采用电法CT技术探查树木内部结构

为探讨直流电法应用于树木内部结构探测的成像效果,通过直流电法层析成像技术对不同种类的树木进行了检测实验研究。运用并行电法进行数据采集,利用弧度修正系数对电性参数进行了修正,获得了较为理想的树干电阻率剖面。三种树木电性剖面对比发现,不同材质的树木电阻率值差异明显,且树干断面电阻率分布整体表现为里高外低的特征。电阻率分布特性可为树木健康状况诊断提供相关技术参数。

Cellular Structure Detection of Tree by Direct Current CT Technology

With direct current CT technology,the detection experiment among different tree species has been carried out for the sake of studying the imaging results of inner structure of tree trunks.Ideal resistivity distribution profiles have been obtained by the process of data collecting with the Network Parallel Galvanic Exploration System initially and curvature correction for modifying electrical parameters then.By contrast,the conclusion can be drawn that there’s a large variation range among three kind of trees in resistivity.Besides,the internal electrical distribution of tree trunk is that resistivity of the trunk profile is higher inside,and lower outside respectively.Related technical parameters can be provided by resistivity distribution characteristics for diagnosing health symptoms of trees.
