A sin that seems small in the common beam of the world , may be very great in the scales of the sanctury 按世俗的标准这似乎是一次无关紧要的过失，而在圣殿的天平上则可能会是事关重大的。

The research is that : after the same cyclic number of loading times , the steel stress of reinforced beams was much smaller than that of common beam ; the deflection of reinforced beams was decreased by 40 % - 50 % , therefore , the anti - transformation of the reinforced beams is enhanced greatly 研究发现：经过相同次数的疲劳荷载作用后，完好加固梁的钢武汉理工大学硕士学位论文筋应变小于未加固梁，加固梁的变形减少了40 %一50 % ，加固梁的疲劳寿命提高t60 % ~ 80 % 。
