This paper presents a model that describes the change in magnitude of bow and crook between two moisture contents below the fiber saturation point. The model shows that the variation in the longitudinal shrinkage coefficient over the cross section and along the stud could explain most of the change in bow and crook in the studs. It was possible to identify evenly curved bow and crook, as well as S-shaped bow and crook. The results show that the model predicts changes in bow better than changes in crook.
參考答案:这纸呈现一个在纤维浸透点下面描述在二湿气内容之间的弓和钩的在大小方面的改变的模型。 模型表示在交叉的区段上的纵观收缩系数的变化而且沿着图钉可以解释在图钉中在弓和钩方面的大部份的改变。 平均地识别弯弓和钩、连同 S 形的弓和钩是可能的。 结果表示模型预测在弓方面的改变比变化好 i
