Practical wood volume table and short raw wood product table
In order to check the volume of the logs, in addition to the length of the log gauge with 0.52m, a professional timber volume table was prepared, and some improvements were made to the layout of the table, that is, the original 4 diameter grades were compiled into 1 Combinations, combinations and combinations of the polar volume are used to match the body words, instead of the current combination of the product, the volume of the double centimeters of horror is arranged by the arrangement of the gray bottom, so that the single centimeter broker and the double centimeter The volume of the broker is clearly differentiated. This article introduces the common wood volume table and short raw wood product table. This standard applies to the calculation of the original wood volume of all tree species. 1. The original wood volume of the small diameter of the gauge diameter from 4 to 12 cm is determined by the formula V=0.7854L (D+0.45L+0.2)2÷10000. 2. The original wood product with a diameter of 14 cm or more is determined by the formula V=0.7854L [D+0.5L+0.005L2+0.000125L(14-L)2×(D-10)]2÷10000. In the two types: V---volume, cubic meters; L---the length of the gauge, m; D--- gauge diameter, cm.

(1) The accumulation count of single or less than 10 logs, ordinary strips, special sawn timber and ordinary sawn timber can be directly found in this manual.
(2) Counting counts of 10, 20, 30... whole ten-digit logs, original strips, special sawn timber, and ordinary sawn timber, one or two of which can be detected first. The number of three volumes of ..., then the decimal point is shifted to the right by one (ie, 10 times).
(3) The accumulation count of 10 or more logs with single digits, original strips, special sawn timber and ordinary sawn timber, the number of volumes of the whole tens of digits can be obtained first, and then The number of volumes of the number of single digits directly found is obtained.
