从表1中抽取回归系数得到回归方程如式（4），回归式的负相关系数R=0.204，拟合优化系数 =0.042，变量4.2%，拟合优度良好。方差检验F值对应的概率P值为0.002，小于显著度0.005，说明屈服强度和元素成分之间存在显著的线性关系。在单个元素中成分之间存在显著的线性关系。在单个元素中C、Mn、Si和V的P值小于显著度0.005，说明这四个化学元素对钢筋的屈服强度存在显著性的相关关系。

結果 (英文) 1:

Extract the regression coefficient regression equation is obtained from table 1 (4), returning a negative correlation coefficient R=0.204, fitting the optimum coefficient = 0.042, variable 4.2%, goodness of fit good. Probability p value for variance f value is 0.002, 0.005 less significant degree, that yield strength and there was a significant linear relationship between the elements. There was a significant linear relationship between the components in a single element. In a single element c, Mn, Si and v p-value is less than the dominance of 0.005, shows how these four elements reinforced yield strength significantly correlated.

Decimation regression coefficient regression equation such as formula (4) from Table 1, the negative correlation coefficient regression formula R = 0.204, fitting optimization coefficient = 0.042, 4.2% variable, the goodness of fit is good. Variance test F value corresponding to the probability P value of 0.002, significantly less than 0.005, indicating that yield significant linear relationship between the intensity and the elemental composition. There is a significant linear relationship between components in a single element. P value of single elements C, Mn, Si and V significantly smaller than 0.005, indicating that the four chemical elements there was a significant correlation between the yield strength of steel.

In Table 1, the regression coefficients are obtained, such as the formula (4), the negative correlation coefficient R=0.204, the fitting optimization coefficient =0.042, the variable 4.2%, and the goodness of fit is good. The probability F value of the variance test P value is 0.002, which is less than 0.005, which indicates that there is a significant linear relationship between the yield strength and element composition. There is a significant linear relationship between the components in a single element. The V value of C, Mn, Si and P in a single element is less than 0.005, which indicates that the four chemical elements have significant correlation with the yield strength of the steel bar.
