树状图 meaning in English
dendrogram
tree diagram
tree view
Examples
- Decoding algorithm of unequal error protection block code based on tree topology
基于树状图的不等保护分组码译码算法 - Md5 catalog tools - tools for maintaining file catalogs in directory trees . these can be used to to check for duplicates and verify correct transfer to other media
用来维护子目录树状图的文件目录工具。这些树状图可以用来检验复制和检查是否把目录正确传输到其他媒体。 - Obviously , it is far from the requirement to determine the taxonomy condition depending on morphological characters alone , for there are too many reasons that will lead to wrong classification
从树状图很容易看出仅仅通过形态学指标对粘细菌进行分类已经不能满足需要，许多外界因素都会导致错误分类。 - 2 . 5 ul of 10 x reaction buffer , 1 . 5 ul 25mm mgcl2 , 0 . 3 ul lomm dntp , 0 . 5 ul taqdna polymerase ( 5 u / ul ) , and lul ( = 20ng ) of primer were used in per reaction . each reaction was overlaid with one drop of paraffin oil . the initial denaturation step was used at 94 for 1 min 45 sec ; then denatured at 94 for 30 sec , annealed at 37 1 min , extended at iv b 72 for 2 min and repeated the cycle 45 times , at last , extended at 72 ' c for lomin
等( 1995 )利用rapd标记区分美国东部一杂交地带的蟋蟀的两个姐妹种， allonemobiusfasciatus和a . socius ，并于1998年使用rapd和异型酶标ic做出了这两种蟋蟀的基因连锁图；国内田英芳、郑哲民（ 20of ）首次将rapd技术运用于蟋蟀总科的分子系统学研究中，采用2种引物对7种蟋蟀进行了基困组dna多态性研究，并应用upg问a法构建树状图，椎测系统发生关系 - Primers of ecori were signed with fluorescent dye and four pairs of primers were selected from twenty - four pairs . 261 dna fragments were generated by the four pairs of primers in forty - three individuals sampled . percentage of polymorphic bands is 51 % , the value of shannon index ( i ) is 0 . 086 and nei ' s gene diversity ( h ) is 0 . 151
统计这些aflp表型带标记，用popgene软件计算各种多样性数据( ppb值为51 ， shannon多样性指数为0 . 086 ， nei ' s基因多样性值为0 . 151 ) ：用ntsys软件计算各个样品间的相似性系数，并用upgma法基于相似性系数进行聚类分析，构建树状图，它们可反映出元宝山冷杉种群内个体间的遗传关系。
