Ib vector kom muaj nuj nqis muaj a kev taw qhia thiab a qhov loj , thaum ib tug scalar muaj tsuas yog ib qhov loj . Koj tuaj yeem qhia tau yog tias muaj ntau yog ib vector los yog tsis nws muaj a kev taw qhia txuam nrog nws.

Ib yam li ntawd, qhov loj npaum li cas yog qhov taw qhia?

Ntawm qhov tod tes, nrawm, hauv Physics, yuav tsum tau nthuav tawm raws li vector nrog ob qho tib si a qhov loj thiab a kev taw qhia . Piv txwv li, 5 m / s Eastward yog qhov nrawm vim nws qhia koj qhov loj ntawm lub zog, 5 meters ib ob, raws li zoo raws li lub kev taw qhia uas yog Eastward.

Tsis tas li ntawd, qhov loj thiab kev coj ntawm vector yog dab tsi? A vector yog ib yam khoom uas muaj ob qho tib si a qhov loj thiab a kev taw qhia . Ob lub zog thiab nrawm yog nyob rau hauv ib qho tshwj xeeb kev taw qhia . Cov qhov loj ntawm vector yuav qhia tau hais tias lub zog ntawm lub zog los yog speedssociated nrog lub nrawm. Peb qhia cov duab siv boldface li hauv ib lossis b.

Ntxiv mus, koj yuav nrhiav tau qhov loj thiab kev taw qhia ntawm lub nrawm li cas?

Rau xam tus qhov loj ntawm ceev ntawm txhua lub sijhawm, muab qhov sib npaug ntawm qhov sib npaug ntawm lub sijhawm sib txawv thiab tom qab ntawd ntxiv rau qhov pib ceev . Piv txwv li, yog tias koj poob ib pob zeb tawm ntawm acliff, nws ceev nce los ntawm 32 ko taw ib ob, txhua thib ob.

Qhov magnitude motion yog dab tsi?

Hais txog kev loj hlob, qhov loj alludes mus rau qhov tshaj tawm uas ib yam khoom yog voyaging los yog nws loj. Kev tshawb nrhiav ntawm tsab ntawv tsa suab nrug, tshaj tawm, ceev kuj massexpressed raws li qhov ntau - yog cais nyob rau hauv nruab nrab ntawmvectors thiab scalars.

Dab tsi yog qhov txiaj ntsig tseem ceeb ntawm kev taw qhia ntawm tes los ntawm kev sib cuag lub cev ncaj qha?

Kev taw qhia kuj tshwm sim ntawm cov hlwb uas yog kev sib cuag ntawm lub cev. Kev sib cuam tshuam ntawm cov proteins ntawm qhov chaw ntawm cov hlwb tuaj yeem ua rau muaj kev hloov pauv hauv cov cwj pwm ntawm tes. Piv txwv li, cov proteins nyob rau saum npoo ntawm T-cells thiab antigen nthuav tawm cov hlwb sib cuam tshuam los ua kom muaj kev taw qhia hauv T-cells

Dab tsi yog qhov txawv ntawm kev xaiv kev taw qhia thiab kev xaiv cuam tshuam?

Hauv kev xaiv cov kev taw qhia, cov pej xeem cov noob caj noob ces hloov mus rau qhov tshiab phenotype thaum raug kev hloov pauv ib puag ncig. Hauv kev sib txawv lossis kev cuam tshuam kev xaiv, qhov nruab nrab lossis nruab nrab phenotypes feem ntau tsis haum dua li qhov phenotype huab cua thiab tsis zoo li yuav ua rau muaj txiaj ntsig zoo hauv cov pej xeem

Puas muaj teeb meem los ntawm qhov kev taw qhia qhov chaw sib npaug mus txog?

Qhov no ib txwm tshwm sim thaum cov tshuaj tiv thaiv nce mus txog qhov sib npaug. Tsis yog, nws tsis muaj teeb meem los ntawm qhov kev taw qhia qhov chaw sib npaug mus txog. Ob qhov kev sim yuav muab tib txoj haujlwm sib npaug vim tias ob qho kev sim pib nrog stoichiometric cov nyiaj reactants lossis cov khoom lag luam

Puas yog cov lus qhia thesis yog qhov taw qhia?

Tsab ntawv thesis yog dab tsi? Daim ntawv thesis qhia meej meej txog cov ncauj lus uas tau tham, suav nrog cov ntsiab lus uas tau tham hauv daim ntawv, thiab sau rau cov neeg tuaj saib tshwj xeeb.
