斑蝶

Total genomic DNA was extracted from four marine fishes (Verasper variegates, Cleisthenes herzensteini, Turbot Scophthalmus maximus, red seabream Pagrosomus major) using a proteinase K and phenol-chloroform procedure. Long mtDNA fragments were amplified by long and accurate PCR using primers designed based on the mtDNA sequenses of Thunnus thynnus thynnus, flounder Paralichthys olivaceus and other related fishes.

用蛋白酶k酚氯抽提法从圆斑星鲽、高眼蝶、大菱鲆和真鲷4种海水鱼的肌肉组织中提取基因组DNA，根据金枪鱼、牙鲆及相关鱼类的线粒体DNA序列保守片断设计出扩增引物，扩增从16SrRNA到ND4之间约9400bp的mtDNA长片段。

By this study, we figure out the patterns on the butterfly wings can be classified into two types, global patterns belong to the background, and local eyespot patterns according to the wing cell midline, furthermore, our study simulates these patterns by computer simulation.

本研究能模拟出蛱蝶科中具有同心圆眼斑以及沿著翅膀边缘上分布之波浪花纹，另外也能模拟分布於翅膀全域较小较无规则的波浪斑纹；藉由本研究我们发现蝶翅斑纹可以分为属於背景的全域斑纹与以翅室中线为准属於区域性的眼斑花纹，而本研究皆能分别以电脑模拟出来。

Using Parantica aglea and Euploea core as the outgroups, the phylogenetic trees of the Nymphalidae taxa in this study were reconstructed with and Bayesian methods based on 16S rDNA, 12S rDNA and their combined sequences. The results showed that the Nymphalinae was not monophyletic; the Junonia should be classified into Hypolimni; the Apaturinae, Byblinae and Nymphalinae were closely related to each other; the Pseudergolinae and Byblinae should be separated from Limenitinae.

分子系统树显示：蛱蝶亚科并非单系群，蛱蝶族中眼蛱蝶属应移入斑蛱蝶族；豹蛱蝶亚科为单系发生；闪蛱蝶和苾蛱蝶亚科与蛱蝶亚科具有较近的系统关系；支持将秀蛱蝶和苾蛱蝶亚科从线蛱蝶亚科中分离出来。

Phylogenetic and molecular evolutionary analyses of 13 mitochondrial coding genes conducted using MEGA version 3.0 showed that all the pleuronectiform species except for soleid species which had close phylogenetic relationship with perciformes and the soleid species had far evolutionary relationship with all other fish species. These new data provide a useful tool for many research areas, i. e. evolutionary study and identification of spotted halibut.

用NJ法和MP法对5个目22种鱼mtDNA的13个蛋白质编码基因的氨基酸序列进行系统分析，结果显示，圆斑星蝶与石鲽关系最近，鲽形目的鲆、鲽类与鲈形目的够科、鲷科鱼类亲缘关系较近，而同属于鲽形目的塞内加尔鳎没有和任何目聚在一起，成为一个独立的分支。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
