Magnesium yog qhov txawv ntawm aluminium los ntawm kev siv cov nyiaj nitrate. Cov tshuaj tsis hnov mob nrog aluminium , tab sis tso ib tug dub deposit ntawm nyiaj rau magnesium.
Kuj paub yog, qhov txawv ntawm txhuas thiab magnesium yog dab tsi?
Thaum aluminium alloys siv sij hawm ntev dua kom solidify piv rau magnesium alloys, nws cov alloys muab lub neej ntev dua. Hloov pauv, magnesium muaj lub sijhawm tshem tawm sai dua aluminium castings. Magnesium yog kuj zoo dua ntawm casting Cheebtsam nrog thinner phab ntsa thiab nruj tolerances dua aluminium.
Dab tsi yog qhov muaj zog aluminium lossis magnesium? Magnesium yog 33% sib dua aluminium , 60% sib zog dua titanium, thiab 75% sib zog dua hlau. Tab sis rau ntau daim ntawv thov nws yog muaj zog dua ib chav tsev ntim tshaj tag nrho peb ntawm cov qauv hlau.
Tsis tas li, koj tuaj yeem qhia qhov txawv ntawm aluminium thiab magnesium rims?
Cov khoom seem hlau khaws ib lub raj mis ntawm cov kua txiv hmab txiv ntoo ua ke qhia qhov txawv ntawm aluminium thiab magnesium . Yog nws npuas, nws yog magnesium . Kuv yuav ua nws hauv qhov chaw uas tsis tuaj yeem pom, thiab yaug nws zoo heev tom qab ntawd. Ib qho poob yuav tsum txaus.
Koj tuaj yeem qhia qhov txawv ntawm txhuas thiab txhuas?
Muaj ob peb txoj hauv kev yooj yim paub qhov txawv ntawm qhov sib txawv ntawm aluminium thiab coj . Ob qhov pom tseeb sib txawv yog qhov hnyav thiab yoog raws. Coj yog ib qho hnyav hlau piv rau aluminium . Coj kuj tau yooj yim molded rau ib qho kev zoo.

Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Koj tuaj yeem qhia qhov txawv ntawm Plutonic thiab pob zeb volcanic li cas?
Volcanic pob zeb yog pob zeb tsim thaum lavacools thiab solidifies ntawm lub ntiaj teb nto. Volcanic pob zeb tseem hu ua 'extrusive igneous pob zeb' vim lawv tsim los ntawm 'extrusion,' los yog eruption, ntawm lava los ntawm avolcano. Plutonic pob zeb yog pob zeb tsim thaum magma txias thiab solidifies hauv qab lub ntiaj teb nto
Koj tuaj yeem qhia qhov txawv ntawm qhov zoo li qub thiab dynamic quenching?
Lub static quenching mechanism yog tsim los ntawm ib qho intramolecular dimer ntawm tus neeg sau xov xwm thiab quencher, los tsim ib qho tsis muaj fluorescent hauv av-xeev complex nrog ib qho tshwj xeeb nqus spectrum. Hauv qhov sib piv, FRET quenching mechanism yog dynamic thiab tsis cuam tshuam rau qhov kev sojntsuam qhov nqus spectrum
Koj tuaj yeem qhia qhov txawv ntawm cov tshauv dawb thiab ntsuab li cas?
Ib tug tuaj yeem yooj yim paub qhov txawv ntawm cov tshauv ntsuab ntawm cov tshauv dawb los ntawm kev saib ntawm nplooj. Cov ntoo tshauv ntsuab yog me dua li cov ntoo tshauv dawb. Cov nplooj ntawm cov tshauv dawb tawm ntawm U-zoo li caws pliav qhov twg raws li cov nplooj ntsuab tshauv nplooj raws li D '"zoo li caws pliav. Cov tshauv dawb tau txais nws lub npe vim yog nplooj ntsuab ntsuab hauv qab
