Zvikamu zveParabolic Conic: Zvivakwa, Mashandisirwo, uye Kukosha Muhupenyu Hwezuva Nezuva
Pendauluan
Zvikamu zveConic inyaya inonakidza mumasvomhu, kunyanya mu geometry. Kune mhando huru ina dzezvikamu zveconic: madenderedzwa, ma ellipses, ma parabola, uye ma hyperbolas. Muchinyorwa chino, tichanyatsoongorora imwe yemhando dziri nyore dzezvikamu zveconic, asi imwe ine mashandisirwo akawanda akakosha: parabola.
Tsanangudzo uye Zvimiro zveParabola
Parabola ikombama inoumbwa nekusangana kwendege nekoni kana ndege yacho yakaenzana nedivi rimwe rekoni. MuCartesian coordinates, parabola inogona kutsanangurwa nemasvomhu nechimiro chakajairwa che quadratic equation y = ax² + bx + c, apo a, b, na c vari ma constant ane a≠0.
Zvimwe zvinhu zvakakosha zve parabola ndeizvi:
1. Kuenzana: Parabola ine axis of symmetry inoiparadzanisa kuita hafu mbiri dzakafanana. Iyi axis of symmetry mutsetse wakamira unopfuura nepakati pe vertex yeparabola.
2. Nhevedzano: Nhevedzano yeparabola ndiyo nzvimbo inochinja parabola kubva pakukwira kuenda pakudzika (kana kuti zvinopesana). Nzvimbo yenhevedzano inogona kuwanikwa uchishandisa fomura -(b/2a).
3. Kutungamira kweParabola: Kana coefficient a iri mu parabola equation iri positive, curve inovhurika kumusoro. Kana coefficient a iri negative, curve inovhurika pasi.
4. Focus neLatis Rectum: Parabola ine focus point ne latis rectum line zvakabatana ne focus iyi. Focus ndiyo poindi imwe chete iri pa curve iyo ray dzese dzinouya dzakafanana dzichaonekwa.
Kushandiswa kweParabola muhupenyu hwezuva nezuva
Maparabola haangowanikwe mumabhuku emasvomhu kana muzvidzidzo zvejometri chete; anowanikwawo mumabasa akawanda anoshanda zuva nezuva. Heano mimwe mienzaniso:
1. Parabolic Reflector: Imwe yenzira dzinozivikanwa dzekushandisa parabolic dish ndeyekugadzira parabolic reflectors, dzakadai se satellite dish dzeTV ne satellite dish. Parabolic mirror dzinoshandiswa nekuda kwekugona kwadzo kutarisisa chiedza kana mafungu eredhiyo panzvimbo imwe chete iri pamberi padzo. Izvi zvinoshandiswawo mumarambi nemwenje kuti zvitarise mwenje panzvimbo imwe chete.
2. Nzira yeKupfura: Mufizikisi, kufamba kwechinhu chakakandwa kana kupfurwa pasi pesimba regiravhiti, pasina simba remhepo, kunotsanangura parabolic curve. Izvi zvakakosha zvikuru mumunda we ballistics kuti uone nzira yekufamba kwezvipfura, zvakaita semabara, mabhora emitambo, mafireworks, nezvimwewo.
3. Kugadzira Magadzirirwo Ezvivakwa: Zvimwe zvivakwa zvinoshandisa maumbirwo ekufananidzira mumagadzirirwo azvo kuti zvive zvakanaka uye kuti zvivakwa zvigadzikane. Muenzaniso mumwe iSt. Louis Gateway Arch muUnited States.
4. Mashandisirwo muUinjiniya: Muinjiniya yezvivakwa neinjiniya yezvivakwa, maparabola anoshandiswa mukugadzira mabhiriji ekumisikidza nematenga ezviyeuchidzo. Maparabola anoshandiswawo muzvivakwa zvebhiriji nekuda kwekugovera kwavo mutoro zvakanaka.
5. Masisitimu Ekuona: Mumasisitimu ekuona akadai sematelesikopu ekuona nemaikorosikopu ekuona, magirazi ekuona nekuona anoshandiswa kutarisisa chiedza uye kugadzira mifananidzo yakajeka.
6. Kugadzira Magirazi: Mukugadzira magirazi, nheyo dzekufananidzira dzinoshandiswa kugadzirisa kukanganisa kwemufananidzo uye kuvandudza kugona kwemufananidzo, kunyanya mumagirazi ekamera nemidziyo yemifananidzo yepamusoro.
Parabola muTekinoroji Yemazuva Ano
Sezvo tekinoroji ichifambira mberi, kushandiswa kwema "satellite dish" kwakawedzera munzvimbo dzakasiyana dzesainzi neinjiniya. Heano mimwe mienzaniso:
1. Sisitimu Yekutaurirana:
Maantenna eparabolic anoshandiswa muhunyanzvi hwekutaurirana kubva kumaantenna esatellite kusvika kune network dzenharembozha. Mumaantenna esatellite, dhizaini yeparabolic inobvumira kugamuchira masaini kwakasimba uye kwakasimba. Izvi zvakakosha pakutaurirana kweredhiyo, terevhizheni, uye satellite internet, izvo zvinoda kugamuchira nemasaini nemazvo.
2. Sisitimu Yekudzora Otomatiki:
Mukushanda kwemaindasitiri otomatiki, maparabola anoshandiswa sechikamu chekugadzira masisitimu ekutonga. Mumarobhoti, maparabola anogonesa kutsvaga nzira chaiyo uye mafambiro akatsetseka.
3. Simba Rinodzokororwa:
Maradiyo eparabolic anoshandiswawo mumakontena ezuva kugadzira simba. Makontena ezuva anoshandisa magirazi eparabolic kuisa chiedza chezuva panzvimbo imwe chete, zvichidziisa mvura inozoshandiswa kugadzira magetsi. Izvi zvinoderedza kushandiswa kwemafuta efossil uye inhanho yekusimudzira simba.
Mhedziso
Parabola rudzi rwechikamu checonic chine mashandisirwo akawanda anoshanda muhupenyu hwezuva nezuva uye tekinoroji yemazuva ano. Kubva kune zvinoratidzira uye ma antenna eparabolic kusvika kuzvivakwa zvezvivakwa uye masisitimu e optical, parabola inoita basa rakakosha muminda yakasiyana-siyana. Chimiro chayo chiri nyore asi chinoshanda chinoita kuti ive nyaya inonakidza yekutsvagisa mumasvomhu nefizikisi. Uyezve, kunzwisisa hunhu hweparabola kunokosha mukugadzirisa matambudziko akasiyana-siyana anoshanda musainzi neinjiniya. Kuburikidza nekutsvaga kwakawanda, mashandisirwo eparabola anoramba achikura uye achinatswa sezvo tekinoroji neruzivo rwevanhu zvichifambira mberi.
