Ib plasma yog ib qho hluav taws xob them rojHauv plasma, qee qhov hluav taws xob tau raug tshem tawm ntawm lawv cov atoms. Vim hais tias cov khoom (electrons thiab ions) hauv plasma muaj cov nqi hluav taws xob, cov lus tsa suab thiab kev coj cwj pwm ntawm plasmas cuam tshuam los ntawm hluav taws xob thiab hlau nplaum.
Puas plasma yog kua lossis roj?
Ib lub plasma muaj qee qhov tshwj xeeb uas ua rau cov kws tshawb fawb sau tias nws yog "theem plaub" ntawm qhov teeb meem. Lub plasma yog kua dej, zoo li cov kua lossis roj, tab sis vim yog cov khoom siv hluav taws xob muaj nyob hauv cov ntshav, nws teb rau thiab tsim hluav taws xob hluav taws xob.
Puas plasma thiab roj tib yam?
Zoo ib yam li roj, plasma tsis muaj qhov tseeb lossis ntim. Nws puv qhov chaw muab. Qhov txawv yog tias, txawm tias nws nyob hauv lub xeev roj, ib feem ntawm cov khoom yog ionized hauv cov ntshav. Yog li ntawd, plasma muaj cov nqi them zoo li cov ions zoo thiab tsis zoo.
Lub xeev ntawm cov teeb meem dab tsi yog plasma?
Plasma hu ua plaub lub xeev ntawm cov teeb meem tom qab khoom, kua, thiab roj. Nws yog ib lub xeev ntawm cov teeb meem nyob rau hauv uas ib tug ionized tshuaj ua heev hluav taws xob conductive mus rau lub point uas ntev-ntau hluav taws xob thiab magnetic teb dominate nws tus cwj pwm.
Cov pa roj dab tsi ua rau ntshav ntshav?
9.2 Plasma Reaction nrog Polymer Surfaces
- Inert gas plasmas - Helium, neon, thiab argon yog peb cov roj inert siv hauv plasma thev naus laus zis, txawm hais tias argon yog qhov ntau tshaj vim nws tus nqi qis.
- Oxygen-muaj plasmas - Oxygen thiab oxygen-muaj plasmas feem ntau yog siv rau kev hloov kho cov chaw polymer.
