Thaum twg krypton ua yog siv hauv halogen noob nws tuaj yeem pab ua qhov lub teeb los ntawm noob purer thiab whiter. Qhov no txhais tau hais tias nws yuav zoo dua rau kev siv teeb pom kev hauv tsev uas qhov xim tseem ceeb.
Yog li ntawd, krypton teeb yog dab tsi?
Krypton /Xenon Feem ntau tus qauv teeb pom kev zoo qhov muag teev tau ntim nrog inert argon ntxiv rau nitrogen txaus los tiv thaiv arcing ntawm cov hlau lead hauv. Krypton thiab xenon roj pab txhawb ob yam uas txhim kho qhov ua tau zoo (lossis kev ua tau zoo) ntawm lub teeb piv rau cov uas muaj argon.
Qhov thib ob, vim li cas neon argon thiab krypton siv rau hauv qhov muag teeb? Helium, neon , argon thiab krypton yog siv nyob rau hauv cov pa tawm hniav zoo nkauj ligthing, hu ua " neon xim " teeb . Argon yog siv kom puv incandescent qhov muag teev los tiv thaiv kev nqus ntawm tungsten filaments thiab nce ntxiv noob lub neej. Xenon yog siv hauv cov raj hluav taws xob rau cov koob yees duab thiab lwm cov raj raj.
Ib yam li ntawd, nws tau nug, vim li cas krypton siv cov teeb ci ci?
Krypton yog siv nrog argon hauv teeb fluorescent txhawm rau txhim kho lawv qhov ci ci thiab nrog nitrogen hauv cov roj teeb teeb mus cuag lawv lub neej. Nws kuj yog siv nyob rau hauv flashbulbs los tsim ib tug heev ci lub teeb rau lub sijhawm luv luv, siv rau kev yees duab nrawm.
Dab tsi yog cov pa hauv lub teeb?
argon roj

Dab tsi ntawm qhov muag teev yuav tsum tau siv hauv chav dej?
Incandescent qhov muag teev: Cov qij no yuav tsum muaj xim "dawb" qhia (sov dawb los yog txias dawb) los yog muaj xim kub ntawm 2700K thiab 3000K. Fluorescent qhov muag teev: Tsis zoo li kev ntseeg nrov, CFL qhov muag teev tuaj yeem yog qhov kev xaiv zoo rau chav dej - tsuav yog lawv cov xim Rendering Index (CRI) yog 90 lossis siab dua
Dab tsi txaus ntshai zoo kawg li nws yog qhov peb yuav tsum tau khawb trenches thiab sim cov roj npog qhov ncauj qhov ntswg ntawm no vim muaj kev sib cav nyob hauv lub tebchaws nyob deb ntawm cov neeg uas peb tsis paub dab tsi?
Qhov txaus ntshai npaum li cas, zoo heev, zoo kawg yog tias peb yuav tsum tau khawb trenches thiab sim roj-qhov ncauj qhov ntswg ntawm no vim muaj kev sib cav nyob rau hauv ib lub teb chaws nyob deb ntawm cov neeg uas peb tsis paub dab tsi. Nws zoo nkaus li tseem tsis yooj yim dua tias kev sib cav uas twb tau hais tseg hauv txoj cai yuav tsum yog kev ua tsov rog
Nyob rau hauv cov nroj tsuag twg photosynthesis tshwm sim nyob rau hauv qia es tsis nyob rau hauv nplooj?
1 Teb. Nyob rau hauv cov nroj tsuag photosynthesis tshwm sim nyob rau hauv chloroplasts. Chloroplast tuaj yeem nyob hauv lub hlwb ntawm cov txiv hmab txiv ntoo, stems, tab sis feem ntau ntawm tag nrho cov nplooj. Hauv qee qhov succulents (xws li cacti), lub ntsiab photosynthetic kev ua haujlwm yog txuam nrog lub qia
Yuav ua li cas tshwm sim thaum lub concentration ntawm qabzib nyob rau hauv cov dej sab nraum lub cell yog siab tshaj qhov concentration nyob rau hauv?
Yog hais tias qhov concentration ntawm qabzib nyob rau hauv dej sab nraud ntawm lub cell yog siab tshaj qhov concentration hauv, dej yuav nyiam tawm hauv lub cell los ntawm osmosis. c. Cov piam thaj yuav zoo li nkag mus rau hauv lub cell los ntawm osmosis
