碩士 === 國立嘉義大學 === 木質材料與設計學系研究所 === 102 === This research softwood and hardwood through varying degrees of carbonization, changes observed samples of each species tissue structure, samples high temperature carbonization machine (high temperature anaerobic combustion) later, found that some characteristics of the sample itself, such as color, odor , there will be significant changes in the size, color, black and will be reflective of the change in size will be reduced, the sample becomes easy friability, but its appearance, distinguishing characteristics, such as poresity arrangement, ray ,annual ring etc., will be kept for them, these distinguishing characteristics are not apparent after carbonization suffered damage. Can be do according to these characteristics and are not preserved carbonization wood compared ,charcoal can investigate academic, engineering purposes, Wood trade above can discriminate based on a simple, easy identification of wood charcoal Annals as the need for identification use.
