生长锥钻入树干,特别是较大树干,常常会错过髓心,因此需要估计树木髓心的位置。在林业文献中尚没有论述过偏心生长年轮宽度的计算方法。本文就偏心生长圆盘的半径计算,提供一种简便的方法。阿卜里魁斯特于1958年曾利用一种叫做“髓心位置标定”的装置估计偏心树干究竟 Drilling the cone into the trunk, especially the larger trunk, often misses the pith, so the location of the pith is estimated. In the forestry literature has not discussed the calculation of the growth of eccentric ring width. This article provides a convenient method of calculating the radius of an eccentric disk. In 1958, Aberqusetter used a device called “centripetal position calibration” to estimate the eccentric trunk
