Usage in Quasicrystal, Liquid and Other Disordered Systems
The coordination number of systems with disorder cannot be precisely defined.
The first coordination number can be defined using the radial distribution function
where is the rightmost position starting from whereon is approximately zero, is the first minimum. Therefore, it is the area under the first peak of .
The second coordination number is defined similarly:
Alternative definitions for the coordination number can be found in literature, but in essence the main idea is the same. One of those definition are as follows: Denote as the position of the first peak,
The first coordination shell is the spherical shell with radius between to around the central particle under investigation.

Famous quotes containing the words usage, liquid, disordered and/or systems:
“Girls who put out are tramps. Girls who don’t are ladies. This is, however, a rather archaic usage of the word. Should one of you boys happen upon a girl who doesn’t put out, do not jump to the conclusion that you have found a lady. What you have probably found is a lesbian.”
—Fran Lebowitz (b. 1951)
“What slender Youth bedew’d with liquid odours
Courts thee on Roses in some pleasant Cave,”
—Horace [Quintus Horatius Flaccus] (65–8)
“The original of the picture you inclose, and which I return, was taken from life, and is, I think, a very true one; though my wife, and many others, do not. My impression is that their objection arises from the disordered condition of the hair.”
—Abraham Lincoln (1809–1865)
“Not out of those, on whom systems of education have exhausted their culture, comes the helpful giant to destroy the old or to build the new, but out of unhandselled savage nature, out of terrible Druids and Berserkirs, come at last Alfred and Shakespeare.”
—Ralph Waldo Emerson (1803–1882)
