sky angle

As a large number factors affect ocular UV exposure, including the solar elevation angle, altitude, ground reflection, sky scattering and facial anatomy etc, so individual ocular UV exposure quantification has been severely limited for a long time.

由于眼部紫外线暴露的影响因素较多，包括太阳高度角、海拔、地面反射、天空散射和面部解剖特征等，因此长期以来，个体眼部紫外线暴露的定量一直受到较大的限制。

Based on the results of the contrast of star to sky background in daytime, the detectable stellar magnitude limits are computed and analyzed as functions of observing heights, solar zeniths angle, wavebands and stellar spectral types for 3 °× 3 ° field of view.

根据恒星和白天大气背景辐射的对比度，计算和分析了3°×3°视场下，可探测星等极限值随观测高度、太阳天顶角、波段和恒星光谱类型的变化情况。

Daily variations of UV B radiation are greatly controlled by the solar zenith angle ( SZA), ozone and the sky conditions.

云和太阳高度角控制着UV－B辐射通量日变化过程。

The angle like flying bird. the ideas from dreaming just like dream on the sky.

这些天使如同飞翔的鸟儿, 而这组创意来自于梦境,仿佛幻景中的天堂.

When Google Sky, users viewing angle of the whole world changed.

当进入GoogleSky之后，使用者观看世界的角度全变了。
