Hluav taws xob cua sov cua sov txoj kev - nruab nrab cua sov
Siv lub tshuab hluav taws xob ntau zaus kom sov cov khoom siv insulating. Cov khoom cua kub tseem ceeb yog dielectric. Thaum lub dielectric muab tso rau hauv ib qho kev hloov hluav taws xob, nws yuav rov qab polarized (nyob rau hauv qhov kev txiav txim ntawm ib qho hluav taws xob, qhov saum npoo los yog sab hauv ntawm dielectric yuav muaj qhov sib npaug thiab sib npaug), yog li hloov hluav taws xob hauv hluav taws xob rau hauv kub.
Hluav taws xob cua sov cua sov txoj kev-infrared cua sov
Siv cov hluav taws xob infrared los ua kom pom cov khoom. Tom qab cov khoom absorbs infrared, nws hloov lub zog radiant mus rau hauv tshav kub thiab rhuab.
Hluav taws xob cua sov cua sov txoj kev-electron beam cua sov
Qhov saum npoo ntawm cov khoom yog bombarded los ntawm electrons txav ntawm kev kub ceev nyob rau hauv qhov kev txiav txim ntawm ib qho hluav taws xob teb kom sov nws. Lub ntsiab tseem ceeb rau hluav taws xob hluav taws xob hluav taws xob yog lub tshuab hluav taws xob hluav taws xob, tseem hu ua phom hluav taws xob. Cov phom electron feem ntau yog tsim los ntawm cathode, tsom electrode, anode, electromagnetic lens thiab deflection coil. Lub anode yog grounded thiab cathode txuas nrog rau qhov tsis zoo siab txoj hauj lwm. Lub teeb tsom teeb feem ntau yog nyob ntawm tib lub peev xwm raws li cathode, thiab lub zog hluav taws xob nrawm yog tsim los ntawm cathode thiab anode. Cov electrons emitted los ntawm cathode yog ceev mus rau ib tug ceev ceev nyob rau hauv qhov kev txiav txim ntawm ib tug accelerating hluav taws xob teb, tsom los ntawm ib tug electromagnetic lens, thiab ces tswj los ntawm ib tug deflection kauj, thiaj li hais tias lub electron beam yog qhia rau cov khoom yuav tsum tau rhuab nyob rau hauv ib tug. tej kev taw qhia.
Hluav taws xob cua sov cua sov txoj kev-arc cua sov
Siv qhov kub thiab txias uas tsim los ntawm lub arc kom sov cov khoom. Arc yog qhov tshwm sim ntawm cov pa tawm ntawm ob lub electrodes. Qhov voltage ntawm lub arc tsis siab tab sis qhov tam sim no loj heev. Nws muaj zog tam sim no yog tswj los ntawm ntau cov ions evaporated ntawm lub electrode, yog li lub arc yog yooj yim cuam tshuam los ntawm ib puag ncig magnetic teb. Thaum ib qho arc yog tsim los ntawm cov electrodes, qhov kub ntawm arc kem tuaj yeem ncav cuag 3000-6000K, uas yog tsim rau kub kub smelting hlau.
