Khw tshuaj deb ntawm zaub mov khaws cia thiab thaj chaw tiv tauj. Tshuaj tau yooj yim tau rau hauv cov zaub mov los yog nchuav rau ntawm cov khoom noj-hu rau yog tias lawv yog khaws cia tsis raug. A cais thaj chaw yuav tsum tau siv rau chemical cia rau ua xyuas kom koj cov zaub mov thiab khoom siv nyob nyab xeeb.
Ua li no, koj yuav khaws cov tshuaj hauv chav ua noj li cas?
Khaws tag nrho khaws cov tshuaj , tshwj xeeb tshaj yog cov kua hluav taws kub, kom deb ntawm tshav kub thiab ncaj qha tshav ntuj.
Cov yuam sij rau kev nyab xeeb tshuaj cia:
- Segregate tag nrho cov tshuaj tsis sib xws rau kev khaws cov tshuaj zoo los ntawm chav kawm txaus ntshai.
- Tsis txhob khaws cov tshuaj alphabetically tshwj tsis yog nyob rau hauv ib pawg ntawm cov tshuaj sib xws.
Kuj Paub, cov tshuaj tua kab mob yuav tsum khaws cia rau qhov twg? Txhua yam tshuaj thiab tshuaj suav nrog xab npum, tshuaj ntxuav tes, tshuaj tua kab mob thiab tshuaj tua kab yuav tsum ua khaws cia deb ntawm cov khoom noj, cov khoom siv, cov khoom siv warewash, thiab cov chaw npaj zaub mov.
Tsis tas li ntawd, vim li cas cov tshuaj yuav tsum tau khaws cia kom raug?
Ib yam khoom phem ua tau tuaj nyob rau hauv ntau hom; feem ntau yog kua ( tshuaj , kua dej thiab lwm yam) Ntim xav tau kom tsim nyog thiaj li ua tau zoo (piv txwv li cov tshuaj uas muab cov pa phem yuav tsum tau khaws cia hauv cov thawv ntim cua kom haum kom tsis txhob muaj pa tawm mus rau saum huab cua).
Cov tshuaj khaws cia zoo li cas?
Txhawm rau khaws cov tshuaj kom zoo, ua raws li hauv qab no;
- Sau tag nrho cov thawv ntim tshuaj.
- Muab qhov chaw cia tshwj xeeb rau txhua yam tshuaj, thiab xyuas kom rov qab los tom qab siv txhua qhov.
- Khaws cov tshuaj lom tsis haum thiab cov tshuaj tsw qab hauv cov khoom cua.
- Khaws cov kua hluav taws xob hauv cov khoom siv hluav taws xob uas tau pom zoo.

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
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
Yuav ua li cas yog vim li cas tus qauv ntawm ib qho enzyme tseem ceeb heev rau nws txoj haujlwm hauv cov khoom muaj sia?
Enzymes ua kom cov tshuaj tiv thaiv uas tshwm sim hauv cov hlwb. Qhov kev ua haujlwm no cuam tshuam ncaj qha rau lawv cov qauv, nrog rau txhua qhov enzyme tau tshwj xeeb zoo li tus ua kom muaj zog rau ib qho tshuaj tiv thaiv. Kev poob ntawm cov qauv ua rau poob haujlwm. - Kub, pH, thiab kev tswj cov molecules tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov enzymes
Vim li cas nws tseem ceeb heev uas yuav tsum xav txog ntau yam thaum txiav txim siab cov hauv paus hniav ntawm cov kab zauv polynomial?
Piv txwv li, tus naj npawb ntawm lub sij hawm ib tug muab polynomial sib npaug muaj ib lub hauv paus ntawm ib tug muab point yog lub multiplicity ntawm lub hauv paus. Qhov kev xav ntawm ntau qhov tseem ceeb yog qhov tseem ceeb kom suav tau kom raug yam tsis muaj kev qhia tshwj xeeb (piv txwv li, ob lub hauv paus suav ob zaug). Li no cov lus qhia, ' suav nrog ntau ntau'
Vim li cas nws tseem ceeb kom nkag siab txog tus cwj pwm ntawm cov pa roj?
Txoj kev kawm ntawm cov pa roj tso cai rau peb kom nkag siab txog tus cwj pwm ntawm qhov teeb meem ntawm nws qhov yooj yim tshaj plaws: cov khoom ntawm tus kheej, ua haujlwm ntawm nws tus kheej, yuav luag tsis yooj yim los ntawm kev sib cuam tshuam thiab kev cuam tshuam ntawm ib leeg
