A mixture of time dilations and constrictions



Lorentz transform predicts a mixture of time dilations and
constrictions in the primed system. Lorentz second equation
can be transformed into

t' - t = gamma[t(1 - 1/gamma) - x(v/c^2)]

The observer in the unprimed frame knows v and can also
evaluate t and x for various processes that can be registered
in both frames. Then he/she might use the above equation for
determining the sign of the difference t'-t.
A negative x always indicates time CONSTRICTION, t'>t.
A large t and small positive x also indicate t'>t. In
contrast, a large positive x and a small t guarantee time
DILATION, t'<t. Precise calculations are also possible,
provided the observer can determine t and x with precision.
Processes characterized only by time dilation are
traditionally called "stationary". I would be grateful if
someone could give the definition of such stationary
processes and then describe some particular one.
