In order to analyze the airborne LiDAR data corresponding to single trees and stand heights in the forestry area, we set up samples to measure tree heights of Alnus formosana, Cryptomeria japonica, and Chamaecyparis formosensis in the Alishan area. We build the Canopy Height Model based on the data from the airborne laser scanning system. Single Tree heights were estimated by averaging the CHM values within a 0.5m radius, and six different sizes of sample stands (5×5, 10×10, 12.5×12.5, 15×15, 17.5×17.5, and 20×20) were set up to extract the average heights within the area as the calculated value.

本研究於阿里山地区设置样区，针对台湾赤杨、柳杉、红桧等树种进行立木树高之量测，配合该样区之空载光达影像资料，建立树冠高度模型(Canopy height model， CHM)，探讨空载LiDAR在森林地区对於单木树高与林分高的量测情形；单株立木高系以样区立木位置为中心，萃取0.5 m 圆形环框范围内之CHM平均值为其推估值；光达林分高则以6种林分面积(5 m×5 m、10 m×10 m、12.5 m×12.5 m、15 m×15 m、17.5 m×17.5 m、20 m×20 m)萃取范围内之CHM平均值为其推估值。

Results:Single gast rointestinal leiomyosarcoma in all cases was found,and X-ray feature was as fol lowing:there was a filling defect of round or oval shape or a mass in intralumin al type (4 cases),there was a large,irregular ulcerative crater in the center of tumor.

结果：均为单发病例，X线片上腔内型4例，表现为圆形、半圆形充盈缺损或软组织肿块，肿瘤中心出现不规则的龛影。

An image acquisition system snapping three instantaneous images at the same time with a color image board has been designed, it can obtain homochromy laser spot images at difference orientation in ICF experiment.
