介绍了一种新型测氧微传感器的特点与应用。该测氧微传感器除了有一个测量阴极外,还带有一个内保护阴极,其测量零电流很低,信号极稳定且易于制作。该测氧微传感器由于尺寸小、稳定性高,不仅可方便的应用于常规环境测量中,而且还可使用于过去因范围太小而无法进行测量的不少研究领域中。 The characteristics and application of a new oxygen micro-sensor are introduced. In addition to measuring the cathode, the oxygen sensor has an internal cathodic protection, which measures very low zero current and provides a very stable and easy-to-make signal. Because of its small size and high stability, the micro-oxygen sensor can not only be conveniently used in conventional environmental measurement, but also used in many fields of research in the past because the measurement range is too small to be measured.
