该研究利用X射线测定三倍体毛白杨木材各无性系气干密度 ,通过适当的数学模型 ,利用计算机可视化技术对木材密度的分布进行可视化分析 ,得到了木材横切面密度二维分布图 .图形清晰 ,直观性强 ,并可做各种角度、各种颜色、空间与平面、局部与整体的各种变换 ,这对于深入了解木材材性是十分有益的 .该文同时分析了三倍体毛白杨各无性系木材密度的差异与变化率等特点 . In this study, the air-dry density of clones of Triploid Populus tomentosa was determined by X-ray. Through the appropriate mathematical model, the distribution of wood density was visualized by computer visualization technology, and the two-dimensional distribution of cross-sectional density of wood was obtained. , Intuitive and can do all kinds of angles, a variety of colors, space and plane, local and overall transformation, which is very useful for in-depth understanding of wood properties.This paper also analyzed the triploid poplar Clonal wood density differences and the rate of change and other characteristics.
