| Abstract: | Study of the variation law and （permanent deformation rate） is the core factors and mechanism influencing wood wood density, softening methods, chemical mechanism of wood longitudinal compressive plastic-elastic properties and PDR of wood longitudinal compression and multi-dimensional bending technology. The longitudinal compression ratio and PRD are analyzed in terms of wood species, components, relative crystallinity and compression speed. |
