A multimeter los yog ib tug multitester, tseem hu ua VOM (volt-ohm-milliammeter), yog ib qho khoom siv hluav taws xob ntsuas uas sib txuas ntau yam kev ntsuas hauv ib chav. Ib yam multimeter tuaj yeem ntsuas qhov voltage, tam sim no, thiab tsis kam. Analog multimeters siv lub microammeter nrog lub pointer txav los tso saib kev nyeem ntawv.
Ua raws li qhov no hauv kev xav, dab tsi yog kev siv multimeter?
A Multimeter yog ib qho khoom siv hluav taws xob, txhua tus kws tshaj lij hluav taws xob thiab cov kws tsim khoom siv dav siv cov khoom siv ntsuas. Multimeter Feem ntau yog siv los ntsuas peb qhov yooj yim hluav taws xob yam ntxwv ntawm voltage, tam sim no thiab tsis kam. Nws tseem tuaj yeem siv los ntsuas kev txuas ntxiv ntawm ob lub ntsiab lus hauv hluav taws xob hluav taws xob.
Tsis tas li ntawd, cov haujlwm ntawm digital multimeter yog dab tsi? A digital multimeter los yog DMM yog ib qho tseem ceeb tshaj plaws ntawm cov khoom siv kuaj ntsuas hluav taws xob los yog hluav taws xob teeb meem. Nws yog ib qho cuab yeej ntsuas uas siv cov ntaub ntawv analog thiab hloov mus rau hauv ib qho digital teeb liab uas nyeem tawm ntawm cov zaub.
Kuj tseem paub yog, multimeters ua haujlwm li cas?
Ib qho ammeter ntsuas tam sim no, ohmmeter tso cai rau koj los txiav txim siab tsis kam, thiab voltmeter yog siv los ntsuas qhov voltage ntawm ob lub ntsiab lus. Multimeters muab tag nrho peb lub luag haujlwm hauv ib lub cuab yeej. Ib qho hluav taws xob hluav taws xob yuav muaj qhov tsis kam ntawm xoom lossis zero ohms yog tias nws luv luv.
Dab tsi yog kev ua haujlwm ntawm multimeter thiab fais fab mov?
Fluke27 yog ib qho khoom siv uas tuaj yeem ntsuas qhov txuas ntxiv, tsis kam, voltage thiab tam sim no rau ob qho tib si ncaj qha tam sim no (DC) thiab hloov tam sim no (AC). Cov muaj nuj nqi ntawm multimeter raug xaiv siv 12- txoj haujlwm tig hloov.

Dab tsi ntawm pipette yog volumetric thiab nws siv rau dab tsi?
Lub volumetric pipette, noob pipette, lossis lub plab pipette tso cai rau kev ntsuas qhov tseeb (rau plaub qhov tseem ceeb) ntawm qhov ntim ntawm cov tshuaj. Volumetric pipettes feem ntau yog siv rau hauv analytical chemistry los ua cov kev daws teeb meem los ntawm lub hauv paus Tshuag thiab npaj cov kev daws teeb meem rau titration
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 reagents xav tau rau PCR thiab dab tsi yog qhov ua haujlwm ntawm txhua tus?
Muaj tsib yam tshuaj reagents, lossis cov khoom xyaw, siv hauv PCR: qauv DNA, PCR primers, nucleotides, PCR tsis thiab Taq polymerase. Primers feem ntau yog siv nyob rau hauv khub, thiab DNA ntawm ob lub primers yog amplified thaum lub sij hawm PCR cov tshuaj tiv thaiv
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
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
