【摘要】:14912:2003definesthefollowingquantitiescommonlyusedtoexpressthecompositionofgasmixtures:molefraction,massfractionandvolumefraction,aswellasmoleconcentration,massconcentrationandvolumeconcentration.Relatingtothesequantitiesofcomposition,ISO14912:2003providesmethodsfortheconversionbetweendifferentquantitiesandtheconversionbetweendifferentstateconditions.Conversionbetweendifferentquantitiesmeanscalculatingthenumericalvalueofananalytecontentintermsofoneofthequantitieslistedabovefromthenumericalvalueofthesameanalytecontent,atthesamepressureandtemperatureofthegasmixture,givenintermsofanotherofthesequantities.Conversionbetweendifferentstateconditionsmeanscalculatingthenumericalvalueofananalytecontent,intermsofoneofthequantitieslistedabove,underonesetofstateconditionsfromthenumericalvalueofthesamequantityunderanothersetofstateconditions,i.e.pressureandtemperature,ofthegasmixture.Gasmixturecompositioncanbeconvertedsimultaneouslybetweendifferentquantitiesofcompositionanddifferentstateconditionsbycombinationofthetwotypesofconversion.ISO14912:2003isonlyapplicabletohomogeneousandstablegasmixtures.Thereforeanystateconditions(pressureandtemperature)consideredneedtobewelloutsidefromthecondensationregionofthegasmixtureandthatofeachofthespecifiedanalytes.
