摘　　要：本文以PAGE方程为基础,结合光散射系数测量技术,并以针叶木为原料,研究了水分含量对纤维剪切结合强度和相对结合面积(Relative Bonded Area)RBA的影响。实验表明,一定的水分含量下剪切结合强度达最大值,RBA随着水分和打浆度的增大而增大。Based on the PAGE equation and with the aid of light scattering coefficient technique, a new method to determine fiber - fiber shear bond strength was presented in this paper. The effects of moisture content on fiber - fiber shear bond strength and fiber relative bonded area （RBA） were investigated with bleached Canadian kraft soft- wood pulp. The results showed shear bond strength realized the peak value at appropriate moisture content, and RBA increased with moisture content and beating degree increasing.

关 键 词：水分含量 剪切结合强度 RBA
