基于改进相关邻域模型的SAR图像RCS重构

提出了一种基于改进相关邻域模型的SAR图像RCS重构滤波器,特别对高分辨率的SAR图像具有很好的去斑效果。本算法虽然是一种RCS重构算法,但是通过采用非线性积累的方法,可明确地把图像划分为阴影、背景和目标区,直接达到SAR图像目标检测的结果。本算法在平滑图像的同时,克服了多视平滑降低图像分辨率的固有缺陷,并且能较好地保持图像的边缘信息,能极大地提高后续SAR图像解释的效率。     

徐州、铜山地区矿产赋存的地质条件和进一步找矿的方向

徐州、铜山地区矿产资源丰富,至今仅开发部分煤、内生铁矿和石灰岩。根据地层、地质构造和岩浆岩特征分析,这地区不仅存在许多上述矿产,而且拥有大量铝土矿、沉积铁矿、白云岩、迭层石石灰岩、铜、金和银等矿床。应向新区和按确定的标志寻找新矿,或采用综合方法开采靠近煤层的矿床。

Genomic and genic sequence variation in synthetic hexaploid wheat （AABBDD） as compared to their parental species

In order to understand the genomic changes during the evolution of hexaploid wheat, two sets of synthetic hexaploid wheat from hybridization between maternal tetraploid wheat （AABB） and paternal diploid goat grass （DD） were used for DNA-AFLP and single strand conformation polymorphism （SSCP） analysis to determine the genomic and genic variation in the synthetic hexaploid wheat. Results indicated that more DNA sequences from paternal diploid species were eliminated in the synthetic hexaploid wheat than from maternal tetraploid wheat, suggesting that genome from parental species of lower ploidity tends to be eliminated preferentially. However, sequence variation detected by SSCP procedure was much lower than those detected by DNA-AFLP, which indicated that much less variation in the genic regions occurred in the synthetic hexaploid wheat, and sequence variations detected by DNA-AFLP could be derived mostly from non-coding regions and repetitive sequences. Our results also indicated that sequence variation in 4 genes can be detected in hybrid F1, which suggested that this type of sequence variation could be resulted from distant hybridization. It was interesting to note that 3 out of the 4 genes were mapped and clustered on the long arm of chromosome 2D, which indicated that variation in genic sequences in synthetic hexaploid wheat might not be a randomized process.
