Dej Hnyav (D2O) lossis deuterium oxide yog tsim los ntawm ob lub atom ntawm deuterium thiab ib atom ntawm oxygen. Deuterium yog ib qho isotope ruaj khov ntawm hydrogen nrog ob npaug ntawm qhov loj ntawm hydrogen vim muaj cov neutron ntxiv hauv nws cov nucleus. Deuterium muaj nyob rau hauv hydrogen thiab hydrogen bearing compounds xws li dej, hydrocarbons, thiab lwm yam.
Yuav ua li cas yog isotope ntawm hydrogen hnyav hauv dej?
Ib daim ntawv cog lus ntawm ob lub atom hydrogen thiab ib qho oxygen atom ua dej. Nyob rau hauv lub teeb dej-txog deb ntawm cov dej ntau tshaj plaws nyob rau hauv cov xwm-ob hydrogen atoms yog ob qho tib si ntawm Hydrogen-1 isotope, thaum nyob rau hauv cov dej hnyav, cov hydrogen atoms yog ob qho tib si ntawm the Hydrogen-2 isotope.
Yuav ua li cas isotope hu ua dej hnyav?
Deuterium, (D, lossis 2 H), tseem hu ua hnyav hydrogen, isotope ntawm hydrogen nrog lub nucleus uas muaj ib qho proton thiab ib neutron, uas yog ob npaug ntawm qhov loj ntawm lub nucleus ntawm cov hydrogen zoo tib yam (ib proton). Deuterium muaj qhov hnyav atomic ntawm 2.014.
Yuav ua li cas isotope ntawm hydrogen hnyav tshaj?
Tritium yog qhov hnyav tshaj plaws thiab tsuas yog xov tooj cua isotope ntawm hydrogen, muaj qhov loj ntawm 3. Lub nucleus, muaj ob lub neutrons thiab ib qho proton, tsis ruaj khov thiab lwj mus rau3Nws dhau los ntawm emission ntawm β particle nrog lub zog siab tshaj plaws ntawm kwv yees li 18 keV thiab lub zog nruab nrab ntawm kwv yees li 5.7 keV.

Vim li cas cov dej phwj hauv lub Hoobkas ua rau muaj kev phom sij rau cov kab mob hauv dej?
Cov kab mob paug paug los ntawm cov dej phwj tuaj feem ntau ua rau nyob rau hauv cov kab mob sib kisuas kis tau cov dej hauv dej thiab cov neeg hauv av los ntawm dej haus. Organic teeb meem thiab cov as-ham ua rau muaj kev nce hauv aerobic algae thiab depletes oxygen los ntawm cov dej.
Nyob rau hauv cov nroj tsuag ntawm cuscuta qhia siab tshaj plaws photosynthesis nyob rau hauv?
Yuav kom nqus cov xim xiav ntawm lub teeb hauv qhov ntau tshaj plaws, qhov siab tshaj plaws ntawm photosynthesis tshwm sim hauv red light. Yog li, lo lus teb raug yog, 'Lub teeb liab' . Qhov twg ntawm cov nroj tsuag cuscuta ua photosynthesis?
Nyob rau hauv tus txheej txheem desalination twg ntawm cov hauv qab no yog tshem tawm ntawm dej?
Desalination yog ib txheej txheem uas tshem tawm ntsev ntau dhau thiab lwm yam minerals tawm ntawm dej. Nyob rau hauv feem ntau cov txheej txheem desalination, pub dej yog kho thiab ob kwj dej yog tsim: kho cov dej tshiab uas muaj tsawg concentrations ntawm ntsev thiab minerals .
Nyob rau hauv teb rau qhov tuaj txog ntawm acidic chyme nyob rau hauv lub duodenum?
Pab plab hnyuv . theem plab hnyuvtshwm sim hauv duodenum raws li cov lus teb rau cov chyme tuaj txog, thiab nws txo qis kev ua pa ntawm plab los ntawm cov tshuaj hormones thiab lub paj hlwb reflexes . Yuav ua li cas teb rau qhov tuaj txog ntawm acidic chyme hauv duodenum?
Yuav ua li cas yog isotope ntawm hydrogen yog radioactive?
Tritium yog tib qho ntawm peb cov hydrogen isotopes uas yog xov tooj cua. Cov khoom siv hluav taws xob xws li tritium yuav hloov pauv mus rau hauv ib qho atom sib txawv hauv cov txheej txheem hu ua radioactive decay . Yuav ua li cas isotope ntawm hydrogen yog cov xov tooj cua tshaj plaws?
