Structure Determination by X-ray Crystallography
Once the crys- tallographic axes are chosen, a parametral plane may be defined
and any other plane described in terms of three numbers h, k, and l. It is an
experimental fact that, in crystals, if the parametral plane is designated by integral
...

Domain of copositivity of a parametral matrix For the discussion of this section A(
h) will denote a real parametral r.r matrix, having the properties, we specify in the
following definition. DEFINITION 4.1 A real parametral r . r matrix is proper ...

A Treatise on Crystallography
It follows, however, from the law of rational indices that the parameters obtained
by taking a new parametral plane are simple commensurable multiples, fractional
or integral, of the parameters given by the first plane. So far no limitation has ...

Symmetry of Crystals and Molecules
Thus, the line can be specified by the equation X a + Y b = 1 (2.2) Equation (2.2)
is the intercept form of the equation of the line AB, which will be chosen as a
reference or parametral line; the extension to three-dimensions will be discussed

parametral or unit plane, and the three lengths a, b and c are called the
parameters of the crystal ; it must be remembered that these lengths are merely
relative, and are constant only as regards their ratios to one another and not in
absolute ...

Again, however, this description -which rests not only on the actual spatial
separation of the parametral layers but also on a lack of dynam ism which is the
general result - depends on what we mean by time. Nauck, for example, criticised

Crystallization Process Systems
If, for example, three crystallographic axes have been decided upon, a plane that
is inclined to all three axes is chosen as the standard or parametral plane. The
intercepts X, Y, Z of this plane on the axes x, y, and z are called parameters a, ...
The parametral plane of the system will be one parallel to the plane C, and will
obviously intersect with the axes with equal parameters. Such an axial system,
therefore, will be represented by the expression — f = i = c; 1, 1, 1, in which the
only ...
