钢绞线最大力的伸长量怎么检查呢(hW^P„—¡€†bbs.3c3t.com¹ï;Uœé2'Pê

附  录  A(hW^P„—¡€†bbs.3c3t.com¹ï;Uœé2'Pê
使用下列公式计算光缆用镀锌钢绞线的弹性模量(E)见公式(1)。(hW^P„—¡€†bbs.3c3t.com¹ï;Uœé2'Pê
E=（L0* △F）/（S*△L）………………………(1)(hW^P„—¡€†bbs.3c3t.com¹ï;Uœé2'Pê
式中：E——光缆用镀锌钢绞线弹性模量，GPa；(hW^P„—¡€†bbs.3c3t.com¹ï;Uœé2'Pê
   △F  ——载荷增量，N；(hW^P„—¡€†bbs.3c3t.com¹ï;Uœé2'Pê
    S  ——光缆用镀锌钢绞线金属断面积，mm2；(hW^P„—¡€†bbs.3c3t.com¹ï;Uœé2'Pê
    △L  ——载荷增量为△F时的伸长量，mm：(hW^P„—¡€†bbs.3c3t.com¹ï;Uœé2'Pê
     L0 ——原试样长度，mm(hW^P„—¡€†bbs.3c3t.com¹ï;Uœé2'Pê

楼主提供的计算表似乎说明其弹模与钢绞线的引伸计标距、钢绞线的屈服负荷\试样长度等没什么关系一样(hW^P„—¡€†bbs.3c3t.com¹ï;Uœé2'Pê
