1.
We use the dimension-reduction algorithm to make the apparent density function of concrete to change from multi-dimensional function to one-dimensional function,use the least square method to get correlation coefficient,use the number line method to choose the experiment,use the contouring method to get the extremum,then this extremum is the optimal mix proportion of concrete.
采取普通试验仪器和设备,把优选法用于混凝土配比试验中,采用“降维法”使混凝土表观密度函数从多维函数降为一维函数,用最小二乘法求相关系数,按单因数折纸法优选试验点,三级配采用等高线法求极值,该极值就是混凝土的最佳配合比。
