Lo mhlaba otsalayo yi iyunifom kunye non-uniform: abalinganiswa kunye nokuchongwa

Enye nezimaphambili ezingundoqo ezisetyenziswa physics, nguye lo mhlaba otsalayo. Esisebenza phezu ihamba izityholo zombane. Wenzeka kwaye ndaziva ngabantu, kodwa ubukho bayo bangonakala okufunyenweyo umazibuthe okanye intsimbi. Kwakhona zilula ngokwaneleyo ukuba baqonde indlela lo mhlaba otsalayo kuthiwa yohlobo olunye kunye owahlukeneyo.

Ukuchongwa ubhaqo iindlela lo mhlaba otsalayo

Xa sijongene ingqiqo mhlaba otsalayo, siye umbuzo malunga uhlobo lo mhlaba otsalayo, iyunifom okanye ezingezo-uniform ngayo. Ngaphambi kokuba siphendule lo mbuzo, kufuneka ukumisela imigaqo sokuqala.

Lo mhlaba otsalayo Kucingelwa ukuba siqwalasele uhlobo olulodwa lwezinto ezikhoyo kufutshane ihamba izityholo zombane, ingakumbi kufuphi izinikezeli yangoku-ethwele. Ungafumana ngokusebenzisa magnetic ngenaliti okanye zentsimbi imvuthuluka.

endle eyohlobo olulodwa

Kubonakele ngaphakathi umazibuthe strip kunye solenoid, xa ubude mkhulu kakhulu ubukhulu. Kulo mzekelo, ulawulo iikhonto nasesithupheni lo mhlaba otsalayo ziya ibhekiswe ebalwa.

imigca Magnetic ezi parallel kwaye tye, ukungabi phakathi kwabo usoloko umnye, amandla efuthe kumgaqo nosiba engaphenduli ayahlukanga konke konke iingongoma ubukhulu kwicala yayo.

endle inhomogeneous

Kwimeko kukho imigca inhomogeneous Imagnethi yomhlaba iya ungagotywa, lo therebetween void yahlukile kwi ubukhulu, amandla nefuthe nosiba kuyahlukahlukana kwiindawo ezahlukeneyo yobukhulu yayo entsimini kunye nolwalathiso. Kwakhona, amandla ebambeleyo phezu komcu obekwe kwi utolo entsimini umazibuthe, lisebenza amanqaku ezahlukeneyo kunye ezahlukeneyo umthamo kunye nolwalathiso yomkhosi. Oku kubizwa intsimi inhomogeneous. Imigca yasendle kujikwa ezinjalo, phinda iyahluka ukusuka kwindawo ukuba aveze.

Ukuze ukubona olu hlobo entsimini, mhlawumbi kufuphi umqhubi ngqo yangoku-ephethe, isiqwenga umazibuthe kunye solenoid.

Yintoni na le migca magnetic

Kwindawo yokuqala xa umsebenzi kufuneka limisele mhlaba otsalayo ukuba bomzi okanye inhomogeneous, ibunjiwe, kufuneka ukuchonga imigca zemagneti, imilo leyo kucaca ukuba iimpawu.

Obonisa lo mhlaba otsalayo baqalisa ukusebenzisa imigca ngemagnethi. Bona imicwe ecingelwayo ibekwe ecaleni inaliti Imagnethi yomhlaba kunye ibekwe entsimini ngemagnethi. Bamba umgca nosiba singavuselelwa nayiphi na indawo yasendle, kuya kuba ulwalathiso usoloko ekufutshane.

indlela

Phuma kwipali elingasentla nemagnethi zize zithunyelwe ngasemzantsi. Ngaphakathi umazibuthe yonke ngokungqongqo malungana. Le migca abanayo ekuqaleni okanye ekupheleni, ivalwa okanye ukusuka Infinity infinity.

Ngaphandle umazibuthe imigca zezona ezinabantu kufutshane zezibonda. Kulo kucaca ukuba kakhulu nefuthe intsimi kufuphi izibonda, kunye nomgama ukusuka ezantsi kuyo of buthathaka. Njengoko ukuba imicwe ngemagnethi ziya kujikwa, ulwalathiso kwemikhosi osebenza nosiba, nayo yatshintsha.

Indlela ukuba sisondele

Ukuze uqonde umahluko phakathi intsimi olufanayo kazibuthe owahlukeneyo, kufuneka ukufunda kukuveza usebenzisa imigca ngemagnethi.

