Acceleration yog Qhov thib ob derivative ntawm kev hloov pauv nrog rau lub sijhawm, Los yog thawj qhov kev sib tw ntawm kev tshaj tawm nrog rau lub sijhawm: Cov txheej txheem thim rov qab: Kev koom ua ke . Ceev ceev yog ib ib feem ntawm acceleration dhau sijhawm. Kev khiav tawm yog ib ib qho ntawm kev nrawm dhau lub sijhawm.
Khaws qhov no rau hauv kev xav, yuav ua li cas thaum koj sib xyaw acceleration?
Los ntawm txhais, kev ceev yog thawj derivative ntawm nrawm nrog rau lub sijhawm. Es tsis txhob sib txawv tshaj tawm mus nrhiav kev ceev , integrate acceleration nrhiav kev nrawm. Qhov no muab peb qhov sib npaug ntawm lub sijhawm. Yog peb xav kev ceev yog tas li, peb tau qhov thiaj li hu ua thawj qhov sib npaug ntawm cov lus tsa suab [1].
Qhov thib ob, yuav ua li cas yog tias koj koom nrog kev hloov chaw? Hauv kev nkag siab ncaj qha rau lej, tus ib qho ntawm hloov chaw nrog rau lub sij hawm tsuas yog ib tug tas mus li ntawm kev koom ua ke . Yog koj xav txog kev tshaj tawm raws li tus nqi hloov ntawm hloov chaw , koj ua tau xav txog hloov chaw raws li tus nqi hloov ntawm ib qho taw tes, yog li ntawd tus ib qho ntawm hloov chaw yuav tsuas yog ib qho point.
Ib yam li ntawd ib tug yuav nug, dab tsi yog qhov tseem ceeb ntawm txoj hauj lwm sawv cev?
Cov ib qho ntawm txoj hauj lwm raws ib lub axis w.r.t lwm axis muab koj thaj chaw mapped los ntawm seem ntawm qhov nkhaus thiab x-axis. Cov ib qho ntawm txoj hauj lwm hais txog lub sij hawm muab rau koj kom muaj nuj nqis nrog units "meters vib nas this".
Tus qauv ntawm acceleration yog dab tsi?
Kev nrawm (a) yog qhov hloov pauv hauv qhov nrawm (Δv) dhau qhov kev hloov pauv hauv lub sijhawm (Δt), sawv cev los ntawm kev sib npaug a = Δv/Δt. Qhov no tso cai rau koj los ntsuas qhov nrawm nrawm npaum li cas hloov pauv hauv meters ib ob squared (m / s^2). Kev nrawm kuj yog ib qho vector kom muaj nuj nqis, yog li nws suav nrog ob qho tib si loj thiab kev coj ua.

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
Vim li cas qhov tseem ceeb ntawm qhov tseem ceeb?
Thaum koj pom tus nqi kiag li hauv qhov teeb meem lossis qhov sib npaug, nws txhais tau hais tias txhua yam nyob hauv tus nqi tiag tiag yog qhov zoo. Cov txiaj ntsig tsis zoo feem ntau siv rau hauv cov teeb meem cuam tshuam nrog kev nyob deb thiab qee zaum siv nrog qhov tsis sib xws. Qhov ntawd yog qhov tseem ceeb uas yuav tsum nco ntsoov nws zoo li qhov deb ntawm xoom
Vim li cas cov nuj nqis tseem ceeb tseem ceeb thaum qhia txog kev ntsuas?
Cov duab tseem ceeb yog qhov tseem ceeb los qhia qhov tseeb ntawm koj cov lus teb. Qhov no yog qhov tseem ceeb hauv kev tshawb fawb thiab engineering vim tias tsis muaj cov cuab yeej ntsuas tuaj yeem ua qhov ntsuas nrog 100% precision. Siv cov nuj nqis tseem ceeb tso cai rau tus kws tshawb fawb paub tias cov lus teb meej npaum li cas, lossis qhov tsis paub meej npaum li cas
Dab tsi ntawm tsab ntawv yog siv los sawv cev rau tus tseem ceeb allele?
Txawm li cas los xij, ntau tus kws tshawb fawb kuj siv cov tsiaj ntawv loj thiab cov tsiaj ntawv me los sawv cev rau cov noob tseem ceeb thiab cov noob qoob loo, feem. Cov tsiaj ntawv no muaj feem cuam tshuam txog qhov zoo hauv nqe lus nug, xws li tsab ntawv B los sawv cev xim av qhov muag ua ib qho tseem ceeb allele
Vim li cas qhov chaw saum npoo rau qhov sib piv ntawm qhov tseem ceeb?
Qhov chaw rau qhov ntim qhov piv yog qhov tseem ceeb vim tias, raws li lub hnub nyoog ntawm tes thiab tsim cov khoom tseem ceeb xws li cov proteins nws loj tuaj. Cell tau loj dua, yog li nws qhov ntim tau loj dua, tab sis hmoov tsis zoo li ntim, thaj chaw ntawm lub xov tooj tsis tau loj dua sai
