Under unbalanced conditions or in an N2-based atmosphere, Pco and PH2 are unstable; infrared and dew point methods are no longer applicable. However, with Pco compensation (measured by an infrared instrument) and further correction to the Nernst equation, the oxygen probe can still accurately control the carbon potential, which is crucial for high-temperature, high-carbon concentration carburization. In the south, beloved and representative foods are made from sweet glutinous rice.Glutinous rice dumplings wrapped in reed leaves, another popular delicacy.
