I-Carbon dioxide iyigesi engenambala nengenaphunga.Ingenye yezingxenye ezibaluleke kakhulu zomkhathi.Njenge-reactant eyinhloko ye-photosynthesis, ukugxila kwe-CARBON dioxide kuhlobene ngokuqondile nokusebenza kahle kwe-photosynthetic yezitshalo, futhi kunquma ukukhula nokuthuthuka, isigaba sokuvuthwa, ukumelana nokucindezeleka, ikhwalithi kanye nesivuno sezitshalo.Kodwa okuningi kakhulu ngeke kukhiqize umphumela we-greenhouse kanye neminye imiphumela, kodwa futhi kulimaza impilo yabantu.Kumaphesenti angu-0.3, abantu babhekana nekhanda elibonakalayo, futhi kumaphesenti angu-4-5 bazizwa benesiyezi.Indawo yasendlini, ikakhulukazi emakamelweni ane-air-conditioning, ivalwe ngokuqhathaniswa.Uma kungekho umoya isikhathi eside, ukuhlushwa kwe-carbon dioxide kuzokhula kancane kancane, okuyingozi empilweni yomuntu.Ngokwezinga lekhwalithi yomoya wasendlini elaqalwa ngo-2003, inani elijwayelekile lengxenye yevolumu yesilinganiso sansuku zonke sokuqukethwe kwekhabhoni dioxide akufanele lidlule u-0.1%.
Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, ukuthuthuka okukhulayo kwezinga lokuphila kwabantu kanye nokunaka kwabantu okwandayo ekuvikelweni kwemvelo, ukuqapha okulinganiselwe kanye nokulawulwa kwegesi ye-carbon dioxide sekuyisidingo esikhulayo se-air conditioning, ezolimo, ukwelashwa, izimoto kanye nokuvikelwa kwemvelo. .Izinzwa ze-Carbon dioxide zisetshenziswa kabanzi embonini, ezolimo, ezokuvikela kazwelonke, ezokwelapha nempilo, ukuvikelwa kwemvelo, i-aerospace kanye neminye imikhakha.
Isimiso sokusebenza senzwa ye-carbon dioxide yethulwa ngezansi.
Yonke into inomkhakha wayo womugqa ogqamile, kanye ne-spectra yokumuncwa okuhambisanayo, njengama-molecule e-carbon dioxide gas.Ukudlidliza kwe-lattice kwezinto ze-ceramic kanye nokunyakaza kwe-electron kunomphumela wesithiyo, izinga lokushisa liyakhuphuka, ukudlidliza kwe-lattice kuyaqiniswa, i-amplitude iyanda, isenzo se-electron esivimbelayo siyaqiniswa.Ngokuvumelana nethiyori yokumuncwa ekhetha igesi, lapho ubude beza beza bomthombo wokukhanya buqondana nobude begagasi bokumuncwa begesi, ukumuncwa kwe-resonance kuzokwenzeka, futhi amandla awo okumunca ahlobene nokugxiliswa kwegesi.Ukugxila kwegesi kungalinganiswa ngokulinganisa ukushuba kokukhanya.
Njengamanje, kunezinhlobo eziningi zezinzwa ze-carbon dioxide, okuhlanganisa uhlobo lwe-thermal conductivity, uhlobo lwe-densitometer, uhlobo lokumuncwa kwemisebe, uhlobo lwe-conductivity kagesi, uhlobo lokumuncwa kwamakhemikhali, uhlobo lwe-electrochemical, uhlobo lwe-chromatography, uhlobo lwe-mass spectrum, uhlobo lwe-infrared optical njalonjalo.
