Taw qhia txog Neutron Scattering
Ua tiav cov duab xoo hluav taws xob, thev naus laus zis ua lub luag haujlwm tshwj xeeb hauv kev teeb tsa kev teeb tsa thiab cov duab kos vim lawv tus kheej cov yam ntxwv. Neutrons yog hluav taws xob nruab nrab, nrog lub zog sib zog thiab tsis muaj kev cuam tshuam, kom lawv tuaj yeem tshawb pom lub zog sab hauv cov ntaub ntawv (xws li kev nyuaj siab) ntawm cov tshuaj, thiab kuj yog qhov zoo rau kev tshawb nrhiav hauv cov qauv thiab cov qauv tshwj xeeb ib puag ncig; Cov nyhuv ntawm tsis nce ntxiv nrog qhov nce ntawm atomic tooj, kom lub teeb pom kev los yog cov khoom sib txuas tau zoo dua tuaj yeem daws teeb meem los ntawm neutron tawg lossis duab quag; neutrons muaj qhov rov qab zoo thiab muaj qhov txawv txav kom lawv tuaj yeem qhia tau meej me me qauv sib nqus qauv ntaub ntawv uas lwm txoj kev yooj yim muab. Tus tsim kev tshawb xav txog kev siv hluav taws xob ua kom qis qis hluav taws xob ua kom muaj txoj hauv kev zoo los ua cov txheej txheem ntau qhov kev kwv yees thev naus laus zis, sim tshuaj xyuas qhov tseeb thiab zoo tag nrho txoj kev xav. Neutron scattering thev naus laus zis tuaj yeem tsis tsuas tshawb cov microstructure zoo li qub ntawm cov teeb meem, tab sis kuj tseem siv los kawm qhov kev hloov pauv ntawm lub zog ntawm cov txheej txheem hloov txheej txheem. Yog li no, neutron scattering tau ua lub luag haujlwm tsis zoo nyob rau hauv xoo hluav taws xob hauv thaj teb ntawm physics, chemistry, cov ntaub ntawv, engineering, thiab lwm yam, thiab tau dhau los ua ib qho tseem ceeb ntawm cov khoom siv tshawb fawb thiab tshawb fawb thiab kev loj hlob ntawm cov ntaub ntawv tshiab.
