It is set that, the coordinate of the point Pi is (Ti,Vi), that of 1-1th is (Ti-1, Vi-1), the distance from Po to 1-1st is Rdi-1, the distance between P1-1 and Pi is Di, that to 1 is Rdi and among points between pan Pn, an optional point Pi is chosen and the actual distance from Po to Pi is found. In case a number of sampling of 1 is an even number, it becomes Pi=Pj, if that is an odd number, it takes the position before the point Pj. Assuming that the coordinate of point Pi is(Tj,Vj), the smooth distance from Po to Jth point is Sdi, a distance from Pi to Pj is Oj, the smooth distance to I is SDI is found. If it is as large as S=1, B type detergent, it is medium as 0.8 < S < 0.95, A type, if it is as small as S<0.8, c type detergents are chosen.
