Fluid mechanics is the description of the flow of liquids and gasses.

流体力学是描述液体和气体流动的学。

Fluid mechanics is notoriously difficult, mostly because motions of tiny things like molecules get really complicated really fast.

流体力学 notoriously 难，主要是因为像分子这样微小的东西的运动会变得非常复杂非常快。

Using fluid mechanics you can work out how much lift is generated from an aeroplane's wing, or how aerodynamic a car is.

使用流体力学，你可计算出飞机机翼产生的升力有多大，或者一辆车的空气动力学性能如何。

[Derek] For fluid mechanics, I always expect that you have to keep the Reynolds number the same as in the real world phenomena.

- [Derek] 对于流体力学，我总是希望你必须保持雷诺数与现实世界现象相同。

So the work that we do is combining fluid mechanics with problems that are relevant in health and epidemiology to understand better how pathogens are transmitted.

所我们所做的工作是将流体力学与健康和流行病学相关的问题结合起，更好地理解病原体是如何传播的。

Today, I'm going to tell you a story about one of nature's most extraordinary engineers that pushes the limits of fluid mechanics and bioengineering and arguably solves their No.

今天，我将向您讲述一个关于自然界最杰出的工程师之一的故事，他突破了流体力学和生物工程的极限，并可说解决了他们的第一大难题。

Integral to marine engineering is an understanding of fluid mechanics, how water moves and how things move through water, as well as watercraft propulsion, the mechanisms used to create thrust to move marine vessels through the water.

海洋工程的核心是对流体力学的理解，包括水是如何运动的， 及物体如何在水中移动，还包括船舶推进机制， 即用产生推力使海洋船舶在水中移动的机制。

MUKUL SHARMA: " That's precisely what we were doing, was looking at fluid mechanics, chemistry, and so on… and applying all that knowledge to making hydraulic fracturing process better." " Hydraulic fracturing" is the industry term for fracking.

Mukul SARMA：“这正是我们正在做的事情，研究流体力学、化学等… … 并应用所有这些知识改进水力压裂过程。 ” “水力压裂” 是水力压裂的行业术语。