Umzekelo uniform ukwenzeka Imagnethi yomhlaba kufuneka kuqwalaselwa ebizwa ngokuba yi-solenoid ogama ngasentla nto leyo ucingo coil zezindlu apho ngoku uvumelekile. Ngaphakathi kuyo, kukho mhlaba otsalayo kungathathwa bomzi, ukuba ubude mkhulu kakhulu sangqa (ohlobo intsimi ngaphandle uya kuba non-uniform, imigca ngemagnethi ziza kubekwa kwakunye umazibuthe band-lokuphumelela).

endle Uniform nayo ibekwe embindini zephetshana umazibuthe osisigxina. Kummandla abanqongopheleyo indawo kunokwenzeka ukuba bavelise kwaye intsimi efanayo zibuthe, apho amandla kwi utolo magnetized iya kulingana na umthamo kunye nolwalathiso.

Obonisa lo mhlaba otsalayo, esebenzisa mzekelo ulandelayo. Ukuba umgca iya kuba aa-moya bezoba yaye sikhokelwa le uzibonayo, bona ibonisa iminqamlezo, ukuba uzibonayo - amanqaku. Njengokuba le yangoku, umnqamlezo nganye ifana nomsila ebonakalayo besuka iintolo ukukhangela, yaye ingongoma - Iintolo zitsolile, nto leyo iyabhabha kuthi.

Imfuneko 'Zoba efanayo kunye imagnethi ezingezo-uniform "kulula doable. Vele wenze le migca kazibuthe endle banikwa iimpawu (yohlobo olunye kunye inhomogeneous).

Nangona kunjalo, ubukho amasimi non-uniform nzima kakhulu lo msebenzi. Kwimeko ngobuwena enjalo, ukulungiswa yoko emzimbeni ngokusebenzisa i equation jikelele engalindelekanga.

umahluko

Impendulo umbuzo malunga ngomahluko phakathi intsimi olufanayo kazibuthe owahlukeneyo, ngokulula ngokwaneleyo ukunika. Okokuqala konke oko kuxhomekeke kule migca zibuthe. Kwimeko lelizwe efanayo umgama phakathi kwabo kuya kubakho enye, yaye babekwa ngokulinganayo, kunye namandla efanayo esebenza phezu izixhobo nanini na. yonke ngokungqongqo ukuba amasimi non-uniform esahlukileyo. Line edyokhweni ibekwe kwiindawo ezahlukeneyo izinto ngamandla olungalinganiyo phezu izixhobo.

Ukuziqhelisa, ngokufuthi kwenzeka intsimi inhomogeneous, kwakunye khumbula, kuba amasimi yohlobo olunye lunokwenzeka ngaphandle ngaphakathi into, efana umazibuthe okanye solenoid. esweni zangaphandle uya kurekhodwe ukungafani kobuhlanga.

ifildi bangabonwa

Eqonda ukuba iyunifom kunye non-uniform Imagnethi yomhlaba, kunye nokumisela zezikhali zabo kufanele azi ngayiphi indlela bangabhaqa nabo.

Eyona elula kuba ngokuqinisekileyo le experiment olwenziwa Oersted. It sikuko ngokusetyenziswa nosiba, nto leyo inceda ukufumanisa ubukho umsinga wombane. Xa lwangoku ahambe kumqhubi ibekwe kufuphi utolo ukuhambisa, ngenxa yokuba kukho amasimi yohlobo olunye kunye inhomogeneous ngemagnethi.

Ukusebenzisana ngababhexeshi zangoku

Nganye umqhubi yangoku-Ukuthwala waphawula nemagnethi, ukwenza amandla athile elandelayo. Kuxhomekeka kwicala lwangoku, izinikezeli Kuza kutsalwa umdla okanye bakucaphukele ukusuka kwenye. Amasimi evela kwimithombo eyahlukeneyo kwaye iya elisongiweyo ukwenza intsimi ngenxa eyodwa.

Njani kwaye yintoni

Imizekelo endle yohlobo olunye kunye inhomogeneous sibubona isicelo kwi cathode ray tube, ngaba abukhali lidlule lwangoku. Ukuze ufumane imilo ezinqwenelekayo lo mhlaba otsalayo isicelo lugs kweeshelfu namakhaka nemagnethi eyenziwe amalaphu ukuba permeability eyomeleleyo ngemagnethi.

Isiphumo kwamabala inhomogeneous ngemagnethi ekwaziyo ekutshintsheni indlela nesenzeko lakho engokoqobo nemichiza, ubukhulu becala inkqubo owahlukeneyo. Imbonakalo kwe- lesiphithiphithi kukhokelela ekwandeni-odolo eziliqela ubukhulu isantya ukuhanjiswa kwegesi ukusuka kulwelo ukuya kumphezulu ngohlobo microbubbles. Umphumo emzimbeni kwaye kwaku- local amasuntswana microcrystallization ngenxa inkqubo komelezwa. In high amandla flow eendaba indlela esikwaziyo ukuvelisa radicals ezamahala, ioksijini singlet, pheroksayidi kunye initrogen. Kwenzeka coagulation, kunye neemveliso ulwelo zibangelwa yi umonakalo ukhukhuliseko.

