Cleavage piav qhia qas a ntxhia tawg rau hauv qhov chaw tiaj tus (feem ntau yog ib, ob, peb lossis plaub qhov chaw). Cleavage yog txiav txim los ntawm cov qauv siv lead ua ntawm cov ntxhia . Kub: Thaum a ntxhia tawg nyob rau hauv peb cov lus qhia thiab cov kev tawg cov dav hlau tsim cov kaum sab xis (90 degrees rau ib leeg).
Ua kom pom qhov no, qhov cleavage ntawm cov ntxhia yog dab tsi?
Cleavage yog qhov nyiam ntawm a ntxhia txhawm rau ua kom cov dav hlau du sib npaug mus rau thaj chaw ntawm kev sib txuas tsis muaj zog. Fracture yog qhov nyiam ntawm a ntxhia kom tawg raws nkhaus nto yam tsis muaj cov duab meej. Cov no cov ntxhia tsis muaj cov dav hlau tsis muaj zog thiab tawg irregularly.
Tsis tas li, koj piav qhia txog cov zaub mov li cas? Cov yam ntxwv ntawm lub cev hauv qab no tuaj yeem siv tau yooj yim los txheeb xyuas cov ntxhia:
- Xim.
- Streak.
- Hardness.
- Cleavage los yog tawg.
- Crystalline qauv.
- Diaphaneity los yog Qhov Muaj Peev Xwm Pom Zoo.
- Tenacity.
- Magnetism.
Ib yam li ntawd, qhov txawv ntawm pob txha thiab cleavage nyob rau hauv ib qho ntxhia yog dab tsi?
Kev tawg yog tus yam ntxwv txoj kev a ntxhia tawg. Cov qhov sib txawv ntawm cleavage thiab tawg yog tias kev tawg yog qhov tawg ntawm lub ntsej muag siv lead ua qhov twg lub ntsej muag tshiab siv lead ua yog tsim qhov twg ntxhia tawg, hos tawg yog qhov "chipping" ntawm a ntxhia . Tsis sib xws - A tawg uas tawm ntawm qhov ntxhib los yog tsis xwm yeem.
Koj txhais li cas los ntawm cleavage?
Cleavage yog ib lo lus rau ib hom kev sib cais lossis kev sib cais: nws yog siv rau kev sib cais ntawm tus poj niam lub mis. Lo lus no nthuav vim kev tawg tsis yog tsuas yog kev sib cais xwb, tab sis nws tau txhais tau tias kev sib koom ua ke.

Yuav ua li cas cov tsev neeg ntawm kev ua haujlwm tsis thiab cov lus piav qhia ntawm cov duab cuam tshuam?
Cov tsev neeg muaj nuj nqi yog pab pawg ua haujlwm nrog qhov zoo sib xws uas ua rau lawv yooj yim rau kev teeb tsa thaum koj paub txog kev ua haujlwm ntawm niam txiv, qhov piv txwv yooj yim tshaj plaws ntawm daim ntawv. Ib qho parameter yog qhov sib txawv hauv cov kab zauv dav dav uas siv rau ntawm tus nqi tshwj xeeb txhawm rau tsim ib qho kev sib npaug
Cov nqe lus twg zoo tshaj plaws piav qhia txog qhov tseem ceeb ntawm cov lus qhia muaj nuj nqis?
Qhov tsis suav nrog tus nqi ntawm ib qho kev qhia rational yog qhov tseem ceeb uas tus denominator ntawm qhov kev qhia yog xoom. Tsis tas li ntawd, tus naj npawb ntawm zeros ntawm ib tug polynomial yeej ib txwm tsawg dua los yog sib npaug rau degree ntawm lub polynomial. Yog li ntawd, tus naj npawb ntawm cov txiaj ntsig tsis suav nrog cov lus qhia muaj txiaj ntsig tsis tuaj yeem tshaj li qib ntawm tus lej
Dab tsi yog qhov ntxhia cleavage nyob rau hauv plaub cov lus qhia?
Peb cov lus qhia cleavage: yog lawv sib tshuam ntawm 90˚ = cubic cleavage; yog cov ces kaum tsis yog 90˚ = rhombohedral. Minerals nrog 4 lossis 6 cleavages tsis yog ntau. Plaub lub dav hlau cleavage tuaj yeem tsim 8-sided duab = octahedral cleavage (piv txwv li, fluorite)
Dab tsi yog qhov txawv ntawm kev txiav txim siab cleavage radial cleavage thiab indeterminate cleavage?
Dab tsi yog qhov txawv ntawm indertermate thiab txiav txim cleavage? Indeterminate cleavage = deuterostomes(peb). radially cleave perpendicular rau polar axis. hlwb txoj hmoo tsis tau txiav txim ntxov rau
Dab tsi yog qhov txawv ntawm pob zeb cleavage thiab ntxhia cleavage?
RhombohedralThaum ib lub pob zeb tawg nyob rau hauv peb cov lus qhia thiab cov dav hlau cleavage tsim cov ces kaum uas yog lwm yam tshaj li 90 degrees. Cov duab tsim yog hu ua rhombohedron. Thaum cov pob zeb tawg hauv ib qho kev taw qhia, tawm hauv ib qho chaw tiaj tus (cleavage dav hlau)
