Because of sharing characteristics with both Galliform groups, Tragopans are classified as partridges by some authors and pheasants by some others. In this study we set out to sequence the cytochrome b-gene of 19 species pheasants. and took the sequence for those 22 species from GenBank. We amplified 828 base pairs using the PCR technique. Primers designed by ourselves were based upon Galliform sequence data. Neighbor-joining method and Minimum evolution method were used to analyse cytochrome b sequences with Anhima cornuta and Kachuga dhongoka as outgroups.
通过PCR扩增鸡形目Galliformes黄腹角雉Tragopan caboti等10个属19个个体的线粒体DNA细胞色素b的部分基因,获取片段长度为828bP,以及从GenBank获取22种样本的相应序列,以角叫鸭Anhima cornuta和海龟Kachuga dhongoka为外群,分别用邻接法(Neighbor-joining, NJ)和最小进化法(Minimum-evolution, ME),对鸡形目和将雉科的15个属分为5个属及雉族和鹑族构建分子系统树,NJ和ME系统树中,都是角雉与雉类相聚。

The sand fixed hedge has been using at Taiwan's coastally, how is the best desing for different from angle between main hedge and wing hedge, it is still no results. In this study, there are two part of experiment that are field study and wind tunnel. The field study is analysis by BSNE sand sampler and multi-layer anemometer at Yuanli coastally, the wind tunnel experimental that study different length and angle of hedge.
中文摘要堆砂篱於台湾沿海虽已被广泛使用,然堆砂篱是否需要大面积全面铺设,才能获得最显著功效;主篱与翼篱之间夹角应如何规划,才能达到最佳化设计,至今尚无具体结果,为能深入探讨本研究分为现地及风洞试验,现地试验以苑里沿海为试区,架设BSNE垂直集砂器及多层风速计等进行观测;风洞试验则依翼篱长度与角度从事模型吹砂试验。

Firstly the properties of L-MAX frequent itemsets is analysed.Then by extending FP-tree structure an ExFP-tree data structure is presented and the algorithm of ExFP-tree generated is given.According to the character of prefixing paths shared in FP-tree,ExFP-tree implements compressingly storage of transaction information with sharing the transaction information of descendant nodes.
ExFP-tree利用FP-tree共享前缀路径的性质通过共享子孙节点事务信息策略实现大量事务信息的压缩存储;最后基于FP-MAX算法,提出基于ExFP-tree的L-MAX频繁项集挖掘算法,核心思想是先根据L-MAX频繁项集长度约束性质进行前瞻剪枝再进行最大频繁项集挖掘,并通过回溯策略直接定位生成对应事务集。
