为了提高木材检尺、调拨中的材积计算效率,我们设计了一种“圆盘活动材积表”。这种材积表较之书本的材积表,有使用方便,查阅快,准确性高等优点。原理: 圆盘活动材积表和普通材积表一样,仍然是一种把许多计算结果按座标排列在表格内的计算表。即用表格的方式,把各种需要的计算结果(原木的材积),预先排列在相应经纬线的交叉处,使用时只要在表中查到按纬线排列的已知数原木的长度,再查到按经线排列的另一个已知数原木的小头直径,从这两个已知数的延伸线的交叉口上,便可查到未知数原木材积。不同的是,圆盘活动材积表脱离了固定的表格形式,可以按需要活动组合,大量精减了表页的重叠,查阅时不须反复查对表页,从而提高了查阅速度。另外,圆盘活动材积表的读数是在一个特定的“窗口”显示,这样也就提高了查阅的准确性。
In order to improve the wood detection, transfer volume calculation efficiency, we have designed a “disk activity volume table.” This volume chart than the book’s volume chart, easy to use, access to fast, high accuracy and so on. Rationale: The disk activity volume table, like a normal volume chart, is still a calculation table that tabulates the results of many calculations in a table. That is to use the form of the form, the various needs of the calculation results (timber volume), arranged in advance at the corresponding intersections of latitude and longitude lines, as long as the use of the table to find by the latitude of the known number of logs arranged length and then check From the small head diameter of another known log in warp, the unknown log volume can be found from the intersection of these two known extension lines. The difference is that disc activity volume chart out of the fixed forms, activities can be combined as needed, a substantial reduction in the overlap of the table page, access without having to repeatedly check the table page, thereby improving access speed. In addition, disc readings of the active volume table are displayed in a specific “window”, which also improves the accuracy of the inspection.
