Abantu abaningi abakwazi ukuhlukanisa phakathi kwerula egreyitha kanye nerula kazibuthe egayidiniumshini wokulinganisa umbono.Namuhla sizokhuluma ngomehluko phakathi kwabo.
Isilinganiso se-grating inzwa eyenziwe ngomgomo wokuphazanyiswa kokukhanya kanye ne-diffraction.Lapho ama-grating amabili anephimbo elifanayo enqwabelene ndawonye, futhi imigqa yenza i-engeli encane ngesikhathi esifanayo, khona-ke ngaphansi kokukhanya kokukhanya okuhambisanayo, ukukhanya okusabalaliswe ngokulinganayo kanye nemigqa emnyama ingabonakala ohlangothini oluqondile lwemigqa.Ibizwa ngokuthi ama-Moiré fringes, ngakho-ke ama-Moiré fringes awumphumela ohlangene wokuphazamiseka kanye nokuphazamiseka kokukhanya.Lapho i-grating inyakaziswa iphimbo elincane, ama-moiré fringe nawo anyakaziswa yi-fringe pitch eyodwa.Ngale ndlela, singakwazi ukukala ububanzi be-moiré fringes lula kakhulu kunobubanzi bemigqa yokugaya.Ukwengeza, njengoba i-moire fringe ngayinye yakhiwe ngeziphambano zemigqa eminingi yokugaya, lapho omunye wemigqa unephutha (isikhala esingalingani noma ukutsheka), lo mugqa oyiphutha kanye nomunye umugqa wokugaya Isikhundla sokuphambana kwemigqa sizoshintsha. .Kodwa-ke, i-moiré fringe yakhiwe ngeziphambanomgwaqo eziningi zolayini wokugaya.Ngakho-ke, ukuguqulwa kwendawo yokuphambana komugqa kunomphumela omncane kakhulu kumphetho we-moiré, ngakho-ke i-moire fringe ingasetshenziselwa ukukhulisa kanye nomphumela omaphakathi.
Isikali kazibuthe inzwa eyenziwe kusetshenziswa isimiso sezigxobo kazibuthe.Isisekelo sayo siwumugqa wensimbi ozibuthe olinganayo.Izigxobo zayo zika-S no-N zihlukaniswe ngokulinganayo emgqeni wensimbi, futhi inhloko yokufunda ifunda izinguquko zezigxobo zika-S no-N ukuze zibalwe.
Isilinganiso sokugaya sithinteka kakhulu izinga lokushisa, futhi indawo yokusetshenziswa evamile ingaphansi kuka-40 degrees Celsius.
Izilinganiso ezivulekile zamagnetic zithinteka kalula ngamasimu kazibuthe, kodwa izikali kazibuthe ezivaliwe azinayo le nkinga, kodwa izindleko ziphezulu.
