Research and Development of the Method for Testing Wood Density
Density is an important indicator of wood property which reflects the material, defects, mechanical property and technologic property of wood.How to explore the reasonable testing method and measure the density of tested wood effectively and quickly is always the direction of researchers.The wood density testing methods in current use and research were classified from the perspective of detection mechanism as traditional weighting method, density detection method based on mechanical force and density detection method based on ray.The research and development of these methods especially the latter two ones were introduced and summarized in this paper, which may provide some reference for the work of relevant researchers.
