Nyob rau hauv geology, degradation yog hais txog txo qis ntawmib qho chaw fluvial, xws li lub txaj kwj lossis dej nyab, los ntawm cov txheej txheem erosional. Aggradation (los yog alluviation) yog lo lus siv nyob rau hauv geology rau kev nce hauv av nce, feem ntau nyob rau hauv ib tug dej system, vim lub deposition ntawm sediment.
Dab tsi yog aggradation thiab degradation ua ke hu ua?
Fluvial deposition hais txog kev sib tw thiab nws. txuam landforms, fluvial erosion i.e. degradation yog cov. cov txheej txheem yooj yim uas yuav luag lub luag haujlwm rau kev hloov pauv hauv.
Dab tsi yog aggradation degradation?
Aggradation yog hais txog kev nce siab ntawm thaj av feem ntau hauv cov dej ntws vim kev tso cov sediments. Degradation tshwm sim vim erosional kev ua ub no ntawm cua thiab dej. Nws hais txog kev txo qis ntawm qhov av los ntawm cov txheej txheem erosional.
Ib qho piv txwv ntawm kev sib tw yog dab tsi?
Kev sib kis tuaj yeem tshwm sim los ntawm kev hloov pauv huab cua, kev siv av, thiab kev ua geological, xws li hluav taws kub tawg, av qeeg, thiab faulting. Piv txwv li, volcanic eruptions tej zaum yuav ua rau cov dej ntws los nqa cov av ntau tshaj li qhov ntws tuaj yeem thauj tau: qhov no ua rau lub faus ntawm cov qub channel thiab nws qhov dej nyab.
Kev degradation txhais li cas hauv thaj chaw?
Physical Geography. kev hnav hauv av los ntawm dej, cua, lossis dej khov.

Puas yog piv txwv ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov khoom siv hluav taws xob?
Piv txwv rau cov khoom siv tsis ncaj band sib txawv yog silicon (Si), germanium (Ge), aluminium arsenide (AlAs) thiab gallium phosphide (GaP) . Yuav ua li cas piv txwv ntawm indirect band gap? Piv txwv ntawm cov ntaub ntawv ncaj qha muaj xws li amorphous silicon thiab qee cov khoom siv III-V xws li InAs thiab GaAs.
Pfaffian qhov sib txawv qhov sib txawv yog dab tsi?
Daim ntawv dav dav ntawm Pfaffian equations hauv ob qhov sib txawv x thiab y yog P dx + Qdy=0, qhov twg P=P(x, y) thiab Q=Q(x, y) yog cov haujlwm ntawm x thiab y. … Yog hais tias peb tuaj yeem nrhiav cov haujlwm f=f (x, y) thiab g=g(x, y) xws li ω=gdf, ces ω=0 tuaj yeem raug txo kom df=0 nrog kev daws f(x, y)=c (c yog qhov tsis tu ncua) .
Dab tsi yog qhov sib txawv ntawm qhov sib txawv?
Nyob rau hauv nplooj ntawv no koj tuaj yeem tshawb pom 12 lub ntsiab lus, cov lus sib piv, cov lus qhia tsis zoo, thiab cov lus hais txog qhov tsis sib xws, xws li: antithesis , contraposition contraposition Nyob rau hauv ib txwm logic, contraposition yog ib daim ntawv ntawm tam sim no inference nyob rau hauv uas ib tug proposition yog inferred los ntawm lwm tus thiab qhov twg tus qub muaj rau nws cov ntsiab lus contradictory ntawm tus thawj logical proposition tus predicate
Rau cov roj zoo tagnrho uas qhov sib txawv yog qhov sib txawv ntawm qhov sib txawv?
Boyle txoj cai hais tias siab (P) thiab ntim (V) yog qhov sib npaug. Charles txoj cai hais tias ntim (V) thiab qhov kub thiab txias (T) ncaj qha proportional . Txoj cai roj twg yog qhov sib npaug sib npaug? Rau qhov loj ntawm cov roj zoo tagnrho khaws cia ntawm qhov kub thiab txias, siab thiab ntim yog qhov sib npaug.
Nyob rau hauv ib qho kev tsis sib haum xeeb pn kev sib tshuam cov kev sib tshuam tam sim no ntawm qhov sib npaug yog?
Nyob rau hauv qhov tsis ncaj ncees PN-kho qhov kev sib tshuam tam sim no ntawm qhov sib npaug yog zero, vim tias sib npaug tab sis cov neeg nqa khoom hla hla kev sib tshuam . Thaum pn kev sib tshuam tsis ncaj ncees qhov kev sib tshuam tam sim no ntawm qhov sib npaug yog?
