Terbium yog siv Raws li ib tug dopant nyob rau hauv calcium fluoride, calcium tungstate, thiab strontium molybdate, cov ntaub ntawv uas yog siv nyob rau hauv cov khoom siv hauv lub xeev, thiab raws li cov siv lead ua stabilizer ntawm cov roj hlwb uas ua haujlwm ntawm qhov kub siab, ua ke nrog ZrO2. Terbium kuj yog siv nyob rau hauv alloys thiab nyob rau hauv zus tau tej cov khoom siv hluav taws xob.
Ntawm no, terbium nyob qhov twg hauv ntiaj teb?
Tsis yog pom nyob rau hauv cov xwm li dawb keeb, tab sis yog muaj nyob rau hauv ntau yam minerals. Cov ore tseem ceeb tshaj plaws yog monazite, bastnasite thiab cerite. Cov chaw mining tseem ceeb yog Tuam Tshoj, Tebchaws Asmeskas, Is Nrias teb, Sri Lanka, Brazil thiab Australia thiab reserves fo terbium kwv yees li ntawm 300,000 tonnes.
Ib tug kuj yuav nug, leej twg nrhiav tau terbium? Carl Gustaf Mosander
Ib yam li ntawd, tib neeg nug, puas yog Terbium siv hauv xov tooj ntawm tes?
Zoo li cov khoom, Minerals, thiab qee yam khoom siv. Terbium dua yog ib qho ntawm ntau cov ntsiab lus hauv lub xov tooj (Nws lub cim yog "Tb"). Terbium yog siv nyob rau hauv Circuit Court boards thauj lub zog. Kub yog ib yam khoom thiab cov ntxhia hauv koj xov tooj.
Puas yog tib neeg lub cev siv terbium?
17 radioactive isotopes ntawm terbium nqa cov lej ntawm 147 txog 158 thiab 160 txog 164. Ib qho hluav taws xob isotope, terbium -149, ib siv hauv tshuaj. Cov isotope yog txhaj ncaj qha rau hauv cov qog nqaij hlav cancer hauv tus neeg mob lub cev.

Dab tsi ntawm pipette yog volumetric thiab nws siv rau dab tsi?
Lub volumetric pipette, noob pipette, lossis lub plab pipette tso cai rau kev ntsuas qhov tseeb (rau plaub qhov tseem ceeb) ntawm qhov ntim ntawm cov tshuaj. Volumetric pipettes feem ntau yog siv rau hauv analytical chemistry los ua cov kev daws teeb meem los ntawm lub hauv paus Tshuag thiab npaj cov kev daws teeb meem rau titration
Dab tsi yog kev siv cov saw hlau nuclear siv rau?
Nuclear chain reaction. Nuclear chain reactions yog cov tshuaj tiv thaiv uas tau txais lub zog nuclear, feem ntau los ntawm nuclear fission. Cov kev cuam tshuam ntawm cov saw hlau no yog qhov muab cov chaw tsim hluav taws xob nuclear nrog lub zog uas tom qab ntawd hloov mus ua hluav taws xob siv los ntawm tib neeg
Puas yog Terbium siv hauv xov tooj ntawm tes?
Zoo li cov khoom, Minerals, thiab qee yam khoom siv. Terbium dua yog ib qho ntawm ntau lub ntsiab lus hauv xov tooj (Nws lub cim yog 'Tb'). Terbium yog siv nyob rau hauv Circuit Court boards los thauj lub zog. Kub yog ib qho khoom siv thiab cov ntxhia hauv koj lub xov tooj
Dab tsi yog qhov sib npaug siv los xam tag nrho cov khoom siv hluav taws xob siv?
Cov mis uas txuas lub zog thiab lub zog yog: Zog = Lub Zog x Sijhawm. Chav tsev ntawm lub zog yog joule, lub zog ntawm lub zog yog watt, thiab chav tsev ntawm lub sijhawm yog qhov thib ob
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
