Abstract

PURPOSE: To enable to revise the set value of control variable (the product of an oxygen partial pressure difference and the corrected value of an aerated gas amount) without directly measuring dissolved oxygen by measuring the proportional constant of the differsolved oxygen concentration on the basis of the secular changes of aeration amount and oxygen partial pressure difference.
