Cov piv txwv yog feem ntawm cov qauv uas yog kev vam meej, yog li ntawd. (1) Rau loj, muaj kwv yees li ib txwm faib.
Nyob rau hauv no hais txog, dab tsi yog lub ntsiab lus ntawm ib tug piv txwv piv txwv nyob rau hauv kev txheeb cais?
Ib haiv neeg kev faib ua feem yog cov kev faib ua feem ntawm cov tib neeg nyob rau hauv ib tug pej xeem sib koom ib yam zoo, denoted p. Cov piv txwv yog cov kev faib ua feem ntawm cov tib neeg hauv a qauv sib qhia ib yam zoo, denoted ˆp. Cov Qauv Kev faib tawm ntawm p. Nco tseg.
Ib tug kuj yuav nug, qhov txawv ntawm tus qauv piv txwv thiab cov pejxeem feem pua? Yog li ntawd, nws muaj cov txheej txheem ntawm qhov ua tau, qhov kev faib tawm qhov tshwm sim, tus nqi xav tau lossis txhais tau tias, qhov sib txawv, thiab tus qauv sib txawv. Ntawd yog, qhov nruab nrab lossis qhov xav tau ntawm tus nqi piv txwv yog tib yam li cov pejxeem proportions . Nco ntsoov tias qhov no tsis yog nyob ntawm qhov qauv qhov loj los yog qhov pej xeem qhov loj.
Tom qab ntawd, lo lus nug yog, lub hom phiaj ntawm cov qauv piv txwv yog dab tsi?
lub hom phiaj ntawm piv txwv . thaum peb xav tau cov ntaub ntawv ntawm cov pej xeem kev faib ua feem ntawm kev ua tiav, p^ yog siv los tshawb xyuas qhov tsis paub tsis pom p.
Qhov txawv ntawm qhov piv txwv piv txwv thiab piv txwv piv txwv yog dab tsi?
A piv txwv yog tus nqi nruab nrab ntawm a qauv thaum lub piv txwv yog tus nqi ntawm cov qauv uas qhia ib qho kev sib raug zoo rau nws tag nrho. Lawv tuaj yeem siv tau raws li kev kwv yees ntawm cov pejxeem uas lawv tau kuaj los ntawm lawv tsuas yog qhia peb me ntsis txawv cov ntaub ntawv.
Pom zoo:
Dab tsi yog tus lej ntuj thiab tus lej suav nrog piv txwv?
Cov lej ntuj yog tag nrho cov lej 1, 2, 3, 4… Lawv yog cov lej koj feem ntau suav thiab lawv yuav txuas ntxiv mus rau qhov tsis muaj tseeb. Tag nrho cov lej yog txhua tus lej suav nrog 0 piv txwv. 0, 1, 2, 3, 4… Cov zauv suav nrog tag nrho cov lej thiab lawv qhov tsis zoo sib piv xws li.
Tus qauv ntsuas kub thiab siab yog dab tsi Vim li cas tus qauv tsim nyog?
Cov txheej txheem siv cov txheej txheem yog qhov tseem ceeb rau kev qhia txog cov kua dej ntws thiab qhov ntim ntawm cov kua thiab cov pa roj, uas yog nyob ntawm qhov kub thiab txias. STP feem ntau yog siv thaum cov txheej txheem hauv xeev raug siv rau kev suav
Tus qauv qauv yog dab tsi Qhov txawv ntawm tus qauv qauv thiab tus qauv molecular yog dab tsi?
Cov mis mos molecular siv cov cim tshuaj thiab cov ntawv sau npe los qhia cov naj npawb ntawm cov atoms sib txawv hauv cov molecule lossis compound. Ib qho empirical formula muab qhov yooj yim tshaj plaws, tag nrho tus lej piv ntawm atoms hauv ib qho chaw. Cov qauv qauv qhia txog kev sib koom ua ke ntawm cov atoms hauv cov molecule
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
Dab tsi yog qhov txawv ntawm microevolution thiab macroevolution Dab tsi yog qee qhov piv txwv ntawm txhua tus?
Microevolution vs. Macroevolution. Piv txwv ntawm cov kev hloov microevolutionary no yuav suav nrog kev hloov ntawm hom xim lossis loj. Macroevolution, piv txwv li, yog siv los hais txog kev hloov pauv ntawm cov kab mob uas tseem ceeb txaus uas, dhau sijhawm, cov kab mob tshiab yuav raug suav tias yog hom tshiab nkaus xwb
