中文摘要：

利用上下文相关隐Markov模型建立neRNA基因基本二级结构模型，从两序列比对结果中提取序列相似性信息，并把该信息引入基本的上下文相关Markov模型中，从而构建出新的neRNA基因识别模型。

英文摘要：

This paper uses context- sensitive hidden markov for basic ncRNA secondary structure,and distills similarity information from result pair- wise alignment of two sequences that is close in evolutionary distance. Then we introduce the idormafion into the basic secondary structure model and get the novel ncRNA gene finding model consequently.
