Ib txoj hauv kev los txhim kho lub davhlau kev nyab xeeb yog kev siv cov khoom kaw (on-board recording devices) (BUR) rau kev sau cia thiab kev soj ntsuam tom qab lub xeev ntawm cov kab ke loj ntawm cov dav hlau. Kev kub ntxhov ceev BUR hu ua "lub thawv dub", uas muaj kev tiv thaiv zoo tshaj plaws los ntawm kev poob siab thiab cov khoom cua sov, los ntawm cov teebmeem ntawm kev tawm tsam, thiab lwm yam.
Feem ntau, ob lub thawv dub tau muab tso rau ntawm lub dav hlau, ib qho ntawm qhov (hais lus) sau cov kws sib tham ntawm cov neeg coob, qhov thib ob (kev ntsuas) - dav dav tsis. Qhov no tuaj yeem yog cov ntaub ntawv hais txog kev ua haujlwm ntawm lub cav, hais txog kev nqis tes ntawm cov neeg ua haujlwm, txog cov xwm txheej huab cua, thiab lwm yam Hauv cov hlau nplaum DRUs, cov ntaub ntawv yog sau rau cov ntaub nplaum los yog cov hlau nplaum sib nqus, hauv cov khoom-khov kho - rau FLASH tsav.
Sab nraud, "lub thawv dub" thiab tsis dub, thiab tsis yog lub thawv - nws yog lub txiv kab ntxwv kheej kheej, sab hauv uas muaj cov cuab yeej kaw cia. Cov duab kheej kheej rau BUR tau raug xaiv vim tias nws tiv taus kev qoj ib ce zoo dua, thiab xim txiv kab ntxwv yog pom ntau dua thaum tshawb. Muaj kev tiv thaiv tsis pub caij nkoj lub nkoj (ZBN), raws li nws tseem hu ua, yuav tsum tiv qhov kev poob siab ntawm 1000 g, ua kom sov li 1000 C rau 50 feeb thiab nyob hauv qhov tob ntawm 6000 m rau ib hlis.
Txhawm rau kev tshawb fawb, cov xov tooj cua tsim tau rau hauv "thawv dub", uas tau muab tso ncaj qha tom qab muaj xwm txheej. Qhov kev xyaum no tau muab tso rau hauv seem ntu, txij li thaum muaj xwm txheej nws feem ntau tsis tshua muaj kev puas tsuaj.
Cov ntawv kaw los ntawm cov nplais nplaum lossis lub xeev muaj zog yog decrypted rau hauv lub computer. Raws li cov ntaub ntawv tau, nws muaj peev xwm simulate tus cwj pwm ntawm ib lub dav hlau ntawm simulator lossis hauv khoos phis tawm. Koj tuaj yeem muab cov ntaub ntawv no sau ua cov kab ntawv ib txwm siv.
Txawm hais tias txhua txoj kev tiv thaiv kev tiv thaiv, cov ntawv sau davhlau feem ntau muaj kev puas tsuaj thaum sib tsoo. Cov kws tshaj lij decryption yuav tsum rov qab tau cov ntaub ntawv. Piv txwv li, qhov poob qis-los-poob colloidal kev ncua ntawm ferromagnetic hmoov yog thov rau cov kab xev sib nqus. Hmoov sags nyob rau hauv tus ntawm electromagnetic pulses. Qhov tshwm sim yog duab ntawm qhov kaw cov ntaub ntawv khaws tseg lawm.
Cov ntaub ntawv tseem tseem raug khaws tseg los ntawm cov qauv ntawm magneto-optical visualization. Hauv qhov teeb pom kev zoo, ib daim duab ntawm cov kab xev kaw kom pom tseeb. Txawm li cas los xij, ob qho tag nrho ntawm cov hau kev no siv tau rau hauv qhov chaw uas zaj duab xis khaws cov hlau nplaum nyob ntev.
