中國網浪潮新聞訊  一種“魚”身長20多釐米，渾身柔軟無骨，能穿過水底狹窄的縫隙，還能以每秒12釐米的速度巡航，遇到緊急狀況還能將速度提升一倍多。按距離身長比來計算的話，竟然有比菲爾普斯遊的還溜”，這究竟是一種什麼魚？

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?

　　在浙江大學航空航太學院的實驗室裏，幾條微縮版的“蝠鲼”(俗稱魔鬼魚)正在水中漫遊，這種魚的名字叫做軟體機器魚，據它的創造者——浙江大學航空航太學院副教授李鐵風介紹，目前軟體機器魚已是第四個版本，和之前的幾個版本相比，這個版本的軟體機器魚個頭更大，速度更快，信號的傳輸距離也更遠。

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.

　　和普通的水下機器人通過螺旋槳等水下驅動器提供動力不同，李鐵風研發的軟體機器魚的運作方式和真正的蝠鲼很相似。“它有電子肌肉。”李鐵風指著它柔軟的“肚皮”説，這是機器魚的核心部件。這一層薄薄的 “電子肌肉”，實際上由三層材料組成，上下兩層是透明的介電高彈體薄膜，中間是導電用的碳膏或水凝膠；三層材料緊密地粘合在一起，就像北京著名小吃“茯苓餅”。如果給它兩極通上交流電，它已經可以像心臟一樣地“跳”動了。

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.

　　據他介紹，這種機器魚能做的不僅是觀賞，還能完成不少和水下勘測有關的工作，在收集水文資料和沉船打撈的前期探測也能發揮作用。事實上，水下機器魚的作用正越來越明顯，業內人士表示，水下環境比較複雜，利用水下機器魚代替人們下水探測，既能降低勘察人員的危險系數，還能簡便地獲取豐富的數據，可謂一舉兩得。

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.
