新城金矿充填体弹性模量的正交回归试验研究
Under different rev and loads , the optimal diesel / alcohol proportion would be different . in order to find out the change rule of optimal diesel / alcohol proportion , an orthogonal regression rotating experiment of three factors ( rev , diesel / alcohol proportion and load ) at five levels has been carried out . based on the experiment , four regression equations including energy consumption , soot emission , noise level , and power equations concerning the three factors have been established
在性能试验的基础上，还进行了三因素五水平的二次正交回归旋转组合试验，建立了能耗率、烟度、噪声、功率与转速、酒精掺烧率及负荷率之间的回归模型，通过分析可知，这些模型具有较高的可信度；利用这些模型，本文最后对不同工况下的最佳酒精掺烧率进行优化分析，并利用正交多项式回归，求出了最佳掺烧率与转速、负荷之间的回归模型，该模型在今后的深入研究中将起到一定的指导作用。
