Cob alt ferrite, CoFe2O4 (CoO·Fe2 O3), tseem yog siv rau nws cov ntawv thov magnetostrictive xws li sensors thiab actuators, ua tsaug rau nws qhov siab saturation magnetostriction (~ 200 qhov chaw ib lab).
Dab tsi yog cov ntaub ntawv tsim nyog rau magnetostrictive transducer?
Magnetostrictive transducers muaj ntau tus nickel (los yog lwm yam khoom siv magnetostrictive) daim hlaulos yog laminations teem nyob rau hauv parallel nrog ib tug ntug ntawm txhua lub laminate txuas rau hauv qab ntawm lub tank txheej txheem los yog lwm qhov chaw kom vibrated. Ib kauj ntawm cov hlau yog muab tso rau ib ncig ntawm cov khoom siv magnetostrictive.
Magnetostrictive transducer yog dab tsi?
Ib lub magnetostrictive transducer ua rau siv hom khoom siv hlau nplaum uas siv cov hlau nplaum sib nqus ua rau cov atoms ntawm cov khoom ua ke, tsim kom muaj kev hloov pauv ntawm qhov ntev ntawm qhov cov ntaub ntawv thiab yog li ua ib tug high-frequency mechanical vibration.
Cov khoom ntawm magnetostrictive sensor yog dab tsi?
Nws muaj tsib lub ntsiab ntawm cov magnetostrictive sensor: Waveguide, txoj hauj lwm hlau nplaum, hluav taws xob, strain pulse detection system, thiab damping module. Feem ntau, lub waveguide xaim yog nyob rau hauv ib lub hau tiv thaiv thiab txuas nrog rau cov cuab yeej uas tau ntsuas.
Cov khoom siv twg yog siv rau hauv tus pas nrig rau cov nyhuv magnetostriction?
Ib ironpas nrig muab tso rau hauv ib tug sib nqus teb qhia raws nws ntev stretches me ntsis nyob rau hauv ib tug qaug zog magnetic teb thiab cog lus me ntsis nyob rau hauv ib tug muaj zog magnetic teb. Mechanically stretching thiab compressing ib tug magnetized hlau pas inversely ua fluctuations nyob rau hauv lub magnetization ntawm tus pas nrig.

Puas yog cov dab dab dab dab dab dab dab dab dab dab dab dab?
Myth: Ib tug dab tshos tsis yog neeg ncaj ncees yog tiasnws haum yog. Fact: Tu siab, qhov no yog ib lo lus tsis tseeb uas tau raug perpetuated los ntawm aversive trainers. Txawm hais tias haum rau lub caj dab kom zoo khawb rau hauv cov tawv nqaij rhiab nyob ib ncig ntawm lub caj dab, uas ua rau muaj kev puas tsuaj loj rau cov thyroid, esophagus, thiab trachea.
Puas yog lo lus cov khoom siv feem ntau lossis ntau tshaj?
Cov khoom siv tuaj yeem suav tau lossis suav tsis tau. Feem ntau, feem ntau siv, cov ntsiab lus, ntau daim ntawv yuav kuj yog cov khoom siv. Txawm li cas los xij, hauv cov ntsiab lus tshwj xeeb, daim ntawv ntau ntau kuj tuaj yeem yog cov ntaub ntawv xws li.
Qhov twg hauv qab no feem ntau muab faib ua cov khoom muaj nqis uas tsis yog tam sim no?
Kev faib cov khoom vaj khoom tsev tsis yog tam sim no piv txwv yog cov nyiaj tau txais, nyiaj ntsuab, thiab cov khoom muag. Cov cuab tam uas tsis yog tam sim no feem ntau muab faib raws li ib qho ntawm cov ntawv sau hauv qab no- khoom, cog, thiab khoom siv (PP&E);
Dab tsi lipoprotein feem ntau thauj cov roj cholesterol hauv cov ntshav?
Low-Density Lipoproteins (LDL) Cov khoom no tau muab los ntawm VLDL thiab IDL hais thiab lawv tseem muaj cov roj cholesterol ntxiv. LDL nqa feem ntau ntawm cov roj cholesterol uas nyob hauv txoj kev. Qhov tseem ceeb tshaj plaws apolipoprotein yog B-100 thiab txhua LDL particle muaj ib qho Apo B-100 molecule.
Puas yog cov txiaj ntsig tshwj xeeb - feem ntau cov khoom tsis yog nyiaj - rau cov thawj coj?
phiaj xwm txhawb nqa lub koom haum tuaj yeem siv cov tswv cuab hauv lub koom haum los muab nqi zog rau cov neeg ua haujlwm. … Yog tias tus nqi lag luam ntawm cov khoom lag luam tshaj tus nqi siv zog, cov neeg ua haujlwm tuaj yeem siv qhov kev xaiv thiab yuav cov Tshuag.
