摘　　要：本文从断裂力学的角度探讨了纸张发脆的本质,提出了用脆性常数B来反映纸张脆性的大小。结果表明,B值较客观地反映了纸质发脆的程度。According to fracture mechanics concepts, the essence of paper brittleness has been approached in this paper. Brittle con-stant-B is introduced to evaluate paper brittleness. The results show that B-value can objectively 'measure the degree of paperbrittleness.
