例句与用法

1. Detection of dna tag sequences for rapid identification of yersinia pestis
   标识序列的鉴定及其应用研究
2. Among sequenced 16 positive clones randomly selected , two represent novel expression tag sequences , two are homologous to two unknown proteins in genbank ; the rest are homologous to known or putative proteins or enzymes with definite functions by searching the genbank through blast program , which are involved in various life activities of cell such as regulation of gene expression , plant secondary metabolism , signal transduction , adversity resistance , stress response and defense reaction . significant changes of quantities of these gene fragments were observed before and after ssh , which indicated they were enriched after ssh
   随机挑选了16个差异表达的克隆进行序列测定，经与genbank数据库相关数据比较分析，发现有2个新的cdna片段( ets ) ，有12序列与genbank中已知蛋白或推测蛋白质( putativeprotein )序列有高低不同的同源性，它们参与基因的表达调控、植物的次生代谢、信号传导、抗逆、应激及防御反应等细胞生命活动过程。
3. At first , the text is segmented to words and converted to a sequence of part - of - speech tags ; then based on the pos tags sequence parameters and phrase - break distance information from training , markov model is used to get the most likely phrase break sequence
   首先，文本进行分词，并转换为一列由词性标记所组成的序列；然后使用马尔可夫模型，利用人工标注数据库训练词语连接处词性标注序列的概率分布和连接类型序列的距离信息，得到输入的词性标记序列对应的具有最大似然概率的连接类型序列，最后利用后处理规则进行适当的纠错。
