Research Abstract |
IT IS VERY IMPORTANT FOR USAGE OF FALLING WATER TO ESTMATE TOTAL IONIC CONCENTRATION IN THE WATER WITH HIGHER ACCURACY AND ALSO TO GET INFORMATIONS ABOUT A DYNAMIC STRUCTURE OF WATER MOLECULES. THEREFORE,THE NEXT THREE THEMES WERE MAINLY RESEARCHED. (1) DETERMINATION OF A COMMON ELECTRIC CONDUCTIVITY FOR FALLING WATER APPLICABLE IN NATION-WIDE. (2) ESTABLISHMENT OF ESTIMATION METHOD OF TOTAL IONIC CONCENTRATION IN THE WATER USING THE COMMON ELECTRIC CONDUCTIVITY SIMPLY AND ACCURATELY. (3) ESTABLISHMENT OF MEASUREMENT OF DYNAMIC STRUCTURE OF WATER MOLECULES BY ^<17>O-NMR SUPERCONDUCTED. RESULTANTLY,THE WORK GIVES US THE CONCLUSIONS AS FOLLOWS. (1) THE COMMON ELECTRIC CONDUCTIVITY APPLICABLE FOR A FALLING WATER,IRRESPECTIVE OF RAIN OR SNOW,NATION-WIDE IS 11.470*10^<-4>[1/OMEGA・cm] (2) BY USING IT,IT IS POSSIBLE TO ESTIMATE TOTAL IONIC CONCENTRATION IN THE WATER WITH THE ACCURACY OF <plus-minus>6% FOR ITS ELECTRIC CONDUCTIVITY MEASURE (3) AN APPLICATION OF POLYNOMINAL SIMILARITY FOR EVALUATION OF A HALF-WIDTH MEASURED BY ^<17>O-NMR HAS GREAT POSSIBILITY FOR AFFORDING AN EFFECTIVE MEAN OF EVALUATING CHEMICAL OR BIOCHEMICAL ACTIVITY OF WATER AND CONTROLLING A CLUSTER SIZE OF WATER MOLECULES.
