【Abstract】 Based on the general regular simplex interest region of （q-1）-dimensions and multi-linear polynomial model, optimal designs for generalized polynomials in q variables were applied, the design of extreme-apex and the design proposal were adopted and 16 experiment data were chosen to establish cubic multi-linear polynomial regression equation of the penetration nature with two additives:f（x₁,x₂,x₃）=-172.59+5 968.91 x₁-5 830.57 x²₁+2 504.44 x³₁-32.490 5 x₂. The coordinated effect and confrontation effect and addition effect, and change wax of the penetration nature were studied. The result shows that the plant additive has outstanding effects on the wax penetration nature, not animal additive. The regression equation can be applied to calculate physical characteristic of the wax penetration. The conclusion will have reference value on the study of wax new products.更多还原
