Ukusetshenziswa Kwamagagasi E-Electromagnetic: Inguquko Yezobuchwepheshe Emikhakheni Ehlukahlukene
Amagagasi kagesi ayizinto zemvelo ezihilela ukushintsha amasimu kagesi namagnetic aqonde komunye nomunye futhi asakazeke emkhathini ngaphandle kwesidingo sendlela. Ubuchwepheshe obuningi esibusebenzisayo ekuphileni kwethu kwansuku zonke busebenzisa izakhiwo ezihlukile zala magagasi. Leli phepha lizoxoxa ngokusetshenziswa okuhlukahlukene kwamagagasi kagesi kwezokuxhumana, kwezokwelapha, embonini, kwezobuchwepheshe bolwazi, kanye nasemvelweni.
Ukuxhumana Nokusakaza
Enye yezindlela ezivame kakhulu zokusebenzisa amaza kagesi kubuchwepheshe bezokuxhumana. Amaza omsakazo, okuhlanganisa i-AM ne-FM, kanye nama-microwave, asetshenziselwa ukudlulisa umsindo, izithombe, kanye nedatha ngaphandle kwentambo emoyeni. Kulesi simo, sijwayelene nobuchwepheshe obufana nomsakazo, ithelevishini, omakhalekhukhwini, kanye ne-Wi-Fi.
Umsakazo kanye nethelevishini kusebenza ngokudlulisa nokwamukela amaza kagesi ngezikhathi ezithile. Umsakazo we-AM (Amplitude Modulated) kanye ne-FM (Frequency Modulated) ziyahlukahluka endleleni ezifaka ngayo ulwazi kugagasi lomthwali. Ngakolunye uhlangothi, ithelevishini isebenzisa amaza e-analog noma edijithali ukuze ikhiphe umsindo nezithombe ezithathwe yi-TV receiver.
Amaselula namanethiwekhi e-Wi-Fi asebenzisa ubuchwepheshe be-microwave ukuthumela nokwamukela idatha. Lobu buchwepheshe buvumela ukuxhumana okusheshayo ngezwi, umbhalo, kanye nevidiyo emhlabeni jikelele. Intuthuko kwezobuchwepheshe be-microwave ikhulise amakhono ala madivayisi ngokwejubane kanye nomthamo wedatha.
Ezokwelapha Nezempilo
Emkhakheni wezokwelapha, amaza kagesi asetshenziselwa ukuxilongwa nokwelashwa. Enye yezindlela ezaziwa kakhulu zokusebenzisa ama-X-rays ukuze kuthathwe isithombe sangaphakathi lomzimba womuntu. Ama-X-rays ayindlela yokukhanya kagesi okunamaza amafushane kakhulu angangena ezicutshini zomzimba futhi adale izithombe zamathambo nezitho zangaphakathi.
I-Magnetic Resonance Imaging (MRI) ingenye ubuchwepheshe obusebenzisa amasimu kazibuthe namagagasi omsakazo ukukhiqiza izithombe ezinemininingwane yezitho nezicubu emzimbeni. Inzuzo ye-MRI ngaphezu kwezinye izindlela ukuthi ayisebenzisi imisebe ye-ionizing, okwenza ibhekwe njengephephile ezigulini.
Ngaphezu kwalokho, ukwelashwa ngemisebe kusebenzisa imisebe ye-gamma noma imisebe ye-X enamandla aphezulu ukubulala amangqamuzana omdlavuza noma ukunciphisa izimila. Ubuchwepheshe be-laser, olunye uhlobo lwemisebe ye-electromagnetic, busetshenziswa nasezinqubweni ezahlukene zezokwelapha, okuhlanganisa ukulungiswa kombono (i-LASIK), ukwelashwa kwesikhumba, kanye nokuhlinzwa.
Imboni Nokukhiqiza
Amagagasi kagesi adlala indima ebalulekile embonini nasekukhiqizeni. Enye indlela yokusebenzisa isekucubunguleni izinto, njengokushisela kanye nokusika insimbi nge-laser. Ukusika nge-laser kunikeza ukunemba okuphezulu, isivinini, kanye nekhono lokwenza inqubo ngaphandle kokubangela umonakalo omkhulu wokushisa ezintweni ezizungezile.
Ngaphezu kwalokho, ama-microwave asetshenziswa ezintweni zokomisa nokushisa kuzo zonke izimboni. Isibonelo, embonini yokudla, ama-microwave asetshenziselwa ukufudumeza nokomisa imikhiqizo ngokushesha, okwandisa umkhiqizo kanye nokusebenza kahle kwamandla.
