But only some protect against both UVB and UVA rays.

但其中只有几种可以同时防护中波紫外线长波紫外线。

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

几十年来，美国食品及药物管理局的标准是防晒霜需要防护中波紫外线，而不一定要能防护长波紫外线。

Radio waves have the longest wavelengths in the electromagnetic spectrum.

无线电波在电磁波谱中波长最长。

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

我们知道中波紫外线会造成晒伤。

That is how waves look in a double split experiment.

那是缝实中波的样子。

Most cars, for example, have both FM and AM radios.

大多数汽车都配备了调频中波收音机。

And I would argue that Chainsaw Man's, Pochita's devil powers are very significant.

我可以说，《电锯人》中波奇塔的恶魔之力极为重要，威力非凡。

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

一个检测短波长，蓝色，一个检测中波长，绿色，还有一个检测长波长，红色。

There are two basic kinds of radio, FM and AM. " FM" stands for " frequency modulation."

有两种基本的广播类型， 调频中波。 " FM" 代表" 频率调制" 。

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

这些是超声波传感器，这就是我们测量盆地中波高、周期的式。

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，使用最短波长红外探测器的图像显示为蓝色，中波长显示为绿色，最长波长显示为红色。

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

我有一台小型中波晶体管收音机，我用它来听当时的流行音乐。

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，这部动画中波鲁克的设定与192030年的电影角色还蛮雷同的。

I have an old car, and my car definitely has AM and FM radio, although I don't listen to either one.

我有一辆旧车， 我的车肯定有调频中波收音机，虽然我两个都不听。

Red light has the longest wavelengths in the visible spectrum, and so can safely penetrate deeper into the skin than light with shorter wavelengths.

红光在可见光谱中波长最长，因此相较于波长较短的光，它能更安全地深入皮肤。

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.

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

Lacking M cones that react to medium wave light, he could only distinguish between two or three colours, rather than the full spectrum visible with normal vision.

由于缺乏对中波长光线敏感的M锥体细胞，他只能分辨出两到三种颜色，而非正常视力下所能感知的完整光谱。

And that telescope would have the same power as a Hubble telescope, you know, size telescope could have, because the signals that we're looking for are enormous in wavelength on the sky.

因此，这台望远镜的性能将与哈勃望远镜相当，你知道，就其尺寸而言， 哈勃望远镜所能达到的威力，因为我们在天空中寻找的信号波长极其巨大。 它们是天空中波长极长、覆盖范围广阔的信号。
