All results from morphological, physiological and biochemical characterization, the 16S rDNA sequence and phylogenetic assay identified that the strain belongs to Micrococcus luteus. The DNA fragment encoding mature peptide of fibrinolytic enzyme was cloned by PCR and sequenced.

利用传统细菌分类鉴定方法对其形态和生理生化特征进行了研究，发现其与藤黄微球菌的特征相符， 16S rDNA序列分析的结果也表明它与藤黄微球菌的16S rDNA序列的同源性高达99%，因此该菌在系统分类学上属于微球菌属藤黄微球菌。

Above all,there are some obvious differences among species in distributive density of oil cells, in distribution places of oil cells and mucilage cells and in their sizes. Those structural characteristics are significant for the classification of Lauraceae.

因此，叶片内油细胞的分布密度、油细胞和粘液细胞的分布位置及其大小在种与种之间存在明显的差异，此种结构特征具有分类学上的意义。

It is powerful for multicollinearity,particularly when the number of predictor variables is large and the sample size is small,and provides a novel and efficient algorithm for pattern recognition.

1概述模式识别是智能信息处理中的一个重要学科领域，不是一门简单的分类学，而是包括对系统的描述、理解与综合，它要通过大量信息对复杂过程进行学习、判断和规律的寻找。它所研究的理论和方法在很多科学和技术领域中得到了广泛的重视，推动了人工智能系统的迅速发展[1-2]。在大

In order to diagnose disease caused by muscovy duck parvovirus rapidly and accurately, and at same time, further study the taxonomic relationship between muscovy duck parivovirus and goose parvovirus, two pairs of PCR primers (LHMP1/LHMP2 and LHGP1/LHGP2) were designed respectively base on complete nucleotide sequences of Muscovy duck and Goose parvoviruses registered in the GenBank, The LHMP1 for the upper one and the LHMP2 for the lower one, corresponding to the specific nucleotides sequence 454-472 and 1173-1155 respectively in MDPV, and the LHGP1 for the the upper one and the LHGP2 for the lower one, corresponding to the specific nucleotides sequence 454-472 and 1173-1155 respectively in GPV.

为了能快速、准确地对番鸭细小病毒病进行诊断，同时为了能进一步弄清番鸭细小病毒与鹅细小病毒在分类学上是一种怎样的关系，比较GenBank中MDPV和GPV的基因序列，针对这两种病毒左阅读框编码非结构蛋白基因序列的相同区段，分别构建两对PCR引物。第一对引物LHMP1／LHMP2是根据MDPV的基因序列设计的，上游引物针对MDPV基因序列的454～472；下游引物针对基因序列的1173～1155，为19个碱基，扩增跨幅为719bp。

Its plant anatomy, mycology, plant pathology, physiology, systematics and conservation also feature prominently.

该系的植物解剖学，真菌学，植物病理学，生理学，分类学，和保护学特色也非常显著。

The journal covers abstracts of the world's literature on insects and other arthropods which transmit diseases or are otherwise injurious to man and to animals of significance to man, with subject on arthopods which are disease vendors, haematophagous, ectoparasitic, agents of myiasis, allergenic, associated with carrion or dung, venomous or toxic, or otherwise of public health importance, including physiology, taxonomy, ecology, genetics, molecular biology, immunology, disease transmission pest management, pesticides, entomopathogens, parasites and predators.

杂志刊载世界各地传播疾病或对于人类重要的其他对人类和动物有害的疾病的昆虫和节肢动物方面文献的摘要，主题涉及传播疾病的，吸血的，外寄生的，蝇蛆病的媒介，引起过敏的，以及腐肉，粪便，有毒的节肢动物，或其他的与公共卫生有重要关系的方面内容，包括生理学，分类学，生态学，遗传学，分子生物学，免疫学，疾病传播昆虫的管理，杀虫剂，昆虫病原微生物，寄生虫和食肉动物。
