longitude    音标拼音: [l'ɑndʒət,ud]
n. 经度,经线

经度,经线

longitude
经度

longitude
n 1: the angular distance between a point on any meridian and
the prime meridian at Greenwich

Longitude \Lon"gi*tude\, n. [F., fr. L. longitudo, fr. longus
long.]
1. Length; measure or distance along the longest line; --
distinguished from {breadth} or {thickness}; as, the
longitude of a room; rare now, except in a humorous sense.
--Sir H. Wotton.
[1913 Webster]

The longitude of their cloaks. --Sir. W.
Scott.
[1913 Webster]

Mine [shadow] spindling into longitude immense.
--Cowper.
[1913 Webster]

2. (Geog.) The arc or portion of the equator intersected
between the meridian of a given place and the meridian of
some other place from which longitude is reckoned, as from
Greenwich, England, or sometimes from the capital of a
country, as from Washington or Paris. The longitude of a
place is expressed either in degrees or in time; as, that
of New York is 74[deg] or 4 h. 56 min. west of Greenwich.
[1913 Webster]

3. (Astron.) The distance in degrees, reckoned from the
vernal equinox, on the ecliptic, to a circle at right
angles to the ecliptic passing through the heavenly body
whose longitude is designated; as, the longitude of
Capella is 79[deg].
[1913 Webster]

{Geocentric longitude} (Astron.), the longitude of a heavenly
body as seen from the earth.

{Heliocentric longitude}, the longitude of a heavenly body,
as seen from the sun's center.

{Longitude stars}, certain stars whose position is known, and
the data in regard to which are used in observations for
finding the longitude, as by lunar distances.
[1913 Webster]


Refraction \Re*frac"tion\ (r?*fr?k"sh?n), n. [F. r['e]fraction.]
1. The act of refracting, or the state of being refracted.
[1913 Webster]

2. The change in the direction of ray of light, heat, or the
like, when it enters obliquely a medium of a different
density from that through which it has previously moved.
[1913 Webster]

Refraction out of the rarer medium into the denser,
is made towards the perpendicular. --Sir I.
Newton.
[1913 Webster]

3. (Astron.)
(a) The change in the direction of a ray of light, and,
consequently, in the apparent position of a heavenly
body from which it emanates, arising from its passage
through the earth's atmosphere; -- hence distinguished
as atmospheric refraction, or astronomical refraction.
(b) The correction which is to be deducted from the
apparent altitude of a heavenly body on account of
atmospheric refraction, in order to obtain the true
altitude.
[1913 Webster]

{Angle of refraction} (Opt.), the angle which a refracted ray
makes with the perpendicular to the surface separating the
two media traversed by the ray.

{Conical refraction} (Opt.), the refraction of a ray of light
into an infinite number of rays, forming a hollow cone.
This occurs when a ray of light is passed through crystals
of some substances, under certain circumstances. Conical
refraction is of two kinds; external conical refraction,
in which the ray issues from the crystal in the form of a
cone, the vertex of which is at the point of emergence;
and internal conical refraction, in which the ray is
changed into the form of a cone on entering the crystal,
from which it issues in the form of a hollow cylinder.
This singular phenomenon was first discovered by Sir W. R.
Hamilton by mathematical reasoning alone, unaided by
experiment.

{Differential refraction} (Astron.), the change of the
apparent place of one object relative to a second object
near it, due to refraction; also, the correction required
to be made to the observed relative places of the two
bodies.

{Double refraction} (Opt.), the refraction of light in two
directions, which produces two distinct images. The power
of double refraction is possessed by all crystals except
those of the isometric system. A uniaxial crystal is said
to be optically positive (like quartz), or optically
negative (like calcite), or to have positive, or negative,
double refraction, according as the optic axis is the axis
of least or greatest elasticity for light; a biaxial
crystal is similarly designated when the same relation
holds for the acute bisectrix.

{Index of refraction}. See under {Index}.

{Refraction circle} (Opt.), an instrument provided with a
graduated circle for the measurement of refraction.

{Refraction of latitude}, {longitude}, {declination}, {right
ascension}, etc., the change in the apparent latitude,
longitude, etc., of a heavenly body, due to the effect of
atmospheric refraction.

{Terrestrial refraction}, the change in the apparent altitude
of a distant point on or near the earth's surface, as the
top of a mountain, arising from the passage of light from
it to the eye through atmospheric strata of varying
density.
[1913 Webster]


Heliocentric \He`li*o*cen"tric\
(h[=e]`l[i^]*[-o]*s[e^]n"tr[i^]k), Heliocentrical
\He`li*o*cen"tric"al\ (h[=e]`l[i^]*[-o]*s[e^]n"tr[i^]*kal), a.
[Helio- centric, centrical: cf. F. h['e]liocentrique.]
(Astron.)
pertaining to the sun's center, or appearing to be seen from
it; having, or relating to, the sun as a center; -- opposed
to {geocentrical}.
[1913 Webster]

{Heliocentric parallax}. See under {Parallax}.

{Heliocentric place}, {latitude}, {longitude}, etc. (of a
heavenly body), the direction, latitude, longitude, etc.,
of the body as viewed from the sun.
[1913 Webster]
