Basic paub txog compass:
1. Nkag siab txog cov qauv ntawm lub compass.Txawm hais tias tus tsim ntawm lub compass txawv heev, lawv txhua tus muaj ib yam dab tsi zoo sib xws.Txhua lub compass muaj cov koob magnetic taw rau lub ntiaj teb magnetic teb.Qhov yooj yim tshaj plaws teb compass tseem hu ua base compass.Lub hauv paus ntawm lub compass no yog raws li nram no:
Lub hauv paus phaj hais txog cov yas chassis inlaid nrog lub ntsuas ntsuas ntsuas.
Lub xub taw qhia yog hais txog tus xub qhia txog kev taw qhia ntawm lub hauv paus phaj, uas feem ntau yog tawm tsam rau cov kev taw qhia ntawm tus tuav lub compass.
Compass npog yog hais txog cov yas puag ncig lub plhaub uas muaj lub compass thiab magnetic needle.
Lub dial yog hais txog qhov ntsuas qhov taw qhia ntawm 360 degrees nyob ib ncig ntawm lub compass npog thiab tuaj yeem tig los ntawm tes.
Magnetic needle yog hais txog tus pointer rotating nyob rau hauv lub compass npog.
Lub xub taw qhia yog hais txog tus pointer uas tsis yog sib nqus nyob rau hauv lub compass npog.
Txoj kab kev taw qhia yog hais txog kab sib npaug mus rau lub xub taw qhia hauv lub npog npog.
2. tuav lub compass nyob rau hauv txoj kev.Muab lub compass ca rau ntawm koj xib teg thiab koj xib teg ntawm koj lub hauv siab.Nov yog txoj hauv kev los tuav lub compass thaum sab nraum zoov.Yog tias koj xav xa mus rau daim ntawv qhia tib lub sijhawm, muab lub compass ca rau ntawm daim ntawv qhia kom cov txiaj ntsig yuav raug ntau dua.
3. Txheeb xyuas qhov kev taw qhia koj tab tom ntsib.Yog tias koj xav taw qhia kom raug, koj yuav tsum xub qhia meej cov lus qhia nyob rau hauv pem hauv ntej ntawm koj.Tshawb xyuas lub koob magnetic ntawm lub compass.Lub koob hlau nplaum yuav tsis thim rov qab thiab tawm mus tsuas yog thaum taw qhia rau sab qaum teb. Tig lub dial kom txog thaum lub xub taw qhia thiab rab koob sib nqus nyob rau hauv kab, thiab tom qab ntawd taw tes rau sab qaum teb ua ke, yog li cov xub taw qhia yuav qhia koj cov kev taw qhia pem hauv ntej. ntawm koj.Yog hais tias lub xub taw qhia nyob nruab nrab ntawm sab qaum teb thiab sab hnub tuaj, koj tab tom tig mus rau sab qaum teb sab hnub tuaj.Nrhiav qhov taw tes uas taw qhia xub raws li tus hu.Yog tias koj xav tau cov txiaj ntsig tseeb dua, koj tuaj yeem ua tib zoo xyuas qhov ntsuas ntawm lub compass.Yog hais tias tus taw tes xub taw qhia rau 23 ntawm lub dial, cov kev taw qhia nyob rau hauv pem hauv ntej ntawm koj yog 23 degrees sab qaum teb los ntawm East.
4. Nkag siab qhov sib txawv ntawm sab qaum teb hauv kev nkag siab ntawm kev taw qhia thiab sab qaum teb ntawm rab koob sib nqus.Txawm hais tias ob lub ntsiab lus ntawm "North" yog qhov yooj yim kom tsis meej pem, kuv ntseeg tias koj tuaj yeem paub qhov kev paub yooj yim no sai sai.Yog tias koj xav siv lub compass kom raug, koj yuav tsum nkag siab lub tswv yim no.Qhov tseeb sab qaum teb los yog daim ntawv qhia sab qaum teb yog hais txog qhov chaw uas tag nrho cov meridians ntawm daim ntawv qhia converge ntawm North Ncej.Txhua daim ntawv qhia yog tib yam.Sab qaum teb yog saum daim ntawv qhia.Txawm li cas los xij, vim qhov sib txawv me me ntawm cov hlau nplaum, cov kev taw qhia ntawm lub compass yuav tsis yog North tiag tiag, tab sis lub npe hu ua magnetic needle north.
Qhov sib txawv ntawm sab qaum teb ntawm rab koob sib nqus yog tshwm sim los ntawm qhov sib txawv ntawm qhov sib nqus, uas yog li 11 degrees deb ntawm lub ntiaj teb lub hauv paus axis.Ua li no, yuav muaj 20 degree sib txawv ntawm sab qaum teb tiag tiag ntawm qee qhov chaw thiab sab qaum teb ntawm rab koob sib nqus.Yuav kom nyeem tau cov kev taw qhia ntawm lub compass kom raug, lub zog ntawm magnetic teb deviation yuav tsum tau coj mus rau hauv tus account.Qhov loj ntawm qhov cuam tshuam txawv nrog qhov chaw.
Qee zaum qhov txawv yog ntau txhiab mais.Qhov ntawm lub compass ib zaug zoo li tsis tseem ceeb, tab sis tom qab taug kev ib mais lossis ob, qhov sib txawv yuav tshwm sim.Koj tuaj yeem xav txog yuav ua li cas yog tias koj nyob deb tshaj kaum lossis nees nkaum mais deb.Yog li ntawd, qhov sib txawv ntawm magnetic teb yuav tsum tau coj mus rau hauv tus account thaum nyeem ntawv.
5. Kawm kom kho qhov sib txawv.Deviation yog hais txog qhov sib txawv ntawm qhov tseeb sab qaum teb ntawm daim ntawv qhia thiab North taw qhia los ntawm lub compass tshwm sim los ntawm cov hlau nplaum.Koj tuaj yeem kho lub compass kom qhov kev taw qhia tau raug ntau dua.Cov txheej txheem yog nce lossis txo tus lej kom tsim nyog raws li kev ntsuas sib txawv (txawm hais tias nrog kev pab ntawm daim ntawv qhia lossis tsuas yog cia siab rau Compass) thiab cov haujlwm sib txawv (hauv cheeb tsam sab hnub tuaj lossis sab hnub poob).Nrhiav seb qhov twg qhov xoom sib txawv ntawm koj lub tebchaws yog, thiab mam li xam seb koj yuav tsum tau ntxiv lossis rho tawm raws li koj txoj haujlwm tshwj xeeb.Piv txwv li, yog tias koj siv lub compass nyob rau sab hnub poob cheeb tsam, koj yuav tsum tau ntxiv qhov tsim nyog degree rau kev nyeem ntawv kom pom qhov tseeb taw qhia ntawm daim ntawv qhia.Yog tias koj nyob rau thaj tsam sab hnub tuaj, rho tawm cov degrees kom tsim nyog.
