	                	In this paper, the author deduced the Gradation Rule of the Conjugated Homo- logs E=a+b/N from the Linear Rule of the Homolo us Energy Factor E=a+b((2k-1)/k)sin(kπ/(2N+1)) and acquired a new Homolo us Function E=a+b(2k-1)/(N+1/2), which is better than Gradation Rule of the Conjugated Homologs. Five formulas of Linear Rule resently reported were tested and compared by using 96 series of data of photo-electron spectroscopy and 159 series of data of electren spectroscopy. The author holds that the Linear Rule of the Homol us Energy Factor is better.
