From the point of view of geobotany, with the method of correlative factors of growth of plants, a countrywide theoretic ecological division was done for the introduction of Camptotheca acuminata and three kinds of areas of ecological preferent zone, ecological adaptive zone and ecological unadaptable zone were divided. With the theory of synecology, the characteristic on environment, constitution, life form spectrum, diversity, similarity of plots of communities were researched. Applying the method of species association, discrete distribution, indensity index, fractal geometry, etc. to research relations between the species of the communities, space distribution of Camptotheca acuminata, structure of age of Camptotheca acuminata, in different communities. Using the theories of autoecology, distibutons of seeds on land and growth of seedlings in vertical and horizontal directions, biomass of organ of Camptotheca acuminata were analyzed. On the opinions of conservation biology, the external and internal factors impressing Camptotheca acuminata were analyzed to research the mechanism of the endangered species, and with using of CTM Model, the future development direction of Camptotheca acuminata in different communities were forecasted, and. Standing on the position of resources ecology, discussing the regularity of camptothein in Camptotheca acuminata of different sites and seeding of different resources, also the the derive technics of camptothecin.

MATLAB is a special-purpose computer program optimized to perform engineering and scientific analysis.It's easy to use and have a lot of powerful toolboxes which can be used in many aspects of engineering and scientific researches.

摘 要：凝胶电泳是当今分子生物学的一项最基本的试验技术，它的原理十分简单，但是通常只能通过目测marker的位置或是计算电泳率来得到样品的分子量，这样得到的结果是十分粗糙的。

This timely resource offers up-to-the-minute coverage of basic science and important clinical advances as well as future challenges and opportunities in the application of molecular and cellular biology to cardiovascular diseases.

这一及时的资源提供了对基础科学的和重要的临床应用进展以及未来的挑战并在分子和细胞生物学的应用心血管疾病的机会分钟的报道。

The Dchicago school established the basic position and principle of functional psychology in its debate with structural psychology,while the Colombia school puts its emphases on concrete things and has consequently made great achievements in specific studies and expanded research methods,laying a foundation for the future establishment of behavioral psychology.

正如黎黑所指出的，&意识的概念被重新更正，成了连续不断的运动反应、关系和机能，与行为主义没有什么区别&①。机能主义心理学的出现和发展不但开拓了心理学研究的视野，成为心灵主义心理学转向生物学的心理学的桥梁，并且为行为主义心理学的产生和发展奠定了基础。

From the phylogenetic tree constructed for IGF-I, the homology was as high as 95%, which revealed the relative relation between them was more closely than with others and give molecular biology support for the resolution of position and classification of lesser panda.

利用IGF-Ⅰ基因构建的进化树上，大熊猫和小熊猫此基因的同源性达到95%，并且显示小熊猫与大熊猫的亲缘关系与其它哺乳动物相比要近的多，为大熊猫及小熊猫的分类学提供了分子生物学的依据，但这样的结果也许与IGF-Ⅰ在物种间的高度保守性有关，我们认为，对于大小熊猫是否同属一科还需要进一步的研究。

Peptide nucleic acid is a kind of new nucleic acid mimic invented in the early 1990s', in which the deoxyribose phosphate backbone has been replaced by a pseudo-peptide polymer to which the nucleobases are linked. PNA is uncharged, highly stable in chemical and biological environments, and binds complementary DNA and RNA targets with remarkably high affirnity and specificity.

肽核酸是二十世纪九十年代初合成的一种全新的核酸类似物，它以多肽骨架完全替代DNA中的脱氧核糖磷酸二酯键的骨架，呈电中性，具有极高的生物和化学稳定性、极强的核酸结合能力和特异性，在分子生物学的许多方面得到广泛应用。
