中华人民共和国国家标准——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 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。检尺长：指检量木材实际长度时，按照某项标准的规定经过进或舍之后的尺寸检尺径：指检量木材直径时（原木检量小头直径），按照某项标准的规定经过进或舍之后的尺寸检尺径，cm检尺长，m2.02.22.42.52.62.83.03.23.4材积，m34681012141618202224262830323436384042440.00410.00790.0130.0190.0270.0360.0470.0590.0720.0860.1020.1200.1380.1580.1800.2020.2260.2520.2780.3060.3360.00470.00890.0150.0220.0300.0400.0520.0650.0800.0960.1140.1330.1540.1760.1990.2240.2510.2790.3090.3400.3720.00530.01000.0160.0240.0330.0450.0580.0720.0880.1060.1250.1460.1690.1930.2190.2470.2760.3070.3400.3740.4090.00560.01050.0170.0250.0350.0470.0600.0760.0920.1110.1310.1530.1770.2020.2300.2580.2890.3210.3550.3910.4280.00590.01110.0180.0260.0370.0490.0630.0790.0970.1160.1370.1600.1850.2110.2400.2700.3020.3350.3710.4080.4470.00660.01220.0200.0290.0400.0540.0680.0860.1050.1260.1490.1740.2010.2300.2600.2930.3270.3640.4020.4420.4840.00730.01340.0210.0310.0430.0580.0750.0930.1140.1370.1610.1880.2170.2480.2810.3160.3530.3930.4340.4770.5220.00800.01470.0230.0340.0470.0630.0810.1010.1230.1470.1740.2030.2340.2670.3020.3400.3800.4220.4660.5120.5610.00880.01600.0250.0370.0500.0680.0870.1080.1320.1580.1860.2170.2500.2860.3240.3640.4060.4510.4980.5480.59946485052545658600.3670.3990.4320.4670.5030.5410.5800.6200.4060.4420.4790.5180.5580.5990.6420.6870.4470.4860.5260.5690.6130.6580.7050.7540.4670.5080.5500.5940.6400.6880.7370.7880.4870.5300.5740.6200.6680.7180.7690.8220.5280.5740.6220.6720.7240.7770.8330.8900.5700.6190.6710.7240.7800.8380.8980.9590.6120.6650.7200.7770.83...
