※ 引述《haryewkun (Har)》之铭言： : 请问，外太空的紫外线，平均比大气层内的紫外线，强多少倍？ : 有这方面的资料吗？ : 至於外太空的范围，应该是限制在地球到月球之间的距离，既不会跑到水星 : 那麽靠近，也不会跑到木星、土星以外那麽远。 : 至於大气层内，则是限制在一般人生活的地面（海拔零），不包括那些臭氧 : 层有破洞的地方，也不包括高空。 : 或者说，要开发太空船去月球，大概要考虑抵御多强的紫外线及辐射？ : 上网搜索，有人说是一万倍，不知道这个数字有没有水分…… 自己回自己……在wikipedia的Ozone layer找到的资料： - UV radiation is divided into three categories, based on its wavelength; these are referred to as UV-A (400-315 nm), UV-B (315-280 nm), and UV-C (280-100 nm). - UV-C, which would be very harmful to humans, is entirely screened out by ozone at around 35 km altitude. - UV-B radiation can be harmful to the skin and is the main cause of sunburn; excessive exposure can also cause genetic damage, resulting in problems such as skin cancer. - The ozone layer is very effective at screening out UV-B; for radiation with a wavelength of 290 nm, the intensity at Earth's surface is 350 billion times weaker than at the top of the atmosphere. - Most UV-A reaches the surface; 看到这个数据被吓到了：UV-B是对人体皮肤有害的，而它在太空的强度是地 球上的三千五百亿倍？ 如果是这样，那些在太空中漫游的太空人怎麽办？太空服足够抵挡吗？ -- +-----------------------------------------------------------------+ | 夏之星系 - 个人日志，提供佛学命理、小说漫画、娱乐、技术等内容。 | | http://xia4.org | +-----------------------------------------------------------------+ --
