摘　　要：对杨木APMP采用了几种不同的无机酸酸化后处理，研究对比了酸化对纸浆白度以及白度稳定性的影响，探讨了人工老化后纸浆(未酸化处理浆及草酸酸化处理浆)物理强度的变化情况。Some kinds of acid were used individually to acidify Poplar APMP, and comparison of effect on pulp's brightness-stability improvement were investigated. It was shown that, the brightness and brightness-stability improvement effect by acidification were different from type of acids. Oxalic acid could enhance the pulp on both brightness and photo-stability, as well as inhibit yellowing by dry－or wet-heating substantially. Among four kinds of acid selected, oxalic acid did best. The pulp's physical strength properties, before and after aging, were measured.
