Los thauj ib lub ntim ntsuas ntawm cov kua
Yog li, koj siv micropipette li cas?
Tuav lub micropipette nrog tus ntiv tes xoo so ntawm lub plunger thiab cov ntiv tes curled nyob ib ncig ntawm lub cev. Nias tus ntiv tes xoo kom txog thaum Txoj Haujlwm 2 mus txog. Khaws lub plunger ntawm txoj hauj lwm thib ob, tso lub taub hau txuas mus rau qhov kawg ntawm qhov micropipette hauv qab ntawm cov kua dej yuav tsum tau kos.
vim li cas pipettes tseem ceeb? Micropipettes yog feem ntau tseem ceeb thiab cov cuab yeej tshiab tshaj plaws rau lub chaw soj nstuam. Muaj ntau ntau hom kev sim thiab nyob rau hauv tag nrho cov neeg yuav tsum tau ua hauj lwm nrog cov kua thiab semi kua. Pipettes yog cov khoom siv uas tuaj yeem pab koj tshaj plaws hauv cov txheej txheem tag nrho ntawm kev sim thiab kev sim hauv chav kuaj.
Tib neeg kuj nug, dab tsi yog siv ob qhov chaw nres tsheb hauv micropipette?
Micropipettes ua haujlwm los ntawm huab cua hloov chaw. Tus neeg teb xov tooj depresses lub plunger uas txav lub piston sab hauv mus rau ib qho ntawm ob txawv txoj hauj lwm. Thawj nres yog siv kom puv micropipette tip, thiab thib ob nres yog siv kom dispense cov ntsiab lus ntawm lub ntsis.
Dab tsi yog qhov chaw ntawm micropipette?
Cheebtsam ntawm Micropipette Basic ib feem ntawm micropipette muaj xws li plunger khawm, ntsis ejector khawm, ntim hloov dial, ntim zaub, taub ejector, thiab ncej. Lawv txawv nyob rau hauv tsim, hnyav, plunger quab yuam, thiab tag nrho precision.

Dab tsi yog qhov kev txawj ntse ntawm qhov pom kev siv rau?
Spatial peev xwm los yog visuo-spatial muaj peev xwm yog lub peev xwm to taub, laj thawj, thiab nco ntsoov qhov kev sib raug zoo ntawm cov khoom lossis qhov chaw. Visual-spatial peev xwm yog siv rau txhua hnub siv los ntawm kev taw qhia, kev nkag siab lossis kho cov cuab yeej, kev nkag siab lossis kwv yees qhov deb thiab ntsuas, thiab ua haujlwm ntawm kev ua haujlwm
Dab tsi yog kev siv cov saw hlau nuclear siv rau?
Nuclear chain reaction. Nuclear chain reactions yog cov tshuaj tiv thaiv uas tau txais lub zog nuclear, feem ntau los ntawm nuclear fission. Cov kev cuam tshuam ntawm cov saw hlau no yog qhov muab cov chaw tsim hluav taws xob nuclear nrog lub zog uas tom qab ntawd hloov mus ua hluav taws xob siv los ntawm tib neeg
Dab tsi yog cov kev siv ntawm kev sib koom ua ke?
Ib daim ntawv thov tseem ceeb ntawm kev sib koom ua ke yog lawv siv los ua cov catalysts, uas pab hloov cov tshuaj tiv thaiv kab mob. Qee qhov nyuaj hlau catalysts, piv txwv li, ua lub luag haujlwm tseem ceeb hauv kev tsim cov polyethylene thiab polypropylene
Dab tsi yog qhov teeb meem loj tshaj plaws ntawm kev siv cov kev tshawb fawb txog kev sib raug zoo?
Tej yam tsis zoo los yog kev tshawb fawb txog kev sib raug zoo muaj xws li: a. Lawv tsis tuaj yeem siv los tsim kom muaj kev sib raug zoo-thiab-tshuaj los yog kev coj ntawm kev cuam tshuam
Dab tsi yog qhov sib npaug siv los xam tag nrho cov khoom siv hluav taws xob siv?
Cov mis uas txuas lub zog thiab lub zog yog: Zog = Lub Zog x Sijhawm. Chav tsev ntawm lub zog yog joule, lub zog ntawm lub zog yog watt, thiab chav tsev ntawm lub sijhawm yog qhov thib ob
