Argon gas yog siv nyob rau hauv fluorescent thiab incandescent qhov muag teev kom tsis txhob muaj oxygen nyob rau hauv lub qhov muag teev los ntawm corroding lub kub tungsten filament. Kev siv ntawm argon hauv qhov muag teev tiv thaiv cov evaporation ntawm tungsten filaments, uas ua rau muaj zog lub teeb lub neej.
Nyob rau hauv txoj kev no, yog vim li cas noble gases siv nyob rau hauv hluav taws xob qhov muag teev?
Helium , neon, argon thiab krypton yog siv hauv gas Tshem tawm cov teeb pom kev zoo nkauj, hu ua "neon" teeb . Argon yog siv kom puv incandescent qhov muag teev inhibit qhov evaporation ntawm tungsten filaments thiab nce noob lub neej. Qhov ntom ntawm cov cov pa roj nce nrog nce molecular mass.
Ib yam li ntawd, dab tsi yog siv los ua lwm txoj hauv kev rau argon hauv qhov muag teev? Nitrogen yog siv -chemically inactive thaum muaj nyob rau hauv nws lub xeev diatomic (N2). Cov no yog siv los tiv thaiv oxidation ntawm filament nyob rau hauv lub noob.
Tsis tas li ntawd, yog vim li cas argon roj siv nyob rau hauv lub teeb tab sis tsis yog cua?
Lub kaw iav chamber ntawm lub noob muaj, inactive (inert) gas , Argon . Lub iav chamber tsis tuaj yeem sau nrog huab cua Raws li lub xub ntiag ntawm oxygen yuav ua rau cov filament hlawv, i.e. react nrog oxygen. Ib qho obviously, inert gas yuav tsis hnov mob nrog filament. Nitrogen kuj yog siv nyiam argon.
Dab tsi yog kev siv argon?
Argon yog siv nyob rau hauv qee hom arc vuam xws li roj hlau arc vuam thiab roj tungsten arc vuam, nrog rau hauv kev ua cov titanium thiab lwm yam reactive hais. Ib argon Cov huab cua kuj tseem siv rau kev loj hlob muaju ntawm silicon thiab germanium.

Vim li cas cov hluav taws xob sab nraud tsuas yog suav nrog hauv daim duab kos duab hluav taws xob?
Atoms nrog 5 los yog ntau tshaj valence electrons tau electrons tsim ib tug tsis zoo ion, los yog anion. Vim li cas thiaj li cov hluav taws xob sab nraud tsuas yog cov uas suav nrog hauv daim duab orbital filling? lawv tsuas yog cov uas koom nrog cov tshuaj tiv thaiv thiab kev sib raug zoo. 2s orbital nyob deb ntawm lub nucleus txhais tau tias nws muaj zog ntau dua
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
Dab tsi yog kauj ruam transformers siv hauv kev xa hluav taws xob hluav taws xob?
Cov hluav taws xob hluav taws xob tau xa mus rau qhov ntev ntawm qhov hluav taws xob siab. Yog li, cov kauj ruam nce transformers yog siv ntawm cov chaw nres tsheb fais fab kom nce qhov hluav taws xob ntawm lub zog whereas cov kauj ruam-down transformers yog siv los txo qhov voltage mus txog 220 V
Dab tsi yog qhov zoo ntawm kev siv lub tshuab hluav taws xob hloov hluav taws xob hauv atomic absorption?
Qhia qhov zoo thiab qhov tsis zoo ntawm lub cub tawg piv nrog kev siv cov nplaim taws hauv atomic absorption spectroscopy. Cov txiaj ntsig tseem ceeb yog ntau dua rhiab heev (concentration thiab tshwj xeeb tshaj yog loj). Lub ntsiab tsis zoo yog cov cuab yeej cuab tam ntau dua thiab cov nqi ntsuas
