Nws yog cais los ntawm cov roj rods uas ua tau kom muaj cua sov. Hnyav dej yog zoo heev ntawm kev qeeb qeeb (moderating) neutrons , muab CANDU reactors lawv qhov tseem ceeb thiab txhais cov yam ntxwv ntawm siab " neutron kev khwv nyiaj txiag".
Tsis tas li ntawd, puas neutrons hla dej?
Dej as a neutron ntaub thaiv npog hauv case of neutrons , dej zoo kawg nkaus nruab nrab neutrons , tab sis nrog nqus ntawm neutrons los ntawm hydrogen nucleus theem nrab gamma rays nrog tus siab zog yog tsim.
Tsis tas li, dej puas yog neutron moderator? Dej yog ib qho zoo tus neeg saib xyuas tab sis hydrogens nyob rau hauv dej molecule muaj ib tug ncaj siab hla ntu rau neutron ntes, tshem tawm neutrons los ntawm cov txheej txheem fission.
Thib ob, neutron absorber yog dab tsi?
Neutron tshuaj lom. Hauv kev siv xws li nuclear reactors, a neutron tshuaj lom (tseem hu ua a neutron absorber los yog tshuaj lom nuclear) yog ib yam khoom uas muaj qhov loj neutron absorption hla ntu. Hauv cov ntawv thov no, absorbing neutrons feem ntau yog ib qho kev tsis txaus siab.
Vim li cas dej thiaj li zoo Thermalizer ntawm neutrons?
Teeb dej Hydrogen ua haujlwm zoo li a neutron moderator vim nws qhov loj yuav luag zoo tib yam li ntawm ib neutron . Qhov no txhais tau hais tias ib qho kev sib tsoo yuav txo tau qhov ceev ntawm qhov neutron vim yog txoj cai ntawm kev txuag lub zog thiab lub zog.

Kev txiav ntoo puas muaj feem cuam tshuam rau kev qhuav dej thiab dej nyab?
Deforestation ntawm ntoo ua rau dej nyab thiab drought heev, vim hais tias cov av loosens li khi vim txiav ntoo. Nyob rau hauv no txoj kev, nquag dej nyab thiab drought tshwm sim los ntawm Deforestation. Cov ntoo pab tuav cov av ua ke
Vim li cas boron yog ib qho zoo neutron absorber?
Thaum cov neutrons sib tsoo nrog cov nucleus ntawm atoms xws li uranium, lawv ua rau cov uranium atom fission (sib cais ua ob lwm, me atoms) thiab tsim lub zog. Vim tias nws tuaj yeem nqus tau cov neutrons, boron tuaj yeem siv los tiv thaiv cov tshuaj tiv thaiv. Nws yog qhov no isotope uas zoo ntawm absorbing neutrons
Puas yog acid rau dej lossis dej rau acid?
Thaum tshav kub kub tau tso tawm ntau heev uas cov tshuaj yuav ua rau kub hnyiab heev, txaws concentrated acid tawm ntawm lub thawv! Yog tias koj ntxiv cov kua qaub rau hauv dej, cov tshuaj uas cov ntaub ntawv yog diluted heev thiab qhov me me ntawm cov cua sov tso tawm tsis txaus rau vaporize thiab spatter nws. Yog li Ib txwm Ntxiv Acid rau dej, thiab tsis txhob thim rov qab
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
Lub ntuj puas xiav vim dej hiav txwv los yog dej hiav txwv xiav vim lub ntuj?
'Lub hiav txwv zoo li xiav vim liab, txiv kab ntxwv thiab daj (ntev wavelength teeb) yog absorbed ntau zog los ntawm dej tshaj yog xiav (luv wavelength light). Yog li thaum lub teeb dawb ntawm lub hnub nkag mus rau hauv dej hiav txwv, nws feem ntau yog xiav uas tau rov qab los. Ib yam li ntawd, lub ntuj xiav.'
