Once the measurement connections are made, take care to avoid errors due to thermally generated potentials. 连好电路以后，特别注意避免由热电动势引起的误差。
A theoretical formula was applied to this process so that the open circuit voltage could predict the limit of deoxidization reaction. 通过电池电动势与时间关系的数学模型，得出外电路电压与熔池中氧含量的关系，从而根据外电路电压可以预测脱氧反应进行的程度。
