Txij li CFLs tau tsim los muab kev pom dav dav, feem ntau ntawm cov teeb emitted los ntawm CFLs yog nyob rau thaj tsam pom ntawm lub spectrum (kwv yees li 400-700 nm hauv wavelength ). Tsis tas li ntawd, CFLs raug tso tawm me me ntawm UVB (280-315 nm), UVA (315-400 nm) thiab infrared (> 700 nm) hluav taws xob.
Yog li ntawd, qhov wavelengths ntawm lub teeb raug muab tawm los ntawm cov qhov muag teev incandescent?
Incandescent qhov muag teev feem ntau haus ntau zog thiab xwb muab tawm ib qho me me ntawm qhov pom teeb piv rau infrared, uas txhais tau hais tias lawv luminous efficiency yog tsawg heev! Vim lub filament kub heev, iav noob tuaj yeem kub heev thiab (siab txog 400 ° F).
Qhov thib ob, dab tsi yog qhov tshwj xeeb ntawm cov spectrum tau txais rau lub teeb fluorescent dab tsi yog siv nyob rau hauv lub teeb fluorescent? Qhov sib xyaw spectrum ntawm mercury ntxiv rau phosphor yields tus yam ntxwv teeb ntawm a fluorescent noob. Fluorescent teeb hloov ntau tshaj 20% ntawm lub zog hluav taws xob rau teeb , uas yog 10 lub sij hawm ntau npaum li incandescent teeb qhov muag teev.
Tom qab ntawd, lo lus nug yog, qhov spectrum ntawm lub teeb fluorescent yog dab tsi?
Cov fluorescent spectrum muaj teeb wavelengths tsim los ntawm phosphor txheej, uas ib tug ntaus ntawv hu ua ib tug spectrometer ntsuas thiab qhia raws li ib daim duab. Teeb hauv ib yam fluorescent spectrum spikes muaj zog nrog xiav, me ntsis ntsuab thiab liab wavelengths, nrog ob peb variations raws li hom ntawm noob.
Puas yog lub teeb fluorescent txuas ntxiv spectrum?
Cov spectrum ntawm a fluorescent teeb muaj cov kab ci ntsa iab thiab a nruam spectrum . Cov kab ci ntsa iab los ntawm cov roj mercury hauv lub raj thaum lub nruam spectrum los ntawm phosphor txheej txheej txheej sab hauv ntawm lub raj.

Qhov twg tshwm sim thawj lub teeb nyob ntawm qhov tshwm sim lossis lub teeb ywj pheej?
Lub Teeb-Dependent thiab Lub Teeb-Independent Reactions. Cov tshuaj tiv thaiv lub teeb, lossis cov tshuaj tiv thaiv lub teeb-dependent, yog thawj zaug. Peb hu lawv ob leeg thiab ob lub npe. Nyob rau hauv lub teeb-dependent tshwm sim ntawm photosynthesis, lub zog ntawm lub teeb propels lub electrons los ntawm ib tug photosystem mus rau lub high-zog lub xeev
Dab tsi wavelengths ntawm lub teeb zoo tshaj plaws hauv kev tsav tsheb photosynthesis?
Qee qhov liab thiab xiav wavelengths ntawm lub teeb yog qhov zoo tshaj plaws nyob rau hauv photosynthesis vim hais tias lawv muaj raws nraim cov nqi ntawm lub zog rau energize, los yog excite, chlorophyll electrons thiab boost lawv tawm ntawm lawv orbits mus rau ib tug ntau dua lub zog
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Yuav ua li cas koj pom qhov nruab nrab tshaj tawm ntawm qhov tshaj tawm vs lub sijhawm teeb?
Qhov chaw nyob hauv qab qhov nrawm / lub sijhawm nkhaus yog tag nrho cov kev hloov pauv. Yog tias koj faib qhov ntawd los ntawm kev hloov pauv hauv lub sijhawm, koj yuav tau txais qhov nruab nrab tshaj tawm. Velocity yog vector daim ntawv ntawm kev ceev. Yog tias qhov nrawm ib txwm tsis yog qhov tsis zoo, ces qhov nruab nrab tshaj tawm thiab qhov nruab nrab ceev yog tib yam
Qhov twg yog qhov cua sov los ntawm qhov uas ua rau qhov tam sim no convection hauv lub mantle?
Lub tshav kub uas tsav cov convection tam sim no nyob rau hauv lub mantle los ntawm lub hauv paus ntawm lub ntiaj teb