Ukumuncwa kwe-infrared carbon dioxide gas sensor kusekelwe esimisweni sokuthi i-spectrum yokumunca igesi iyahlukahluka ngezinto ezahlukene.Inzwa yeCarbon dioxide ngokulawulwa kwesekethe yomshayeli welambu le-infrared ngaphakathi kwebhande le-infrared elimisiwe, ukumuncwa kwegesi ngaphansi kokuhlolwa, ukuguqulwa kwe-infrared light amplitude, futhi ngokubalwa kwesheke sokushintsha kokuhlushwa kwegesi, isignali yokuphuma kwenzwa ngemva kokuhlunga, ukucubungula okuthuthukisiwe kanye Iqoqo le-ADC nokuguqulwa, okokufaka ku-microprocessor, isistimu ye-microprocessor ngokusho okuqoqiwe kunxephezela izinga lokushisa elihambisanayo, ingcindezi, izinga lokushisa, ingcindezi, ekugcineni kubalwe ukuphuma kwe-carbon dioxide density kudivayisi yokubonisa ngaphansi kokuhlolwa.Ihlanganisa ikakhulukazi i-spectroscopy ye-diode laser absorption, i-photoacoustic spectroscopy, i-spectroscopy yokuthuthukisa umgodi kanye ne-non-spectral infrared spectroscopy.Inzwa yokumuncwa kwe-infrared inezinzuzo eziningi, ukuzwela okuphezulu, isivinini sokuhlaziya okusheshayo, ukuzinza okuhle, njll.
Inzwa yegesi ye-electrochemical CARBON dioxide iyinzwa yamakhemikhali eguqula ukugxiliswa (noma ukucindezela ingxenye) ye-carbon dioxide ibe isignali kagesi ngokusabela kwe-electrochemical.Ngokusho kokutholwa kwamasiginali kagesi, uhlobo lwe-electrochemical luhlukaniswe ngohlobo olungase lube khona, uhlobo lwamanje kanye nohlobo lwe-capacitance.Ngokwesimo se-electrolyte, kukhona ama-electrolyte anguketshezi nama-electrolyte aqinile.Kusukela ngawo-1970, izinzwa eziqinile ze-electrolyte CARBON dioxide ziye zakhathazeka kakhulu ngabacwaningi.Umgomo wenzwa eqinile ye-electrolyte I-CARBON dioxide inzwa ukuthi into ezwela igesi ikhiqiza ama-ion lapho idlula kugesi, ngaleyo ndlela yakhe amandla e-electromotive futhi ilinganise amandla e-electromotive ukuze kulinganiswe ingxenye yevolumu yegesi.
Ukusebenzisa i-thermal conductivity ehlukene ye-CARBON dioxide namanye amagesi inzwa yegesi ye-carbon dioxide nakho kusetshenziselwa okokuqala ukuthola inzwa ye-carbon dioxide.Kodwa ukuzwela kwayo kuphansi.
Inzwa yegesi ye-surface acoustic wave (saw) kukristalu we-piezoelectric embozwe ungqimba lokukhangisa okukhethiwe kwefilimu yegesi ezwelayo, lapho amafilimu azwela igesi ehlangana negesi ngaphansi kokuhlolwa, enza ikhwalithi yefilimu ezwelayo yegesi, uhlamvu olufana ne-viscoelasticity kanye ukushintsha kwe-conductivity, kubangela imvamisa yegagasi elingaphezulu le-acoustic yekristalu ye-piezoelectric ukuthi ikhukhuleke, ukuze ibone ukugcwala kwegesi.Inzwa yegesi ye-surface acoustic wave (SAW) iwuhlobo lwenzwa enkulu ezwelayo.Ngaphezu kwalokho, inzwa yegesi ye-quartz crystal microbalance gas isebenza ngesimiso esifanayo nenzwa ye-SAW, ngakho-ke nayo ingeyenzwa enkulu ebucayi.Inzwa ye-mass sensitive ngokwayo ayinakho ukukhetha kugesi noma umhwamuko, futhi ukukhetha kwayo njengenzwa yamakhemikhali kuncike kuphela kuzakhiwo zezinto zokumboza phezulu.
I-semiconductor carbon dioxide gas sensor ISEBENZISA inzwa yegesi ye-semiconductor njengenzwa yegesi, futhi inzwa ye-metal oxide semiconductor carbon dioxide gas inezici zokusabela okusheshayo, ukumelana okuqinile kwemvelo kanye nesakhiwo esizinzile.
