In this paper, the structures of five topologies on product spaces are discussed. A structural representation of the inductive limit topology is given by means of the Hamel base of a linear space, and another structural representation of the induced topology is given as Well. Then the relationships between the five topologies are discussed. Among these topologies the one- ordering topology is put forward by the author himself. In accordance with the mutual relationships between the five topologies on pro duct spaces, some properties concerning these topologies are discussed in this pader. The author also introduces the concept of maximal compatible subspace with respect to a topology on a linear space, which becomes a topological linear spaece, and the maximal compatible subsbaces are given to the box topology, the one-ordering topology and the induced topology on propuct spaces respectively, The completeness of the maximal compatible subspace with respect to the three topologies on the product space is given in a unified form. In this paper, the relationships between the normed topology, the projective limit topology, and the inductive limit topology on the Limit spaces, and also the relationships of the relative topologies of these topologies on the subspaces of the limit spaces are discusseo with theaid of structure. On the other hand, by taking advantage of the discussion on the completeness of the maximal compatible subspace with respect to the one-ordering topology, the proof of the sufficiency of the condition in the main proposition (4.1) cf [8] is much simplified.

Let L be a CD-lattice, then L has a subset M consisting of non-zero irreduciable elements of L such that, each element α of L can be expressed as a union of elements of M which are less than or equal to α.Theorem 6. Let L be a CD-lattice and δ a topology on L, then (L,δ) is a generalized topological molecular lattice [2] while the set of molecules coinsides with the set M consisting of all non-zero irreduciable elements of L.The above theorem shows that the theory of generalized topological molecular lattices is a proper generalization of that of L-fuzzy topology.

Some fundamental results such as the fuzzy unit intezval, Q-nei-ghborhood structure and algebraic properties of union-preserving maps in lattices are collected. A pointwise characterization of fuzzy complete regularity is yielded by means of the Q- neighborhood structures and some algebraic properties of certain class of maps...

A pointwise characterization of fuzzy complete regularity is yielded by means of the Q- neighborhood structures and some algebraic properties of certain class of maps in lattices. The Weil theorem on fuzzy uniformity and the general imbedding theorem in the fuzzy basic cube are established. As applications of the imbedding theorem, a fuzzy version of the well-known Urysohn metrizable theorem and the general theory of the fuzzy Stone-Cech compactification are given,
