Nyob rau hauv petrology, spherulites yog me me, sib npaug lub cev uas feem ntau tshwm sim hauv vitreous igneous pob zeb. Lawv feem ntau pom nyob rau hauv cov qauv ntawm obsidian, pitchstone, thiab rhyolite li globules txog qhov loj …
Kev loj hlob Spherulite yog dab tsi?
Ntau yam khoom siv (hlau alloys, polymers, minerals, thiab lwm yam) yog tsim los ntawm quenching kua rau hauv crystalline solids. Cov txheej txheem tsis sib xws no feem ntau ua rau polycrystalline kev loj hlob qauvuas tau hais dav dav "spherulites" vim tias lawv qhov loj-scale nruab nrab kheej kheej.
Dab tsi yog Spherulite hauv polymers?
Nyob rau hauv polymer physics, spherulites (los ntawm Greek sphaira=pob thiab lithos=pob zeb) yog spherical semicrystalline cheeb tsam hauv cov non-branched linear polymers. … Spherulites Lamellae, uas ua rau muaj zog dua, Hardness, tab sis kuj brittleness thaum piv rau disordered cheeb tsam hauv lub polymer.
Spherulite yog dab tsi?
Spherulites feem ntau yog ob-mineral aggregates (feem ntau yog quartz thiab feldspar), tsim los ntawm qhov pib spherulitic loj hlob ntawm ib qho ntxhia thiab tom qab crystallization ntawm cov ntxhia thib ob los ntawm cov kua lossis iav ntawm cov fibers.
fringed micelle qauv yog dab tsi?
Tus thawj fringed micelle qauv ntawm a crystalline polymer khoom xav tias ob theem, submicroscopical bundled saw crystals embedded nyob rau hauv ib qho amorphous matrix. … Ua keNrog rau cov khoom siv tsis muaj zog, xws li cov khoom sib txuas yog tsim los ntawm amorphous theem ntawm tib yam zoo li xav tau los ntawm cov qauv fringed micelle.
