摘　　要：通过对解析木材料的研究,得出树木生长的拟合降水量经验方程,即生长方程和阻力方程,经过这2个方程的融合而得到平衡精度。解析木区段长度相同,只要样本数量相同,起始年龄相同,这一平衡精度是完全相等的。解析木2 m区段的树径项目表现与1 m区段表现差异较大,而降水量的平衡精度在同等条件则表现比时间因素的平衡精度相对要高。Through the study of the analysis of wood materials,the empirical equations of fitted precipitation for tree growth are obtained,that is,the growth equation and the resistance equation.After the fusion of these two equations,the balance accuracy is obtained.The length of the analytical wood segment is the same,as long as the sample with the same number and the same starting age,the balance accuracy is exactly the same.The performance of the tree path project in the two-meter section of the analysis tree is significantly different from that in the one-meter section,and the balance accuracy of the precipitation under the same conditions is relatively higher than that of the time factor.
