Sib Nqus kua - dej ntws upwards

Sib Nqus kua - ib tug tshwj xeeb cov txiv neej-ua txuj ci tseem ceeb, creation ntawm kev kawm thiab kev xav ntawm lub thib nees nkaum caug xyoo. Nyob rau hauv sib piv rau lub feem ntau ntawm cov inventions ntawm tib neeg ntse heev, xws li ib tug kua yeeb tshuaj, nrog muaj zog sib nqus, tsis muaj analogues nyob rau hauv qhov. Nrog ceev ceev txoj kev loj hlob ntawm technology, ib tug yam ntxwv ntawm peb lub sij hawm, tej nrog xws li tej yam txawv zog yog ntau daim ntaub ntawv.

Sib Nqus kua yog ib tug zoo ncua kev kawm ntawv, nyob rau hauv lwm yam lus, ib tug colloidal tshuaj ntawm ferromagnetic khoom nyob rau hauv ib tug pa kua nruab nrab uas tseem yuav mus ua zoo tib yam dej, thiab hydrocarbons, thiab silicon los yog organofluorine tshuaj. Muaj xws txawv txawv tshuaj rau ib ntev lub sij hawm. Rov qab nyob rau hauv nruab nrab-sixties lawv tsim nyob rau hauv lub tebchaws United States thiab cov Soviet Union yuav luag txhij.

Thaum lub sib nqus kua siv nyob rau hauv ntau yam qhov chaw cov kev pab cuam, uas ob tug superpowers ua sib. Ib tug dav ntau ntawm cov kev zej zog cov txawv txawv yam muaj ua muaj tsis ntev los no. Tam sim no lub magnetic kua tau raug kawm feem los ntawm feem ntau tsim lub teb chaws uas muaj scientific tej zaum: Nyiv, Fabkis, Lub teb chaws Yelemees, Great teb chaws Aas Kiv thiab lwm tus neeg.

Cov tsab tshuaj cim nws zoo heev ua ke nrog ntawm theem siab tawm los lub dag lub zog nrog exceptional sib nqus, nyob rau hauv uas ntawm kaum txhiab txiav txim ntawm qhov ntau siab tshaj tej ntawm cov paub kua. Ntawm daim card yog ib tug zoo kawg li magnetization nyob rau hauv ferromagnetic ntaub ntawv dispersed rau ib tug loj tsis siab tshaj kaum nanometers, thiab lawv tom ntej kev taw qhia mus rau hauv ib tug dog dig kua nruab nrab.

Yog li, ib yam khoom uas muaj zoo heev fluidity yog chiv nyeem unimaginable tooj haib tej yam me me tas mus li magnet kheej kheej zoo. Txhua nanoparticle yog coated tiv thaiv-tshuaj tsw ntxhiab zaj duab xis uas tiv thaiv lawv los ntawm so ua ke. Lub thermal tsab ntawv tsa suab ntawm me me hlau nplaum muab thoob plaws hauv lub ntim ntawm lub substance, li no txhob hauv ntawm tus hais rau hauv qab. Raws li ib tug tshwm sim, lub magnetic kua yog tau muaj nws tus kheej cim zoo thiab kev kawm ntawv rau ntau xyoo.

Txhua me me magnet across yeej nyob rau hauv lub kua nyob rau hauv lub cawv ntawm tshav kub. Cov sab nraud magnetic teb nyob rau hauv ib txoj kev taw qhia kom paub sib nqus lub sij hawm ntawm lub microparticles, uas ua rau cov kev hloov nyob rau hauv lub kho qhov muag, rheological thiab sib nqus ntawm lub colloidal tshuaj. Thiaj li, ib theem siab ntawm rhiab heev ntawm lub slurry mus rau lub txheej magnetic teb qhov twg los muab lub peev xwm los kho lawv tus cwj pwm. Yog li, lub controllability thiab acquires magnetic kua nws tus kheej, cov kev siv ntawm cov uas nws ua tau rau ib tug ntau ntawm cov ntaub ntawv sau npe.

Ferromagnetic ncua kev kawm ntawv twb siv nyob rau hauv qhov siv thiab ua nyuaj disks, qhov uas lawv yuav thov mus rau yam ncej los mus tiv thaiv lub ingress ntawm txawv teb chaws teeb meem los ntawm sab nraum. Tej kev rho tawm kuj siv nyob rau hauv qhov siv thiab ua high-zaus hais lus nyob rau hauv lub khoos kas aerospace thiab tiv thaiv kev lag luam, optics thiab tshuaj, electronics thiab ntsuas-ua kev lag luam.
