【摘要】 主要对回归方程检验混凝土非破损的检测精度进行了研究,通过分析各回归方程的相对标准差、平均相对误差、离散性,采用上述各项指标来表示回归方程的强度误差或回归精度是不准确的,应用更精确的物理概念加以解释。更多还原

【Abstract】 The regression equation of examining concrete non-breakage precision is researched.Through analyzing the relative standard deviation and the average relative error and divergence of each regression equation,the expression on intensity error or regression precision for the regression equation with the above factors is inaccurate, which needs the more precise physical conception to explain.更多还原
