摘　　要：This study uses two different mathematical models and gets two dimensional graphs of longitudinal and tangential section wood density at the same time by the radial wood density data measured by X_ray. The graph is direct and clear. It can be used to analyze the distribution and difference of wood density. It can also be done various kinds of transformation, including different angle, different colors, space and plane, part and entirety. This develops the visible analysis of wood density. Next the distribution of wood density of veneer will be simulated by new mathematical model and radial wood density data.This study uses two different mathematical models and gets two dimensional graphs of longitudinal and tangential section wood density at the same time by the radial wood density data measured by X_ray.
