Lub lim tiam no (10.23-10.27, tib yam hauv qab no), qhov kev cia siab rov qab los tseem tsis tau tuaj txog, thiab kev ua lag luam tau nrawm nrawm dua.Kev ua lag luam tsis muaj kev tiv thaiv, thiab kev thov ib leeg yog qhov nyuaj rau kev tsav tsheb.Raws li cov tuam txhab lag luam thiab cov tuam txhab lag luam sib tw rau nkoj, thiab cov kev txiav txim qis qis qis thiab txwv tsis pub, cov kev xav hauv nruab nrab cuam tshuam rau cov qauv ntawmtsawg ntiaj teb, zoo li lub caij nplooj zeeg cua, Xiaoxiao xa Yan Qun tam sim ntawd ~
Kev ua lag luam tau qaug zog heev rau lub lim tiam no, los ntawm kev poob qis thaum pib ntawm lub lim tiam mus rau qhov poob qis hauv nruab nrab ntawm lub lim tiam.Cov ntaub ntawv luv nqi lag luam feem ntau xau, ntxiv kev xav tsis zoo rau cov uas twb muaj lawmpraseodymium yog neodymium.Cov khoom lag luam txias txias, qhov chaw hloov pauv hloov pauv tas li, raws li kev pom zoo dav dav ntawm kev saib tsis muaj zog, qhov rov qab ntawm cov khoom muag oxide, thiab qhov nce ntawm kev muag khoom ntawm ore thiab cov khoom pov tseg yog txhua yam teeb meem uas cov chaw tsim khoom yuav tsum xav txog.Txawm hais tias qee lub tuam txhab hlau tau sim ua kom tus nqi ruaj khov, Tab sis nws kuj yuav tsum ua raws li tus nqi lag luam.
Hnyav tsis tshua muaj ntiaj tebkuj tau cuam tshuam los ntawm tag nrho cov tsis muaj zog, nrogterbiumcov khoom muaj kev poob qis tshaj plaws piv raudysprosium.Vim qhov kev thov txias thiab tsis muaj kev tiv thaiv, qhov feem ntawm cov khoom xa tuaj hauv kev lag luam ntau tau nce, thiab cov nyiaj tau los kuj tseem loj.Nyob rau hauv lub sij hawm luv luv, thaum tsis muaj kev cia siab, hloov pauv hloov pauv ntawm ntau yam tau ua kom qhov poob ntawm cov nqi pauv.Ntawm chav kawm, nyob rau hauv kev ua lag luam uas tsis muaj zog, ib qho ntau yam kuj nyuaj rau kev sib tw nrog.
Lub lim tiam no, nws tsim nyog them nyiaj rauceriumcov khoom.Vim qhov nce hauv kev tsim cov cerium hlau boron, qhov kev thov rau cov hlau cerium tau nce siab.Txawm li cas los xij, cov nroj tsuag sib cais tsis ntev los no tau pauv ntau dua hauv daim ntawv ntawm yav tom ntej, uas ua rau muaj kev sib tw me ntsis.Cov lus hais raucerium oxidetau nce tsis tu ncua, thiab cov nqi sib pauv tau chaotic.
Raws li lub Kaum Hlis 27th, qee cov khoom siv hauv ntiaj teb tsis tshua muaj tau hais tus nqi ntawm 45-4700 yuan / ton raucerium oxidethiab 2400-2500 yuan / ton raumetallic cerium; Praseodymium neodymium oxide hmoovyog 50800-512000 yuan/ton, thiabhlau praseodymium neodymiumyog 625-63000 yuan / tuj;Neodymium oxide hmoovyog 512-517000 yuan/ton, thiabhlau neodymiumyog 635-64000 yuan/ton;Dysprosium oxideyog 2.65-2.67 lab yuan / ton,dysprosium hlauyog 2.58-2.6 lab yuan / tuj;8.15-8.2 lab yuan / ton ntawmterbium oxide, 10.2-10.3 lab yuan / ton ntawmhlau terbium; Gadolinium oxide hmoovyog 268-273000 yuan/ton,gadolinium hlauyog 265000 yuan/ton;Holmium oxidetus nqi 580000 txog 590000 yuan/ton.Kev lag luam nquag ntawm cov hlau thiab oxide nyob rau hauv nruab nrab lub lim tiam ua rau cov nqi qis heev uas dej nyab lub khw, uas tseem nyob ruaj khov nyob rau tom qab ntawm lub lim tiam.Kev ua lag luam tag nrho yog nyob rau hauv kev tos-thiab-saib thiab stalemate, nrog cov nqi stabilizing thiab cov kev lag luam tiag tiag tau txais txiaj ntsig.
