一、前言 目前,测量常温下的氧气分压,多数是系用克拉克形的氧气传感器。这种传感器的工作原理是通过透气膜,使内部电解液和试料的氧气分压平衡,在插在内部电解液中的铂和金的阴极和阳极之间施加一定的电压,随后测量此时通过氧气的还原

First, the preface At present, the measurement of oxygen partial pressure at room temperature, the majority is the Department of Clark-shaped oxygen sensor. The working principle of this sensor is through the gas permeable membrane, the internal electrolyte and the oxygen partial pressure of the sample balance, inserted in the internal electrolyte between the platinum and gold cathode and anode to impose a certain voltage, and then measure the time Through the reduction of oxygen
