The similarity analysis with non-metric MDS method reveals that exclosure results in lower similarity among vegetation quadrats, this difference, however, doesn't reflect from soil seedbank, the lag effect between soil seedbank and vegetation should be focused on in further study.

地上植被和土壤种子库间的相似性分析结果则表明相同措施同一土层间种子库中等相似，而不同土层间还是存在着一些差异。由于封育措施导致了植被样方的相似性较低，然而土壤种子库间的相似性仍然较高，两者间是否存在着一定程度的滞后效应有待于进一步研究。

The comparison of the predominant bacterial community structure in the gastrointestinal walls between Lutjanus sebae (Cuvier, 1816) and Ephippus orbis (Bloch, 1787) based on 16S rDNA PCR-DGGE fingerprint using a culture-independent method was conducted in the paper. The results showed that abundant bacterium were planted in the gastrointestinal walls of both marine finfish species, the similarity was above 50% in the community structures in the gastrointestinal walls with the highest similarity of 67% in the bacterial composition between the intestinal wall of Luljonus sebae and that of Ephippus orbis, and the walls of the stomach and the intestinal in one fish shared the same most predominant bacteria species, which might reflect the same aquaculture environment and the diet fed for both finfish species.

本文采用免培养的16S rDNA梯度凝胶电泳技术对集约化海水网箱养殖川纹笛鲷Lutjanus sebae、及圆白鲳Ephippus orbis消化道壁优势菌群结构进行了比较分析研究结果显示川纹笛鲷及圆白鲳消化道壁存在着大量细菌群落，对DGGE指纹图谱聚类分析表明两种鱼肠道壁及胃壁菌群组成相似度高于50%，其中二者肠道壁细菌组成相似性最高(67%)，这些可能与两种鱼养殖在同一水域、摄食相同饵料相关，另外通过软件对DGGE指纹带谱相对丰度分析表明同种鱼肠道壁及胃壁具有相同最大优势菌群。

The similarity measure of the clustering objects heavily affects the cluttering result, so the author studies the problems about similarity measure, and proposes a generalized distance.

聚类对象的相似性度量对聚类结果的影响很大，因而研究了聚类中的相似性度量问题，提出了广义距离概念。

The different fishes which are employed in the present studies are wild-type salmon, cultured salmon of freshwater and seawater, sea perch and fat greenling. The complete CT gene sequences of salmons are obtained by PCR amplification. The partial CT sequences of sea perch and fat greenling are obtained by in vitro cloning PCR method. Alignment of obtained CT sequences with other fish CT shows that CT appears to be well conserved among the same family. And the relative in taxonomy is far away, the similarity of different fish CTs is low. On the contrary, the closer the relative in taxonomy is, the higher the similarity of different fish CTs is. The sCT is expressed in pGEX-4T-X by recombinant form . We also succeed in the research of sCT expression alone by expression PCR. In addition, sCT antiserum is obtained using GST-sCT as antigen, and the high titer is tested by double immunodiffusion. In the rat bioassay, administration of 50 μg recombinant protein evoked significant hypocalcemia at 1 h after the data are analyzed by t-test.

本文用PCR方法克隆了野生鲑鱼、养殖鲑鱼的降钙素基因，并应用体外克隆PCR的方法首次克隆出鲈鱼、六线鱼降钙素的部分基因序列，通过对克隆的降钙素序列的比较研究，结果显示同一科的鱼降钙素序列保守性较高，同时，根据降钙素的部分氨基酸序列进行了降钙素相似性的比较研究，结果显示在分类学上，分类地位较远的鱼，其降钙素相似性较低，分类地位越接近的鱼，其降钙素相似性越高；我们利用谷胱甘肽S-转移酶(Glutathions S-transferase，GST)融合表达载体pGEX-4T-X对克隆的鲑鱼降钙素基因进行了融合表达研究，应用表达PCR的方法对降钙素基因的独立表达进行了初步的研究探索，并将纯化的融合蛋白作为抗原，获得了高效价的兔抗鲑鱼降钙素免疫血清；生物活性研究表明，大肠杆菌表达的融合蛋白具有显著的降血钙作用。

From the RAPD analysis data, the band similarity rates and average band similarity rates between two individuals in the sampling population, average band allele frequencies, average band heterozygosis degree, and the Shannon genetic diversity index were calculated to perform the cluster analysis of heterozygosis arithmetic averages and construct the phylogenetic tree.

根据RAPD结果分别计算了两两个体间的带纹相似率、平均带纹相似率、带纹的平均等位基因频率和平均带纹杂合度及遗传多样性指数，作亲缘关系的类平均聚类并绘制了相关关系聚类图。

We find that the "spurious" ORFs (IHI 14) distributed mainly in three classes, namely, in the class of "similarity to unknown proteins","no similarity" and "questionable ORFs".

我们发现，虚假的ORFs(IHI≤14)主要分布在三类ORF中，即：和未知蛋白相似的ORF，无相似的ORF，以及可疑的ORF。

We find that the"spurious"ORFs (IHI≤14) distributed mainly in three classes, namely, in the class of"similarity to unknown proteins","no similarity"and"questionable ORFs".

利用非均匀指标，我们以14为界，当IHI＞14，认为该段序列为编码区，当IHI≤14，认为是非编码区，可以将编码区和非编码区以95％的精度区分开来。
