摘要
In this paper, the targets evaluating wood collapse defect was studied which included, three targets of collapse depth, collapse factors, volumetric shrinkage rate, and their measuring methods. The main point of 3 targets and the relationship of 3 targets were analyzed when collapse was evaluated. Based on the study of aspen wood collapse, collapse was classified,proceeding to show that different collapse should use different evaluating targets. The collapse properties of different standard Daqing Aspen were studied using above evaluating targets and classification methods.
