<正>根据木材加工行业的特点，确定江苏木材加工企业的投入产出要素，基于相关原则选取江苏省杨树产业项目区的32家木材加工龙头企业作为样本，建立Cobb-Dauglas生产函数模型，以此对江苏木材加工产业的规模效率状况进行评价。

The thesis adopted the mode of"cantalever grider" freeness end, mensuratcd dy namic elasticity model and damp ratio of HDF and OSB test materials. For illuminate correctness of the dynamic testing method, the paper showed static elasticity model results of HDF and OSB test materials. The results showed that its dynamic elasticity model and static elasticity model complexions were consistent. It incarnated the dynamic testing merits on speediness, convenience and good repetition etc.
