Among these, a number of works have been carried out on investigation of the crystal chemistry and luminescence properties of compounds having pyrochlore structure [2-3].
Usually the presence of the reflections from the crystallographic planes (111), (331) and (511) is considered as evidence of the pyrochlore structure distinguished form the defect fluorite structure.
The result confirmed that sample c possess cubic pyrochlore structure with space group of Fd-3m (227).

At the same time we explained the curves of infrared absorption analysis of natural black tourmalines at room temperature are simillar despite of their diversification in chemistry component and producing area, and they have high infrared emissivity from the theory point of view.
The chemistry components of tourmalines are different according to their producing area and diggninigs among which the ferric oxide influences the infrared radiation emissivity significantly.
Some academician consider that its crystal structure belonging to c3v result in the emissivity, others consider that the emissivity due to the exsistence of alive bond[8].

The curves of infrared absorption analysis of natural black tourmalines at room temperature are simillar and the absorb peaks are stabilizated despite of their diversification in chemistry component and producing area and difference in thermoelectricity[11].

The first reaction, i.e., the hydrazine decomposition, is a structure insensitive reaction, i.e., is independent of the particles size.
However, the ammonia decomposition is a structure sensitive reaction depending on the average size or diameter of the dispersed active metal.
So, the second reaction, ammonia decomposition, is a structure sensitive reaction depending on the average size or diameter of the dispersed active metal.

The structure of modified polyacrylonitrile fiber was characterized by the means of IR, EA, TG and gravimetric analysis, etc., meanwhile, the preparation conditions as well as adsorption property of the fiber for precious metal ions were researched.
The paper investigated the effect produced by solvent, molar ratio of reagent, reaction time, pH, etc. on reaction products, meanwhile the structure and property of the functional fiber were characterized by the means of IR, EA, TG, gravimetric analysis[8], etc..
Then the treated PANF was heated in DMF solvent for a long time but without dissolving showed all the three kinds of crosslinking agent can make PANF form reticular cross-linked structure.
