Kev txhais: Cov nyhuv Thermionic lossis Thermionic Emission tuaj yeem txhais tau tias yog tshwm sim uas cov hluav taws xob tawm ntawm cov hlau thaum tshav kub siv rau cov hlau.
Dab tsi yog qhov tshwm sim ntawm cov thermionic emission?
Thermionic emission yog qhov emission ntawm electrons los ntawm cov hlau rhuab (cathode) … Lub zog tau txais los ntawm qhov chaw electrons tso cai rau lawv txav mus deb ntawm qhov chaw yog li ua rau emission.
Dab tsi yog qhov thermionic emission piav qhia kev ua haujlwm ntawm diode?
Daim Ntawv Thov ID: 42551. Thaum cov khoom siv hluav taws xob tawm los ntawm cov cathode rhuab hauv lub dav hlau parallel nqus diode, lawv pab txhawb rau qhov chaw them nqi ceev hauv diode, uas cuam tshuam. hluav taws xob muaj peev xwm faib.
Dab tsi yog qhov tseem ceeb ntawm cov thermionic emission?
Thermionic emissions ntawm electron plays lub luag haujlwm tseem ceeb hauv ob qho tib si physics thiab digital electronic technology. Keeb kwm, qhov kev tshawb pom ntawm thermionic emission ua kom cov kws kho mob tsim cov kab hluav taws xob tsis muaj hluav taws xob hauv lub tshuab nqus tsev.
Richardson tsab cai lij choj yog dab tsi?
Ib lub npe hu ua Richardson txoj cai lij choj (thawj lub tswv yim los ntawm Askiv tus kws kho mob Owen W. Richardson) yog siv tau rau txhua yam hlau. Nws yog feem ntau hais nyob rau hauv nqe lus ntawm emission tam sim no ceev (J) raws li nyob rau hauv amperes ib square meterBoltzmann tas li k muaj tus nqi. Hauv electron tube: Thermionic emission.