Izinhlelo zokuhlola ezingabhubhisi (NDT) nazo zisebenzisa amaza kagesi ukuhlola ubuqotho bezinto nezinto ngaphandle kokuzilimaza. Amasu afana nokuhlolwa kwamanje kwe-eddy kanye ne-ultrasonics asebenzisa amaza kagesi ukuthola amaphutha angaphakathi noma ukungahambisani kwezinto.
Ubuchwepheshe bolwazi nokuxhumana
Ebuchwephesheni bolwazi nokuxhumana, amaza kagesi adlala indima ekuthuthukisweni kwamanethiwekhi ekhompyutha, i-inthanethi, kanye nokuxhumana kwesathelayithi. I-fiber optics, esebenzisa ukukhanya (amaza kagesi kagesi ku-spectrum ebonakalayo) ukudlulisa idatha ngesivinini esikhulu ngezintambo ze-fiber-optic, ishintshe indlela esithumela futhi sithola ngayo ulwazi.
Ubuchwepheshe be-Wi-Fi ne-Bluetooth buvumela amadivayisi ukuthi axhumane ngaphandle kwentambo esebenzisa amaza omsakazo. I-Wi-Fi isebenzisa amaza e-microwave ukuxhuma amadivayisi kwi-inthanethi ngaphandle kwentambo, kuyilapho i-Bluetooth ivumela ukushintshaniswa kwedatha okufushane phakathi kwamadivayisi.
Ukuxhumana ngesathelayithi kungenye indlela ebalulekile, evumela ukudluliswa kwedatha ebangeni elide kanye nezinsizakalo ze-GPS zokuzulazula. Amasathelayithi asebenzisa amaza e-microwave ukudlulisa amasignali eMhlabeni nangemuva, ahlinzeka ngezinsizakalo zokuxhumana ezibalulekile ezindaweni ezikude noma ngesikhathi sezinhlekelele zemvelo.
Imvelo kanye nesimo sezulu
Amagagasi kagesi nawo asetshenziswa ekuqapheni imvelo kanye nasezifundweni zesimo sezulu. Amasathelayithi esimo sezulu asebenzisa amagagasi kagesi ukuqoqa idatha mayelana nomkhathi, ulwandle, kanye nomhlaba. Ubuchwepheshe obufana nokuzwa kude busebenzisa amaza ahlukahlukene (i-infrared, i-ultraviolet, kanye nama-microwave) ukuqondisa izinguquko zemvelo nokuqapha imisebenzi yabantu ethinta imvelo.
I-radar yesimo sezulu, esebenzisa ama-microwave, ingakwazi ukubona imvula, umoya, kanye nokwakheka kwesiphepho, isize ekubikezeleni isimo sezulu futhi inikeze isixwayiso kusenesikhathi ngezinhlekelele zemvelo. Lobu buchwepheshe bubalulekile ekunciphiseni izinhlekelele kanye nokuthuthukisa amasu okuzivumelanisa nesimo sezulu.
Ngaphezu kwalokho, ubuchwepheshe be-lidar (Ukuthola Ukukhanya Nokulinganisa) busebenzisa ukukhanya kwe-laser ukukala ibanga nokuqoqa idatha ye-topographic. Lokhu kusiza ezifundweni ze-geological, imephu yamahlathi, kanye nokuqapha ukuguguleka kwenhlabathi.
I-Penutup
Ukusetshenziswa kwamagagasi kagesi kushintshe imikhakha ehlukahlukene yokuphila kwabantu, kusukela kwezokuxhumana kuya kwezokwelapha, imboni, ubuchwepheshe bolwazi, kanye nemvelo. Ngokuqhubeka nokuthuthukiswa kocwaningo kanye nokusungula izinto ezintsha kwezobuchwepheshe, ukusetshenziswa kwamagagasi kagesi kuzokhula futhi kuhlinzeke ngezinzuzo ezinkulu emphakathini. Ubuchwepheshe besikhathi esizayo obufana ne-5G kanye ne-Internet of Things (IoT) kulindeleke ukuthi buthembele kakhulu kumagagasi kagesi ukuxhuma amadivayisi nezinhlelo ngezindlela ezisebenza kahle neziguquguqukayo. Amandla aphelele amagagasi kagesi kagesi awakahlolwa ngokugcwele, futhi ikusasa lithembisa ukuthuthuka okukhulu emikhakheni ehlukahlukene okuzoguqula indlela esiphila futhi sisebenza ngayo.
