Ntxiv Txoj Cai 1: Thaum ob qhov xwm txheej, A thiab B, sib koom ua ke, qhov qhov tshwm sim uas A or B yuav tshwm sim yog qhov sum ntawm cov qhov tshwm sim ntawm txhua qhov xwm txheej. Cov qhov tshwm sim uas A or B yuav tshwm sim yog qhov sum ntawm cov qhov tshwm sim ntawm txhua qhov xwm txheej, rho tawm qhov tshwm sim ntawm qhov sib tshooj. P(A or B) = P(A) + P(B) - P(A thiab B)
Khaws qhov no hauv kev xav, koj puas ntxiv qhov tshwm sim ua ke?
Yog hais tias tag nrho cov xwm txheej tshwm sim (ib qho "thiab lo lus nug") Muab cov tej zaum ua ke . Yog tias tsuas yog ib qho ntawm cov xwm txheej tshwm sim (ib qho "los yog lo lus nug") Ntxiv tus tej zaum ua ke.
Ib tug kuj yuav nug, koj puas tuaj yeem ntxiv qhov muaj peev xwm ywj pheej? Rau nrhiav cov qhov tshwm sim ntawm ob ywj siab xwm txheej uas tshwm sim nyob rau hauv ib ntus, nrhiav cov qhov tshwm sim ntawm txhua qhov xwm txheej tshwm sim sib cais, thiab tom qab ntawd muab faib rau Qhov yuav tshwm sim . Txoj cai sib npaug no yog txhais cov cim hauv qab no.
Ib yam li ntawd, koj ntxiv ob qhov tshwm sim li cas?
Siv cov qauv kev sib npaug tshwj xeeb. Cia li muab cov qhov tshwm sim ntawm thawj qhov xwm txheej los ntawm qhov thib ob. Piv txwv li, yog tias cov qhov tshwm sim ntawm qhov xwm txheej A yog 2/9 thiab qhov tshwm sim ntawm qhov xwm txheej B yog 3/9 ces qhov qhov tshwm sim ntawm ob qhov xwm txheej tshwm sim tib lub sijhawm yog (2/9) * (3/9) = 6/81 = 2/27.
Dab tsi yog txoj cai sib npaug hauv qhov tshwm sim?
Cov Txoj cai muab faib ntawm Qhov yuav tshwm sim txhais tau tias nrhiav tau qhov tshwm sim ntawm kev sib tshuam ntawm ob qhov xwm txheej, ntau ob tug Qhov yuav tshwm sim . Txhawm rau nrhiav kev sib tshuam ntawm ob qhov xwm txheej, txawm tias lawv muaj kev ywj pheej lossis kev vam khom, ntau ob tug Qhov yuav tshwm sim ua ke.

Yuav ua li cas tshwm sim rau tam sim no nyob rau hauv ib tug parallel circuits thaum ntxiv qhov muag teev?
Raws li ntau qhov muag tau ntxiv, qhov tam sim no nce. Raws li ntau resistors ntxiv nyob rau hauv parallel, tag nrho tam sim no lub zog nce. Yog li ntawd, tag nrho cov tsis kam ntawm Circuit Court yuav tsum tau txo. Qhov tam sim no nyob rau hauv txhua lub teeb yog tib yam vim hais tias tag nrho cov qhov muag teev glowed nrog tib brightness
Qhov twg tshwm sim thawj lub teeb nyob ntawm qhov tshwm sim lossis lub teeb ywj pheej?
Lub Teeb-Dependent thiab Lub Teeb-Independent Reactions. Cov tshuaj tiv thaiv lub teeb, lossis cov tshuaj tiv thaiv lub teeb-dependent, yog thawj zaug. Peb hu lawv ob leeg thiab ob lub npe. Nyob rau hauv lub teeb-dependent tshwm sim ntawm photosynthesis, lub zog ntawm lub teeb propels lub electrons los ntawm ib tug photosystem mus rau lub high-zog lub xeev
Tus qauv yuav pab nrhiav qhov tshwm sim ntawm qhov kev tshwm sim sib xyaw li cas?
Lub ntsiab lus ntawm Qhov Muaj Peev Xwm Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej yog ib qho uas muaj ntau tshaj li qhov ua tau. Kev txiav txim siab qhov yuav tshwm sim ntawm qhov kev tshwm sim sib xyaw suav nrog kev nrhiav cov lej ntawm qhov tshwm sim ntawm tus kheej cov xwm txheej thiab, yog tias tsim nyog, tshem tawm qhov muaj feem sib tshooj
Dab tsi yog tsib yam pov thawj uas koj tuaj yeem siv los txiav txim seb puas muaj tshuaj lom neeg tshwm sim?
Qee cov cim qhia txog kev hloov tshuaj lom neeg yog kev hloov xim thiab tsim cov npuas. Lub tsib yam kev hloov ntawm tshuaj lom neeg: xim chage, tsim ntawm precipitate, tsim cov roj, tsw hloov, kub hloov
Yuav ua li cas koj pom qhov tshwm sim ntawm qhov tshwm sim tsawg kawg ib zaug?
Txhawm rau xam qhov tshwm sim ntawm qhov tshwm sim tshwm sim tsawg kawg ib zaug, nws yuav yog qhov sib ntxiv ntawm qhov xwm txheej tsis tshwm sim. Qhov no txhais tau hais tias qhov tshwm sim ntawm qhov tshwm sim yeej tsis tshwm sim thiab qhov tshwm sim ntawm qhov tshwm sim tsawg kawg ib zaug yuav sib npaug, lossis 100% txoj hauv kev
