摘要/Abstract

摘要： 用缆索起重机测量了红松、云杉、冷杉、椴木、杨木、桦木、栬木和榆木等树种原条的重心位置。以数理统计理论和微机分析确定了原条重心距的变化规律与变动区间

关键词: 原条重心, 原条重心距, 原条重心距区间

Abstract: The article measures the gravity center locations of tree stems with cable crane, the species of tree stems including korean pine, drangon spruce, faber fir, linden, poplar, birch, elm, etc. . It analyses and determines statistically the varing laws and limits of tree stem gravity center locations withcomputer.

Key words: Gravity center of tree stem, Gravity center location of tree stem, Limits of gravity center location
