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.

蓝色短波不如红色长波传播得远。

It affected longwave radio communications in Earth's ionosphere.

它影响了地球电离层长波无线电通信。

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标准比我们美国更严格。

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

美国防晒霜中，我们最应该注意是它们防护多少致癌长波紫外线。

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。

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。

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标准是防晒霜需要防护中波紫外线，而不一定要防护长波紫外线。

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

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

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，你可以靠这个看到周围散发热量物体，像动物和人类。

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，所以两种波段紫外线你都应该注意防护。

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

瓦诺斯说，测量环境中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。

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探测长波力，奥什希望它让完成银河系普查更进一步。

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，破坏表皮层底部皮肤细胞。

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防晒霜，是可以对这些紫外线有所防护。

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.

通过精确计时来自这些脉冲星信号， 欧洲、北美和澳大利亚团队试图探测由成对超大质量黑洞在遥远星系中心相互绕行时产生长波波纹。
