Hanke says the weak U. s. dollar does not help matters.

汉克说，美元贬值对问题不会有帮助作用。

The study was led by Wolf Hanke of the Marine Science Centre at the University of Rostock, Germany.

这项研究是由德国罗斯托克大学海洋科学中心的伍尔夫·汉克所领头开展的。

"Electroreception is good for sensing prey over short distances, where echolocation isn´t so effective," says Hanke.

汉克表示：“电感知能力有利于在近距离内感觉到猎物的存在，因为此时回声定位感已不那么灵敏。”

“It´sa question of the policy and the thinking catching up with the technology, ”says Mr Hanke. “Ease of access alters the debate.”

“这是政策和追赶新技术的想法的问题”汉克先生说，“方便访问改变了争论。”

Dr Hanke and Mr Wieskotten then tested Henry with the wakes of paddles of different shapes: triangular, cylindrical, flat and undulating.

汉克博士和威斯·科顿接着会使用不同形状的桨——三角形、圆柱形、平板形以及波浪形——的尾流对亨利进行测试。
