Taxonomy can lay claim to being the oldest, the most basic and the most all-embracing of the biological sciences

分类学可以说是最古老，最基础而又最包罗万象的一门生物学科。

Works on marine micropaleontology in China started in the late 1950's, and in the last thirty years, the marine micropaleontology in China has been greatly expanded into a full-fledged discipline that includes taxonomy, ecology, sedimentology, biostratigraphy, paleoenvironmental analysis and geologic resources prospecting, and deals with finding and explaining various species buildup, ecologic condition, sedimentary distribution, and their historical processes.

中国的海洋微体古生物学研究开始于20世纪50年代末，当时属于起始摸索阶段。真正发展并奠定基础的时期是在近30年以来，较为全面地开展了分类学、生态学、沉积学，生物地层学、古海洋环境分析与地质资源勘探应用研究等。

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。

In the present paper the essentials of the concept and method of quantitative parsimony analysis for cladogram construction are revealed.

数值简约性原则是分支分类学进行分支分析及重构生物演化分支图的主要思想方法。

It makes sense of the geologic record, biogeography, parallels in embryonic development, biological homologies, vestigiality, cladistics and other fields, with unrivalled explanatory power; it has also become essential to applied sciences such as medicine and agriculture.

它以无与伦比的解释力，合理地解释了地质记录、生物地理学、胚胎发育的类似、生物同源性、退化遗迹、遗传分类学和其他的领域；它也已经成为应用科学的基本要素。
