A deflection yoke yog ib hom hlau nplaum sib nqus, siv nyob rau hauv cathode ray raj los luam theej duab hluav taws xob ob qho tib si vertically thiab horizontally hla tag nrho lub vijtsam. … Los ntawm kho lub zog ntawm lub nqaj tam sim no, qhov ci ntawm lub teeb uas tsim los ntawm phosphor ntawm lub vijtsam tuaj yeem sib txawv.
Tus quab deflection yog dab tsi?
Lub liner yog ua los ntawm ob daim ntawv polypropyleneuas thaum snapped ua ke, tsim lub khob hliav qab. Hauv cathode ray tube (CRT) deflection yoke, sab hauv ntawm lub khob hliav qab ua raws li daim ntawv coil rau ob kab rov tav deflection coils.
Lub hom phiaj ntawm daim phiaj deflection hauv CRT yog dab tsi?
Cathode ray tube siv cov phaj deflecting rau kev hloov pauv txoj kev ntawm electrons. Cov electrons tom qab tawm los ntawm rab phom electron dhau los ntawm deflecting daim hlau. CRT siv daim phiaj ntsug thiab kab rov tav los tsom rau cov kab hluav taws xob.
Puas muaj pes tsawg daim hlau deflection muaj nyob hauv CRT?
Muaj ob teeb ntawm cov hlau deflection: ntsug thiab kab rov tav (Daim duab 3). Txhua daim phiaj yog sib npaug thiab nyob ntawm lub caj dab ntawm lub raj.
Puas yog cathode ib ray?
Cathode rays (tseem hu ua electron beam lossis e-beam) yog kwj ntawm electrons pom hauv cov raj nqus tsev. … Cov kab hluav taws xob cathode muaj npe vim tias lawv tau tawm los ntawm cov hluav taws xob tsis zoo, lossis cathode, hauv lub tshuab nqus tsev. Txhawm rau tso cov electrons rau hauv lub raj, lawv yuav tsum ua ntejcais tawm ntawm lub atom ntawm lub cathode.
