We know that UVB rays are the rays that cause sunburns.

我们知道中线会造成晒伤。

Radio waves have the longest wavelengths in the electromagnetic spectrum.

无线电在电磁谱中长最长。

But only some protect against both UVB and UVA rays.

但其中只有几种可以护中线和长线。

For decades, FDA regulations required that sunscreens protect against UVB, but not necessarily against UVA.

几十年，美国食品及药物管理局的标准是晒霜需要护中线，而不一定要能护长线。

One to detect short wavelengths, the blues, one to detect medium wavelengths, the greens, and one to detect long wavelengths, the reds.

一个检测短长，蓝色，一个检测中长，绿色，还有一个检测长长，红色。

These are ultrasonic sensors, and that's how we measure wave height and period and direction in the basin.

这些是超声传感器，这就是我们测量盆地中高、周期和方向的方式。

And I had a little AM transistor radio that I'd listened to, you know, the pop music of the day.

我有一台小型中晶体管收音机，我用它听当的流行音乐。

So an image using the shortest wavelength infrared detector is displayed as blue, the medium wavelength one green, and the longest one red.

因此，使用最短长红探测器的图像显示为蓝色，中长显示为绿色，最长长显示为红色。

Jokes aside the film stays true to its setting with Porco feeling very much like a film noir character from the 1920's and 30s.

撇开搞笑的情节，这部动画中鲁克的设定与1920和30年的电影角色还蛮雷的。

UVB light is higher energy and can cause sunburns while UVA penetrates deeper under the skin and can damage skin cells along the bottom layer of your epidermis.

中线能量较高，会造成晒伤。而长线可以穿入皮肤内部，破坏表皮层底部的皮肤细胞。
