Therefore it is of significance to research on the relationship between atmospheric temperature and earthquake, as has been reported. A preliminary analysis on the data collected in Yunnan Province shows that there exists an obvious relationship between the atmospheric temperature anomaly and a great展开更多

From September to October 1981, the experiment of remote sensing on atmosphere was carried out at Peking University with 5 mm—1.35 cm band 4-channel radiometers. In this note, we present and discuss the experimental results from 8 mm to 1.35 cm radiometers of remote sensing atmospheric water vapor content and the characteristics of absorption in λ=1.35 cm water vapor band and λ=8 mm window band. In these bands, the microwave absorption of atmosphere is small, much smaller展开更多
当玻璃外壳搭配金属机械机芯,用手工艺与艺术把坚固的金属与澄澈的水晶玻璃融为一体,化无形为有形,连接着人、环境与永恒的时间。积家的Atmos空气钟构造在1928年就已经震惊世界。这个无需任何外力的钟,根据巧妙的设计,能把气温转成动力...当玻璃外壳搭配金属机械机芯,用手工艺与艺术把坚固的金属与澄澈的水晶玻璃融为一体,化无形为有形,连接着人、环境与永恒的时间。积家的Atmos空气钟构造在1928年就已经震惊世界。这个无需任何外力的钟,根据巧妙的设计,能把气温转成动力。其奥秘在于一个充满混合气体的密封罩,气体根据温度的细微变化膨胀或收缩,不断为座钟上链,一摄氏度的温差可以产生支持48小时运转的动力。爱马仕委托Les Cristalleries de Saint-Louis制造空气钟超凡的水晶玻璃罩。展开更多
