【Abstract】 A new method to determine optimal operating technical parameters in the process of preparing nano materials is put forward,as an example of nano-Fe₃O₄ powder by hydrothermal method.Based on the quadric orthogonal rotation regression design method,the index value of each experiment design is achieved and the quadratic programming mathematical model is presented.The experments show that workload is reduced,and the calculating procedure of the optimization mathematical model is mature.This is an effective new method to determine the optimal operating technical parameters of making up nano materials.更多还原
