摘　　要：本文通过对侧流式圆网槽的研究和使用,发现控制纸料速度就能有效地改善成纸的纵横向抗张强度比,只要增设浆流均布限速板,便能灵活地调节成纸的纵横向抗张强度比。成纸纵横向抗张强度比最低的可达到1.007:1,超过了长网纸机的水平,最高的在21.68:1以上。生产纸的定量由35g/m^2至100g/m^2,匀度均达到要求。Productive practice and study of lateral flow vat showed that the paper's tensile ratio of machine—direction to cross—direction can be easily adjusted by employing a flow velocity reg- ulating board.The papers formed on lateral flow vat cylinder machine can have the tensile ra- tio as low as 1.007:1(which even lower than that of fourdrinier papers),and as high as 2.68:1.Applying the lateral flow vat to manufacture some types of papers which have dif- firent basis weight from 35g/m^2 to 100g/m^2,good formation was achieved.
