Ib yam li ntawd, qhov kev xeem zoo hauv chemistry yog dab tsi?
Hauv chemistry , kev soj ntsuam zoo yog kev txiav txim siab ntawm tshuaj muaj pes tsawg leeg ntawm tus qauv. Kev soj ntsuam zoo tuaj yeem qhia rau koj seb puas yog atom, ion, pawg ua haujlwm, lossis cov khoom sib txuas tam sim no lossis tsis nyob hauv cov qauv, tab sis nws tsis muab cov ntaub ntawv hais txog nws qhov ntau.
Dhau li saum toj no, qhov txawv ntawm qhov kev xeem zoo thiab ntau npaum li cas? Kev txhais ntawm qualitative thiab quantitative tsom xam Qhov zoo Cov ntaub ntawv tsom xam yog raws li kev faib tawm ntawm cov khoom (cov neeg koom nrog) raws li cov khoom thiab cov yam ntxwv whereas kom muaj nuj nqis tsom xam yog nyob ntawm kev faib cov ntaub ntawv raws li kev suav cov nqi.
Ib tug kuj yuav nug, dab tsi yog qhov piv txwv ntawm kev soj ntsuam zoo?
Piv txwv ntawm Qualitative Analysis Qualitative analysis thiab cov kev tshawb fawb feem ntau suav nrog: Cov pab pawg tsom. Daim ntawv teev npe. Qhib cov lus nug thiab kev tshawb fawb. Kev xam phaj tsis tsim nyog.
Koj txhais li cas los ntawm cov ntaub ntawv zoo?
Cov ntaub ntawv zoo yog txhais raws li tus cov ntaub ntawv uas approximates thiab characterizes. Qhov no cov ntaub ntawv hom tsis yog tus lej hauv qhov xwm txheej. Hom no cov ntaub ntawv yog sau los ntawm cov kev soj ntsuam, kev sib tham ib-rau-ib, ua cov pab pawg tsom xam thiab cov kev zoo sib xws. Cov ntaub ntawv zoo hauv kev txheeb cais tseem hu ua categorical cov ntaub ntawv.

Dab tsi yog thaj chaw ntawm pej xeem kev hloov pauv thiab vim li cas nws thiaj li muaj txiaj ntsig thaum kawm txog pej xeem?
Population dynamics yog ceg ntawm lub neej sciences uas kawm txog qhov loj thiab hnub nyoog muaj pes tsawg leeg ntawm cov pejxeem raws li dynamical systems, thiab cov txheej txheem lom thiab ib puag ncig tsav lawv (xws li yug thiab tuag tus nqi, thiab los ntawm kev nkag teb chaws thiab emigration)
Nws txhais li cas thaum kev sib raug zoo ntawm kev sib raug zoo ua kev cuam tshuam?

Kev nyuaj siab qhov chaw khov kho yog cov cuab yeej sib koom ua ke pom hauv cov kev daws teeb meem uas tshwm sim los ntawm kev qhia txog cov kuab tshuaj molecules rau cov kuab tshuaj. Cov ntsiab lus khov ntawm cov kev daws yog tag nrho qis dua li cov kuab tshuaj ntshiab thiab yog ncaj qha proportional rau molality ntawm cov kuab tshuaj
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
