摘    要:在原木检量评等中,有的不易快速计算,本文提供了一些简捷方法。例如在长短径平均值计算中采用“短径加长短矩差之半”;在计算缺陷限度时采用“扩倍与折半”的方法,在心腐限度计算中采取面积比与直径比的换算法及dx/dj控制挡位法。

关 键 词:简捷计算  原木检验  等级评等

Abstract:During log measurement and grading, it is difficult to calculate quickly sometimes. The paper provided some simple and direct means. For example, when calculating the average numerical value of long diameter and short diameter, we can use the method of "short diameter plus half of the difference between long diameter and short diameter". When calculating defect limitation, we can use the method of "double and reduce by half", when calculating inner decay, limitation, we can use the conversion method of area ratio and diameter ratio and dx/dj controlling grade method.
Keywords:Simple and Direct Calculation  Log Measurement  Grade Evaluation
