Umgca wesithethi Intshayelelo:
Isithethi se-ARGORY SINILY NOKUFUNDA NGOKUSETYENZISIWEYO. Izithethi ezininzi zinokudityaniswa kwiqela lesithethi kunye nenqanaba elifanayo kunye nesigaba (i-GARY (NORORY), kwaye isithethi sibizwa ngokuba sisithethi se-nolayini. Iinkqubo zeNkqubo yokuLula zihlala zigoba kancinci ukufezekisa i-engile enkulu yokugubungela. Elona candelo liphambili kwintsimi kude neqela kwicandelo elikufutshane. Yenza i-asymmetry ye-asymmetry ye-asymmetry, amanye amandla e-acousti angaqokelelwa kwinxalenye yokungasebenzi kakuhle.

Umgca wommiselo wesithethi:
Uluhlu lomgcaliqela lemitha elilungiselelwe imigca ethe ngqo kwaye lisondele kakhulu, kwaye libe nenqanaba elifanayo kunye nesigaba. Ukuphucula umgama othumelayo kwaye unciphise i-aturetiations ngexesha losulelo olululo. Umxholo woluhlu lwelayini ayikho kuphela namhlanje. Yaphakanyiswa kwasekuqaleni yi-HF Olson, iNgqondo yeAmerican yaseMelika edumileyo. Ngo-1957, uMnu. Oku kungenxa yokuba kulungelelaniswe umgca ngokuhambelana ngqo nendlela elungileyo yokugubungela iziphumo ezilungileyo zesandi.
Umgca Uthethar izicelo:
Ingasetyenziselwa ukusetyenziswa kweselula okanye ufakelo olusisigxina. Ingathwalwa okanye ixhonywe. Inoluhlu olubanzi lokusetyenziswa, njengokunyamezelana kwemisebenzi, iikonsathi, iithiyetha, izindlu, njalo njalo. Ingasetyenziselwa ukusetyenziswa kweselula okanye ufakelo olusisigxina. Umgca wesithethi esithe nkqo se-verication ye-Axis ephambili yi-beam emxinwa, kwaye i-promovision yamandla inokuphakama imigama emide.
