Progress in the taxonomy of the actinomycetes and acidophilic actinomycetes was introduced in this paper. The diversity of acidophilic rare Actinomycetes from acidic soil was studied and a polyphasic study was undertaken to establish the taxonomic position of three soil isolates.

本文介绍了放线菌和嗜酸放线菌的分类学研究进展，研究了我国酸性土壤中稀有放线菌的生物多样性，并采用以分子分类、系统发育学分析、化学分类、形态特征和生理生化特性相结合的多相分类方法对3株土壤新分离菌株进行了分类学研究。

In view of the many different interpretations of the systematics of these snakes, a "taxonomic conversion table" is provided here, with the aim of allowing the classifications used in different publications to be related to each other.

鉴于亚洲蝮在分类学上的许多不同译法，在这里提供了一份以适用于互相关联的不同出版物之间的"分类学转换表格"。

Other courses like dendrology for gardening, taxonomy of seed plants, plant classification or plant systematics may be similar or overlap in some degrees. However, dendrology focuses on woody plants, especially on trees from gymnosperms and dicotylerdons of angiosperms. Dendrology for gardening is more suitable for students from specialties relating to gardening.

类似并可以在一定程度上起替代的课程为园林树木学、种子植物分类学、植物分类学或植物系统学，但树木学主要侧重于木本植物的分类，而且主要集中在裸子植物和被子植物的双子叶植物纲上中；园林树木学则主要适用于园林相关专业的学生。

According to these evolutionary trends especially structure of stigmas and results of studies of the genus in Taxonomy, Cytotaxonomy, Palynology and Anatomy, a new system of classfication of the Asp...

依据这些演化趋势尤其是柱头构造的差异，并参考了形态分类学、细胞分类学、孢粉学和解剖学研究的结果，提出了蜘蛛抱蛋属的新分类系统

This difference in structural as opposed to behavioral systematics may be entirely due to the limitations of human observation and insight.

结构的分类学相对於行为的分类学之间的差异可能完全是因为人类观察以及眼光有局限。

The methods of classical classification, integrating the study on seed morphology and leave epidemics morphology, along with phytomorphology, phytotomy, phytoembryology, palynology, phytocytotaxonomy, phytochemistry and molecular systcmatics, were used to revise and complete the former taxonomic system.

以经典植物分类学方法为基础，结合种子形态学和叶表皮形态学的实验研究，参考植物形态学、植物解剖学、植物胚胎学、孢粉学、植物细胞分类学、植物化学和分子系统学等方面的资料，对前人的五味子属分类系统进行修订和补充。

因此，刺胞动物分类学研究越来越受到关注，已成为无脊椎动物分类学新的研究热点之一。

Objective To observe the terminalia of adult female mosquito and explore taxonomic method for mosquito identification.

目的 对我国广东省野外采集的15种蚊虫雌蚊尾器进行形态和分类学观察并探讨其分类学意义。

Results The female terminalia of fifteen species mosquitoes can be identified according to different morphological characters.

利用雌蚊尾器区分蚊虫种类是一种有效的分类学手段，在蚊虫调查研究中有分类学实用价值。

On the basis of the works of our predecessors. I. try to make a thorough and systematic study on the Chinese Iris by means of pollen morphology、cytotaxonomy、esterases Isozyme and numerical taxonomy and combining the morpholoyical characteristics and plant geography. The experimental results are summarized as follow

基于上述原因，本文在前人工作的基础上，试图利用花粉学、细胞分类学、同工酶学及数量分类学等手段，并结合形态学特征及地理分布特点，对中国鸢尾属进行了较为系统的研究，获得以下几方面的结果

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
