index similarity
1.In order to find out the fish diversity of Lancang Jiang and Lixian Jiang in Simao district,the Cody index,Routedge index and similarity coefficient in the binary feature data of β diversity,with Lvzhi Jiang and Nanxi He(2 arterial branches of Red River) were calulated as accessorial samples.
2.We also describe the affiliation index of balkanization, similarity of information resources and offer the conditions under which virtual balkanization emerges.
4.All of that indicate that the tropical and temperate elements coexist in Luoping. By the methods of Abundance Index, comparing dominant families and genera, Similarity Coefficient of Genus, Principal Components Analysis, the bryoflora is compared between 3 karst valleys as well as between Luoping and other 11 areas in China.
5.Bray-Curtis community similarity index is used to deal with the community similarity and cluster analysis. The result shows that Chitons community in rocky intertidal zone of the islands in south Zhejiang can be clustered into two types.
6.Fractional Brownian motion(FBM) is used in the parameterized modeling of base distributing of DNA sequence. Using mexihat wavelet do wavelet transform and Hurst index is calculated which can describes the self-similarity of DNA sequence.
7.European eel is 0.717 andAmerican eel is 0.686. The similarity index between Japanese eel andEuropean eel is 0.557;
8.We studied the application of the LSI(latent semantic index) for FAQ construction in Chinese automatic question and answer system,and emphatically introduces computing technology in sentence similarity and experiment methods of using latent semantic index for FAQ repetition. The result showed the LSI was better than the TF×IDF.
9.The result showed that the genetic characters of nonsymmetrical crossing filial generations were similar to that of the mononuclear accepter-parent with a genetic similarity index of about 85%, and that more genetic diversity exsisted between the nonsymmetrical crossing filial generation and the binuclear donor parent with a genetic similarity index of about 61%.
10.But more genetic diversity existed between English and American strains of Trichoderma and the genetic similarity index was below 50 % .
