Siv tau Multiplication Factor . Qhov zoo multiplication factor yog qhov ratio ntawm cov neutrons ua los ntawm fission nyob rau hauv ib neutron tiam mus rau tus naj npawb ntawm neutrons poob los ntawm kev nqus hauv qhov ua ntej neutron tiam. Qhov no tuaj yeem qhia ua lej qhia hauv qab no.
Hauv qhov no, dab tsi yog qhov kev sib npaug?
Kev txhais ntawm multiplication factor .: qhov piv ntawm cov naj npawb ntawm cov neutrons tsim nyob rau hauv ib pawg nuclear rau cov lej ploj uas yuav tsum sib npaug lossis tshaj kev sib koom ua ke rau kev sib txuas sib txuas ua ke. - hu ua reproduction tas mus li, kev yug me nyuam yam.
Tsis tas li ntawd, dab tsi yog qhov kev tsim tawm ntawm neutron hauv nuclear reactor? neutrons nyob rau hauv fission cov tshuaj tiv thaiv… neutrons absorbed yog hu ua kev yug me nyuam . Thaum ntawd yam tshaj kev sib koom ua ke, kev sib txuas lus yuav pib, uas yog lub hauv paus ntawm nuclear - zog reactors thiab lwm yam fission khoom siv.
Ntxiv mus, dab tsi yog neutron reproduction factor?
Tus naj npawb ntawm neutrons tsim nyob rau hauv lub newgeneration yog txiav txim los ntawm lub neutron reproduction factor . Qhov kev yug me nyuam , η, txhais tau tias yog qhov piv ntawm tus lej ceev neutrons ua los ntawm thermal fission tothe tooj. ntawm thermal neutrons absorbed nyob rau hauv cov roj.
K siv tau li cas?
Lub neutron multiplication ntawm ib qho system, Ib qho teeb meem tshwm sim vim tsis muaj qhov tseeb k - siv tau , feem ntau yog siv los ntsuas qhov sib xws ntawm k - siv tau thiab kev nyab xeeb ntawm lub cev kev nyab xeeb hauv kev ntsuas.

Dab tsi yog qhov density dependent limiting factor txhais li cas?
Ceev Yus Tswj yam Lub ceev nyob yam yog yam tseem ceeb uas nws los nyob rau hauv lub me me los yog txoj kev loj hlob ntawm cov pejxeem sib txawv nrog cov pejxeem ceev. Muaj ntau ntau yam ntawm qhov ntom ntom ntawm qhov txwv tsis pub muaj xws li; muaj zaub mov, predation, kab mob, thiab tsiv teb tsaws
Radiation weighting factor yog dab tsi?
Qhov ntsuas hluav taws xob hnyav yog qhov kwv yees ntawm qhov ua tau zoo ntawm ib chav tsev ntawm qhov muab hluav taws xob cuam tshuam rau tus qauv qis-LET. Gy (joule / kg) tuaj yeem siv rau txhua hom hluav taws xob. Gy tsis piav txog cov teebmeem lom ntawm cov hluav taws xob sib txawv
Dab tsi yog txhais los ntawm steric factor?
Kuj hu ua qhov tshwm sim qhov tshwm sim, qhov steric tau txhais tias yog qhov piv ntawm qhov kev sim ntawm tus nqi tas li thiab qhov kwv yees los ntawm kev sib tsoo txoj kev xav. Nws tseem tuaj yeem txhais tau tias yog qhov piv ntawm qhov ua ntej exponential thiab qhov sib tsoo zaus, thiab nws feem ntau tsawg dua kev sib sau
Dab tsi yog scaling nyob rau hauv multiplication?
Yog tias koj tab tom ua tus qauv ntsuas uas loj dua, ces koj yuav muab ntau dua los ntawm qhov ntsuas qhov loj dua 1. Yog tias koj qhov ntsuas qhov ntsuas yog 2, ces koj tus qauv yog ob zaug loj dua li qhov tiag. Nco ntsoov, qhov ntsuas qhov ntsuas nruab nrab ntawm 0 thiab 1 yuav muab cov qauv me me rau koj. Tus lej me dua, tus qauv me dua
Boolean multiplication yog dab tsi?
Hauv lwm lo lus, Boolean kev sib ntxiv sib raug rau qhov kev ua haujlwm ntawm "AND" lub rooj vag, nrog rau kev hloov pauv kev sib cuag: Zoo li "ib txwm" algebra, Boolean algebra siv cov tsiaj ntawv sau rau denotevariables. Piv txwv li, yog tias qhov sib txawv "A" muaj tus nqi ntawm 0, ces qhov sib ntxiv ntawm A muaj tus nqi ntawm 1
