原木材积表

原木材积表（本标准适用于所有树种的原木材积计算）原木材积表本标准适用于所有树种的原木材积计算。

1. 检尺径自4~12cm的小径原木材积由公式V=0.7854L{D+0.45L+0.2}2 ÷10000 确定2．检尺径自14cm以上的原木材积由公式V=0.7854L{D+0.5L+0.005L2+0.000125L ·（14-L）2·（D-10）2÷10000 确定。

两式中：V 材积，m3；L 检尺长，m；D 检尺径，cm.3. 原木的检尺长、检尺径按144.2-84 《原木检验尺寸检量》的规定检量。

4. 检尺径4~6cm的原木材积数字保留四位小数，检尺径自8cm以上的原木材积数字，保留三位小数。

国标原木材积表一、引言国标原木材积表是一项用于评估和计算原木材积的标准表格。

在木材加工和使用过程中，正确评估原木的材积是非常重要的，因为它直接影响到原木的价值和利用率。

国标原木材积表的制定旨在提供一种标准化的计算方法，以便对原木进行统一的评估和交易。

二、国标原木材积表的概述国标原木材积表是根据国家标准制定的，其基于国内外广泛采集的原木材积数据，并结合了统计学和数理统计等方法进行处理。

该表格主要包括了原木的尺寸、体积计算公式以及不同材质的校正系数等内容。

它不仅适用于国内的原木材积计算，还可以作为国际交易中的计量标准。

2.1 原木尺寸的分类国标原木材积表中，原木尺寸被分为直径和长度两个参数。

直径一般指原木的最大外径，长度则表示原木的整体长度。

按照国家标准的规定，原木的尺寸采用米为单位。

2.2 体积计算公式为了计算原木的体积，国标原木材积表提供了相应的计算公式。

根据原木的尺寸参数，可以选择不同的公式进行计算。

一般常用的计算公式有立方体积计算公式和柯式加权体积计算公式等。

在计算体积时，需要注意尽量选择与原木形状相匹配的体积计算公式，以提高计算精度。

2.3 材质校正系数不同材质的原木在计算体积时，需要考虑到其密度的差异。

为了对不同材质的原木进行修正，国标原木材积表给出了相应的校正系数。

通常，材质校正系数是通过前期的实验测定和统计分析得出的，可以准确地反映不同材质原木的实际体积。

三、国标原木材积表的应用国标原木材积表在实际应用中具有重要意义。

下面列举了一些应用场景：3.1 原木交易在原木交易过程中，买卖双方需要根据原木的材积确定交易价格。

国标原木材积表提供了一个公平、科学的计算方法，可以作为交易的依据，避免因计算方法不统一而导致的纠纷。

3.2 木材加工在木材加工过程中，合理评估原木的材积可以提高加工效率和材料利用率。

国标原木材积表为木材加工企业提供了一个标准的计量工具，可以准确地计算出原木的材积，从而更好地指导生产工艺和设计工作。
