Cov qhov tseeb ntawm kev ntsuas hluav taws xob txhais tau hais tias kaw tus nqi qhia yog rau tus nqi tseeb ntawm qhov ntsuas qhov ntsuas. Txawm li cas los xij, 10.0 volts ntsuas ntawm 100-V nplai ntawm tib yam voltmeter ntsuas tuaj yeem nyeem ntawm 7 V thiab 13 V, lossis ± 30% ntawm qhov kev nyeem ntawv tiag tiag, thaum lub ntsuas ntsuas yog technically inspecifications.
Ntxiv mus, dab tsi yog qhov tseeb ntawm digital multimeter?
Piv txwv li, ib qhov tseeb ntawm ± (2% + 2) txhais tau hais tias kev nyeem ntawv ntawm 100.0 V ntawm multimeter tuaj yeem yog los ntawm 97.8V rau 102.2 V. Kev siv a DMM nrog siab dua qhov tseeb tso cai rau ntau daim ntawv thov. Basic dc qhov tseeb ntawm Fluke handheld digital multimeters 0.5% mus rau 0.025%.
Ib yam li ntawd, suav hauv digital multimeter yog dab tsi? A 3.5 tus lej multimeter yuav tso saib tag nrho- digital nyeem ntawv uas muaj peb tus lej ntawm 0 txog 9, ntxiv rau 1 lossis 0 ib nrab tus lej; uas yog, kev nyeem ntawv xws li multimeter yog nyob rau hauv qhov ntau ntawm 0.001-1999.
Ntawm no, dab tsi yog qhov ntau ntawm qhov tseeb?
Qhov tseeb , Kev daws teeb meem thiab Ntau yam (txhais tau) Qhov tseeb yog lub peev xwm ntawm kev ntsuas tom qab qhov tseeb tus nqi ntawm qhov ntsuas tau. Kev daws teeb meem yog tus lej ntawm cov lej tseem ceeb (decimal qhov chaw) uas ntsuas qhov ntsuas tau ntseeg tau. Ntau yam yog tus nqi orexent tus nqi yuav ntsuas tau.
RDG txhais li cas hauv qhov tseeb?

Yuav ua li cas koj qhia yog hais tias ib tug transformation yog ib tug dilation?
Ib qho kev piav qhia ntawm qhov dilation suav nrog qhov ntsuas qhov ntsuas (lossis qhov piv) thiab qhov nruab nrab ntawm qhov dilation. Qhov chaw ntawm dilation yog ib qho chaw ruaj khov hauv lub dav hlau. Yog tias qhov ntsuas qhov ntsuas ntau dua 1, daim duab yog qhov loj (qhov ncab). Yog tias qhov ntsuas qhov ntsuas nyob nruab nrab ntawm 0 thiab 1, daim duab yog qhov txo qis (qhov qis)
Yuav ua li cas koj thiaj paub yog hais tias ib tug function tsis yog ib tug function?
Kev txiav txim siab seb qhov kev sib raug zoo yog qhov ua haujlwm ntawm daim duab yog qhov yooj yim los ntawm kev siv cov kab ntsug. Yog tias txoj kab ntsug hla qhov kev sib raug zoo ntawm daim duab ib zaug hauv txhua qhov chaw, qhov kev sib raug zoo yog qhov ua haujlwm. Txawm li cas los xij, yog tias txoj kab ntsug hla qhov kev sib raug ntau dua ib zaug, qhov kev sib raug zoo tsis muaj nuj nqi
Yuav ua li cas yog qhov tshwm sim uas ib tug poj niam dig muag xim uas yuav ib tug txiv neej uas tsis pom kev zoo yuav muaj xim dig muag me nyuam?
Yog tias tus poj niam uas muaj lub zeem muag zoo li no (heterozygous rau qhov muag tsis pom xim) yuav ib tug txiv neej ib txwm muaj (XY), cov xeeb ceem hauv qab no tuaj yeem xav tau hauv F2 tiam: ntawm cov ntxhais, 50% yog ib txwm muaj thiab 50% yog cov neeg nqa khoom rau cov kab mob; ntawm cov tub, 50% yog xim dig muag thiab 50% yog qhov pom kev zoo
Yuav ua li cas yog ib tug piv txwv ntawm ib tug rational naj npawb uas tsis yog ib tug tag nrho?

Yuav ua li cas ib tug geologist yuav qhia tau hais tias ib tug quav yog ib tug syncline thiab anti-line?
Geologic Structures (Part 5) Anticlines yog folds nyob rau hauv uas txhua ib nrab ntawm cov quav dips deb ntawm lub crest. Synclines yog folds nyob rau hauv uas txhua ib nrab ntawm cov quav dips mus rau lub trough ntawm lub quav. Koj tuaj yeem nco qab qhov sib txawv los ntawm kev ceeb toom tias anticlines tsim "A" zoo, thiab synclines tsim hauv qab ntawm "S."
