Doppler kushanda

The Doppler nezvinozoitika ndeimwe hunoshamisa matongo ari kudzidza zvivako rokuchengeta zvakavapo. Its yezvisikwa hunhu anosarudza zviri nhasi kwakavakirwa izvi zviri zvuuru siyana mano akasiyana pazvinoitwa kwevanhu. Chiitiko, iyo panguva iyoyo ainzi kuremekedza ayo akawana, yakanga yakawanikwa pedyo yeAustria yefizikisi Christian Doppler sezvo mangwanani nemakore namapfumbamwe remakore. Doppler kuyerwa vakaperekedza ehupfumi mafungu inowanikwa mugamuchiri pamusoro chinjwa uye mira mabviro.

Kana tikafunga Doppler maturo ari nyore chimiro, zvinofanira kucherechedzwa kuti mumuviri chakajairika anorondedzera kuchinja kakawanda chiratidzo pamusoro chitsama kwebasa panobva chiratidzo kubva mugamuchiri kuti origamuchira. Somuenzaniso, imwe chinozunguzirwa unobva pane kupi, uye iro rine zvimwe yakamisirwa maitikiro ichanzwiwa, kubudikidza mugamuchiri kare pamusoro yakasiyana kakawanda kana panguva yaro ndima kunobva uye mugamuchiri vakachinja nzvimbo hama mumwe, kuti Uchibviswa. Mumufananidzo uyu kuchawedzera kana kakawanda kuderera kunobva mirayiridzo umo kunobva kunoita hama kuti receiver. Akapiwa Doppler chaizvoizvo hatigoni kutaura kuti kana mugamuchiri kunoita kubva kupi - kukosha chinozunguzirwa maitikiro kunoderedza. Kana mugamuchiri riri pedyo chinozunguzirwa nemwaranzi panobva, chiyero kakawanda zvinozunguzirwa inowedzerawo. Saka, kubva mitemo iyi zvinonzi vakagumisa kuti kana anopa nemafungu uye mugamuchiri panguva ndima yayo haina kuchinja nzvimbo yayo, ipapo kukosha chinozunguzirwa kakawanda achagara zvakafanana.

Anokosha uye mumwe muvaravara iyo inechirevo Doppler maturo. pfuma iyi iri pamwero ari kupokana mitemo relativity. Chokwadi kuti kakawanda kuchinja kunotemwa kwete chete nokuita kana asiri mugamuchiri zvitubu nemwaranzi, uye kuti chinofamba. Kuyerwa zvakaratidza kuti kakawanda kusuduruka kunotemwa umo imwe chinjwa chinhu, zvikuru kuoneka, ikava duku siyana pamusoro mugamuchiri uye kusasarura panobva velocities pamusoro velocity chinozunguzirwa sangano. Kutaura zvazviri, mune zviitiko apo pane nekuratidza Doppler maturo, hapana kupokana nedzidziso yokuti relativity haaratidzi kumusoro, nokuti pano zvakakosha kwete hama kwebasa mugamuchiri anokonzera uye hunhu kufamba mafungu ane kwakavharwa nenyama unosvikirwa umo chinofamba.

Kwakadaro ehupfumi Doppler kwepasi kunooneka muna ukama acoustic mafungu mavambo, uye kune remagetsi mafungu, asi kuti panyaya remagetsi namafungu maitikiro zvaizopedza Fani hakubvi kunobva kana mugamuchiri unotii.

Izvi zviri nani tiivistelmä anoita, ona, zvisinei, zviri nyore. Somuenzaniso, Doppler kushanda muna acoustics kuonekwa, kuti munoreva - kunzwa, panguva apo chimire kuwandisa kwemotokari, ukanzwa sairini nekusarangarira zvashata nemotokari. Chokwadi vose akacherechedza kuti kana motokari kwakadaro kusvika - kurira sairini rinonzwika imwe nzira mukuru, uye kana motokari parichakukundai - kurira sairini pazasi. It chete anosimbisa kuchinja tsika kakawanda pakati acoustic chiratidzo.

Great kukosha Doppler maitikiro pakutibatsira radar, nokuremekedza remagetsi mafungu. Pahwaro iri kushanda basa radars zvose uye zvimwe namano kuziva zvinofamba zvinhu zvikuru zvakasiyana-siyana minda mabasa evanhu.

ehupfumi ayo anoshandiswa muruzivo rwokurapa nokuda kutsunga ropa kuyerera, sokuziva, kwakadaro nzira sezvo Doppler echocardiography. Pahwaro ari Doppler maturo, akavaka ngarava midziyo midziyo pemvura, nekushandisa ayo meteorologists chiyero mhepo simba uye kumhanya kufamba yegore zvavo.

Kunyange zvake zvomuchadenga kuyerwa kushandisa Doppler maturo. Saka, chikuru kuchinja kubva spectra zvinhu yokudenga siyana, tsunga avo mwero kufamba muchadenga, zvikurukuru, chaiyo nokuda izvi kwave hypothesized kuwedzera muchadenga.
