In chapter 5, the concept of zero-span tension known in papermaking area is for the first time introduce to wood science area to explore in-tree variation of longitudinal tensile strength of tracheids and its main influencing factors. In chapter 6, composite micromechanics and classic laminated theory are used to make a comprehensive and detailed analysis of the main influencing factors of mechanical properties of tracheids cell wall. Some experimental results acquired in the foregoing chapters are explained successfully. Results were summarized as follows: Mechanical characteristics of wood at micron scale: 1 At micron scale, the longitudinal mechanicai behavior of wood microtome section differs greatly from that of wood with normal size.
