摘要：
Properties of paper are controlled by modeling the effect of at least one variable (fD) of the paper dryer section on the paper moisture (Moi) and the effect of the stock flow (Fts) and/or stock composition and the flow of retention agent (Fra) on the paper moisture (Moi). By means of the modeling, the paper moisture (Moi) is adjusted by simultaneously controlling at least one variable (fD) of the paper dryer section, the stock flow (Fts) and the flow of retention agent (Fra).
