过程层析成像技术的发展及应用

综述与评论,2009,36(1):1~5ControlandInstrumentsinChemicalIndustry马平,周晓宁,田沛(,071003):阐述过程层析成像技术的研究背景及研究意义,就国内外研究动态及该技术的发展做了详细的论述介绍和分析了不同的过程层析成像技术,并得出超声波流动层析成像系统和电容流动层析成像系统将是未来流动成像技术发展的两大主流,多机理多模态层析成像技术将是过程层析成像技术的发展趋势:过程层析成像;超声波流动层析成像;电容流动层析成像;多机理;多模态:TK313:A:10003932(2009)0100010511.1,,(twophaseflowtwocomponentflow)(multiphasemulticomponentflow)/,////,,,,[1]*1.2,,,;,,,,,,,,,,,(ProcessTomography,PT),[2,3]:(1),(2),,(3),PT2080,CT,,PT,[4,5]PT,,,PT,PT,22.1,*:20090108():(50736002E0606);863!(2007AA05Z331)2050,1972HounsfieldX,,(ComputerizedTomography,CT)/CT!,,X,,,,2080,(UMIST)BeckPlaskowski,19888/,1990,12,(Transputer),,40/(MorgantownEnergyTechnologyCenter)1990152.4mm,416,430/,100/[6]1988,UMIST,KarlsruheMesch/[7]1999,199608TechnicalForesightChallenge(UMIST,UniversityofLeeds,UniversityofExeter)(TheVirtualCenterforIndustrialProcessTomography)!20050905~08Aizu,20070903~09Bergen[4,8]2.2PT,2080,[9],198620028,199520044,,ECTECT,,[6,10],;,,ECT,,BPART,,,,,ECT,,,,,,,33.1∀2∀36PT,radon:,;,;,(,,);,,,,(1)1PT3.2PT,1972HounsfieldCT,CT,(X)()PT[11]3.2.1(OpticalTomography),,,,,[12],,;,!(SoftField),,3.2.2(ElectromagneticTomography,EMT)2090,,,EMT:()EMT[13]3.2.3(ElectriChargeTomography):,,,,,,3.2.4(ElectricalResistanceTomography,ERT):,,,,ERTBarberBrown,,,,,,ERT,,2080,ERT,;;;[14]2080ERT,,ERT;ERT,ERT;;[15]∀3∀1.3.2.5(ElectricalCapacitanceTomography,ECT):,,,,,,,22ECT,,:(1)(2)!,(3),()3.2.6(UltrasoundComputerizedTomography,UCT):,,,3[16]3,,,,,,[16,17]:(1),,,;,,(2),,,,//,,(3),4,,,:(1),,(2),(3),(4),(5),,,,,∀4∀36,,,,,LeddsECTERT,,ECT/ERT!,,,,,5,,,,:[1].[J].,2000,21(1):4-7.[2],.[C]//.:,1988,(17):9-26.[3],,,.[J].,2004,25(4):1035-1036.[4].[D].:,1995.[5].[M].:,1991.[6],.[C]//2.[7],.[C]//:.1995:63-72.[8],.[C]//.:,1992:191-192.[9],,,.[J].,2001,22,(5):645-648.[10].[D].:,2005.[11]HANSONKM,WECKSUNGGM.LocalBASISfunctionbasisFunctionApproachtoComputedTomography[J].AppliedOptics,1985,24:4028-4039.[12]ALBAF,CRAWLEYGM,HIGGSDMJ.AcousticAttenuationSpectroscopyParticleSizingofHighConcentrationDispersions[J].WorldCongressonParticleTechnology,1998,(3):287-296.[13],,,.[J].,2005,(4):42-46.[14],,,.[J].,2001,22(2):195-198.[15],,.[J].,2004,31(2):52-54.[16]XULiJun,XULingan.UltrasoundTomographySystemUsedforMonitoringBubblyGas/LiquidTwophaseFlow[J].IEEETransactionsonUltrasonics,Ferroelectrics,andFrequencyContro,l1997,44(1):67-76.[17]ALLEGRAJR,HAWLEYSA.AttenuationofSoundinSuspensionsandEmulsions:TheoryandExperiments[J].JAeoustSoeAm,1972,(51):1545-1564.DevelopmentandApplicationofProcessTomographyMAPing,ZHOUXiaoning,TIANPei(ControlScienceandEngineeringCollege,NorthChinaElectricPowerUniversity,Baoding071003,China)Abstract:Theresearchbackgroundandsignificanceofprocesstomography(PT)technologywereintroduced.TheresearchtrendsanddevelopmentofPTtechnologyindomesticandforeignwerediscussed.ThedifferentPTtechnologieswereanalyzed.Theconclusionwhichultrasoundcomputerizedtomography(UCT)systemandelectricalcapacitancetomography(ECT)systemwillbethetwomainstreamsofPTtechnologydevelopmentinfutureisreached.PointoutthatmultimechanismandmultimodalwillbethedevelopmenttrendsofPTtechnology.Keywords:PT;UCT;ECT;multimechanism;multimodal欢迎来稿欢迎订阅欢迎刊登广告∀5∀1.
