cross section
(gcide) | cross section \cross section\ v. t.
to create one or a series of cross sections[3] by cutting
(an object) into thin slices.
[PJC] |
cross section
(gcide) | cross section \cross section\ n.
1. a flat plane cutting through a three-dimensional object,
usually at right angles to the longest axis of the object.
[PJC]
2. any visual representation of a cross section[1], showing
the internal structure of the object in the plane of the
cross section; as, the technician prepared a series of MRI
cross sections of the skull.
Note: Different cross sections created by different
techniques may show different aspects of internal
structure. Thus computerized axial tomography using
X-rays shows different structures than are visualized
by MRI.
[PJC]
3. a thin slice of an object made by cutting it transversely;
as, to view a cross section of a bacterium with an
electron microscope after staining the DNA; cross sections
were prepared with a microtome.
[PJC]
4. a representative sample of a complex group; as, the town
contained a cross section of the American population.
[PJC]
5. (Physics) a measure of the probability that a nucleus will
interact in a specified way with a bombarding particle,
expressed as the effective area that the nucleus presents
to the particle; -- called also nuclear cross section.

cross section
(wn) | cross section
n 1: a section created by a plane cutting a solid perpendicular
to its longest axis
2: a sample meant to be representative of a whole population
3: (physics) the probability that a particular interaction (as
capture or ionization) will take place between particles;
measured in barns |
