Hom kev sim . yuam kev feem ntau muab faib ua peb pawg: systematic yuam kev , random yuam kev , thiab blunders. Systematic yuam kev yog vim raug txheeb xyuas qhov ua rau thiab tuaj yeem, hauv paus ntsiab lus, raug tshem tawm.
Ib yam li ib tug yuav nug, dab tsi yog qhov kev sim ua yuam kev zoo?
Engineers kuj yuav tsum tau ceev faj; Txawm hais tias qee qhov kev ntsuas engineering tau ua nrog qhov tseeb zoo (xws li, qhov ceev ntawm lub teeb yog 299, 792, 458 1 m / sec.), rau feem ntau yuam kev tsawg dua 1 feem pua yog xam zoo , thiab rau ob peb tug yuav tsum siv advanced kev sim tsim thiab tsom xam cov txheej txheem kom tau ib yam
Tsis tas li ntawd, peb hom kev ua yuam kev yog dab tsi? Muaj peb hom kev ua yuam kev : syntax yuam kev, logical yuam kev thiab run-time yuam kev. (Logical yuam kev kuj hu ua semantic yuam kev).
Ib yam li ntawd, tib neeg nug, hom kev ntsuas qhov yuam kev yog dab tsi?
Hom ntawm yuam kev hauv Kev ntsuas Qhov system. Feem ntau yuam kev raug cais ua peb hom : systematic yuam kev , random yuam kev thiab blunders. Tag nrho yuam kev yog tshwm sim los ntawm kev ua yuam kev hauv kev siv cov cuab yeej lossis ntsuas, suav ntsuas thiab sau cov ntaub ntawv tshwm sim.
Lab yuam kev yog dab tsi?
Kev tshawb fawb labs feem ntau hais kom koj sib piv koj cov txiaj ntsig tawm tsam qhov kev xav lossis paub qhov tseem ceeb. Qhov no yuav pab koj ntsuas koj cov txiaj ntsig thiab muab piv rau lwm tus neeg cov txiaj ntsig. Qhov sib txawv ntawm koj cov txiaj ntsig thiab cov txiaj ntsig xav tau lossis theoretical hu ua yuam kev.

Dab tsi yog 2 hom kev quab yuam ntawm kev nyiam?
Cov rog no tuaj yeem muab faib ua 2 hom: Intramolecular rog: Intramolecular quab yuam ntawm attraction yog lub zog ntawm attraction uas khaws ib lub molecule ua ke. Intermolecular rog: Intermolecular rog yog lub zog ntawm kev nyiam lossis kev tawm tsam uas ua haujlwm ntawm cov khoom nyob sib ze (atoms, molecules lossis ions)
Dab tsi yog qhov kev twv ua yuam kev hauv kev txheeb cais?
Qhov kev twv ua yuam kev yog qhov ua tsis tiav ntawm qee qhov kev xav tau tshwm sim. Kev twv ua ntej yuam kev, nyob rau hauv cov ntaub ntawv ntawd, tej zaum yuav raug muab tus nqi tsis zoo thiab kwv yees qhov txiaj ntsig zoo, qhov twg AI yuav raug tsim los sim ua kom nws cov qhab nia siab tshaj plaws
Dab tsi yog qhov kev ua yuam kev hauv kev sim nrog cov hluav taws xob tam sim no?
Cov peev txheej ntawm kev ua yuam kev suav nrog cov cuab yeej, ib puag ncig, txheej txheem, thiab tib neeg. Tag nrho cov kev ua yuam kev no tuaj yeem ua tsis tau lossis ua haujlwm nyob ntawm seb lawv cuam tshuam li cas. Instrumental yuam kev tshwm sim thaum cov cuab yeej siv tsis raug, xws li qhov sib npaug uas tsis ua haujlwm (SF Fig

Cov piv txwv ntawm kev sim ua yuam kev yog dab tsi?
Melting point tshwm sim los ntawm ib pawg ntawm kev sim siab yog ib qho piv txwv ntawm qhov kawg. Blunders ( yuam kev). Tib neeg yuam kev. Kev soj ntsuam qhov system yuav ua rau yuam kev. Kev ua yuam kev vim muaj kev cuam tshuam sab nraud. Tsis yog txhua qhov kev ntsuas muaj qhov ntsuas tau zoo. Qauv
