LADP-1 Gwajin Gwaji na CW NMR - Babban Samfuri

Short Bayani:


Bayanin Samfura

Alamar samfur

Maganganun maganadisu na nukiliya (NMR) wani nau'ine ne na sauyawar yanayin yanayi wanda ya haifar da tasirin electromagnetic a filin maganadisu na yau da kullun. Tunda aka gudanar da waɗannan karatun a cikin 1946, hanyoyin da dabarun haɓakar maganadisu na nukiliya (NMR) an bunƙasa cikin sauri kuma ana amfani dasu ko'ina saboda zasu iya zurfafawa cikin abu ba tare da lalata samfurin ba, kuma suna da fa'idodi na saurin, daidaito da girma ƙuduri A zamanin yau, sun shiga daga ilimin lissafi zuwa ilmin kimiyyar halittu, ilimin halittu, geology, jiyya, kayan aiki da sauran fannoni, suna taka rawa a cikin binciken kimiyya da samarwa.

Wani yanki na zabi: Mitar mita, sashin shirya kai oscilloscope

Wannan tsarin gwajin na ci gaba da juyawar tasirin maganadisu na nukiliya (CW-NMR) yana kunshe da babban maganadisu mai kama da juna da kuma babban naurar inji. Ana amfani da maganadisu madawwami don samar da magnetic magudi na farko wanda aka daidaita shi ta hanyar daidaitaccen filin electromagnetic, wanda aka samar da shi ta hanyar dunƙule biyu, don ba da damar daidaita daidaituwa zuwa jimlar maganadisu da kuma rama canje-canje na magnetic sanadiyyar canjin yanayi.

Saboda ƙananan magnetizing na yanzu ana buƙata don ƙananan electromagnetic filin, matsalar dumama tsarin tana raguwa. Don haka, ana iya sarrafa tsarin ci gaba har tsawon awanni. Yana da kayan aikin gwaji don ingantattun dakunan gwaje-gwaje na kimiyyar lissafi.
