不可算名詞
(meteorology)
In
a
system
of
moist
air,
the
ratio
of
the
mass
of
water
vapor
present
to
the
volume
occupied
by
the
mixture,
that
is,
the
density
of
the
water
vapor
component.
Absolute
humidity
is
usually
expressed
in
grams
of
water
vapor
per
cubic
meter
or,
in
engineering
practice,
in
grains
per
cubic
foot.
Because
this
measure
of
atmospheric
humidity
is
not
conservative
with
respect
to
adiabatic
expansion
or
compression,
it
is
not
commonly
used
by
meteorologists.
(Also
called
vapor
concentration
and
vapor
density).
See
relative
humidity.
