Luminous flux txawv ntawm lub zog (radiant flux ) hauv qhov ci ntsa iab ntawd flux suav nrog txhua qhov hluav taws xob hluav taws xob tawm, thaum luminous flux yog qhov hnyav raws li tus qauv (a " luminosity muaj nuj nqi ") ntawm tib neeg lub qhov muag rhiab heev rau ntau yam wavelengths. Lumens muaj feem xyuam rau lux nyob rau hauv uas ib tug lux yog ib tug lub lumen ib square meter.
Raws li, lub teeb ci ntsa iab txhais li cas?
Luminous flux yog ntsuas qhov ci ci ntawm a lub teeb qhov chaw hais txog lub zog raug tso tawm. Luminous flux SI SI units, yog ntsuas nyob rau hauv lub lumen (lm).
Ib yam li ntawd, lub teeb ci li 750 lumens? Txhawm rau pab koj kom tau txais lub tswv yim ntawm lub lumen scale, tus qauv 60-watt teeb tso tawm ib ncig 750 -850 lub lumens ntawm lub teeb Yog tias koj xaiv qhov muag teev rau teeb pom kev ua haujlwm, nrhiav qhov muag nrog 1000 lub lumens lossis ntau dua.
Ib yam nkaus, tib neeg nug, pes tsawg lumens nyob hauv Lux?
Lux yog ib chav ntsuas ntawm lub teeb uas qhov chaw kuj raug coj mus rau hauv tus account. 1lux ua 1 Lumen /m2, ua lwm yam lus - kev siv lub teeb nyob hauv ib cheeb tsam tshwj xeeb. Lux yog siv los ntsuas tus nqi ntawm lub teeb tso zis hauv ib cheeb tsam. Ib lux yog sib npaug rau ib lumn ib square meter.
SI unit ntawm luminous flux yog dab tsi?
Cov SI chav ntawm cov teeb pom kev zoo yog lumen (lm). Ib lub lumen yog txhais raws li luminous flux ntawm lub teeb tsim los ntawm lub teeb ci uas emits ib lub candela ntawm luminous siv zog hla lub kaum ntse ntse ntawm ib tus steradian. Hauv lwm qhov system units , luminous flux tej zaum muaj chav nyob ntawm lub zog.

7506 yog Osram tus lej rau hom P21W teeb. P21W thiab 1156 zoo sib xws. Lawv tsis zoo ib yam, tab sis lawv muaj peev xwm hloov pauv tau nyob rau ntau qhov xwm txheej ntev npaum li 1156 ib qho siv tau muaj lub hauv paus nickel-plated thiab tsis yog tooj dag dawb
Puas yog tag nrho 209 tus primers zoo ib yam?
Tsis yog, tag nrho 209 primers tsis zoo ib yam thiab tsis tuaj yeem hloov tau willy-nilly
Puas yog cov coolant thiab antifreeze zoo ib yam?
Antifreeze feem ntau yog siv los ua ib qho ntawm cov khoom sib xyaw ua kom txias - qhov dej txias feem ntau yog 50-50 sib cais ntawm cov tshuaj tiv thaiv kab mob thiab dej. Antifreeze (tshwj xeeb yog ethylene glycol, uas yog nws lub hauv paus tseem ceeb) yog siv los txo qis qhov khov ntawm cov kua uas ncig ncig lub cav ntawm lub tsheb
Puas yog hluav taws kev lav phib xaub zoo ib yam li kev puas tsuaj rau cov tsev xauj tsev?
Npog Txoj Cai Luag Haujlwm Xwb Tsuas yog Kev pov hwm kev puas tsuaj rau hluav taws uas tau muab nyob rau hauv Kev Puas Tsuaj Rau Lub Tsev Rotten Rau Koj siv tsuas yog koj raug cai raug cai rau kev puas tsuaj. Ntawd yog, qhov hluav taws kub puas tsuaj rau koj lub tsev (lossis nyob hauv) thaj chaw yuav tsum yog los ntawm koj qhov tsis saib xyuas
Puas yog lub chaw tso tsheb puas yog tib yam li kev lav phib xaub?
Yog tias tus neeg siv khoom plam thiab poob rau hauv qhov chaw pabcuam hauv av, kev lav phib xaub yuav tuaj nqa qhov xwm txheej no. Kev lav ris rau tsheb, ntawm qhov tod tes, nthuav dav txoj cai kev lav phib xaub dav dav rau cov tsheb uas tau siv nyob hauv thaj tsam ntawm kev lag luam, lossis uas yog nyob hauv kev saib xyuas, saib xyuas, thiab tswj hwm koj lub lag luam
