所谓同直径延末计算法,就是将同一中央直径,不同材长的原条,计算其延末总长度,一次从材积表中查得,而无需分材长查阅材积。这种计算方法完全能够满足统计等方面的要求。一、材积表的编制采用同直径延末计算法时,应先行编制材积速算表,其方法是:先计算原条断面积,然 The so-called same diameter end-of-delay calculation method, is the same central diameter, different length of the original article, calculate the total length of the end of delay, one from the volumetric table check, without the need for sub-material length for reference volume. This method of calculation can fully meet the statistical requirements. First, the volume table using the same diameter at the end of the calculation, the system should be compiled before the speedometer, the method is: first calculate the original section area, of course
