尾叶桉U6林分平均木、优势平均木、最小平均木木材吸水率差异性检验

Difference test on timber water absorption rate of stand average wood,dominant average wood and minimum average wood of E.urophylla clone u6

主要通过取用直接数据法和对数方法对尾叶桉U6(E.urophylla U6)林分平均木、优势平均木、最小平均木木材吸水率作差异性(t)检验,对比(U)检验和方差(F)检验。检验结果直接数据法和对数方法这两种检验方法的结论一致,检验结果的数据表明:三者两两之间的吸水率无明显差异,平均相对误差在百分之一左右。即三者同属于一个随机变数正态分布总体。

The timber water absorption rate difference test （t）,contrast test （U） and variance test （F） of E.urophylla clone u6 stand average wood, dominant average wood and minimum average wood were made by means of direct data and logarithmic method. The same conclusion was drawn by the two methods. There is no significant difference among the three absorption rates and the average relative error is 1% or so namely they belong to the entirety of random variable of normal distribution.
