The specific PCR products of approximately 112bp in length was amplified from the other 10 strains of E.faecalis from lamb naturally infected with E.faecalis,lamb and mouse experimentally infected with E.faecalis by the PCR assay,but no any bands were amplified from Streptococcus equi subsp.equi,Streptococcus G,Streptococcus A,Staphylococcus aureus,Listeria monocytogenes from sheep,Mycoplasma ovipneumoniae and Brucella ovis.

应用该方法对分离的致羔羊脑炎粪肠球菌、由肠球菌导致发病或死亡羔羊脏器以及人工感染死亡小鼠的主要脏器进行扩增，均能得到特异性的DNA条带；对其他7种病原菌，马腺疫链球菌C群、G群链球菌、A群链球菌、金黄色葡萄球菌、羊源李氏杆菌、绵羊布氏杆菌、绵羊肺炎支原体不能扩增出特异的DNA条带。

Under natural conditions and with human activity, the dominance of Oxytropis coerulea become weaker than ever among associations, which reflects a tendency of inverse succession, while those which are less disturbed by human activity show xerosere character because of poor habitat.

在自然条件和人为干扰双重作用下，蓝花棘豆Oxytropis coerulea在群丛中的优势度明显弱化，群丛反映出逆演替趋势，受人为干扰较少的群丛则由于生境条件较差显现旱生演替特征。

The cytoarchitectonic organization ofprojections to the insular cortex and the amygdala from the parvicellular ventroposterior nucleus of the thalamus andtheparabrachial nucleus in the rat was investigated by means of horseradish peroxidase -tracing technigue; The relationship of origins of afferents to the insular cortex and the amygdala from the PBN was studied by using the retrograde transport of two fluorescent tracers; Thesynaptic connections of axonal terminals with the neuronsof the PBN were observed by means of electron microscopy.

GI主要位于岛皮质的尾侧部，DI和AI主要位于首侧部；VPpc是位于丘脑腹后核和内侧丘系之间的带状区，所含细胞较小(平均14u)，其内侧部称为腹后内侧核小细胞部，其外侧部称为腹后外侧核小细胞部；PBN位于小脑上脚周围，由三部分组成：外侧亚核、内侧亚核和Kollikor-Fuse核，其中，PBl被分为7个区、PBm被分为3-4个区；杏仁核主要由三个细胞群组成：皮质内侧核群、基底外侧核群和中央核，中央核又有内侧部、外侧部和外囊部之分。

The algorithm for optimizing parameter is applied and effective,and is much better than that of common Genetic Algorithm,and has good perfectible application future.

文献[2]提出用模糊控制算法整定PID参数，文献[3]将Bang-Bang控制与神经网络自适应控制相结合，利用神经元的学习功能构成了一种自适应PID控制器，文献[4]以蚁群系统和蚁群算法为基础，提出了一种新的具有不完全微分的最优PID控制器的设计方法，文献[5]提出一种利用改进微粒群算法优化PID参数的方法。

A number of microplants with spherical, triangular, polyangular and boat-like shapes have been found both from the early Palaeoproterozoic Dashiling and Qingshicun Formations (ca. 2500- 2400 Ma) of the Doucun Subgroup of the Hutuo Group and the late Palaeoproterozoic Changzhougou and Chuanlinggou Formations (ca. 1800 -1700 Ma) of the Changcheng Group in North China. According to the features of these fossils, such as size, external shape and internal structure, they may belong to unicellular eucaryotic planktons.

在华北地区古元古代滹沱群豆村亚群的大石岭组、青石村组(约2500～2400 Ma)和长城群的常州沟组、串岭沟组(1800～1700 Ma)中存在着大直径的球形和形态呈三角形、多角形及船形微古植物，根据它们的大小、外部形态和内部结构等综合判别，它们可能属于单细胞真核浮游生物。

Ehlers-Danlos syndrome is a genetically heterogeneous connective tissue disorder which is comprised of more than 10 phenotypes including EDS-Ⅷ, which is characterized by chronically inflamed pretibial lesions and severe periodontitis.

Ehlers-Danlos徵候群是一群由多种基因异常所致的结缔组织疾病，有超过十种以上的表现型，其中Ehlers-Danlos徵候群第八型有其特别的临床特徵：胫前皮肤有慢性发炎性的斑块再加上严重的早发性牙周炎。

Although previous studies have revealed that functional dyspepsia is associated with psychopathological factors and personality, the association is heterogeneous among FD patients, reflecting their diverse underlying pathophysiological mechanisms.

有鉴於高度的异质性，目前的诊疗准则(罗马III准则，Rome III criteria)提议以更专一的疾病诊断来取代功能性消化不良：罗马III准则将功能性消化不良作进一步次分类，因而定义两个症候群：功能性上腹痛症候群和餐后不适症候群。

In order to fully know the alteration of microbial community in chick, the influence of different kinds of pathogenic microorganism on chick, and the difference of intestinal flora, in this paper analysed the structure of intestinal flora of pullorum disease group, newcastle disease group and healthy group by ERIC-PCR based fingerprint on Molecular Ecology.

中文摘要：为了全面掌握鸡肠道微生物群落结构变化，人工感染病原微生物对雏鸡肠道菌群结构的影响以及不同类型病原微生物对菌群的影响是否存在差异，本文应用ERIC-PCR指纹图谱技术，对鸡白痢、新城疫感染雏鸡以及健康鸡的肠道菌群结构特征进行了分子生态学研究。

This paper made detailed studies through karyotype analysis and allozyme analysis on the materials which including 9 species of the genus Lycoris and different populations of Lycoris radiata Herb..

本研究以石蒜属9种植物以及石蒜的16个居群植物为研究材料，通过核型和同工酶研究和分析手段，对石蒜属植物种间和石蒜居群间进行了详细研究；进一步揭示了石蒜属种间以及石蒜不同居群之间的差异；为探讨石蒜属植物的系统关系和资源进一步开发利用提供基础资料。
