The nuclear fusion tsim ib lub nucleus hnyav los ntawm ob lub sib txawv sib txawv. Feem ntau, cov txheej txheem no yog hu ua cov tshuaj tiv thaiv nuclear. Raws li peb txhua tus paub, ob lub sib zog hydrogen atoms feem ntau fused los tsim lub atom loj ntawm helium. Qhov tshuaj tiv thaiv tshuaj no feem ntau piav qhia txog qhov tshwm sim ntawm nuclear fusion.
Qhov twg ob lub nuclei fuse ua ke los tsim ib lub helium nucleus?
Lub deuterium nuclei tuaj yeem sib koom ua ib lub helium nuclei (He-4), lossis lawv tuaj yeem cuam tshuam nrog lwm cov protons los ua lwm cov isotope ntawm helium (He-3). Ob tug He-3 nuclei tuaj yeem fuse ua ib lub nucleus ntawm ib qho tsis ruaj tsis khov beryllium nucleus (Be-6) uas sib cais kom muab He-4 thiab ob protons. Lub zog raug tso tawm ntawm txhua kauj ruam.
Yuav ua li cas thaum ob lub helium fuse ua ke?
Ob lub helium-3 nuclei fuse ua ke, tsim helium-4, ob lub protons (hydrogen-1), thiab lub zog, Helium-3 fuses nrog helium-4, tsim beryllium -7, uas decays thiab ces fuses nrog lwm proton (hydrogen-1) yields ob helium-4 nuclei ntxiv zog.
Nws hu li cas thaum ob lub atom hydrogen fuse tsim helium thiab tso tawm lub zog?
YOG Y FUSION? Fusion yog txheej txheem uas powers lub hnub thiab lub hnub qub. Nws yog cov tshuaj tiv thaiv uas ob lub atoms ntawm hydrogen ua ke, los yog fuse, los ua ib qho atom ntawm helium. Hauv cov txheej txheem qee qhov loj ntawm hydrogen hloov mus rau hauv lub zog.
Yuav ua li cas lub zog tawm thaum ob lub hydrogen nuclei fused los ua ib lub helium nucleus?
Piv txwv li, hauv kev sib xyaw ntawm ob lub nuclei hydrogen los tsim helium, 0.645% ntawm qhov loj yog nqa mus rau hauv daim ntawv ntawm kinetic zog ntawm ib qho alpha particle lossis lwm yam ntaub ntawvntawm lub zog, xws li hluav taws xob hluav taws xob.

Dab tsi hauv lub disc yog tsim los ntawm cov nucleus thiab nyiam dej?
Lub nucleus pulposus yog cov gel zoo li txheej sab hauv ntawm lub disc. Qhov "gel" no yog ua los ntawm dej thiab proteoglycans, thiab nws yog ib feem ntawm cov disc uas feem ntau absorbs thiab cushions koj txav. Yuav ua li cas nyob rau hauv lub disc yog tsim los ntawm lub nucleus?
Los ntawm cov khoom tsim thaum lub sij hawm tsim cov bakelite yog?
Nyob rau hauv rooj plaub ntawm bakelite phenol thiab formaldehyde condense los tsim cov monomer muab H2O raws li cov khoom lag luam. Bakelite tseem hu ua co-polymer. Cov tshuaj tiv thaiv: Phenol reacts nrog formaldehyde los tsim o-Hydroxy methyl phenol.
Thaum lub nucleus siv qhov tsis zoo?
Lub nucleus muaj ob hom subatomic hais, protons thiab neutrons. Cov protons muaj cov nqi hluav taws xob zoo thiab cov neutrons tsis muaj hluav taws xob. Ib hom thib peb ntawm subatomic particle,electrons, txav mus ncig lub nucleus. Cov hluav taws xob muaj hluav taws xob tsis zoo.
Thaum alpha lwj lub nucleus?
Nyob rau hauv alpha lwj, qhia hauv daim duab 3-3, lub nucleus emits ib 4He nucleus, ib qho alpha particle. Alpha decay tshwm sim feem ntau nyob rau hauv loj nuclei uas muaj loj heev proton rau neutron piv. Ib qho alpha particle, nrog nws ob lub protons thiab ob lub neutrons, yog ib qho kev teeb tsa ruaj khov ntawm cov khoom.
Cov pob txha twg fuse tsim cov acetabulum?
Raws li tau hais los saum no, acetabulum yog tsim los ntawm qhov chaw ntawm lub ilium, ischium, thiab pubis . Lub acetabulum yog lub khob zoo li lub qhov (socket) nyob rau sab nraud ntawm lub pelvis, uas articulates nrog lub taub hau ntawm femur taub hau ntawm lub femur A lub duav dislocation yog thaum tus ncej puab (femur) cais los ntawm hip pob txha (pelvis).
