The sonic plane forms a " choke point " that enables the lead shock, and reaction zone, to travel at a constant velocity, undisturbed by the expansion of gases in the rarefaction region beyond the CJ plane.

Rarefaction analysis assumes that the individuals in an environment are randomly distributed, the sample size is sufficiently large, that the samples are taxonomically similar, and that all of the samples have been performed in the same manner.
43.
"' P-waves "'are a type of compressions and rarefactions or "'primary wave "', as it has the highest velocity and is therefore the first wave to be recorded.
44.
A complete cycle, or one complete soundwave, consists of an increase of pressure in the air, a subsequent decrease of pressure so that the pressure is back to normal, and a following decrease in air pressure called rarefaction.
45.
In a paper criticizing many methods of assaying biodiversity, Stuart Hurlbert refined the problem that he saw with Sanders'rarefaction method, that it overestimated the number of species based on sample size, and attempted to refine his methods.
46.
I do not know if you can produce a liquid-gas mixture by sending a shock wave through water ( no rarefaction, just shock ); but you can definitely bring the water above the liquid-gas critical point.
47.
""'Etymology " "'is an audio source library recorded in 1995 by royalty free, and Rarefaction stated that they are free for use in " musical or multimedia project [ s ] ".
48.
For instance, our historical understanding about " sound ", " light " and " heat " have today been reduced to " wave compressions and rarefactions ", " electromagnetic waves ", and " molecular kinetic energy ", respectively.
49.
Aristotle ( 384-322 BC ) understood that sound consisted of compressions and rarefactions of air which " falls upon and strikes the air which is next to it . . . ", a very good expression of the nature of wave motion.
50.
Most commonly, the number of species is sampled to predict the number of genera in a particular community; similar techniques had been used to determine this level of diversity in studies several years before Sanders quantified his individual to species determination of rarefaction.
