Lub plhaub no pab txav cua sov los ntawm lub hauv paus ntawm lub hnub qub mus rau qhov chaw ntawm lub hnub qub qhov twg lub zog nyob rau hauv daim ntawv ntawm lub teeb thiab tshav kub yog tso rau hauv qhov chaw. Cov lub hnub qub Lub hom phiaj tseem ceeb hauv lub neej yog kom ua tiav kev ruaj ntseg, lossis kev sib npaug . Lub sij hawm kev sib npaug tsis tau txhais hais tias tsis muaj kev hloov hauv lub hnub qub.
Yog li ntawd, vim li cas qhov sib npaug tseem ceeb rau lub hnub qub?
Equilibrium yog tseem ceeb rau a hnub qub kom ruaj khov. Yog ib hnub qub yog at kev sib npaug , tsis muaj qhov hloov pauv tag nrho hauv cov hnub qub . Rau ib hnub qub kom ua tiav kev sib npaug , gas siab thawb tawm ntawm lub hnub qub 's center yog sib npaug nrog lub ntiajteb txawj nqus rub atoms ntawm qhov chaw.
Kuj Paub, lub hom phiaj ntawm lub hnub qub yog dab tsi? A hnub qub yog lub pob loj loj ntawm cov roj kub, feem ntau yog hydrogen thiab helium. Qhov kub yog siab heev nyob rau hauv nws cov tub ntxhais uas nuclear fusion tshwm sim, ua zog. Lub siab sab nraud ntawm cov pa rhuab los ntawm fusion yog sib npaug los ntawm sab hauv rub ntawm lub ntiajteb txawj nqus, tawm hauv hnub qub hauv hydrostatic equilibrium.
Ntxiv rau qhov no, vim li cas hydrostatic equilibrium tseem ceeb?
A hydrostatic tshuav nyiaj li cas yog ib qho tshwj xeeb tshuav nyiaj li cas rau ntsuas cov khoom hauv dej. Hydrostatic tshuav nyiaj li cas tso cai rau kev tshawb pom ntawm lawv cov gravities tshwj xeeb. Qhov no kev sib npaug siv tau nruj me ntsis thaum cov kua dej zoo tshaj plaws nyob rau hauv cov kab rov tav laminar ntws tsis tu ncua, thiab thaum twg cov kua dej nyob ntawm so lossis ntsug ntsug ntawm qhov ceev tsis tu ncua.
Thaum lub hnub qub nyob hauv hydrostatic equilibrium?
Lub ntiajteb txawj nqus ntau dua compresses cov pa roj, ua rau nws denser thiab kub dua, yog li lub siab sab nraud nce. Nyob rau hauv tej txheej txheej ntawm a hnub qub , muaj qhov sib npaug ntawm cov thermal siab (sab nraud) thiab qhov hnyav ntawm cov khoom saum toj no nias downward (sab hauv). Qhov nyiaj tshuav no hu ua hydrostatic equilibrium.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Vim li cas thiaj tswj tau qhov sib npaug tseem ceeb hauv cov hnub qub?
Lub zog sab hauv ntawm lub ntiajteb txawj nqus yog sib npaug los ntawm sab nraud quab yuam kom lub hnub qub ruaj khov. Lub hnub qub lub zog, los ntawm cov tshuaj tiv thaiv nuclear, yog tsim nyob rau hauv nws cov tub ntxhais ua tsaug rau lub siab kub ntawm cov tub ntxhais nws tus kheej. Nyob rau hauv lem, lub zog tsim los ntawm cov tshuaj tiv thaiv nuclear pab kom sib npaug ntawm sab hauv rub ntawm lub ntiajteb txawj nqus
Dab tsi yog qhov tseem ceeb ntawm cov coefficients hauv kev sib npaug sib npaug?
Coefficients yog ib qho tseem ceeb los ua pov thawj txoj cai ntawm kev txuag ntawm huab hwm coj. Cov coefficients nyob rau hauv ib qho kev sib npaug ntawm cov tshuaj sib npaug qhia cov txheeb ze ntawm moles ofreactants thiab cov khoom. Los ntawm cov ntaub ntawv no, lub Cheebtsam ntawm reactants thiab cov khoom yuav raug xam. Koj tuaj yeem txiav txim seb tus lej ntawm moles ntawm cov khoom
Nws puas yuav ua rau pom qhov sib npaug ntawm kab sib npaug mus rau ib kab thiab los ntawm ib qho taw tes ntawm kab?
Qhov sib npaug ntawm ib kab uas yog parallel lossis perpendicular rau ib kab? Cov lus teb tau: Cov nqes hav ntawm cov kab sib npaug sib npaug. Hloov txoj kab nqes paub thiab cov kev sib koom ua ke ntawm ib qho taw tes ntawm lwm txoj kab rau hauv daim ntawv point-slope kom pom qhov sib npaug ntawm kab sib npaug
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
