中国网浪潮新闻讯  一种“鱼”身长20多厘米，浑身柔软无骨，能穿过水底狭窄的缝隙，还能以每秒12厘米的速度巡航，遇到紧急状况还能将速度提升一倍多。按距离身长比来计算的话，竟然有比菲尔普斯游的还溜”，这究竟是一种什么鱼？

CNCAO NEWS A "fish",the length is more than 20 centimeters,the body is soft like no bones,can pass through a narrow gap in the water,but also cruise at a speed of 12 centimeters per second,can also speed up more than doubled in an emergency situation.According to distance length ratio,even swim faster than Phelps,what kind of fish is this?

　　在浙江大学航空航天学院的实验室里，几条微缩版的“蝠鲼”(俗称魔鬼鱼)正在水中漫游，这种鱼的名字叫做软体机器鱼，据它的创造者——浙江大学航空航天学院副教授李铁风介绍，目前软体机器鱼已是第四个版本，和之前的几个版本相比，这个版本的软体机器鱼个头更大，速度更快，信号的传输距离也更远。

In the laboratory of the College of Aeronautics and Astronautics, Zhejiang University,several miniature version of "Manta ray"(Commonly known as the devil fish),were swimming in the water,this fish is known as the software robot fish,according to its creator——Li Tiefeng, associate professor, School of Aeronautics and Astronautics, Zhejiang University,at present, the software robot fish is the fourth version,compared with previous versions,this version of the software robot fish is bigger and faster,and the transmission distance of the signal is also farther.

　　和普通的水下机器人通过螺旋桨等水下驱动器提供动力不同，李铁风研发的软体机器鱼的运行方式和真正的蝠鲼很相似。“它有电子肌肉。”李铁风指着它柔软的“肚皮”说，这是机器鱼的核心部件。这一层薄薄的 “电子肌肉”，实际上由三层材料组成，上下两层是透明的介电高弹体薄膜，中间是导电用的碳膏或水凝胶；三层材料紧密地粘合在一起，就像北京著名小吃“茯苓饼”。如果给它两极通上交流电，它已经可以像心脏一样地“跳”动了。

And it is different from the ordinary underwater robots,which are powered bypropeller and other underwater drive.The operationmode of the software robot fish,developed by Li Tiefeng is similar with the real Manta ray."It has electronic muscles."Li Tiefeng pointed to its soft "belly" and said,this is the core of the machine fish.This layer of the thin "electronic muscles",actually consists of three layers of material,the upper and lower two layers are transparent dielectric elastomers film,the middle is a conductive carbon paste or hydrogel;the three layers of material are bonded together,like Beijing famous snack "Poria cake".If its two poles on the alternating current,it has been able to "jump" like the heart.

　　据他介绍，这种机器鱼能做的不仅是观赏，还能完成不少和水下勘测有关的工作，在收集水文资料和沉船打捞的前期探测也能发挥作用。事实上，水下机器鱼的作用正越来越明显，业内人士表示，水下环境比较复杂，利用水下机器鱼代替人们下水探测，既能降低勘察人员的危险系数，还能简便地获取丰富的数据，可谓一举两得。

According to his introduction,this machine fish can not only for people to watch,but also to complete a lot of work related to underwater survey,it also play a role in the collection of hydrological data and the early detection of salvage.In fact,the function of underwater machine fish is becoming increasingly apparent,industry insiders said,underwater environment is complex,use underwater machine fish instead of people into the water detection,which can reduce the risk factor of survey personnel,but also can easily access to rich data,it can be described as two birds with one stone.
