Sequence analysis and phylogenetical study showed that this cDNA contained 778 nucleotides, with a 627 bp open reading frame flanked with a 44 bp 5' UTR and a 107 bp 3' UTR. The encoded 208 amino acids housefly Attacin shared a high similarity of 50%~70% with that of the other dipterous insects. In addition, the phylogenetical analysis also indicated that the Attacin from housefly was in the same branch with those of other species, suggesting that they come from the same ancestor.

Study on the driving forces of land use/cover temporal-spatial change. On the basis of the systematical study on natural and social-ecomic factors including climate, population, technology and affluence status etc. during the past 50 years in this area, the multivariate statistics simulation models of LUCC were developed for two periods of 1950's-1980's and 1986-2000 respectively. Then, the Thiesson polygon method was used to the spatial allocation of soci-economic factors, thereby the spatial relationship between land use degree change and socieconomic factor variation was detected within GIS. Based on the analysis of the integrative characters in different geographical divisions, the electivity index was employed to describe the possible impacts of the natural landscape structure on spatial differentiation of land use transition. At last, correlation analysis between major roads and the distribution of land use change was made.

For supercooling directional solidification, ideal directional microstructure can be obtained only within the supercooling range 63～83K and 127～170K. These two supercooling ranges just corresponds to the supercooling for developed equiaxial dendrites in ordinary supercooling solidification.

6对于深过冷定向凝固来说，只有在63～83K的低过冷度范围和127～170K的中过冷度范围才能获得理想的定向生长组织，而这两个过冷度范围正好对应于深过冷熔体凝固组织为发达的等轴枝晶的过冷度范围，这种组织的相似性似乎与过冷度一样具有遗传性。