Ngexesha cavitation ixabiso ngenxa amaqamza hydrodynamic enkulu kunye nemingxuma nzima entrainment yabo ulwelo kwiindawo xi eliphantsi kwindawo xi eziphezulu apho amaqamza ukuwa kwenziwa. Ngexesha ngokuwa inani elincinane kwiqamza iye umxholo umoya ephantsi kwaye kukho imichiza yokusabela eyomeleleyo ezifanayo kwalawo plasma. Ubukho kwamabala non-uniform ngemagnethi kukhokelela ukuqanda ukungazinzi, wokuqhekeka kobudlelwane phakathi kwabo kunye ukuvela imisinga asakhasayo kunye maqampu. Sisazi ukuba uxinzelelo kwi embindini omtsha uvikivwa, ukuba ukuguquka egesi ubukhulu encinane.

Ngexesha imilinganiselo yoqheliso entsimini ngemagnethi nonuniform kufuneka kukhunjulwe ukuba ombane iHolo yi ngokomlinganiselo ubukhulu amandla yasendle avareji kummandla lingqongwe kumphezulu transducer.

Ukuze kukugxininisa imiqadi paraxial nazo kusetyenziswa ifildi non-uniform ngemagnethi lisekwa jiko amafutshane imibhijelo multilayer, ubude apho yendebe kunye ubukhulu bayo. An electron falling in a mhlaba, imikhosi, ukutshintsha indlela yayo. Electronic baphenjelelwe imikhosi ezinjalo besondela axis lens, ne-moya apho iye indlela bayo egosogoso. Electron ehamba ukwehla icandelo leyo inqumla axis lens kwindawo elinikiweyo.

ukwanda factor Spatial ibangelwa amasimi inhomogeneous rassredotachivaniem komhlaba kwi kummandla kwenkqubo owahlukeneyo, eclipsing ulwelo. Ukuze ufumane inani amanqanaba inversion indlela yokuzahlula isicelo entsimini inhomogeneous wadala umazibuthe multiband. imilo pole kuyafana kweentonga kwi quadrupole capacitor oscillator molekyuli usebenzisa ammonia.

Indlela yokusebenzisa

Magnetic ukushiyeka indlela efumanise ukuba kulandelelwano ngokusekelwe amandla imoto ye amasuntswana otsalayo amasimi non-uniform ukuba kuvela yomonakalo. Ngu ukuqokelelana powder enjalo ukuqinisekisa ubukho yomonakalo, ubungakanani kunye nendawo ababekwa kuyo kuluhlu izinto zaskenwa.

Ububi enkulu indlela ngemiqadi ngemolekyula kunye mhlaba otsalayo ngamandla inhomogeneous kugqalwa cleavage sisiphumo esincinane. Kukho indlela elula ebonakala abhalwa yokwandisa isiphumo. It iqulathe kwisicelo yoVandlakanyo otsalayo ukukhanya entsimini. Imibutho yabasebenzi iza kwenza kube lula ukuba andise ukusetyenziswa magnetometers precession senyukliya ngakwicala amasimi non-iyunifomu ngemagnethi.

Abaxhamla kule ndlela amandla ukusombulula phezulu, eyenza kube lula ukulungisa lo mhlaba otsalayo inhomogeneous siwenze kunye nexabiso magnetic tape yamasuntswana umaleko, kwaye kungenzeka lokufumana umonakalo kwi imiphezulu ezintsonkothileyo uvale Ekungeneni.

Bobubi abo imfuneko yolwazi processing zasesekondari abhalwe kuphela amasuntswana of zemagneti ecaleni bhanti, yobumbaxa yaye alondoloze tape demagnetization kwaye kuyimfuneko ukuthintela impembelelo kwamabala lwangaphandle ngemagnethi.

Lo mhlaba otsalayo yi iyunifom kunye non-uniform baxomoloza eqhelekileyo, nangona into yokuba abemi engabonakaliyo ezilula. Imizekelo Imagnethi yomhlaba yohlobo olunye kunye inhomogeneous sivakala iimagnethi bandpass kunye solenoids. Kulo mzekelo, ingabonwa ngokusebenzisa ngenaliti okanye intsimbi, imvuthuluka elula ngemagnethi.
