Qhov inscription "-1,3%" txhais li cas ntawm daim ntawv nplaum nyob rau hauv lub hood ntawm lub tsheb

Cov tuam txhab tsheb tso cov ntawv nplaum nrog qee qhov tseem ceeb hauv ntau qhov chaw hauv qab lub hood ntawm lub tsheb. Cov ntaub ntawv ntawm lawv yog qhov tseem ceeb, txawm hais tias tsis yog txhua tus neeg saib xyuas nws. Xav txog cov ntawv nplaum uas cov tuam txhab muab tso rau ntawm lub teeb taub hau.

Daim ntawv nplaum zoo li cas?

Daim ntawv nplaum nyob rau hauv nqe lus nug zoo li me me dawb los yog daj duab plaub. Nws schematically depicts lub teeb taub hau thiab qhia ib tug xov tooj raws li ib tug feem pua, feem ntau 1,3%. Muaj tsawg zaus, tej zaum yuav tsis muaj daim ntawv nplaum, tom qab ntawd ib lub thwj uas muaj tib tus lej tuaj yeem pom ntawm lub cev yas ntawm lub teeb taub hau.

Yuav ua li cas decipher inscription ntawm daim ntawv nplaum

Tus lej ntawm daim ntawv nplaum, nyob ntawm qhov tsim ntawm lub tsheb optics, tuaj yeem sib txawv ntawm 1-1,5%. Qhov kev xaiv no txiav txim siab qhov txo qis ntawm lub teeb taub hau thaum lub tshuab tsis thauj khoom.

Cov tsheb niaj hnub muaj cov cuab yeej kho kom haum uas tso cai rau koj los kho lub teeb taub hau nyob ntawm qhov xav tau ntawm tus neeg tsav tsheb, qhov xwm txheej ntawm txoj kev thiab lwm yam kev mob sab nraud. Yog li, piv txwv li, yog tias koj thauj tag nrho lub cev ntawm lub tsheb nrog ib yam dab tsi hnyav, pem hauv ntej ntawm lub tsheb yuav raug tsa, thiab lub teeb taws yuav tsis ci ntawm txoj kev, tab sis nce. Lub corrector tso cai rau koj hloov lub kaum sab xis ntawm lub nqaj kom rov qab pom qhov qub.

Qhov taw qhia ntawm 1,3% txhais tau hais tias yog tias tus kho qhov ntsuas tau teeb tsa rau xoom, theem ntawm lub teeb lub teeb yuav txo tau 13 hli ib 1 meter.

Yuav siv cov ntaub ntawv los ntawm daim nplaum li cas

Feem ntau, cov tswv tsheb tau ntsib nrog qhov tseeb tias lub teeb taws teeb tsis zoo: txoj kev tsis pom kev, thiab cov neeg tsav tsheb ntawm lawv tuaj yeem ua rau dig muag txawm tias muaj kab teeb qis. Cov teeb meem no raug tshem tawm los ntawm kev teeb tsa kom raug ntawm lub hauv ntej optics. Tag nrho cov ntsiab lus ntawm cov txheej txheem zoo li no tau piav qhia meej hauv phau ntawv qhia rau lub tshuab tshwj xeeb. Rau kev teeb tsa tus kheej, cov ntaub ntawv los ntawm daim ntawv nplaum yuav txaus.

Koj tuaj yeem tshawb xyuas qhov ua tau zoo ntawm lub teeb taub hau thiab kho kom raug raws li hauv qab no.

1. Ua ntej tshaj plaws, lub tsheb yuav tsum tau npaj: tshem tawm txhua yam ntawm lub cev, tshwj xeeb tshaj yog cov hnyav, kho lub log tsheb siab, sau cov roj tank. Tsis tas li ntawd, koj tuaj yeem tshawb xyuas qhov xwm txheej ntawm kev ncua thiab kev poob siab absorbers. Tag nrho cov no yuav tso cai kho qhov "zero" theem ntawm lub teeb beam, los ntawm qhov kev suav rov qab yuav ua.
2. Lub tshuab npaj tau nruab kom qhov kev ncua deb ntawm lub teeb taub hau mus rau phab ntsa lossis lwm qhov chaw ntsug yog 10 meters. Qhov no yog qhov nruab nrab pom zoo nyob deb. Qee cov neeg tsim khoom pom zoo kom tig mus rau 7,5 lossis 3 meters, qhov no tuaj yeem qhia meej hauv phau ntawv tsheb.
3. Txhawm rau kom yooj yim, nws tsim nyog ua cov cim rau ntawm phab ntsa: kos qhov nruab nrab ntawm txhua kab teeb ntawm lub teeb ntawm lub taub hau thiab qhov nruab nrab ntawm lub tsheb.
4. Yog tias lub teeb taub hau raug teeb tsa kom raug, tom qab ntawd nrog daim ntawv nyeem ntawv ntawm 1,3% ntawm qhov deb ntawm 10 meters, qhov txwv sab saud ntawm lub teeb ntawm phab ntsa yuav yog 13 centimeters qis dua lub teeb ci (filament hauv lub taub hau).
5. Qhov kev sim no zoo tshaj plaws thaum hmo ntuj thiab huab cua zoo.

Nws yog ib qho tseem ceeb uas yuav tau xyuas qhov kev ua haujlwm kom raug ntawm lub teeb taub hau ib ntus, vim tias cov teeb tsa mus yuam kev thaum lub sijhawm ua haujlwm ntawm lub tsheb. Nws yog txaus los ua qhov no ib xyoos ib zaug lossis tsawg dua yog tias cov qij tsis tau hloov pauv (reflectors yuav mus yuam kev). Txoj kev yooj yim tshaj plaws los kuaj xyuas hauv lub tsheb pabcuam yog tus txheej txheem thiab pheej yig.

Tsis txhob hnov ​​​​qab txog qhov teeb tsa kom raug ntawm lub teeb taub hau: thaum tsav tsheb thaum hmo ntuj, cov tshuaj tiv thaiv ceev ntawm tus neeg tsav tsheb tseem ceeb heev. Kev hloov kho tsis raug teeb pom kev zoo yuav tsis pom qhov teeb meem hauv lub sijhawm, uas yuav ua rau muaj kev sib tsoo.
