Nyob rau hauv qhov sib txawv ntawm qhov deformation nkig, ductile deformation mechanisms feem ntau yuav tshwm sim ntawm qis dua kev ntxhov siab thiab siab dua P-T cov xwm txheej uas cuam tshuam rau nruab nrab-rau-qis crust thiab sab sauv mantle ib puag ncig.
Qhov twg yog brittle vs ductile deformation tshwm sim?
Brittle deformation: Irreversible strain thaum pob zeb tawg hauv daim teb rau kev ntxhov siab. Txhua yam khoom uas tawg mus rau hauv daim ntawv qhia txog tus cwj pwm nkig. Ductile deformation: thaum cov pob zeb ntws los yog khoov rau hauv cov lus teb rau kev ntxhov siab (xws li av nplaum).
Dab tsi deformation tshwm sim nyob rau hauv sab sauv thiab qis crust?
Nyob rau hauv lub sab saum toj crust qhov twg brittle tsis ua hauj lwm yog hom tseem ceeb ntawm deformation, ib tug infinitely ntev ntsug creeping txhaum yog assumed nrog lub txhaum tawm tsam parallel rau lub y-axis. Cov crust qis yog deformed los ntawm cov yas ntws, thiab muaj cov txheej txheem ib nrab ntawm qhov nruab nrab ntawm sab sauv thiab sab qis.
Ntawm qhov tob npaum li cas yog qhov deformation tshwm sim?
Ntawm qhov tob ntawm kwv 15 km peb mus txog qhov chaw hu ua brittle-ductile transition zone. Hauv qab no lub pob zeb lub zog txo qis vim tias cov pob txha tawg raug kaw thiab qhov kub thiab txias siab dua, ua rau cov pob zeb coj tus cwj pwm zoo.
pob zeb deformation tshwm sim nyob qhov twg?
pob zeb ua deformed thaum lub ntiaj teb lub pob zeb yog compressed los yog stretched. Lub zog xav tau los ua qhov no ntau lab xyoo - deformation yog qeeb heevtxheej txheem!

Thaum muab piv cov kab kab kab thiab cov kab ntsig flatworms qhov twg muaj tseeb?
Ib tug flatworm muaj nyias, dorsoventrally flattened lub cev. Roundworms yog ntau cylindrical hauv cov duab thiab tapered mus rau qhov zoo ntawm ib kawg. Ib yam li ntawd, cov kab mob roundworms muaj ib txheej txheej txheej hu ua cuticle uas lawv tau rov ua dua thoob plaws hauv lawv lub neej thiab thaum lawv loj hlob.
Thaum twg brittle deformation tshwm sim?
Kev deformation tuaj yeem tshwm sim raws li kev sib koom ua ke (tseem hu ua tawg lossis tensile tawg) uas tsis muaj kev hloov pauv tshwm sim raws li qhov tsis sib xws, lossis ua txhaum qhov kev hloov pauv. tshwm sim. 'Shear fracture' yog siv los hais txog qhov hloov pauv me me uas tshwm sim los ntawm qhov pib tsim ntawm pob txha.
Cov kab kab kab kab kab ua kab mob txaus ntshai npaum li cas?
Nyob rau hauv peb thiab tom ntej instars ntawm lawv txoj kev loj hlob, Pine processionary caterpillars yog mob heev rau daim tawv nqaij ntawm tib neegthiab lwm yam tsiaj. Kev sib cuag yooj yim nrog cov plaub hau ntawm kab ntsig tuaj yeem ua rau pob khaus hnyav (urticaria) thiab khaus qhov muag, thiab qee tus neeg yuav muaj kev fab tshuaj.
Thaum twg qhov kev rov tshwm sim tshwm sim?
Thaum Replevin tuaj yeem thov Li no, qhov no yog qhov xwm txheej tshwm sim ntau tshaj plaws uas yuav tshwm sim thaum tus neeg siv khoom tsis raug them nyiaj qiv tsheb. Kev ua txhaum cai ntawm kev thaj yeeb nyab xeeb yog me ntsis luv luv. Nws tsis suav nrog kev txeeb tsheb yam tsis tau ceeb toom lossis kub xov tooj kom tsav tsheb mus.
Thaum qhov no yog qhov tshwm sim uas tshwm sim?
Lub hauv paus ntsiab lus ntawm kev mob Nrog qhov tshwm sim (uppada) ntawm qhov no, qhov tshwm sim. Thaum tsis muaj qhov no, qhov ntawd tsis tuaj. Nrog lub cessation (nirodha) ntawm no, uas ceases. - Samyutta Nikaya 12.61. Thaum qhov no yog qhov tshwm sim uas tshwm sim qhov tshwm sim uas tshwm sim thaum qhov no tsis yog qhov tsis yog qhov kev txiav txim siab tsis piav qhia?
