Genetic analysis and molecular mapping of a presenescing leaf gene psll in rice （Oryza sativa L.）

A rice psl1 （presenescing leaf） mutant was obtained from a japonica variety Zhonghua 11 via radiation of ^60Co-γ in M2 generation. Every leaf of the mutant began to wither after it reached the biggest length, while the leaves of the wild variety could keep green for 25--35 d. In this study, genetic analysis and gene mapping were carried out for the mutant identified. The SSR marker analysis showed that the mutant was controlled by a single recessive gene （psl1） located on chromosome 2. Fine mapping of the psl1 locus was conducted with 34 new STS markers developed around psl1 anchored region based on the sequence diversity between Nipponbare and 93-11. The psl1 was further mapped between two STS markers, STS2-19 and STS2-26, with genetic distances of 0.43 and 0.11 cM, respectively, while cosegregated with STS2-25. A BAC contig was found to span the psl1 locus, the region being delimited to 48 kb. This result was very useful for cloning of the psl1 gene.

Method of moving target detection based on sub-image cancellation for single-antenna airborne synthetic aperture radar

The method of moving target detection based on subimage cancellation for single-antenna airborne SAR is presented.First the subimage is obtained through frequency processing is pointed out.The imaging difference of a stationary objects and moving object in the subimage based on the frequency division is analyzed from the fundamental principle.Then the developed method combines the shear averaging algorithm to focus on the moving target in the subimage,after the clutter suppression and the focusing position in each subimage is obtained.Next the observation model and the relative movement of the moving targets between the subimages estimate the moving targets.The theoretical analysis and simulation results demonstrate that the method is effective and can not only detect the moving targets,but also estimate their motion parameters precisely.     

锆合金腐蚀与防护研究进展

锆合金以其优异的核性能和生物相容性被广泛应用于民用发电反应堆、核动力航空母舰、核潜艇、空间飞行器的结构材料以及医用材料，在苛刻环境下服役的锆合金同样面临腐蚀失效的风险。由于材料本身服役环境的特殊性，使得锆合金腐蚀研究的模拟测试难度加大，诸多疑问难以得到有效解答。锆合金的腐蚀形式包括均匀腐蚀、疖状腐蚀、应力腐蚀以及微生物腐蚀，其腐蚀也受材料成分、热处理工艺、表面粗糙度、氧化膜成分、溶液的pH值、辐照、热流水化学环境以及温度等因素的影响，防护措施包括涂层和缓蚀剂等方式。为进一步改善锆合金的耐蚀性能，未来可从以下几方面展开研究：1)锆合金基体中固溶元素的浓度；2)第二相元素类型、晶粒尺寸及分布；3)氧化膜的生长机制；4)细菌附着方式和生物被膜生长行为等。     

An Exact Logarithmic-exponential Multiplier Penalty Function

In this paper, we give a solving approach based on a logarithmic-exponential multiplier penalty function for the constrained minimization problem. It is proved exact in the sense that the global optimizers of a nonlinear problem are precisely the global optimizers of the logarithmic-exponential multiplier penalty problem.

氮掺杂石墨烯的制备及其氧还原电催化性能

以三聚氰胺和氧化石墨烯(GO)为原料,经物理研磨和高温热解得到氮掺杂石墨烯(三聚氰胺-NG).扫描电子显微镜(SEM)测量显示,所制备的三聚氰胺-NG厚度和表面褶皱较掺杂前略有增加.X射线光电子能谱(XPS)表明,在三聚氰胺-NG中氮元素以吡咯N、吡啶N和石墨N 3种形式掺杂在石墨烯中,它们的比例分别是14.5%、24.5%和61.0%.同时运用循环伏安法(CV)和旋转圆盘电极技术(RDE)测试了三聚氰胺-NG在碱性介质中的氧还原电催化活性.结果表明,与商业石墨烯和由聚吡咯为氮源制备的氮掺杂石墨烯(ppy-NG)相比,三聚氰胺-NG具有较高的电催化活性和较正的氧还原起始电位(-0.09V),并且电催化还原氧气时主要为4电子反应.由于其较高的氧还原性能和较低的成本,三聚氰胺-NG在碱性燃料电池阴极电催化剂中有良好的应用前景.