Txawm tias tsis tu ncua poob rau hauvtsawg ntiaj tebpauv tus nqi lub lim tiam no, piv rau lub lim tiam dhau los,praseodymium yog neodymiumtau nqis los ntawm 1.4 feem pua cov ntsiab lus.Nyob rau tib lub sijhawm, kev lag luam kev xav kuj tseem ceeb dua: ntawm ib sab, muaj ntau qhov chaw pov tseg thiab cov ore raw;Ntawm qhov tod tes, qhov teeb meem kev txiav txim rau cov khoom siv hlau nplaum qis qis tsis zoo.Vim qhov kev hloov pauv qeeb ntawm cov nqi hlau piv rau cov nqi oxide, nws yog qhov nyuaj rau kev ua tiav synchronous correspondence.Yog li ntawd, cov tuam txhab lag luam xav kom cuam tshuam kev xa khoom ntawm tus nqi theoretical ntawm cov hlau thiab cov nqi sib pauv.
Lub lim tiam no lub rooj sib tham tsis tu ncua ntawm Lub Xeev Pawg Neeg Saib Xyuas tau hais meej tias nyiaj txiag yuav tshaj tawm ntxiv 1 trillion yuan ntawm cov nyiaj khaws cia hauv lub quarter thib plaub, tag nrho cov no yuav raug xa mus rau tsoomfwv hauv nroog.Txawm hais tias cov kev taw qhia kev nqis peev tseem yog qhov tseem ceeb hauv kev tsim kho vaj tse thiab kev tsim kho tom qab kev puas tsuaj, qhov kev cia siab zoo tau lees paub qhov kev loj hlob ntawm Tuam Tshoj tus GDP kev loj hlob ntawm 5.2% nyob rau hauv tag nrho lub xyoo, thiab nws tseem tuaj yeem paub tseeb tias qhov kev txo qis ntawm lub tuam txhab nyiaj hauv nruab nrab hauv nruab nrab yuav raug txo qis. txoj kev, tab sis nws muaj kev cuam tshuam me ntsis rau cov khoom tsis yog ferrous thiab cov khoom dub hauv qhov tshwj xeeb.
Qee qhov kev lag luam muaj ntau lub tswv yim ntawm kev lag luam yav tom ntej:
1. Raws li qhov kawg ntawm lub hli dhau los, cov khoom siv ntxiv tuaj yeem tos ntev dua, yog li nws nyuaj rau cov nqi txhim kho.
2. Raws li qhov kawg ntawm lub xyoo dhau los, kev ua haujlwm ntawm cov lag luam loj kuj yog ib qho tseem ceeb cuam tshuam rau cov nqi lag luam, nrog rau qhov muaj peev xwm ua kom muaj kev ruaj ntseg tsawg kawg nkaus.
3. Tsis zoo li lwm cov hlau tsis muaj hlau, cov av tsis tshua muaj kev cuam tshuam los ntawm cov cai.Raws li kev sib koom ua ke ntawm cov lag luam loj thiab kev ua lag luam, txawm hais tias tej zaum yuav muaj peev xwm hloov kho kev lag luam rov qab mus rau qib qis rau lub sijhawm, lwm yam kev txhawb nqa kuj yuav tsum tau them nyiaj rau.
