Koj ua tau txheeb xyuas ib yam tsis paub los ntawm kev ntsuas nws ceev thiab muab koj cov txiaj ntsig sib piv rau cov npe uas paub qhov ntom . Qhov ntom = loj / ntim. Xav tias koj yuav tsum tau txheeb xyuas ib tsis paub hlau. Koj tuaj yeem txiav txim siab qhov loj ntawm cov hlau ntawm qhov ntsuas.
Hais txog qhov no, vim li cas qhov ceev yog qhov tseem ceeb rau kev txheeb xyuas cov khoom tsis paub?
Qhov ntom tuaj yeem yog pab tau hauv txheeb xyuas cov khoom . Nws kuj yog ib qho cuab yeej yooj yim vim nws muab qhov txuas (lossis hloov pauv hloov pauv) ntawm qhov loj thiab ntim ntawm a yam khoom . Mass thiab ntim yog dav (los yog extrinsic) cov khoom ntawm cov teeb meem - lawv nyob ntawm tus nqi.
Tsis tas li ntawd, qhov ceev tuaj yeem siv los txheeb xyuas cov khoom hauv chav kuaj? Qhov ntom yog ib tug intensive khoom ntawm a yam khoom uas tsis nyob ntawm tus nqi ntawm yam khoom tam sim no. Yog li, ceev tau ua siv rau txheeb xyuas ib tug tsis paub ntshiab yam khoom yog ib daim ntawv teev cov ntaub ntawv siv qhov ntom muaj, thiab tus neeg sim ua tau xaiv ib qho yooj yim npaum li cas yam khoom ua haujlwm nrog thaum ntsuas ceev.
Yog li ntawd, txoj kev twg los txiav txim qhov ceev yog qhov tseeb dua?
Txoj kev no yuav tsum muaj lub thawv ntim dej nrog cov kawm tiav ntim cov cim. Lub khob ntsuas chav ua noj yuav txaus, txawm hais tias lub tog raj kheej kawm tiav siv nyob rau hauv chemistry labs yuav yog qhov tseeb dua. Nyob rau hauv ob qho tib si, lub thawv yuav ntim li ib nrab puv nrog dej thiab cov khoom ces submerged nyob rau hauv cov kua.
Vim li cas thiaj tseem ceeb rau kev txheeb xyuas yam tsis paub?
Kev txheeb xyuas yam tsis paub . Yuav kom daws tau qhov tsis paub, peb feem ntau yuav tsum tau txheeb xyuas tshuaj lom, phom phom residue thiab lwm yam tshuaj . Xim, tsw, thiab tshuaj tiv thaiv rau lwm yam tshuaj yog tshwj xeeb rau tus kheej tshuaj thiab tuaj yeem pab tau txheeb xyuas qhov tseem ceeb tsis paub.

Vim li cas qhov ceev ntawm lub teeb tsis tas li nyob rau hauv tag nrho cov ntaub ntawv siv?
Puas yog vim li cas qhov ceev ntawm lub teeb yog qhov tsis tu ncua nyob rau hauv tag nrho cov ntaub ntawv siv? Qhov tsuas yog qhov uas cuam tshuam qhov ceev ntawm lub teeb yog qhov ntsuas qhov nruab nrab ntawm qhov nruab nrab uas nws txav mus, thiab rau qhov chaw khoob, tus lej no yog 1.000000 thiab muab qhov siab tshaj plaws ntawm lub teeb rau koj
Koj tuaj yeem txheeb xyuas cov khoom tsis paub zoo li cas?
Koj tuaj yeem txheeb xyuas cov khoom tsis paub zoo li cas? Thaum twg koj tuaj yeem ntsib cov tshuaj tsis paub tseeb hauv lub ntiaj teb tiag? Kev sim yooj yim koj tuaj yeem ua tau. Cov txheej txheem chromatographic. Spectroscopic txoj kev. X-ray crystallography (aka X-ray diffraction, lossis XRD) Mass spectrometry
Puas yog tag nrho cov electromagnetic tsis muaj qhov ceev tib yam hauv lub tshuab nqus tsev?
Electromagnetic hluav taws xob yog ib hom hluav taws xob uas feem ntau hu ua lub teeb. Feem ntau hais lus, peb hais tias lub teeb mus rau hauv nthwv dej, thiab tag nrho cov hluav taws xob hluav taws xob hluav taws xob mus rau tib qhov ceev uas yog li 3.0 * 108 meters ib ob los ntawm lub tshuab nqus tsev
Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
