Lub Tsib Hlis 11, Lub Chaw Haujlwm Saib Xyuas Kev Tshawb Fawb Hauv Tebchaws tau tshaj tawm cov ntaub ntawv. Lub Plaub Hlis, lub teb chaws cov nqi ntawm cov khoom lag luam tsim khoom nce 6.8% xyoo-rau-xyoo thiab 0.9% nyob rau lub hli; tus kws tsim khoom lag luam kev nce nqi tau nce 9.0% xyoo-rau-xyoo thiab 1.3% nyob rau lub hli. Qhov nruab nrab ntawm Lub Ib Hlis mus txog Lub Plaub Hlis, cov nqi qub ntawm cov khoom lag luam rau cov neeg tsim khoom lag luam tau nce 3.3% piv rau tib lub sijhawm dhau los, thiab tus nqi yuav khoom rau cov neeg tsim khoom lag luam tau nce 4.3%.
Lub xyoo hloov xyoo ntawm tus nqi tsim khoom lag luam. Ntawm cov ex-Hoobkas nqi ntawm cov neeg tsim khoom lag luam, tus nqi ntawm cov txhais tau tias kev tsim khoom tau nce 9.1%, nce ntawm 3.3 feem pua cov ntsiab lus ntawm lub hli dhau los, cuam tshuam qhov nce tag nrho ntawm cov ex-Hoobkas nqi ntawm cov neeg tsim khoom los ntawm kwv yees li 6.76 feem pua ntsiab lus Cov. Ntawm lawv, tus nqi ntawm kev lag luam mining thiab kev lag luam chaw txua txiag zeb tau nce 24.9%, tus nqi ntawm kev lag luam khoom lag luam nce ntxiv li 15.2%, thiab tus nqi lag luam kev lag luam tau nce los ntawm 5.4%. Ntawm cov nqi yuav khoom ntawm cov neeg tsim khoom lag luam, tus nqi ntawm cov hlau tsis muaj cov khoom siv thiab cov xov hlau tau nce 23.3%.
Tom qab xyoo ntawm txoj kev loj hlob, kuv lub teb chaws' s tsis yog xim hlau tshiab cov ntaub ntawv tshawb fawb tau zoo kawg li, thiab qhov kev vam meej tau ua tiav ntawm kev siv thev naus laus zis ntawm cov ntaub ntawv tshiab thiab kev tshawb fawb ntawm cov ntaub ntawv ua tau zoo. Cov kev ua tau zoo ntawm cov ntaub ntawv tshiab xws li txhuas alloys tau zoo dua. High-lub zog aluminium-lithium alloys thiab txau-txau-ceev ceev sai solidification series ntawm tshav kub-aluminium alloys tau mus txog qib siab dej qauv ntawm thoob ntiaj teb txhuas cov ntaub ntawv. Pib xyoo kaum xyoo, kuv lub teb chaws tau ntxiv dag zog rau kev tshawb fawb txog ntau yam ntawm cov tawv-tawv, lub zog thiab lub zog tiv thaiv kev tiv thaiv alloys, kom qhov kev ua tau zoo ntawm lawv cov alloys tau raws li cov qauv hauv Tebchaws Meskas, thiab tau tiav loj -scale ntau lawm. Xyoo tsis ntev los no, kuv lub teb chaws tau ua tiav tshawb nrhiav thiab tsim hluav taws xob high-voltage anode capacitor aluminium foil, uas muaj cov txiaj ntsig zoo piv nrog cov khoom zoo sib xws hauv Nyij Pooj, thiab tau ntxiv dag zog tshawb fawb ntawm cov txheej txheem thev naus laus zis technology, thiab tau paub txog kev tsim hluav taws xob loj txhuas ntawv ci. Nyob rau hauv cov xwm txheej zoo li no, Nyij Pooj xa tawm mus rau kuv lub teb chaws Cov roj av aluminium capacitor tsis muaj kev sib tw kom zoo dua, thiab tus nqi tau poob qis heev.
