The second part discusses the operations on base?cover countably paracompact spaces,including subspaces of the base?cover countably paracompact space and sum spaces andproduct spaces of base?cover countably paracompact spaces, and we mainly got the followingresults:2.

In this paper,we study the Friedrichs extension of the minimal operator of regular order differential operators in direct sum spaces by the basic theory of first-order systems of differential equation and their relationship to general n-th order quasi-differential expressions,and give the boundary conditions of Friedrichs extension.

In this paper we investigate the characterization of self-adjoint domains of symmetric differential operators with interior singular points in the direct sum spaces.

This note gives some counterexamples for the generalized pre-capacity and capacity to show that (a) a generalized pre-capacity in a CC-Harmonic space may be neither a generalized capacity nor a CC-capacity and (b) a capacity may have not the right continuity with respect to compect sets.

Therefore,this paper tries to improve the disordered space system with another connective harmonic space,on the basis of the existing theory of the main space.

Time and space is surface layer effect of the packing design.

Its most outstanding character is the union of theory and practice,the union of time and space,the u-nion of individual and collective.
