The alligator gar of the southern U.S. reaches a length of about 10 ft (3 m) and is one of the largest freshwater fishes

产于美国南部的钝吻鳄雀鳝长约3公尺，是淡水鱼中最大的种之一。

Landed 72 Bass, but also caught a bunch of other fish I had only ever caught on the playstation (Sunfish, Oscar, Alligator Gar, Bluegill, Stumpknocker) etc.

共钓上了72尾 Bass，而且亦钓上一些其他是我只可在游器机如playstation (翻车鱼，奥斯卡，鳄鱼雀鳝，大翻车鱼， Stumpknocker)看见的鱼。

Gymnothorax genus belongs to Muraenidae family(Osteichthyes:Anguillomorph -a:Anguilliformes),which are widely distributed throughout the tropical and subtropical oceans,and are inhabited in coral reefs.But the molecular phylogeny of Gymnothorax are not studied.

裸胸鳝属鱼类隶属硬骨鱼纲鳗鲡总目鳗鲡目海鳝科，是广泛分布于热带和亚热带的岩礁鱼类，目前国内外对裸胸鳝属鱼类的分子系统学研究远远落后于其它生物类群。

However, the food composition of the M. albus with body length more than 100mm were quite consistent, with Chironomidae, Oligochaeta, Pheretima, Cladocera, Copepoda and insect larvae as the major food items.

而全长101-200mm的幼鳝及全长大于200mm的成鳝的食性，随全长变化相对稳定，且幼鳝和成鳝的食谱基本相同，其主要食物组成均包括摇蚊幼虫、水生寡毛、蚯蚓、昆虫幼虫、枝角类和桡足类等。

The phylogenetic analysis of Gymnothorax was reported in this paper by being based on DNA sequences of mitochondrial Cytb gene.17 species of Cytb gene full-length sequences were obtained and their length of Cytb gene was 1140bp.All sequences were analysised by using biological software, the phylogenetic tree was constructed by using three kinds of common contribution phylogenetic tree methods and the phylogeny of 17 species of Gymnothorax was deduced.

本论文采用线粒体Cytb基因为分子标记，共获得裸胸鳝属鱼类17种Cytb基因序列全长为1140bp的部分序列，应用分子生物学软件对结果进行分析，使用3种常见的建树方法：NJ法、ME法和MP法重建系统发育树，对裸胸鳝属17种鱼类的系统关系进行研究，为探讨裸胸鳝属鱼类的分子进化，确定它们之间的关系提供分子生物学方面的证据。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
