Sib nqus Compass:

Magnetic compass yog hom compass uas paub tshaj plaws.Nws ua haujlwm raws li tus taw qhia rau "sab qaum teb sib nqus", lub hauv zos sib nqus meridian, vim tias rab koob magnetized ntawm nws lub plawv sib haum nrog cov kab rov tav ntawm lub ntiaj teb magnetic teb.Lub magnetic teb exerts ib tug torque ntawm rab koob, rub lub North kawg los yog ncej ntawm rab koob kwv yees li ntawm lub ntiaj teb sab qaum teb magnetic ncej, thiab rub lwm tus mus rau lub ntiaj teb sab qab teb magnetic ncej.Lub koob yog mounted rau ib tug tsawg-kev sib txhuam pivot point, nyob rau hauv zoo compasses ib lub pob zeb diamond bearing, yog li nws yuav tig tau yooj yim.Thaum lub compass tuav theem, rab koob tig mus txog, tom qab ob peb feeb kom cov oscillations tuag tawm, nws nyob rau hauv nws txoj kev sib npaug.
Hauv kev taw qhia, cov lus qhia ntawm daim duab qhia feem ntau yog qhia nrog rau thaj chaw lossis sab qaum teb tiag tiag, kev taw qhia mus rau Geographical North Ncej, qhov kev sib hloov ntawm lub ntiaj teb.Nyob ntawm qhov twg lub compass nyob rau saum npoo ntawm lub ntiaj teb lub kaum sab xis ntawm qhov tseeb sab qaum teb thiab sab qaum teb sib nqus, hu ua magnetic declination tuaj yeem sib txawv nrog thaj chaw.Lub zos magnetic declination yog muab nyob rau hauv feem ntau maps, tso cai rau daim ntawv qhia mus rau oriented nrog ib tug compass parallel mus rau sab qaum teb.Qhov chaw ntawm lub ntiaj teb cov ncej hlau nplaum maj mam hloov nrog lub sijhawm, uas yog hu ua geomagnetic secular variation.Cov txiaj ntsig ntawm qhov no txhais tau tias daim ntawv qhia nrog cov ntaub ntawv tsis txaus siab zaum kawg yuav tsum tau siv.[9]Ib co magnetic compasss muaj xws li txhais tau tias manually compensate rau lub magnetic declination, kom lub compass qhia tseeb cov lus qhia.

Yuav nrhiav kev taw qhia li cas thaum koj poob?

