与可靠性等问题,针对这些具体问题,人们也在实际运用中采取了不同的方法加以解决。Oxygen sensors, which have a lot of advantages including low cost, simple structure and high sensitivity, are now applied in many fields such as industry, agriculture, medicine and environment. Oxygen sensors measuring partial pressure of oxygen in atmosphere and those measuring dissolved oxygen in water are based on the same principle, and their differences only lie in the structure and material. The influences of climate, residual current, life and reliability are the major problems existing in the practical uses of oxygen sensors, and here we have different solutions for each of them.
