Infinite Solutions . Thawj yog thaum peb muaj dab tsi hu ua kev daws teeb meem tsis kawg . Qhov no tshwm sim thaum txhua tus lej kev daws teeb meem . Qhov xwm txheej no txhais tau tias tsis muaj leej twg daws . Cov kev sib npaug 2 x + 3 = x + x + 3 yog ib qho piv txwv kev sib npaug uas muaj tsis kawg tus lej ntawm kev daws teeb meem.
Khaws qhov no hauv kev xav, dab tsi yog lub cim rau kev daws teeb meem tsis kawg?
Qee zaum peb siv cov cim ∞, uas txhais tau tias tsis kawg , sawv cev kev daws teeb meem tsis kawg.
Qhov thib ob, dab tsi yog 0x hauv algebra? Thaum peb muab ntau tus lej, txhua qhov sib txawv, ib qho kev qhia, ib qho kev sib npaug nrog xoom qhov tshwm sim yog xoom. Yog li, thaum peb muab 0 los ntawm x thiab sau nws li 0x ib , nws ua rau tsis muaj kev nkag siab vim thaum kawg cov lus teb yog xoom.
Ib yam li ntawd, puas yog 0 0 infinite lossis tsis muaj kev daws teeb meem?
Ben Mai · Becca M. Rau cov lus teb kom muaj ib qho kev daws teeb meem tsis kawg , ob qhov sib npaug thaum koj daws yuav sib npaug 0=0 . Ntawm no yog ib qho teeb meem uas muaj ib qho tsis kawg tus lej ntawm kev daws teeb meem . Yog koj daws qhov no koj cov lus teb yuav yog 0=0 qhov no txhais tau tias qhov teeb meem muaj tsis kawg tus lej ntawm kev daws teeb meem.
Dab tsi yog infinitely ntau txoj kev daws teeb meem?
Ib qho system ntawm kab zauv sib npaug tuaj yeem tsis muaj daws , ib tug tshwj xeeb daws los yog infinitely ntau txoj kev daws teeb meem . Ib qho system muaj infinitely ntau txoj kev daws teeb meem thaum nws zoo ib yam thiab tus naj npawb ntawm qhov sib txawv yog ntau tshaj li tus naj npawb ntawm cov kab nonzero hauv rref ntawm matrix.

Dab tsi yog cov xim muaj nyob rau hauv daim ntawv qhia kev phom sij rau kev noj qab haus huv hauv NFPA 704?
NFPA 704 pob zeb diamond kos npe siv los tso saib cov ntaub ntawv no muaj plaub ntu xim: xiav, liab, daj, thiab dawb. Txhua ntu yog siv los txheeb xyuas ib pawg sib txawv ntawm qhov muaj peev xwm txaus ntshai. Ntu xiav ntawm NFPA xim code cim qhia txog kev phom sij rau kev noj qab haus huv
Dab tsi xim yog phenol liab nyob rau hauv ib qho kev daws teeb meem?
Phenol liab yog cov kua qaub-puag qhia. Nws yog tsim los ntawm condensing ob moles ntawm phenol nrog ib tug mole ntawm o-sulfobenzoic acid anhydride. Phenol Liab yog siv los ua pH qhia hauv daim ntawv thov kab lis kev cai ntawm tes. Kev daws ntawm phenol liab yuav muaj xim daj ntawm pH ntawm 6.4 lossis qis dua thiab xim liab ntawm pH
Dab tsi yog qhov concentration ntawm hydronium ions nyob rau hauv ib qho kev daws teeb meem?
Cov dej ntshiab yog suav tias yog nruab nrab thiab qhov concentration ntawm hydronium ion yog 1.0 x 10-7 mol / L uas yog sib npaug rau hydroxide ion concentration
Dab tsi yog cov ions nyob rau hauv siab tshaj plaws concentration nyob rau hauv lub extracellular kua?
Cov tshuaj no nyob rau hauv cov kua dej extracellular thiab intracellular. Nyob rau hauv cov kua dej extracellular, cov cation loj yog sodium thiab cov anion loj yog chloride. Qhov loj cation nyob rau hauv cov kua dej intracellular yog poov tshuaj. Cov electrolytes no ua lub luag haujlwm tseem ceeb hauv kev tswj hwm homeostasis
Nyob rau hauv dab tsi organelle yog pyruvate oxidation nqa tawm nyob rau hauv ib lub cell?
Pyruvate oxidation cov kauj ruam Pyruvate yog tsim los ntawm glycolysis nyob rau hauv lub cytoplasm, tab sis pyruvate oxidation tshwm sim nyob rau hauv lub mitochondrial matrix (hauv eukaryotes). Yog li, ua ntej cov tshuaj tiv thaiv tuaj yeem pib, pyruvate yuav tsum nkag mus rau mitochondrion, hla nws daim nyias nyias thiab tuaj txog ntawm matrix
