棱镜

In this paper, the experimental results of an unidirectional operation laser, includins input-output curve, the power ratio of the two oppositely travelins waves under different coupler transittunces and pump levels, the tuning characteristics with a prism in the external cavity, and the narrowing of the output spectrum with etalons, are given.

In 1839, a group of fur trappers from the American Fur Company crossed the Midway Geyser Basin and made note of a "boiling lake", most likely the Grand Prismatic Spring, with a diameter of 300 feet (91 m).

1839年，休渔的毛皮，从美国毛皮公司集团跨越中途岛间歇泉盆地，使之成为一个&沸腾湖&中，最有可能的大棱镜春天，300英尺（91米）直径。

They form when the sun is near the horizon and ice crystals high in the sky line up in a way that bends the solar rays like a prism.

在太阳靠近地平线并且高空中的冰晶排列成一种能像棱镜般折射阳光的形式时，幻日现象便形成了。

They form when the sun is near the horizon and ice crystals high in the sky line up in a way that bends the solar rays like a prism.

当太阳靠近地平线，并且天空里的冰晶达到一定高度后就象棱镜一样折射太阳光线时，就会出现这种幻日现象。

They form when the sun is near the horizon and ice crystals high in the sky line up in a way that bends the solar rays like a prism.

幻日是在极区较常见的大气现象，由於太阳位於地平线位置，天空中的冰晶体会担当棱镜的角色把太阳光扭曲。
