From the measurment at 3518 cm~(-1) in carbon tetrachloride,the reciprocal of molecular weight M_n determined by IR instead of VPO(Vapour Pressure Osmometry) is proportonal to absorbance E of terminal hydroxy in the polymer. The relation is:1/M_n=1.15×10~(-4)+1.53×10~(-3)E.
The condition of landolt reaction in the H_2O_2-Cl~(-)-primaquin-IO_4~- system and liner relation for 1-6μg·ml~(-1) of IO_4~- and reciprocal of induction period have been investigated And calculated reaction mechanism.
The elastic leaf spring guide is simple in structure and there is no error of principle,and error of geometric parameter in the guides is systematic error,which is compensated. Meanwhile,movements of the table in directions are independent according to designing principle,which avoids reciprocal coupling.
1. For problems existing in AHP, new parameter prioritization methods (PPM1) and (PPM2) for priority vectors of fuzzy consistent and positive reciprocal judgment matrices are proposed based on the consistency of human thinking.
