And it has a radar device. It has this long-wave radar.

它有一个雷达设备。它有这种长波雷达。

The short-wave lengths of blue don't travel as far as the long red wave length.

蓝色的短波不如红色的长波传播得远。

It affected longwave radio communications in Earth's ionosphere.

它影响了地球电离层的长波无线电。

Here in the United States, I think we need to be cognizant of the fact that when a sunscreen says it's broad spectrum, UVA-and UVB-protecting, that does mean you're going to get protection against those rays.

在美国，我想我们要意识到这样一个事实，就是写有广谱防晒、防中长波紫外线这样的防晒霜，是可以对这些紫外线有所防护的。

Then you have, also, long-wave infrared where you are able to see agents that are emitting heat, such as animals and humans.

就是还有长波红外线，你可以这个看到周围散发热的物体，像动物和人类。

And with its more powerful ability to probe long wavelengths, Oesch is hoping it might bring our galactic census a little closer to completion.

詹姆斯·韦伯空间望远镜拥有更强大的探长波的能力，奥什希望它能让完成银河系普查更进一步。

Vanos said measuring short- and long-wave radiation in the environment can tell researchers how much a surface will heat up during the day.

瓦诺斯，环境中的短波和长波辐射可以告诉研究人员一个表面在白天会升温多少。

In Europe, there are nine UV filters for UVA light. Here in the United States, we only have four.

在欧洲，有9种紫外线防晒剂可以过滤长波紫外线。在美国，只有4种。

And while this is a good first step, there's still no regulation on how much protection you're getting from UVA.

虽然这是一个好的开端，但是对于长波紫外线应该有多强的防护，美国食品及药物管理局还是没有给出相关规定。

However, their standards for UVA filter approval is more robust than what we have here in the United States.

然而，欧洲对长波紫外线防晒剂的认证标准比我们美国更严格。

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和长波紫外线。

The biggest concern with US sunscreen is how much protection you're getting from cancer-causing UVA rays.

美国的防晒霜中，我们最应该注意的是它们能防护多少能致癌的长波紫外线。

But UVA rays are the rays that can actually cause skin cancer so you actually wanna cover the spectrum on both of those.

但长波紫外线则可以引发皮肤癌，所以两种波段的紫外线你都应该注意防护。

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。

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。

You know short waves carry more energy than long ones.

你知道短波比长波携带的能更多。

Relatively short wavelengths of light, medium wavelengths and long.

相对较短的光波、中等波长以及长波。

By precisely timing the signals from these pulsars, teams in Europe, North America and Australia seek to detect long-wavelength ripples produced by pairs of supermassive black holes as they orbit each other at the centres of distant galaxies.

过精确计时来自这些脉冲星的号， 欧洲、北美和澳大利亚的团队试图探由成对的超大质黑洞在遥远星系中心相互绕行时产生的长波波纹。

But if we are looking at long waves, long waves are going to be diffracted more readily and so they are not going to experience that problem.

但如果我们观察的是长波，长波更容易发生衍射， 因此它们不会遇到这个问题。

Basically, this aerosol cloud, quote, scattered short-wave solar radiation back into space, while allowing much of the long-wave radiant heat from the Earth to escape.

基本上，这种气溶胶云，引用一下，将短波太阳辐射散射回太空，同时让地球大部分的长波辐射热得以逃逸。
