Using fuzzy set theory, the concept of a fuzzy power lattice is introduced, some properties of the fuzzy power lattice and its fuzzy ideal are obtained, some results of lattice are generalized.

In the fourth chapter, we introduce the lattice, the ideal and prove the Chinese remainder theorem in the distributive lattice on which we design a safe communication scheme.
There is a direct relation between the color of ideal crystals (including sapphire) and the varieties and contents of the trace transition metal ions occupying their lattice.
