Lub cathode glow tshwm sim los ntawm kev lwj ntawm lub zog excitation ntawm cov ions zoo ntawm kev nruab nrab. … Qhov kawg ntawm qhov tsis zoo glow sib raug rau qhov ntau ntawm cov hluav taws xob uas muaj lub zog txaus los tsim kev zoo siab, thiab hauv qhov chaw tsaus ntuj Faraday cov electrons ib zaug ntxiv zog thaum lawv txav mus rau qhov anode.

Vim li cas Faraday qhov chaw tsaus?

Faraday qhov tsaus ntuj

As cov electrons poob zog, tsawg lub teeb tawm, ua rau lwm qhov tsaus ntuj.

Vim li cas lub raj tso tawm kom pom tsaus ntuj thaum khiav tawm mus rau qhov siab qis?

Ib lub raj xa tawm tshwm tsaus nti thaum khiav tawm mus rau qhov tsis tshua muaj siab. … Vim tias ntawm qis siab, kev sib tsoo ntawm electrons thiab molecules ua qis heev. Cov molecules nyob twj ywm unexcited thiab li no, lawv tsis emission tej teeb.

Vim li cas lub raj xa hluav taws xob ci tab sis tsis yog lub raj hluav taws xob cathode?

Cov electrons hauv cov raj no txav mus rau hauv cov txheej txheem qeeb qeeb, tsis tau nce nrawm, yog li cov hlab no tsis tsim cov kab hluav taws xob cathode. Hloov chaw, lawv tsim cov yeeb yuj ci tawm (raws li nyob rau hauv lub teeb neon niaj hnub), ua rau thaum cov hluav taws xob ntaus cov roj atoms, zoo siab rau lawv lub orbital electrons mus rau qib siab dua.

Vim li cas plasmas ci?

Lub glow discharge regime tshuav nws lub npe rau qhov tseeb tias cov ntshav luminous. Cov roj glows vim cov hluav taws xob hluav taws xob thiab cov xov tooj ceev yog siab txaus los ua kom pom lub teeb pom kev los ntawm kev sib tsoo. … Qhov notxhais tau hais tias lub plasma yog nyob rau hauv kev sib cuag nrog tsuas yog ib feem me me ntawm lub cathode nto ntawm qis tam sim no.
