摘要
对原木周边部分最大短锯材材积计算式和最佳锯剖位置探索的结果。最大短锯材材积计算式为: V=(43^(1/2)(R^2-a^2)^(3/2))/(R^2-r^2)(a-b)L最大短锯材外材面的最佳位置为: a=(3b±(9b^2+16R^2)^(1/2))
The estimation equation for the maximal volume of short sawn timber from the peripheral part of a log and the optimal sawcut position were approached. The estimation equation for the maximal volume of short timber is as follows.The optimal sawcut position on the outside of short sawn timber can- be determined by the following equation.