Ua ib lub teb chaws nplua nuj nyob hauv cov hlau magnesium hlau, txawm hais tias cov kev tshawb fawb thiab daim ntawv thov ntawm cov khoom siv hlau nplaum hauv Suav teb pib lig, kev txhim kho ntawm cov hlau nplaum alloys kuj tseem nrawm heev. Thaum xyoo 1990, qhov kev nthuav dav ntawm kev thov ntawm alloys magnesium hauv ntiaj teb txuas ntxiv mus. Tus nqi ntawm cov hlau txuas ntxiv mus nce, thiab tag nrho lub ntiaj teb tau tsim tawm thaum tshav kub kub ntawm silicothermic refining ntawm magnesium hlau. Tuam Tshoj cov hlau nplaum hlau tawm tau nce ntau. Txawm li cas los xij, txawm hais tias qhov tsim tawm thiab cov khoom siv ntawm cov hlau nplaum hlau ntau zuj zus txhua xyoo, Tuam Tshoj txoj kev txhim kho tshiab ntawm cov hlau alloys Txawm li cas los xij, muaj qhov tsis muaj kev sib sib zog nqus ntawm cov khoom siv, thiab kev tsim kho ntawm cov hlau nplaum hlau yog qhov poob qis. Tam sim no, Tuam Tshoj tau coj txoj kev loj hlob ntawm cov khoom siv hlau magnesium alloy tshiab tam li txoj haujlwm tshawb fawb txog kev tshawb fawb thiab thev naus laus zis. Hauv cov txheej txheem kev loj hlob ntawm ZMI-ZM10 qib, cov hlau nplaum txhuas hauv tsev qib Cov theem ntawm kev txhim kho thiab daim ntawv thov kuj tau ua tiav zoo. Kev ua kom huv huv, kho kom zoo, microalloying thiab lwm yam kev txhais tau tuaj yeem ua kom muaj kev txhim kho ntau ntxiv hauv kev ua tiav cov txheej txheem ntawm cov hlau nplaum alloys. Tam sim no, hauv kev lag luam maus taus thiab tsheb, cov ntaub ntawv tshiab xws li cov hlau nplaum hlau (alloy alloy castings) thiab cov hlau nplaum magnesium alloy tuag tau siv. Nws tau siv dav, thiab muaj peev xwm tsim tau 0.3 hli wrought magnesium alloy cov ntaub ntawv khoom. Lub thev naus laus zis ntawm cov hlau nplaum magnesium alloy advanced npaj xws li oxidation nto micro-arc kev kho tshuab ntawm cov hlau nplaum alloy, qhov kev tiv thaiv ib puag ncig technology ntawm magnesium alloy yaj, nplaim retardant thev naus laus zis ntawm magnesium alloy, thiab lwm yam Kev tshawb fawb thiab kev txhim kho.
Nrog txoj kev txhim kho ntawm kuv lub teb chaws' s lub teb chaws kev lag luam thiab kev ua kom nrawm ntawm kev tsim kho kev tiv thaiv kev tiv thaiv kev lag luam, kuv lub teb chaws' s tsis muaj hlau tsis muaj hlau tshiab cov khoom siv tshawb fawb thiab kev tsim kho tshiab tau maj mam tsim, tab sis nws kuj yuav tsum yog tau sau tseg tias kev txhim kho ntawm kuv lub teb chaws' s cov hlau tsis muaj hlau cov ntaub ntawv tshiab tseem qis tshaj li cov teb chaws tau tsim hauv lub ntiaj teb. Qib qib ntawm kev txhim kho thiab kev siv cov ntaub ntawv tshiab tsis yog siab. Txhawm rau kom tau raws li qhov xav tau ntawm kev hloov kho tshiab, nws tseem tsim nyog ntxiv dag zog rau kev tshawb fawb ntawm cov khoom siv high-precision tshiab.
