1.The theoretical analysis indicates that the main factors of cover-shelter properties of fabrics are cover factor of fabrics,fabric thicknesss,optical reflectance and absorbance of yarn.With a combination of distances and luminaces,512 experiments were made to find out the relationship between the least distinguishable distance and reflectance coefficient.
2.In this paper,Zeolite NaY treated from kaolinite continued to be treated,such as ground in the agate mortar,dried in 120℃ for an hour,damped in the surroundings of supersaturated calcium chloride solution(room temperature from 20℃ to 30℃) for 16 to 24 hours,The treated Zeolite NaY was determined by X-ray diffractometer,the Composition,crystallinity,cell parameter and ratio of silicate to aluminium of Zeolite NaY was analyzed.
