Emisebeni ezishisayo

emisebeni Thermal (emisebeni) kuyinto ukudluliswa of energy ezishisayo olunikezwa amagagasi kagesi kusuka umzimba eyodwa kuya kwenye. It kuvela ngenxa amandla zomzimba zangaphakathi. Kulokhu ubude wave zokhahlamba kusuka micrometer 0.74 1000. Waves ukuthi abe obuphelele ezithile, kuthiwa amuncwa wumzimba bese idlule emkhathini. Into ezithakazelisayo wukuthi emisebeni singenzeka hhayi kuphela endaweni ethile, kodwa futhi benganelisekile. Le nqubo uphehla ukushisa - samandla.

emisebeni Thermal singenzeka ngenxa zamakhemikhali noma enuzi kusakazeka kagesi, kanye ngesenzo mechanical phezu into. Amandla lapho ikhishwe lungathunyelwa ngokuthintana, okusho ukuthi, ukuxhumana phakathi izinjongo amazinga aphakeme okushisa aphansi futhi ngokusebenzisa ezokuthutha zoketshezi noma amagesi noma ngemisebe (ukudluliswa ukushisa emthonjeni endabeni). Indlela yokugcina iyakhiqiza impela sikhiphe ukushisa. Heat imisebe baphathe amandla, futhi uma befika ngale ndaba, le energy amuncwa umzimba - futhi leti eshubile. Lapho izinto ezimbili okushisa ahlukene mbeni nomunye, yakheke ukushisa ukugeleza, okuyinto iyeke lapho izinga lokushisa lomzimba uqhathaniswa. Ngakho, kwenzeka emisebeni ukushisa. Le nqubo singenzeka kunoma imvelo, isib, emkhathini, futhi ngemishini, ezifana e ngesibani incandescent.

Kufanele kuqashelwe ukuthi zonke umzimba kudlala ukukhanya ungaphazanyiswa futhi ubamba ukukhanya kwezinye izidumbu. Esimweni lapho kukhona yakhoibrium ezishisayo, ngoba ekusakazeni ngamunye nto sasikhipha futhi ugxile emisebeni kuyoba okufanayo. Kulokhu, singakhuluma mayelana ukungabi khona ukushisa exchange izinqubo emkhatsini wetincenye teluhlaka. Lapho izinga lokushisa elilodwa isici kunolunye, ababekade ngeke akhipha energy ezishisayo ngokwezinga elikhulu ukwedlula ukuncela kusuka kwenye umzimba. Lapha ungakwazi ukukhuluma mayelana nokuba khona ukudluliswa ukushisa emkhatsini wetincenye teluhlaka.

Cabanga ukuthi emisebeni ukushisa kwayena nezici zakhe.

Kuyaziwa ukuthi amalunga sishisiswe lokushisa eliphezulu eyaziwa zikhanyiswe. Lesi simo esiyingqayizivele sibangelwa ubizwa emisebeni njengoba ezishisayo. It ufezwa ezihambayo molecule ketshezi kokuba lokushisa ngenhla zero. Ngakho, izinga lokushisa eliphezulu obusuka iDemo-wave abonakalayo nganoma ongaphakeme - infrared eside.

Cabanga ngesibonelo lesi simanga. Ngakho, indawo ezimweni eziningi ukufuthelana nge kagesi ukushisa emitters. Uma lokhu ekushayweni obomvu helices ezishisayo kanye emisebeni ebonakalayo. Futhi amaza okushisa ithwala ukushisa, okuyinto ukufuthelana kanye emagcekeni ejele.

Heat emisebeni - uhlobo emisebeni eyingozi kuba sezingeni lizama ukuzivumelanisa ukuthi hhayi ekushintsheni imingcele macroscopic. Zonke ezinye izinhlobo emisebeni non-zilingana.

Ingqikithi yayo yonke imisebe efanayo. It uvezwa uhlobo amagagasi kagesi lokusakaza emkhathini. kwakhiwa amandla Thermal is by odala amandla yangaphakathi timphawu eshubile. Isibalo lolu hlobo amandla incike lokushisa kanye izakhiwo ngokomzimba we umzimba, okuyinto lukhipha.

emisebeni Thermal udlala indima ebalulekile ezingokwemvelo nasezintweni ezenziwa abantu. Ilanga linamandla ukushisa kurediyetha. Amandla emisebeni ezishisayo cishe 1.3 W / m2.

Ngakho, ngo- yakhoibrium thermodynamic zonke izakhi ze-uhlelo babe izinga lokushisa elifanayo. Amandla of emisebeni ezishisayo lapho avela ngayinye yomzimba incephezeliswa amandla okuyinto amuncwa idatha umzimba. inqubo okunjalo kwezinkolo kubizwa ngokuthi i yakhoibrium ekushayweni ezishisayo.
