利用计算机对昆明重工集团生产中积累的ZG35钢力学性能数据进行了回归分析。建立了性能之间显著性较高 (α =0 0 1)的回归方程 ,益于辅助设计 ,指导生产。
The regression analysis of the mechanical properties of ZG35 steel accumulated in the production of Kunming Heavy Industry Group was carried out by computer. A regression equation with high significance (α = 0 0 1) was established to benefit the design and guide the production.
