Kev nyuaj siab yog lub zog ua haujlwm ntawm pob zeb hauv ib cheeb tsam. Txhua lub pob zeb tuaj yeem strained. Lim Nws tuaj yeem yog elastic, nkig, los yog ductile. Ductile deformation kuj hu ua yas deformation. Cov qauv hauv geology yog cov yam ntxwv deformation uas tshwm sim los ntawm kev ruaj khov (nkim los yog ductile) mob.
Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog kev ntxhov siab hauv geology?
Kev nyuaj siab yog lub zog siv rau ib yam khoom. Hauv geology , kev ntxhov siab yog lub zog ib chav tsev uas muab tso rau ntawm ib lub pob zeb. Tension yog hom loj ntawm kev ntxhov siab ntawm divergent phaj ciam teb. Thaum lub zog sib npaug tab sis txav mus rau qhov sib txawv, cov kev ntxhov siab hu ua shear (daim duab 2).
Tom qab ntawd, lo lus nug yog, dab tsi yog strain piav qhia? Lim yog cov lus teb ntawm ib qho system rau kev siv kev ntxhov siab. Thaum cov khoom ntim nrog lub zog, nws ua rau muaj kev ntxhov siab, uas ua rau cov khoom deformation. Engineering mob yog txhais raws li tus nqi ntawm deformation nyob rau hauv cov kev taw qhia ntawm kev siv quab yuam muab faib los ntawm thawj qhov ntev ntawm cov khoom.
Tom qab ntawd, lo lus nug yog, dab tsi yog txhais los ntawm kev ntxhov siab thiab kev nyuaj siab?
Kev nyuaj siab yog lub internal resisting rog ib cheeb tsam tsim nyob rau hauv lub cev tiv thaiv deformation. Nws yog muab los ntawm. f = P / A qhov twg P = load thov thiab thaj tsam ntawm ntu ntu. Thaum mob yog ib qhov dimensionless kom muaj nuj nqis txhais raws li qhov ratio ntawm kev hloov nyob rau hauv dimension mus rau qhov qub dimension.
3 hom kab mob yog dab tsi?
Hauv kev teb rau kev ntxhov siab, pob zeb yuav raug mob peb hom sib txawv - elastic mob , cev mob , los yog tawg. Elastic mob yog thim rov qab.

Dab tsi yog qhov kev sib raug zoo ntawm kev ua lej ntawm qhov kev nyuaj siab khov kho thiab Mollality?
Kev nyuaj siab qhov chaw khov kho yog cov cuab yeej sib koom ua ke pom hauv cov kev daws teeb meem uas tshwm sim los ntawm kev qhia txog cov kuab tshuaj molecules rau cov kuab tshuaj. Cov ntsiab lus khov ntawm cov kev daws yog tag nrho qis dua li cov kuab tshuaj ntshiab thiab yog ncaj qha proportional rau molality ntawm cov kuab tshuaj
Dab tsi yog qhov txawv ntawm kev nkag siab dav dav BSH thiab kev nkag siab nqaim NSH?
12) Dab tsi yog qhov txawv ntawm qhov dav-sensitive heritability (BSH) thiab nqaim-sense heritability (NSH)? A) BSH yog ib qho kev ntsuas ntawm cov noob uas cuam tshuam rau qhov zoo, thaum NSH yog ib qho kev ntsuas ntawm cov noob nrog cov teebmeem loj. B) NSH muaj feem xyuam rau ib leeg-gene yam nkaus xwb
Dab tsi ntawm kev ntxhov siab yog compression?
Compression yog ib hom kev ntxhov siab uas ua rau cov pob zeb sib tsoo lossis sib tsoo. Nws tsom rau qhov nruab nrab ntawm lub pob zeb thiab tuaj yeem ua rau kab rov tav lossis ntsug. Nyob rau hauv kab rov tav compression kev nyuaj siab, lub crust yuav thicken los yog shorten
Dab tsi ua rau muaj kev ntxhov siab tshwm sim raws ntug hiav txwv?
Upwelling tshwm sim thaum cua tshuab hla dej hiav txwv saum npoo av thawb dej tawm ntawm ib cheeb tsam thiab cov dej hauv qab tau nce siab los hloov cov dej sib txawv. Cov txheej txheem thim rov qab, hu ua downwelling, kuj tshwm sim thaum cua ua rau cov dej saum npoo av ua raws li ntug dej hiav txwv
Kev nce siab thiab kev nyuaj siab yog dab tsi?
Lub sij hawm lub kaum sab xis ntawm qhov siab qhia lub kaum sab xis ntawm kab rov tav mus rau ib qho khoom. Ib tug neeg soj ntsuam kab ntawm qhov pom yuav yog saum toj no kab rov tav. Lub sij hawm lub kaum sab xis ntawm kev nyuaj siab qhia lub kaum sab xis ntawm kab rov tav mus rau ib qho khoom. Nco ntsoov tias lub kaum sab xis ntawm qhov siab thiab lub kaum sab xis ntawm kev nyuaj siab yog sib haum
