Magnetic Abrasive Finishing (MAF) yog ib qho ntawm tsis yog cov txheej txheem ua tiav, uas ua rau qib siab ntawm qhov zoo thiab feem ntau yog tswj los ntawm magnetic teb. Hauv MAF, cov khoom ua haujlwm tau khaws cia nruab nrab ntawm ob tus ncej (N thiab S) ntawm cov hlau nplaum.
Dab tsi yog qhov amplitude ntawm magnetic abrasive tiav?
Raws li kev vibration zaus ntawm (4, thiab 10 Hz) thiab 2 hli ntawm amplitude, cov txheej txheem ultra-high-precision sib nqus abrasive tiav tuaj yeem ua tiav ntawm AISI 1085 steel hlau workpiece nrog 16 hli ntev rau 60 s.
Qhov zoo ntawm kev sib nqus abrasive yog dab tsi?
Cov txiaj ntsig ntawm Magnetic Abrasive Finishing
Vim tias daim ntawv thov ntawm cov hmoov hmoov tsis xav tau kev sib cuag ncaj qha nrog cov khoom ua haujlwm lossis cov khoom, piv txwv li, nws tuaj yeem npog qhov nyuaj-mus txog qhov zoo li cov phab ntsa sab hauv. cev. Sib nqus abrasive xov kuj tseem zoo heev ntawm kev faib cov hmoov sib npaug.
Dab tsi yog qhov ua tiav ntawm cov hlau nplaum abrasive tiav MAF?
Magnetic abrasive finishing (MAF) yog txheej txheem kev ua tiav qib siab uas txiav quab yuam yog tswj los ntawm magnetic teb. Cov txheej txheem no muaj peev xwm muab nanometer-scale nto tiav.
Cov khoom twg tsis tuaj yeem ua rau sib nqus abrasive tiav?
Nyob rau hauv Sib Nqus abrasive xov, uas ntawm cov khoom hauv qab no tsis ua rau cov khoom sivtshem tawm? Kev piav qhia: Cov khoom raug tshem tawm los ntawm colloidal dispersion ntawm cov khoom sib nqushauv cov khoom abrasive. 6.

Dab tsi yog roj zoo rau kev sib sib zog nqus kib?
roj zaub yog cov roj zoo tshaj plaws rau kev sib sib zog nqus kib. Canola roj thiab txiv laum huab xeeb yog lwm cov kev xaiv nrov. Thaum cov roj zaub, roj canola, thiab txiv laum huab xeeb yog cov roj uas nyiam tshaj plaws rau kev sib sib zog nqus kib, muaj ob peb lwm cov roj uas koj xaiv tau:
Puas yog kev sib ntaus sib tua ntawm kev sib ntaus sib tua?
Kev sib ntaus sib tua ntawm Hastings, uas Anglo-Saxon huab tais Harold II tau sim tiv thaiv nws lub tebchaws los ntawm kev tawm tsam ntawm William, duke ntawm Normandy (tom qab hu ua William tus Conqueror), tau tshwm sim rau 14 October 1066.
Lub sijhawm fracking dab tsi yog muab rho tawm los ntawm qhov tsis sib haum xeeb sib sib zog nqus?
Hydraulic fracturing - feem ntau hu ua fracking - yog txheej txheem siv los rho tawm shale gas. Cov qhov tob yog drilled mus rau hauv lub pob zeb shale, ua raws li kab rov tav drilling kom nkag tau ntau dua ntawm cov roj reserves, raws li shale reserves feem ntau faib horizontally es vertically.
Puas kev sib koom ua ke hauv kev ntsuas txhais tau tias kev sib koom ua ke?
Feem ntau, pointwise convergence tsis txhais hais tias convergence nyob rau hauv ntsuas. Txawm li cas los xij, rau qhov chaw ntsuas qhov kawg, qhov no yog qhov tseeb, thiab qhov tseeb peb yuav pom hauv ntu no tias ntau qhov tseeb. Puas kev sib koom ua ke yuav luag txhua qhov txhais tau tias kev sib koom ua ke hauv kev ntsuas?
Puas muaj leej twg tau mus rau hauv qab ntawm qhov sib tw sib sib zog nqus?
Thaum ntau txhiab tus neeg nce toj tau ua tiav Mount Everest, qhov chaw siab tshaj plaws hauv ntiaj teb, tsuas yog ob tus neeg tau nqis mus raulub ntiaj teb qhov chaw tob tshaj plaws, Challenger Deep hauv Dej Hiav Txwv Pacific Mariana Trench.
