In this study, plantation of Chinese-Fir and Masson-Pine for the object, the Zero-span tensile strength of tracheids, in-tree variation and the effect of moisture content of the Chinese-Fir and Masson-Pine were researched, on the other hand on the plantation of Chinese-Fir and Masson-Pine for high-temperature heat-treated and tested the chemical components, crystallinity, elastic modulus of tensile in vertical direction of small sample. The focus of study is that treatment-temperature and treatment-...
