Lub ntsiab yog vim li cas rau khov thiab thawing ntawm pob zeb yog vim muaj ib qhov chaw - dej. Thaum lub capillary pores ntawm pob zeb nqus cov dej sib xws, cov dej hauv pob zeb yuav pib khov pob zeb txiav tshuab.thaum kub poob qis dua 0 ° C.
Feem ntau hais lus, teeb meem ua raws li txoj cai ntawm" Thaum tshav kub kub expansion thiab txias contraction", thaum dej yog qhov opposite. Qhov ntom ntawm cov dej yog qhov loj tshaj plaws ntawm 4 ° C, thiab cov dej molecules yog kua thiab ua haujlwm ntawm nws tus kheej. Thaum qhov kub ntawm cov dej qis qis ntawm 4 ° C mus rau 0 ° C, dej pob zeb diamond txiav tshuabmolecules nyob rau hauv cov dej khov yog teem nyob rau hauv ib tug peb-dimensional qauv nyob rau hauv ib tug txawv txawv xoob daim ntawv. Daim ntawv qauv no yeej tawm ntau" qhov" thiab qhov ceev txo. Kev sim tau pom tias thaum 1 cubic granite pom' meter ' dej khov, nws ntim nce mus rau 1.11 cubic meters.
Yog li ntawd, thaum cov dej nkag mus rau hauv lub qhov hws los yog qhov khoob ntawm lub pob zeb ntuj, nws khov thiab khov, thiab lub ntim nce, yog li nthuav cov pores lossis qhov khoob ntawm lub pob zeb ntuj. Tom qab ntawd, lub pob zeb ntuj absorbs dej ntau dua, thiab lub qhov hws lossis qhov khoob tau nthuav dav ntxiv xws li lub voj voog vicious, uas granite polishing tshuabnws thiaj li coj mus rau fragmentation ntawm ntuj pob zeb.
