1 Teb. Ernest Z. Ob lub ntsiab tseem ceeb uas txiav txim siab txog kev ruaj ntseg nuclear yog cov neutron/proton ratio thiab tag nrho cov nucleons nyob rau hauv lub nucleus . Qhov tseem ceeb ntawm kev txiav txim siab seb a nucleus yog ruaj khov yog qhov piv ntawm neutron rau proton.
Cov lus nug tseem yog, ua li cas neutrons cuam tshuam rau kev ruaj ntseg nuclear?
Tom qab ib qho me me, lub zog muaj zog tsis muaj peev xwm rau tuav lub nucleus ua ke. Ntxiv ntxiv neutrons nce qhov chaw nruab nrab ntawm cov protons. Qhov no txo lawv cov repulsions tab sis, yog tias muaj yog ntau dhau lawm neutrons , cov nucleus yog dua tawm ntawm qhov sib npaug thiab lwj.
Qhov thib ob, dab tsi ua rau muaj kev tsis sib haum xeeb nuclear? Raws li tus naj npawb ntawm protons nyob rau hauv lub nucleus nce, tus naj npawb ntawm neutrons xav tau rau ib tug ruaj khov nucleus nce ntau dua sai. Muaj ntau cov protons (los yog tsawg heev neutrons) nyob rau hauv lub nucleus ua rau muaj kev tsis sib haum xeeb ntawm cov rog, uas ua rau nuclear instability.
Teb:
- xov tooj cua.
- ruaj khov.
- xov tooj cua.
- ruaj khov.
Yog li ntawd, dab tsi yog qhov tsis ruaj khov tshaj plaws?
Francium
Yuav ua li cas txiav txim lub npe ntawm ib lub caij?
Cov npe ntawm cov khoom raug txiav txim siab los ntawm lawv txoj haujlwm ntawm lub Lub Sijhawm Sijhawm . Nyob rau hauv niaj hnub Lub Sijhawm Sijhawm , cov ntsiab lus tau teev nyob rau hauv kev txiav txim los ntawm kev nce atomic tooj. Tus lej atomic yog tus tus naj npawb ntawm protons nyob rau hauv lub nucleus ntawm ib tug atom ntawm ib lub caij.

Yuav ua li cas koj xam tus qauv sib txawv ntawm PMP?
Cov mis siv nyob rau hauv PMBOK rau tus qauv sib txawv yog yooj yim. Nws tsuas yog (P-O) / 6. Qhov ntawd yog qhov pessimistic kev ua ub no kwv yees rho tawm qhov kev kwv yees qhov kev xav tau muab faib los ntawm rau. Qhov teeb meem yog qhov no nyob rau hauv tsis muaj txoj kev zoo los yog daim ntawv tsim ib qho kev ntsuas ntawm tus qauv deviation
Yuav ua li cas koj xam qhov ncig ntawm lub ntiaj teb ntawm nws latitude?
Circumference ntawm lub voj voog yog sib npaug rau 2 π r qhov twg r yog nws lub vojvoog. Nyob rau hauv lub ntiaj teb no, lub circumference ntawm tus kheej ntawm ib tug muab latitude yog 2πr(cos θ) qhov twg θ yog lub latitude thiab r yog lub vojvoog ntawm lub ntiaj teb ntawm kab zauv
Yuav ua li cas koj xam qhov zaus ntawm zaus thiab feem pua?
Ua li no, faib cov zaus los ntawm tag nrho cov txiaj ntsig thiab muab faib los ntawm 100. Hauv qhov no, qhov zaus ntawm thawj kab yog 1 thiab tag nrho cov txiaj ntsig yog 10. Qhov feem pua yog tom qab ntawd yog 10.0. Cov kab kawg yog qhov feem pua Cumulative
Yuav ua li cas koj xam lub sij hawm nws yuav siv sij hawm mus ncig teb chaws?
Kwv yees seb koj yuav mus sai npaum li cas ntawm koj qhov kev mus ncig. Tom qab ntawd, faib koj qhov kev ncua deb ntawm koj qhov nrawm. Qhov no yuav muab rau koj anestimation ntawm koj lub sijhawm mus ncig. Piv txwv li, yog tias koj mus ncig yog 240 mais thiab koj yuav tsav 40 mais ib teev, koj lub sijhawm yuav yog 240/40 = 6hours
Yuav ua li cas koj xam lub sij hawm nws yuav siv ib yam khoom los poob?
Ntsuas qhov deb ntawm qhov khoom yuav poob hauv ko taw nrog tus pas ntsuas lossis ntsuas daim kab xev. Faib qhov kev ncua deb los ntawm 16. Piv txwv li, yog tias cov khoom yuav poob 128 ko taw, faib 128 los ntawm 16 kom tau 8. Xam cov square root ntawm cov kauj ruam 2 los nrhiav lub sij hawm nws yuav siv cov khoom poob hauv vib nas this
