Rough law energy and measurement of $\bar{F}$-decomposition rough law

By employing function one-direction S-rough sets and rough law generation method based on function S-rough sets,
$\bar{F}$
-decomposition law and
$\bar{F}$
-decomposition rough law are proposed, and the measurement of rough law variation in the process of rough law
$\bar{F}$
-decomposition is researched. The concepts of law energy and attribute
$\bar{f}$
-interference degree are presented, which make the variation of rough law become measurable.
$\bar{f}$
-decomposition law energy characteristic theorem,
$\bar{f}$
-decomposition law energy inequality theorem,
$\bar{F}$
-decomposition rough law energy characteristic theorem, and
$\bar{f}$
-decomposition law energy mean value theorem are presented.
