简介:目的了解福建汉族人群D2S44、D10S28、D4S163VNTR多态性,为亲权关系概率计算提供基因频率。方法采用美国Lifecodes公司提供的VNTR检测试剂盒,应用RFLP技术首次对福建省9个地市103名汉族无关个体进行D2S44、D10S28、D4S163VNTR多态性研究,并将所得基因频率与中国台湾、香港、新加坡等地区进行比较。结果福建汉族人群三位点VNTR呈高度多态性,其杂合率分别为88.6%、86.3%、90.6%,呈孟德尔经典遗传,分布符合Hardy-Weinberg平衡定律。结论福建、台湾、香港、新加坡华人互为比较,D2S44、D10S28位点基因频率没有显著性差别(P>0.500)。
简介:摘要:为了提升目标类型识别的准确率,提出了一种综合的目标类识别方法。在单传感器层面上采用基于灰色关联理论进行初步识别,最后采用D-S证据理论对多传感器目标类型进行综合识别。仿真结果表明,本文方法能够提高目标类型识别的准确性。

简介:a novel should be a history. From the introduction of Thomas Hardy and the main content of Tess of TheD’urbervilles must be helpful to show us the background of Clare’stragedy.,哈代的悲剧小说《德伯家的苔丝》真实地反映了其当时的社会现实,the last tragedy was the most terrible one which we can see in Hardy’sworks. Hardy began to creating the novels in the early 1870s. In the late 1890s
