Ke hobane'ng ha ho e-na le lipululana lintlheng tsa tjheseletsa tsa mochini oa tjheseletsa oa maqhubu a mahareng?Sebopeho sa li-bubble pele se hloka hore ho thehoe mokokotlo oa bubble, o lokelang ho finyella maemo a mabeli: e 'ngoe ke hore tšepe ea metsi e na le khase ea supersaturated,' me e 'ngoe ke hore e na le matla a hlokahalang bakeng sa nucleation.Tlhahlobo le tharollo ea bothata ba li-bubble tse kopaneng tsa solder:
The supersaturation ka tšepe ea metsi e batla e phahame, 'me ha e ntse e phahama, e fetoha e sa tsitsang le ho feta.Ho na le monyetla oa hore khase e na ebe e etsa lipululana.Ka hona, letamo le qhibilihisitsoeng ka tjheseletsa le na le maemo a hlokahalang a supersaturation ho theha li-bubble.Joalo ka ts'ebetso ea kristale ea tšepe, bubble nucleation le eona e ka etsahala ka litsela tse peli: nucleation e itlelang feela le nucleation e sa itlelang feela.Haeba bubble mantlha e thehoa, bubble e tlameha ho hlola khatello ea metsi le ho etsa mosebetsi oa ho atolosa
Ka lebaka la keketseho ea matla a holim'a metsi e bakoang ke ho thehoa ha mekhahlelo e mecha, haeba mokokotlo oa bubble o nang le boholo ba bohlokoa o etsoa ka metsi, matla a lekaneng a tlameha ho fanoa ho theha matla a nyutlelie.Ho hlakile hore ha matla a nucleation a phahame, ho na le monyetla o fokolang oa ho theha motheo oa bubble.Ka lehlakoreng le leng, ho bonolo ho theha motheo oa bubble.
