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.
