Strict Method and Its Application of Fractional Addition Experimental Design

The fractional addition experimental method is used to solve some experimental problems on different level. It is an optimum seeking method of the orthogonal and nonorthogonal design intersection. In this paper, strict method is given to analysis of data and variance of fractional addition experimental design, that is, the deviation square sums, its degress of freedom, revised coefficient and etc are derived and explained with mathematical relationship. At the same time, fractional additional and quasi\|level method are combined flexibly to give full play to respective merits, so that the experimental times are reduced and it is convenient to calculate and analyse.
