Txhua degree ntawm latitude yog kwv yees li 69mi ua (111 km) sib nrug. Qhov ntau yam txawv (vim lub ntiaj teb me ntsis ellipsoid duab) los ntawm 68.703 mais (110.567 km) ntawm kab zauv mus rau 69.407 (111.699 km) ntawm tus ncej. Qhov no yooj yim vim hais tias txhua feeb (1/60th ntawm ib degree) yog kwv yees li ib mais [nautical] mais.
Ntawm no, qhov degree ntawm latitude yog dab tsi?
Latitude yog qhov ntsuas ntawm qhov deb ntawm sab qaum teb lossis sab qab teb ntawm Equator. Txhua qhov sib npaug ntsuas ib qho degree sab qaum teb lossis sab qab teb ntawm Equator, nrog 90 qib sab qaum teb ntawm Equator thiab 90 qib sab qab teb ntawm Equator. Cov latitude ntawm North Ncej yog 90 qib N, thiab cov latitude ntawm South Pole yog 90 qib S.
Ib yam li ntawd, ntev npaum li cas ib feeb ntawm latitude? Ib feeb ntawm latitude sib npaug ib nautical mais thiab degrees ntawm latitude yog 60 nm sib nrug. Qhov kev ncua deb ntawm degrees ntawm longitude tsis tas mus li vim hais tias lawv converge ntawm tus ncej.
Ib yam li ntawd, pes tsawg meters nyob rau hauv ib tug degree ntawm latitude?
Niaj hnub no peb paub tias ib feeb ntawm qhov nruab nrab degree ntawm latitude yog 1,852 meters.
Qhov degree ntawm longitude loj npaum li cas?
A degree ntawm longitude yog qhov dav tshaj plaws ntawm txoj kab nruab nrab nrog qhov kev ncua deb ntawm 69.172 mais (111.321 mais). Qhov kev ncua deb maj mam txo mus rau xoom thaum lawv ntsib ntawm tus ncej. Hauv 40 qib sab qaum teb los yog sab qab teb, qhov kev ncua deb ntawm a degree ntawm longitude yog 53 mais (85 km).

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Qhov sib npaug sib npaug rau qhov nruab nrab ntawm h2so4 los ntawm Koh yog dab tsi?
Hauv daim vis dis aus no peb yuav sib npaug ntawm qhov sib npaug KOH + H2SO4 = K2SO4 + H2O thiab muab cov coefficients raug rau txhua qhov sib xyaw. Txhawm rau sib npaug KOH + H2SO4 = K2SO4 + H2O koj yuav tsum nco ntsoov suav tag nrho cov atoms ntawm txhua sab ntawm cov tshuaj sib npaug
Puas yog txhua qhov sib npaug sib npaug sib npaug?
Thawj qhov sib npaug sib npaug yog qhov tseeb yog tias nws muaj kev txuag kom muaj nuj nqis. Piv txwv li, qhov sib npaug sib cais yeej ib txwm muaj tseeb, txij li lub ntsiab lus lawv yog ntawm daim ntawv: M(y) + N(t) = 0, yog li ϕ(t, y) = A(y) + B(t) yog a khaws cia kom muaj nuj nqis
Nws puas yuav ua rau pom qhov sib npaug ntawm kab sib npaug mus rau ib kab thiab los ntawm ib qho taw tes ntawm kab?
Qhov sib npaug ntawm ib kab uas yog parallel lossis perpendicular rau ib kab? Cov lus teb tau: Cov nqes hav ntawm cov kab sib npaug sib npaug. Hloov txoj kab nqes paub thiab cov kev sib koom ua ke ntawm ib qho taw tes ntawm lwm txoj kab rau hauv daim ntawv point-slope kom pom qhov sib npaug ntawm kab sib npaug
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
