采用奥氏气体分析法测定常量气体组份时,量气管刻度不准确、梳形管以及量气管上部支管所造成的分析误差,已为实践所证明(见表1)。要避免这些因素所造成的分析误差,就必须进行校正。我们所采用的校正方法,不同于残气冲洗法,但同样可以获得稳定准确的结果,只要对奥氏气体分析器进行正确的校正,也不必将习惯的样气冲洗改为残气冲洗。是一种既准确又简便的校正方法。 The analytical errors caused by the inaccuracy of the gas trachea, the comb-shaped tube, and the upper branch of the gas trachea when austenitic gas analysis is used for the determination of constant gas components have been demonstrated by practice (Table 1). To avoid the analytical errors caused by these factors, it must be corrected. The calibration method we use is different from the residual flushing method, but it is equally possible to obtain stable and accurate results. It is not necessary to change the customary sample flush to residual flushing, as long as the correct calibration of the austenitic gas analyzer is performed. Is an accurate and easy method of calibration.
