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.
