A small westerly offshore breeze, drawing the hot land air out to sea, had risen and was piling up wavelets that scrolled in, whitely, as far as the eye could see.

一股微西向离岸风， 正将陆地上热气引向海面，风势渐起，堆积起层层浪， 这些浪花翻滚着，白花花地一直延伸到目力所及之处。

He'd have watched for telltale wavelets, odd little eddies in the water that marked places of danger or deeper channels.

他会留意那些预示着危险或深水通道微波纹和水中奇怪小漩涡。

There was a brisk breeze blowing and the sea looked playful, with white wavelets dancing across the horizon.

微风吹拂，大海显得俏皮，白色波浪地平线上翩翩起舞。

Finally, you draw a curve that's tangent to each wavelet, meaning that it touches each half circle at exactly one point.

最后，绘制一条与每个小波相切曲线，这意味着它一个点接触每个半圆。

But the part that isn't blocked keeps moving past the edge, and it follows Huygens' principle, forming wavelets.

但是没有被阻挡部分会一直移动到边缘之外，它遵循惠更斯原理，形成小波。

Each of those little half-circles is called a wavelet.

这些小半圆中每一个都 称为小波。

The wavelets from the part of the wave near the edge will curve behind the edge.

来自靠近边缘部分波小波 将边缘后面弯曲。

And when you draw a line to connect all the wavelets, you end up with a line that bends around the edge.

当你画一条线来连接所有小波时，你最终会得到一条围绕边缘弯曲线。
