Cov ua ntej siv hauv SI yog los ntawm Latin thiab Greek, thiab lawv xa mus rau cov lej uas cov ntsiab lus sawv cev. SI yog siv nyob rau hauv ntau qhov chaw thoob ntiaj teb, yog li peb siv ntawm nws tso cai rau cov kws tshawb fawb los ntawm cov cheeb tsam sib txawv siv ib tug qauv nyob rau hauv kev sib txuas lus scientific cov ntaub ntawv uas tsis muaj cov lus tsis meej pem.
Tom qab ntawd, vim li cas cov kws tshawb fawb siv International System of Units SI)?
Cov kws tshawb fawb siv ib tug sib koom qhov system rau kev ceeb toom ntsuas hu ua International System of Units ( SI ). Peb siv Cov kev ntsuas kev ntsuas feem ntau vim kev tshawb fawb muaj ntau qhov kev rov ua dua (piv txwv li, rov ua dua) kom paub meej cov txiaj ntsig.
Ib tug kuj yuav nug, vim li cas SI units thiaj li muaj txiaj ntsig zoo rau lub ntsuas ntsuas? Cov prefixes txuas rau metric units nqa tib lub ntsiab lus rau txhua lub hauv paus units . Cov metric system yog raws li lub hwj chim ntawm kaum, uas yog yooj yim vim: Vim metric units yog kaum tsib -raws li, lawv tau yooj yim hloov dua siab tshiab los ntawm tsiv lub kaum tsib taw tes.
Tib neeg kuj nug, vim li cas SI unit tau qhia?
Cov SI tau tsim nyob rau xyoo 1960 los ntawm 11th General Conference on Weights and Measures (CGPM, Conférence Générale des Poids et Mesures). CGPM yog txoj cai thoob ntiaj teb uas ua kom muaj kev tshaj tawm dav dav SI thiab hloov cov SI raws li qhov tsim nyog los xav txog qhov kev nce qib tshiab hauv kev tshawb fawb thiab thev naus laus zis.
Lub ntsiab lus ntawm SI unit yog dab tsi?
International System ntawm Metric Units S. I . yog ib luv luv ntawm Système Internationale lossis International System: peb qhov kev ntsuas ntsuas. Nws yog ib tug txheej txheem thoob ntiaj teb, muab ib hom lus ntawm haiv neeg thiab ntawm txawv ceg ntawm science thiab technology.

Vim li cas peb thiaj siv txoj kab ntsug?
Kev ntsuas kab ntsug tuaj yeem siv los txiav txim siab seb daim duab sawv cev li cas. Yog tias peb tuaj yeem kos ib kab ntsug uas cuam tshuam ib daim duab ntau dua ib zaug, ces daim duab tsis txhais tau tias muaj nuj nqi vim tias ib qho kev ua haujlwm tsuas muaj ib qho txiaj ntsig rau txhua tus nqi nkag
Vim li cas peb thiaj li hais txog kev txwv tsis pub muaj kev hais tawm thiab thaum twg peb yuav hais cov kev txwv?
Peb hais txog kev txwv vim nws yuav ua rau qhov sib npaug tsis tau txhais hauv qee qhov txiaj ntsig ntawm x. Qhov kev txwv ntau tshaj plaws rau cov lus qhia muaj nuj nqis yog N / 0. Qhov no txhais tau tias txhua tus lej muab faib los ntawm xoom tsis tau txhais. Piv txwv li, rau txoj haujlwm f(x) = 6/x², thaum koj hloov x = 0, nws yuav ua rau 6/0 uas tsis tau txhais
Vim li cas peb thiaj siv cov lej tseem ceeb hauv chemistry?
Cov lej tseem ceeb (tseem hu ua tus lej tseem ceeb) yog ib feem tseem ceeb ntawm kev suav lej tshawb fawb thiab lej, thiab cuam tshuam nrog qhov raug thiab raug ntawm cov lej. Nws yog ib qho tseem ceeb rau kev kwv yees qhov tsis paub tseeb ntawm qhov kawg tshwm sim, thiab qhov no yog qhov tseem ceeb ntawm cov duab los ua qhov tseem ceeb heev
Vim li cas nws thiaj li hais tias lub Orthocenter ntawm daim duab peb sab obtuse yuav tsum nyob rau sab nraud ntawm daim duab peb sab?
Nws hloov tawm tias tag nrho peb qhov siab ib txwm sib tshuam ntawm tib lub ntsiab lus - lub npe hu ua orthocenter ntawm daim duab peb sab. Lub orthocenter tsis yog ib txwm nyob hauv daim duab peb sab. Yog tias daim duab peb sab yog obtuse, nws yuav nyob sab nraud. Txhawm rau ua kom qhov no tshwm sim cov kab qhov siab yuav tsum tau txuas ntxiv kom lawv hla
Vim li cas peb thiaj siv qhov khoob hauv spectrophotometer?
Ib tug dawb paug cuvette yog siv los calibrate thespectrophotometer nyeem ntawv: lawv sau cov ntsiab lus teb ntawm ib puag ncig-strument-sample system. Nws yog analogous rau "zeroing" ib teev ua ntej hnyav. Runninga blank tso cai rau koj sau cov kev cuam tshuam ntawm cov cuab yeej tshwj xeeb ntawm koj cov ntawv nyeem
