25、，可先得出整十位數(shù)根數(shù)的材積數(shù)，然后再加上直接查得的個位數(shù)根數(shù)的材積數(shù)而得。  二、對GB4814-84原木材積表的說明1、GB4814-84原木材積表的規(guī)定本標準適用于所有樹種的原木材積計算。（1）檢尺徑自4-12cm的小徑原木材積由下式確定：  V=0.7854L(D+0.45L+0.2)²÷10000  式中：V材積(m³)；  L檢尺長(m)；    D檢尺徑(cm)。（2）檢尺徑自14cm以上的原木材積由下式確定：  V=0.7854LD+0.5L+0.005L²+

26、0.000125L(14-l)²(D-10)²÷10000（3）原木的檢尺長、檢尺徑按GB144.2-84原木檢驗  尺寸檢量的規(guī)定檢量。（4）檢尺徑4-6cm的原木材積數(shù)字保留四位小數(shù)，檢尺徑自8cm以上的原木材積數(shù)字，保留三位小數(shù)。2、GB4814-84原木材積表中的附錄（圓材材積計算公式）的規(guī)定（1）檢尺長超出原木材積表所列范圍而又不符合原條標準的特殊用途圓材，其材積按下式計算：  V=0.8L(D+0.5L)²÷10000（2）圓材的檢尺長、檢尺徑按GB144.2-84原木檢驗  尺寸檢量的規(guī)定檢量。 檢尺徑，按2cm進級；檢尺長的進級范圍及長級公差允許范圍由供需雙方商定。（3）缺陷限度及分級標準由供需雙方商定。（4）地方煤礦用的坑木材積按下表計算： 檢  尺  徑(cm)檢  尺  長(m)1.41.61.8材      積
