Effect of biological pretreatment with Trametes vesicolor on the enzymatic hydrolysis of softwood and hardwood

Orthogonal cooking experiments of hardwood chemical pulp were carried out by adding cooking agent (Busperse) based on the traditional cooking method.

Influence of the technological parameters upon the warp of both veneered plywood with the maple;

The results showed that,because of viscous-elastics of wood,there is deficiency choosing minimum and maximum values in measurement of wood modulus of elasticity and the revised coefficient of values for wood hardness of side section when half pressure were loaded is not right,and the improved methods were made suggestions.
