| 1 | Microstructure evolution of Al-Zn-Mg-Cu-Zr alloy during hot deformation显示文摘Compression tests of the Al-Zn-Mg-Cu-Zr(7055) alloy were performed at various strains and temperatures from 300 to 450℃ under a constant strain rate between 10-2 s-1 and 1 s-1.Microstructures during hot deformation were studied by transmission electron microscopy(TEM).Dislocation density,dislocation cells and subgrains of the deformed samples were investigated in detail and compared to make a better understanding of the microstructure evolution.The results showed that stress-strain curves under the experimental conditions belonged to the type of dynamic recovery.When the alloy deformed at various strains and 300℃,the microstructure underwent a process of disordered dislocations to cell structure,subgrain structure and subgrain coarsening.With the temperature increasing,subgrains grew and dislocation density in the interior decreased at a strain rate of 1 s-1.At the temperature of 350℃,the average diameter of subgrains decreased,sub-boundaries broadened and dislocation density in the interior decreased when the strain rate was increased.The deformed samples of 7055 alloy had smaller subgrains than that of 7005 alloy at the same compression condition because of high alloy content. | YAN Liangming,SHEN Jian,LI Zhoubing,LI Junpeng,and YAN Xiaodong General Research Institute for Nonferrous Metals,Beijing 100088,China | 2010 | Rare Metals2010，29，4： | 4 |
| 2 | Genome-wide mapping of conserved microRNAs and their host transcripts in Tribolium castaneum显示文摘MicroRNAs (miRNAs) are endogenous 22-nt RNAs,which play important regulatory roles by post-transcriptional gene silencing. A computational strategy has been developed for the identification of conserved miRNAs based on features of known metazoan miRNAs in red flour beetle (Tribolium castaneum),which is regarded as one of the major laboratory models of arthropods. Among 118 putative miRNAs,47% and 53% of the predicted miRNAs from the red flour beetle are harbored by known protein-coding genes (intronic) and genes located outside (intergenic miRNA),respectively. There are 31 intronic miRNAs in the same transcriptional orientation as the host genes,which may share RNA polymerase Ⅱ and spliceosomal machinery with their host genes for their biogenesis. A hypothetical feed-back model has been proposed based on the analysis of the relationship between intronic miRNAs and their host genes in the develop-ment of red flour beetle. | Qibin Luo Qing Zhoub Xiaomin Yu Hongbin Lin Songnian Hu Jun Yu | 2008 | Journal of Genetics and Genomics2008，35，6： | 3 |
