在影响海洋结构物设计的海洋环境动力因素如风、海浪、海流和海冰等中，通常海浪是最重要的。

Usually, wave is the most important in the effect of oceanic environmental factors on coastal and offshore structural design.

波浪向近岸传播的过程中由波浪破碎等效应所形成的近岸波流场是近岸缓坡区域重要的环境动力因素之一。

The near-shore wave-current field formed by the breaking of oblique incident wave is numerically simulated by applying the mild slope equation for describing the wave propagation in coastal zone.

So clear sense of your core competence and direction, intelligence and understanding not only with your own people are doing but what's going on in academia and in startups, and then the willingness to take some risk that would be what I'd say.

清楚的了解你的核心竞争力和方向，才干，并了解你的伙伴在做什么,以及学术环境和创业环境的发展，然后要有冒险的动力,这就是我要讲的。
