1. Gwiritsani ntchito zinthu zachilengedwe kuti mudziwe komwe akuchokera

Popanda mapu ndi makampasi ndi zida zina, phunzirani kugwiritsa ntchito zina mwazinthu zachilengedwe kuti mudziwe mayendedwe.

Choyamba, dzuwa ndilo "singano yakumpoto" yodalirika kwambiri.

Tikudziwa kuti dzuŵa limayenda kuchokera kum’maŵa kupita kumadzulo, pamene mthunzi umayenda kuchokera kumadzulo kupita kum’maŵa.Mwachitsanzo, 6 koloko m’maŵa, dzuŵa limatuluka kum’maŵa, ndipo mithunzi ya zinthu zonse imagwera kumadzulo;pa 12 koloko masana, dzuwa lili chifukwa cha kumwera ndipo mthunzi umaloza kumpoto;pa 6 koloko masana, dzuŵa limakhala kumadzulo ndipo mthunzi umaloza kum’maŵa .Choncho, njirayo imatha kutsimikiziridwa mozama ndi mthunzi wa dzuwa ndi zinthu.Monga mwambi umati: "Zotsatira zaposachedwa", gwiritsani ntchito mtengo (ndondomeko yowongoka) kuti ikhale yozungulira pansi, ndikuyika mwala pa vertex A ya mthunzi wamtengo;pafupifupi mphindi 10, ikani chidutswa china pamene vertex ya mthunzi wamtengo isunthira ku B Mwala umagwirizanitsa mfundo ziwiri A ndi B kukhala mzere wowongoka.Mayendedwe a mzere wowongokawu ndi kum'mawa mpaka kumadzulo.Mayendedwe a perpendicular ku mzere wa AB ndi kumpoto ndi kum'mwera.Mapeto ake akuyang’ana ku dzuŵa ndi kum’mwera, ndipo mbali ina yake ndi kumpoto.

Dziwani mayendedwe motengera njira iyi.Kukwera kwa plunger, kuonda kwambiri, kumayang'ana kwambiri pansi, ndipo mthunzi umayenda motalika, ndizomwe zimayendera molondola kwambiri.Makamaka cha m'ma 12 koloko masana.Mwachitsanzo, kutalika kwa mthunzi pa 11:30 ndi 12:30 kumakhala kofanana.Mzere wa ma vertices umangoloza kummawa ndi kumadzulo, ndipo mzere wowongoka wa mzerewu ukhozanso kusonyeza kumpoto ndi kum'mwera molondola.

Dziko lapansi limazungulira madigiri 360 mu maola 24 ndi madigiri 15 mu ola limodzi.Dzanja la ola la wotchi nthawi zonse limatembenuka kawiri mwachangu ngati dzuwa.Potengera mfundo imeneyi, malowa akhoza kuyezedwa ndi wotchi ndi dzuwa.Pa 6 koloko m’mawa, dzuŵa lili kum’mawa ndipo mthunziwo ukuloza kumadzulo.Panthawiyi, lozani dzanja la ola pa ulonda kudzuwa, ndipo "12" pa dial idzaloza kumadzulo.Ngati kuyimba kwasinthidwa madigiri 90, kudzakhala theka 6 koloko, kupanga "3" pa kuyimba.“” ikuyang’ana ku dzuŵa, “12” yaloza kumpoto;pa 12 koloko masana, dzuŵa lili kum’mwera, ndipo 12 amapindidwa pakati kuti “6” pacholembacho ayang’ane ndi dzuŵa, ndipo “12” amalozerabe kumpoto.

Tsimikizirani mayendedwe motsatira njira iyi, poganizira kusiyana kwa nthawi komweko.Nthawi ya Beijing iyenera kusinthidwa kukhala nthawi yakomweko.Kutengera ndi mzere wa kutalika kwa madigiri 120, onjezani ola limodzi ku nthawi ya Beijing pamadigiri 15 aliwonse kum'mawa kwa longitudo, ndikuchotsani ola limodzi pa nthawi ya Beijing pa madigiri 15 aliwonse kumadzulo, yomwe ndi nthawi yakumaloko.Mwachitsanzo, kugwirizanitsa kwa malo a Urumqi ndi 87 madigiri 40 mphindi za kum'mawa kwa longitude, ndiye (120 ° -87 °) ÷ 15 ° = maola 2 ndi mphindi 9, ndipo nthawi ya Beijing kuchotsera maola 2 ndi mphindi 9 ndi nthawi yakomweko ku Urumqi. .