1. Xaiv peb lub cim tseem ceeb.Cov cim tseem ceeb yuav tsum yog ib yam uas koj tuaj yeem pom thiab pom hauv daim ntawv qhia.Thaum koj tsis paub tias koj nyob qhov twg ntawm daim ntawv qhia, qhov tseem ceeb tshaj plaws yog siv lub compass kom paub cov kev taw qhia, tab sis nws tsis yooj yim los ua qhov no.Kev txheeb xyuas thaj chaw uas tuaj yeem pom ntawm daim ntawv qhia yuav pab nthuav koj lub zeem muag thiab pab koj hloov koj txoj kev taw qhia
2. Teem lub xub taw qhia ntawm thawj txoj kev kos npe.Tsuav yog txoj kev kos npe tsis nyob hauv koj sab qaum teb, rab koob sib nqus yuav deflect.Twist lub dial thiaj li hais tias tus xub taw qhia thiab sab qaum teb kawg ntawm rab koob sib nqus nyob rau hauv ib txoj kab ncaj nraim.Lub sijhawm no, cov kev taw qhia qhia los ntawm lub xub taw qhia yog cov kev taw qhia koj tab tom nrhiav.Nco ntsoov kho qhov sib txawv raws li koj cheeb tsam.
3. Siv daim ntawv qhia nrhiav qhov chaw ntawm txoj kev kos npe.Tso daim ntawv qhia ncaj nraim rau ntawm qhov chaw tiaj tus, thiab tom qab ntawd muab lub compass rau ntawm daim ntawv qhia kom tus xub taw qhia rau sab qaum teb ntawm daim ntawv qhia.Tom ntej no, thawb lub compass nyob rau hauv kev taw qhia ntawm txoj kev kos npe rau ntawm daim ntawv qhia kom txog rau thaum lub ntug ntawm lub compass intersects nrog rau txoj kev kos npe rau.Nyob rau tib lub sijhawm, tus xub taw qhia yuav tsum nyob twj ywm taw rau sab qaum teb.
4. Txiav txim siab koj txoj hauj lwm los ntawm triangulation.Kos ib txoj kab nyob ntawm ntug ntawm lub compass thiab hla koj txoj hauj lwm kwv yees ntawm daim ntawv qhia.Koj yuav tsum kos peb kab tag nrho.Qhov no yog thawj tus.Kos ib txoj kab ntawm ob txoj kev kos npe rau tib txoj kev.Tom qab kos duab, ib daim duab peb sab yog tsim rau ntawm daim ntawv qhia.Thiab koj txoj hauj lwm yog nyob rau hauv daim duab peb sab.Qhov loj ntawm daim duab peb sab nyob ntawm qhov tseeb ntawm koj qhov kev txiav txim siab.Qhov tseeb dua qhov kev txiav txim, qhov me me ntawm daim duab peb sab.Tom qab kev xyaum ntau, koj tuaj yeem ua peb kab sib ntsib ntawm ib qho

Tswv yim:

Koj tuaj yeem tuav ob qhov kawg ntawm daim duab plaub nrog ob txhais tes thiab tuav lub compass pem hauv ntej ntawm koj lub hauv siab.Ua li no, tus ntiv tes xoo yuav yog L-shaped thiab lub luj tshib yuav ntsib ob sab.Thaum sawv ntsug, fim koj lub hom phiaj, khaws koj ob lub qhov muag nyob rau hauv pem hauv ntej, thiab koj lub cev tab tom tig mus rau qhov chaw koj xav siv los sau koj txoj haujlwm.Lub sijhawm no, xav txog tias muaj ib txoj kab ncaj nraim ntawm koj lub cev mus rau lub compass.Txoj kab ncaj nraim hla ntawm lub compass thiab txuas nrog tus taw tes rau hauv txoj kab ncaj nraim.Koj tseem tuaj yeem nias koj tus ntiv tes xoo ntawm koj lub plab kom lub compass tuav kom ruaj khov.Nco ntsoov tsis txhob hnav steel siv buckles lossis lwm yam khoom sib nqus, txwv tsis pub ze rau lub compass yuav ua rau muaj kev cuam tshuam.
Cov txiaj ntsig tau tseeb dua tuaj yeem tau los ntawm kev siv cov khoom nyob ze los txiav txim qhov kev taw qhia.Thaum koj poob rau hauv qhov chaw uas tsis muaj kev siv, nws tsim nyog siv triangulation.
Cia siab rau koj lub compass.Hauv 99.9% ntawm cov neeg mob, lub compass yog qhov tseeb.Ntau qhov chaw zoo li zoo sib xws, yog li kuv tseem ntseeg tias koj lub compass muaj kev ntseeg siab dua.
Txhawm rau txhim kho qhov tseeb, tuav lub compass nyob rau hauv pem hauv ntej ntawm koj thiab saib hauv qab taw tes taw qhia kom pom cov paib txoj kev uas siv tau.
Sab saum toj ntawm lub compass pointer feem ntau yog liab los yog dub.Sab qaum teb kawg feem ntau cim nrog n.Yog tias tsis yog, nco ntsoov siv qhov taw qhia ntawm lub hnub los txiav txim siab qhov kawg yog sab qaum teb kawg.

Peb muaj txhua yam ntawm cov compasses, thov hu rau peb kom paub ntxiv, ua tsaug.
