Waa maxay "kala duwan oo aalladda sare" waa maxay qoraalka ah ee microwave ka?

Deciphering microwave ka - waa "inta jeer aalladda sare." Dad badan oo u maleynayaa in tani ay tahay wax adag duurka abstruse of physics iyo xisaabta, iyo in ay iyaga ma khuseeyaan. Si kastaba ha ahaatee, xaaladda waa arrin oo kala duwan. qalabka microwave ayaa muddo dheer ku istiwooday nolosheena, oo iyaga waa la heli karaa meel kasta. Laakiin waa maxay?

kala duwan ee mawjadaha microwave

Sharaxaada microwave - shucaaca electromagnetic inta jeer aalladda sare, oo waxaa lagu abaabulaa spectrum inta jeer ee u dhexeeya UHF infrared iyo fog-duurka jooga. Wavelengths ee kala duwan waxaa laga soddon sintimitir in mid ka mid millimeter. Taasi waa sababta microwave waxaa mararka qaarkood loo yaqaan centimitir oo decimeter ku wavelengths. In suugaanta qoraalka microwave farsamo qalaad - duwan microwave. Waxaa la fahamsan yahay in Milanello waa mid aad u yar oo hirarka warbaahinta raadiyaha, kuwaas oo amarka ka mid ah dhawr boqol oo mitir marka la barbar dhigo.

guryaha microwave

Dhinacyada oo dhererkeedu, this hirarka nooca - dhexe u dhexeeya calaamadaha shucaaca radio iftiin, oo sidaas daraaddeed waxay leedahay guryaha labada noocyada. Tusaale ahaan, sida nuurka oo kale, hirarka kuwaas oo dacaayad jidka toosan iyo si xooga oo dhan daboolaa shay adag oo dheeraad ah ama ka yar. Sidoo kale in iftiinka shucaaca, microwave diiradda u saari karin, ka muuqataa, faafin qaab rays. Inkastoo microwave kelmadaha ay diiradda saartaa "super" kala duwan -high, anteenooyinkooda badan iyo qalabka raadaarka waa version yar weyn ee muraayadaha, lenses iyo xubno kale oo indhaha.

Qarni

Tan iyo shucaaca ee microwaves la mid tahay hirarka raadiyaha, oo waxaa la ahbaa hababka la mid ah. Deciphering microwave ku lug leedahay isticmaalka hirarka raadiyaha si ay iyada aragtida classical, laakiin ay sabab u tahay kala duwan ee soo kordha waa suurtagal ah in la kordhiyo tayada ee ay la isticmaalo. Tusaale ahaan, mid ka mid dogob kaliya karo "qaado" midig ilaa kun sheekaysi taleefan oo isku mar. Egyihiin microwaves iyo Nuur, ayaa muujiyay in cufnaanta sare macluumaad la qaadi karo cadaato waxtar leh ee technology radar.

Codsiga microwaves in radar

Hirarka in centimitir oo decimeter ee safafka ayaa la kulma oo xiiso wakhtigii dagaalkii labaad ee adduunka. Inkasta oo ay jiraan waxa loo baahan yahay hab wax ku ool ah oo cusub oo la ogaado. Haddaba, waxaan baaritaan microwave ah si ay u isticmaalaan in radar. line hoose waa in aad u daran, digir gaaban waxaa lagu bilaabay meel, ka dibna qaar ka mid ah rays, kuwaas oo laga diiwaan geliyay ka dib markii uu ka soo walxaha fog oo aan la garaneyn soo laabtay.

Isticmaalka microwaves ee isgaarsiinta

Sida aan ku sheegay, deciphering UHF - hirka sare aalladda. Injineerada iyo farsamo go'aansaday in ay isticmaalaan hirarka raadiyaha kuwaas oo sabab. In dalalka oo dhan si firfircoon u isticmaalaan khadka isgaarsiinta ganacsi ku salaysan gudbinta guutooyin-ruxruxo sare. calaamadaha noocan oo kale ah ma aha at qalooca dusha dhulka iyo xariiq toosan dhex saldhigyada isgaarsiinta Relay ku yaal dura meelaha dhaadheer oo ku saabsan konton kiilomitir.

Uma baahnid xaddi badan oo koronto ah, waayo, gudbinta, tan iyo microwaves ogolaan dhaweynta si ciriiri ah diirada iyo gudbinta, iyo sidoo kale saldhigyada Sammeecado electronic wanaajiyey ka hor ay sidayaan. Nidaamka of anteenooyinkooda, munaarado, laliska iyo qaateyaasha u muuqdaan kuwo qaali ah, laakiin waxaa bixinaya off awoodda macluumaad ah sida channels.

Nidaamka of munaarado radio in ay ku tiirsanaayeen calaamadaha microwave ka badan masaafo dheer jiri karo oo keliya dhulka. Waayo, wada xaajoodka Intercontinental isticmaalaya satalayt macmal ah, oo ku yaal kastana falagiisuu dhex geostationary dhulka oo uu ku sameeyo hawlaha repeater. satellite kasta waxay bixisaa dhowr kun oo khadaka warisgaarsiinta ee tayo sare leh si ay macaamiisha ay u gudbinta telefishanka iyo telefoonka calaamadaha isku mar.

waxyaabaha daaweynta Heat

The isku dayga ugu horeeya si ay u isticmaalaan mawjadaha microwave cuntada- helay dib u eegista wanaagsan, iyo xataa xamaasad leh. Microwave foornada maanta waxaa loo isticmaalaa sida guri, iyo warshadaha cuntada oo waaweyn. Ee ay laambadihii-awood sare, tamarta elektarooniga ah waa mid isku urursan ee mugga yar, kaas oo u ogolaanaya sheyga thermally loola dhaqmo waa daahir, is haysta iyo aamuseen.

Dhisay-in microwave waa kan ugu caansan ee reerka, iyo waxaa laga heli karaa in jikooyinka badan. Sidoo kale qalabka Ujeedada bulshada sida loo isticmaalo meel kasta oo kululaynta deg deg ah iyo diyaarinta cuntada. microwave la solay, tusaale ahaan, gabi ahaanba waa lagama maarmaan u ah element ixtiraamka makhaayad kasta.

Ilaha ugu waaweyn ee shucaaca

Horumarka isticmaalka microwaves waxaa la xidhiidha qalabka kale ee elektaroonigga ah sida magnetron klystron ah iyo in ay abuuri karaan tiro aad u badan oo ah tamar hirka sare. Isticmaal of magnetron ku salaysan mabda'a saabka resonant, oo derbiga waa inductance ah, iyo bannaan oo u dhaxeeya derbiyada - capacitance circuit resonant. The dhinacyada element this waxaa la soo xulay oo ku saabsan inta jeer ee ku haboon resonant microwave, kaas oo u dhigma lahaa in ratio la doonayo dhexeeya capacitance iyo inductance.

Sayidka, kelmadaha ee microwave ka - inta jeer ee aad u sarayso. Cabbirka matoor si toos ah saamayn ku xoogga shucaaca sida. Magnetrons yar mawjadaha sare ayaa aad u yaryar in xooggoodii ma gaadhi karto heer lagu qanci karo. Dhibaatadu waxa ay sidoo kale xusid mudan isticmaalaya magnet-culus. klystron waxaa qayb ahaan xalin, sida in this qalab kale oo elektaroonik ah uma baahna beerta dibadda.
