摘要
本文首先通过试验得出钢材抗拉强度与其里氏硬度之间的对应关系 ,并用多种方法对试验数据进行线性和非线性回归分析 。
In the paper,based on the experiment results the transformation relations between Leeb-hardness and tensile strength are obtained through linear regression and nonlinear regression.The feasibility of applying the relation to check the strength of fired structural steel in site is discussed.
