英语翻译
The infrared region of the spectrum was first discovered by Sir Frederick William Herschel (1738-1822) in 1800.Herschel was the founder of modern astronomy and discovered Uranus and other heavenly bodies.His son,Sir John F W Herschel (1792-1871) made important contributions to photography - he was the first to note that silver salts would dissolve in sodium thiosulphate,and discovered several printing processes including the blue-print (cyanotype) and chrysotype (gold print).When he heard of that photography had been invented,he went to his lab for a few days and worked out how it could have been done,rather than spending the years it took the other inventors.He also featured notably as a subject,yielding his soul to the probing lens of Julia Margaret Cameron in one of her finest portraits (see link on Herschel above.)
All normal photographic materials are sensitive to X-rays,including those used in airport security devices.The real danger to film - as a BBC film crew found to their cost a few years ago - is from high-powered baggage scanners.Film should never be packed in baggage to go in the hold and airports may allow hand inspection of photographic film.The scanners used for personal inspection are usually film-safe if they insist on scanning it.If you are carrying film,arrive in plenty of time to allow for inspection and also be prepared to remove any film from your camera.Packing films in clear plastic bags may save time.However security procedures are subject to frequent changes,and professionals taking film abroad (particularly in large quantities) are advised to consult their professional organisations for the latest information on taking film through airports etc.
The use of lead-lined bags for carrying film is not generally considered a good idea,as it may mean that scanner operator will 'turn up the volume' in an effort to examine the package.There is no danger to processed film,so if film is readily available at your destination it may be better to purchase and process the film there.

光谱的红外区域由Frederick 威廉Herschel (1738-1822) 先生第一次发现了1800 年.Herschel 是现代天文的创建者和被发现的天王星和其它星球.他的儿子, 对摄影的约翰・F W Herschel 先生(1792-1871) 做的重要贡献- 他是一注意到, 银色盐会溶化在钠thiosulphate 里, 并且发现了几个打印的过程包括图纸(cyanotype) 并且chrysotype (金印刷品) .当他听说摄影被发明了, 他去他的实验室几天和解决了怎么它能做了, 而不是度过岁月它采取其它发明者.他著名地并且以为特色作为主题, 产生他的灵魂对Julia Margaret Cameron 探查的透镜在她最美好的画像的当中一个中(参见链接在Herschel 上面.) 所有正常摄影材料对X-射线是敏感的, 包括那些被使用在机场安全设备里.对影片的真正的危险- 如同BBC 电影工作人员找到对他们的费用几岁月前- 从大功率的行李扫描器.影片应该从未被包装在行李进来在举行并且机场也许允许胶片的手检查.扫描器被使用为个人检查通常是影片安全的如果他们坚持扫描它.如果您运载影片, 到达在大量时刻考虑到检查和并且准备从您的照相机去除任一部影片.包装影片在清楚的塑料袋也许节省时间.但是安全规程是随时频繁变化, 并且专家采取影片海外(特别大量地) 被劝告咨询他们的专业组织对于最新的信息关于采取影片通过机场等. 对lead-lined 袋子的用途为运载影片一般不被认为一个好想法, 因为它也许意味扫描器操作员意志'turn 上升volume' 在努力审查包裹.没有危险对冲洗胶片, 因此如果影片是欣然可利用的在您的目的地它也许是更好购买和处理影片那里. 光谱的红外区域由Frederick 威廉Herschel (1738-1822) 先生第一次发现了1800 年.Herschel 是现代天文的创建者和被发现的天王星和其它星球.他的儿子, 对摄影的约翰・F W Herschel 先生(1792-1871) 做的重要贡献- 他是一注意到, 银色盐会溶化在钠thiosulphate 里, 并且发现了几个打印的过程包括图纸(cyanotype) 并且chrysotype (金印刷品) .当他听说摄影被发明了, 他去他的实验室几天和解决了怎么它能做了, 而不是度过岁月它采取其它发明者.他著名地并且以为特色作为主题, 产生他的灵魂对Julia Margaret Cameron 探查的透镜在她最美好的画像的当中一个中(参见链接在Herschel 上面.)
