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

我们知道中紫外线会造成晒伤。

But only some protect against both UVB and UVA rays.

其中只有几种可以同时防中紫外线和紫外线。

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防晒霜需要防中紫外线，而不一定要能防紫外线。

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，蓝色，一个检测中，绿色，还有一个检测，红色。

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，使用最短红外探测器的图像显示为蓝色，中显示为绿色，最显示为红色。

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同的。

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.

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