摘要
通过一定数量的试块和试件 ,得到抗压强度和后装拔出力 ,利用线性回归找出二者的相互关 系。线性关系良好 ,其相对误差为 5 .8% ,相关系数为 0 .99。该工作完善了检测技术、拓宽了 实践应用范围。
The authors obtain compression strength and pulling out post-insert force by a number of briquettes and test specimens and find out the relationship between them by linear regression. If the linear relation is good,their relative error is 5.8 percent,the concerning coefficient is 0.99.The experiment perfects the detecting technique and widens its application.
