针对四色猜想，把图中任意一个区域周边与之紧邻区域的个数分为奇数或偶数情况；再把一个区域及其周边与之紧邻区域组成的图形分为鳞状域或围势域考虑，用数学归纳法证明了猜想成立。
針對四色猜想，把圖中任意一箇區域週邊與之緊鄰區域的箇數分為奇數或偶數情況；再把一箇區域及其週邊與之緊鄰區域組成的圖形分為鱗狀域或圍勢域攷慮，用數學歸納法證明瞭猜想成立。
침대사색시상，파도중임의일개구역주변여지긴린구역적개수분위기수혹우수정황；재파일개구역급기주변여지긴린구역조성적도형분위린상역혹위세역고필，용수학귀납법증명료시상성립。
Against to the four-color conjecture, in any area in vicinities thereto, the number of the immediate area can be divided into an odd or even case;then a region and its surrounding contrast to the immediate area consisting of graphics into squamous domain or confining potential domain considered, the simple mathematical induction to prove the conjecture is true.
