水黾为何能在水面上行走如飞?。

Unit 38 Why Can Water Striders Walk Smoothly on Water?

为了感谢你，我送给你我最新的发明：“水黾之鞋”。

To thank you, I present you with my latest invention: waterbug shoes.

水黾可以在水面上停留并具有快速滑行和跳跃的活动机能。

Water strider is a kind of insect that has the active function of staying, sliding and leaping on water surface.

一些昆虫，比如长腿水黾与水面保持一定距离，利用空气垫在水面滑行。

Some, like long-legged water striders, maintain a small measure of distance from the water with a cushion of air that lets them skate on the surface.

受水黾启发，人们对在水面这一非结构环境下能快速移动的仿水黾机器人的研究产生了浓厚兴趣。

Enlightened by this kind of insect, people become more and more interest on the water strider robot, which can move fast on the unstructured water surface.

水上行走机器人的研究是基于仿生原型水黾能够在水面上行走的基本原理而开展的一种新型仿生机器人研究。

The research on robot walking on water surface is developing a novel bionic based on the basic principle that water strider can walk on water surface.

我们小组从生物界获取灵感，研究了大量相关流体力学问题，比如蜗牛如何运用黏液进行移动、水黾如何在水上行走。

"Our research group studies a lot of biologically inspired fluid mechanics problems, such as how snails use slime for locomotion, or how water striders walk on water, " Nasto says.

仿生机械水黾的特性研究和实现是基于仿生原型水黾能够在水面上行走的基本原理而开展的一种新型仿生机器人研究和设计。

The characteristic research and realization on bionic mechanical water strider is developing a novel bionic based on the basic principle that water strider can walk on water surface.

研究了大型授油机尾流的形成和分布特点，分析了受油机在不同位置进入黾流时飞机所受的影响，提出了相应的数学建模方法。

The formation and distribution of wake flow behind a large aerial tanker are discussed, Then the mathematic model of disturbance to the refueled aircraft during refueling is given.

一只美洲鳄从晚间的睡梦中醒来，离开海黾草的床铺，返回红树林根系盘结成的迷宫，那里是外来者几乎不可能穿行的藏身之所。

An American crocodile rises from a bed of turtle grass to return to the labyrinth of mangrove roots that offer near-impenetrable shelter.
