中文摘要：

研究两个序列集合之间相似性度量，提出基于拉普拉斯矩阵特征值的分离度概念和公式表示．基于人工序列和真实DNA序列上的实验结果，证实了分离度能够度量序列间的相似程度．

英文摘要：

Similarity measure between two sequence sets are studied, and the concept, as well as the expression of a new divergence is proposed. Experiments on synthetic data and real DNA sequence sets show that this divergence can measure the similarity between sequence sets.
