    THEORETIC CALCULATION OF CROSS-SECTIONAL AREA OF INTERNAL-THREAD SHAPED STEEL TUBE

    • 摘要: 根據(jù)內(nèi)螺紋異型管縱截面不直觀參數(shù)來計算其橫截面面積的理論計算方法，可大大減化生產(chǎn)中取樣、刨標(biāo)樣、稱重等多項程序，且與標(biāo)樣稱重計算法所得數(shù)值相差不大。該計算方法切實可行。

       

      Abstract: The method for theoretic calculation of the cross-sectional area of the internalthread shaped tube on the basis of the tube’s longitudinal-section non-oclar parameters can significantly simplify the operation procedures of sampling, machining of reference specimen and weighing, etc., while the calculation result is close to that of the reference specimen-weighing method. The said method is very practical.
