In this paper the Lannigou and Getang gold deposits were considered as typical Carlin-type gold deposits in Southwest Guizhou, China, with the aim to state the relationship between organic matter and mineralization based on the organic petrological study of solid organic matter in the two deposits.

本文以黔西南烂泥沟和戈塘两个典型金矿床为例，系统研究了其中的固体有机物质的有机岩石学特征，并探讨了固体有机质与金矿化的关系。

The sort of new drug of TCM,the declare of new drug of TCM and the manufacture of new drug of TCM(including technics research, establishment of quality standard, pharmic research, toxicology research and clinic research) are introduced systematically.

该课程系统介绍中药新药分类、申报和研制的基本知识、技能，主要内容包括中药新制剂工艺研究、质量标准的制定及稳定性试验、药效学研究、毒理学研究、临床研究。

The history and current situation of research in speech recognition are proposed all-sidedly and systematically. We probe into such topics about acoustic features, phonetic features, phonologic features and auditory perception in terms of related theory and disciplines. Furthermore, we summarize and analyze focus in current theoretical and technical aspects of speech recognition and immediately put an insight into challenge to speech recognition presently, even in a long time.

论文全面、系统地介绍了国内外语音识别的发展历史和发展现状，结合相关学科的知识，分析了语音声学特征、语音学特征、音系学特征及其语音感知等有关问题，分析并总结了目前语音识别理论和技术实现方面的研究重点以及目前、甚至在相当长的时期内语音识别面临的挑战。

Through the traditional physiological and biochemical method, together with the 16SrDNA sequence homology and phylogenetic analysis, the strains were identified. The result shows they belong to the genus photobacterium, but they differ from any species of this genus in some characteristic which suggests they might be new species, and their taxonomic placement needs more information on genes level.

对两株菌进行鉴定，分析其生理生化特征和16SrDNA产物序列，确定这两株菌均属于发光杆菌属，但是和该属的各种还有一定差异，对其分类地位的最后确定还需进一步的系统发育学分析。

The soil depth of 30～40 cm could be taken as a shift depth of the vertical distribution of Phragmites communis belowground biomass.

基于2005年4～9月盘锦湿地芦苇生态系统的观测资料，分析了盘锦湿地优势植物芦苇的群落学特性。

The successive start-up of genome project in recent years has far-reaching impact on present phylogenetic studies.

生物基因组计划的相继启动对系统发育学研究的发展产生了深远影响。

Phylogenetic analysis showed that the proteobacteria were the dominant group both in the sediments and waters,γ-proteobacteria and δ-proteobacteria were dominant in the sediments,α-proteobacteria were dominant in the water. However, all subphyla of proteobacteria presented phylogenetical divergence at the two sites.

各站位中主要为变形菌门，沉积物中γ-Proteobacteria和δ-Proteobacteria亚门占优势，水中则以α-Proteobacteria亚门占优势，但各亚门微生物在两个站位中存在明显系统发育学分歧。

Genome and EST sequencing projects generate a wealth of sequence information for agronomically and phylogenetically important plant species of which the majority is difficult to subject to functional genomics.

农艺上和系统发生上重要的植物物种的基因组和EST测序计划产生了大量的序列信息，其中大部分难以服从功能基因组学。

In addition, a pre-column derivatization HPLC method was applied to the determination of Astragaloside Ⅳ; the flavonoids was determined by full-range HPLC scanning; a colorimetric method was developed for the determination of flavonoids and saponins. Hierarchical cluster analysis was performed on three constituents of different Radix Astragali species, and its result was compared with those of traditional phytoecological identification and the pharmacological quality assessment.

本研究以比色法测定了黄芪中总皂苷的含量，以柱前衍生化高效液相色谱法测定了黄芪中黄芪甲苷的含量；以比色法测定了黄芪中总黄酮成分的含量，以反相高效液相色谱法测定了黄芪中毛蕊异黄酮和毛蕊异黄酮苷的含量；以黄芪中的黄芪甲苷、毛蕊异黄酮和毛蕊异黄酮苷为主要特征对不同品种的黄芪进行了系统聚类分析，并将聚类结果与传统生药学鉴定和药理质量评价结果进行了比较。

According to the phytosociological theories and methods of Braun-Blanquet's school, the regional savanna vegetation of the dry-hot valleys of Yuanjiang river had been investigated. Based on the principle of fidelity degree, the typical 110 releves taken from every sampling stands of the dry-hot valleys were sorted up from below to upper into 15 Associations, then into 5 Alliances, 2 Orders and 1 Class. A synoptic classification system of Class-Order-Alliance-Association was established for the purpose to reflect deeply the characteristics of all syntaxa there in the aspect of plant component and their abundance-dominancy, presence, cover coefficient, life form, growth form, and ecological environment, community structure, species types and so on.

采用Braun-Blanquet植物群落学研究的理论与方法，对云南元江中上游干热河谷分布的植被进行考察研究，把各处取得较典型的110个样地记录按确限度的原则由下而上归类成15个群丛、5个群属、2个群目和1个群纲，建立了元江干热河谷萨王纳植被群纲—群目—群属—群丛分类系统综合表和15个群丛表，以全面深入反映全干热河谷植物群落各级分类单位中各植物种类组成的多优度、存在度、盖度系数、生活型和生长型等特征及其群落结构、生态环境和种型类别。
