各行数字含义（以最后一行为例）：
槽250x80x20x3.0：
截面高度H=250mm；
截面宽度B=80mm；
卷边宽度C=20mm；
厚度t=3mm；
Y轴距离z0=21mm；
偏心距e=51mm；
截面面积A=1229mm2；
惯性矩Ix=10917690mm4；
惯性矩Iy=919850mm4；
截面模量Wx=87342mm3；
截面模量Wy=15591mm3；
回转半径ix=94.3mm；
回转半径iy=27.4mm；
抗扭惯性矩It=3690mm4；
扇形惯性矩Iw=10465300000mm4；
单位重量=A*7850/1000000=9.648Kg/m；
他们说的都不准确，c型钢有个回弯，c180*70*20*2.5的重量应该是：
[（180+70+70+20+20）-4*2.5]*0.0025*7.85=6.87kg/m
也就是理论展开，再减去4倍的厚度，然后再乘厚度和密度
