摘要：

A statistical model for tensile strength development based on the requirement of a few successful loading cycles to treat fibres was applied to an industrial refiner. The findings for a normal range of refining intensity concur with those found in an earlier study for compression refining. These findings suggest that the main role of multiple bar crossings in refining chemical pulp is to impose one of a few loading cycles on many fibres rather than to impose many loading cycles on each fibre, In short, the role is one of overcoming heterogeneity of treatment rather than imposing fatigue weakening.
