机载脉冲多普勒雷达回波信号模拟

回波信号作为雷达信号处理之源,它的模拟对研究雷达系统仿真具有非常重要的实际意义。在研究雷达回波特性的基础上,获得雷达回波信号的准确表达式,采用映象法将地面分成大杂波单元和小杂波单元,对各小杂波单元产生的回波采用矢量相加以求得相干视频信号,计算整个距离环的回波获得完整的雷达回波信号。最后的仿真结果证明了计算的正确性。

Strategy for the mapping of interactive genes using bulked segregant analysis method and Mapmaker/Exp software

A qualitative trait is usually controlled by a single gene, but it may be sometimes controlled by two or even more genes. This phenomenon is called gene interaction. Rapidly searching for linked mo- lecular markers via bulked segregant analysis (BSA) and then constructing regional linkage map with Mapmaker/Exp has become a common approach to mapping single major genes. However, methods and computer programs developed for mapping single major genes cannot be simply applied to interactive genes because the genetic patterns of gene interac- tions are quite different from that of single-gene in- heritance. Up to now, experimental methods for quickly screening molecular markers linked to inter- active genes and statistical methods and corre- sponding computer softwares for simultaneously analyzing the linkage relationships of multiple mo- lecular markers to an interactive gene have not been available. To solve this problem, in this paper, we propose a strategy for mapping interactive genes using BSA and Mapmaker/Exp. We demonstrate that all interactive genes can be mapped by the 'BSA Mapmaker/Exp' strategy using F2 generation (in a few cases, F3 generation is also needed). As BSA and Mapmaker/Exp have been broadly used in gene mapping studies and are well known by many re- searchers, the strategies proposed in this paper will be useful for practical researches.     

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.

《走出非洲》中狮子的象征意义

分析了《走出非洲》一书中狮子的象征意义,认为它既是非洲草原的代表性动物,又是作者丹麦女作家凯伦.布里克森表达各种思想情感的媒介。狮子代表神秘、威猛和勇敢,但也以高贵和权威为特征。作者正是以狮子作为象征,充分地表述了她个人的爱情观、生活观和对高贵品质的理解。

李商隐爱情诗的朦胧美

李商隐的爱情诗意境深邃，词语隽永，忽断忽续，或彼或此，具有一种朦胧美。李商隐由于政治上的失意潦倒，生活中爱不得其所爱和得而复失，再加上他善于学习前人雕章琢句的典丽文风，这就形成了他爱情诗的特有的朦胧风格。本文对李商隐爱情诗歌的朦胧美从意象、词语、章法上进行了阐释和分析。
