The concept of fuzzy homomorphism between two near-ring was defined.

The paper defined two radicals R 0 and R c for near-rings and proved some poperties of these radicals.

The commutative theorem characterized by an associative ring, presented in document 1 noted by Guo Huaguang is extended to the formation of the left near ring with partition law.

This paper discusses the basic properties, ideals and quotients of the near rings which meet distributive law, and some important theovems of ring theories were extended into near rings.

The algebra systemquasi ring has been further studied by using the quasi group.

In this paper,the author establishes a kind of special ring——the quasi ring by using quasi group, then studies its characteristics and structure, at the same time, obtains a series of results about quasi group.

The semi-physical simulation environment system of vehicle cabin, which is produced by taking a test room as the simulation environment of vehicle crew cabin and balance subsystem as the formaldehyde generation device, is used to study the photo-catalytic degradation efficiency of formaldehyde under different conditions.
