Pab txhawb rau Txhais . Sib Nqus Particle Test (MPT), kuj hu ua Magnetic Particle Inspection , yog qhov tsis muaj kev puas tsuaj kev tshuaj xyuas (NDE) cov txheej txheem siv los txheeb xyuas qhov chaw thiab me ntsis subsurface flaws nyob rau hauv feem ntau ferromagnetic cov ntaub ntawv xws li hlau, npib tsib xee, thiab cobalt, thiab ib co ntawm lawv cov alloys.
Ib yam li ntawd, qhov kev ntsuam xyuas magnetic particle ua li cas?
Hauv magnetic particle soj ntsuam , ncig magnetization yog siv los xyuas cov kab nrib pleb ntev. dhau los ntawm ib feem los yog los ntawm ib qho hluav taws xob conductor nyob rau hauv ib feem. Lub voj voog Sib nqus teb txiav hla qhov tawg nyiam thiab tuav cov hmoov hlau, los qhia qhov tsis pom kev.
Tom qab, lo lus nug yog, dab tsi yog magnetic particle kuaj NDT? Magnetic particle soj ntsuam ( MPI ) yog a kev kuaj tsis muaj kev puas tsuaj ( NDT ) txheej txheem rau kev kuaj xyuas qhov chaw thiab qhov tob hauv qhov tsis sib xws hauv cov khoom siv ferromagnetic xws li hlau, npib tsib xee, cobalt, thiab qee yam ntawm lawv cov alloys. Cov txheej txheem tso ib Sib nqus teb rau hauv ib feem.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog lub hauv paus ntsiab lus ntawm kev ntsuam xyuas magnetic particle?
Cov magnetic particle kuaj Cov txheej txheem ntawm Kev Tshawb Fawb Tsis Muaj Kev Tshawb Fawb tau tsim nyob rau hauv Tebchaws Meskas, xyoo 1930, ua ib txoj hauv kev los xyuas cov khoom siv hlau ntawm cov kab ntau lawm. Cov txoj cai ntawm txoj kev yog tias cov qauv yog magnetized los tsim Sib nqus kab zog, los yog flux, nyob rau hauv cov khoom.
Kev kuaj Magnaflux yog dab tsi?
Magnaflux Magnetic particle soj ntsuam (MPI) kuaj cov khoom siv yog tsim los kom ceev ceev, txhim khu kev qha thiab muaj nuj nqis. Xav paub ntau ntxiv txog yuav ua li cas Magnaflux Cov cuab yeej tshuaj xyuas yog tsim los nrhiav cov cim qhia thiab qhov tsis xws luag xws li qaug zog tawg hauv cov ntaub ntawv ferrous los ntawm txoj kev ntub lossis qhuav mag particle kuaj.

Lub hauv paus ntsiab lus ntawm kev kuaj magnetic particle yog dab tsi?
Txoj kev sib nqus particle xeem ntawm Non-Destructive Examination yog tsim nyob rau hauv lub teb chaws USA, nyob rau hauv lub xyoo 1930s, raws li ib txoj kev los xyuas cov hlau Cheebtsam ntawm cov kab ntau lawm. Lub hauv paus ntsiab lus ntawm txoj kev yog tias cov qauv yog magnetized los tsim cov kab sib nqus ntawm lub zog, lossis flux, hauv cov khoom siv
Dab tsi yog txhais los ntawm quantization ntawm lub zog thiab quantization ntawm angular quantum?
Quantization ntawm angular momentum txhais tau hais tias lub vojvoog ntawm lub orbit thiab lub zog yuav quantized thiab. Bohr xav tias cov kab sib cais pom nyob rau hauv spectrum ntawm hydrogen atom yog vim kev hloov ntawm ib qho hluav taws xob los ntawm ib qho kev tso cai orbit / lub zog mus rau lwm qhov
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Dab tsi yog meant los ntawm yoj particle xwm ntawm lub teeb?
Hauv physics thiab chemistry, nthwv dej-particle dual tuav lub teeb thiab teeb meem pom cov khoom ntawm ob lub nthwv dej thiab cov khoom. Lub tswv yim ntawm duality yog rooted nyob rau hauv kev sib cav txog qhov xwm ntawm lub teeb thiab teeb meem yos rov qab mus rau 1600s, thaum sib tw theories ntawm lub teeb tau npaj los ntawm Christiaan Huygens thiab Isaac Newton
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
