鱼类学

A new bionics propulsion equipment—fishlike flexible tail fin propulsion equipment is brought forward,because there are some problems in present thrusters,such as big noise,low propulsion efficiency in shallow water and evident wake.

本文针对现有船用螺旋桨、泵喷等常规推进器存在噪音大、浅水中船舶推进效率不高以及尾迹明显等缺点，提出一种新型仿生推进装置—仿鱼尾柔性尾鳍推进装置，并据此展开了对单翼板柔性尾鳍和双翼板柔性尾鳍模型的计算和实验研究，本文工作属于鱼类生物流体力学、机械学、材料学和控制技术等多学科交叉的一个新兴研究领域。

The recent studies on comparative genomics have further suggested that a third round of fish-specific genome duplication in ray-finned fishes might have occurred at about 350 million years ago, during the divergence between teleost fish and basal actinopterygian lineages. Therefore, FSGD might be related to the increase in species number and biological diversity during this time.

近期的系统基因组学研究资料进一步提出，在大约350百万年，辐鳍鱼还发生了第三次基因组复制，即鱼类特异的基因组复制(fish-specific genome duplication， FSGD)，且发生的时间正处在"物种极度丰富"的硬骨鱼谱系和"物种贫乏"的谱系出现分歧的时间点，表明FSGD与硬骨鱼物种和生物多样性的增加有关。
