zenith angle

基本解释

Cosmic rays excess from the direction of Crab Nebula for different energy bands with equi-zenith angle method is searched and the mean excess for 10 energy bands is 1. 14o .
通过等天顶角扫描方法分能段统计来自蟹状星云方向的宇宙线事例的超出，10个能段相对各自的本底计数的超出量平均为1.14。
Based on the equi-zenith angle method, this work has developed a new analysis method which allows the two-dimensional and high precision anisotropy measurement possible for the first time.
利用等天顶角原理，我们发展了一套分析各向异性的方法，这套方法能够得到高精度的两维各向异性天图。
When using a single reference to measure the bi-directional scattering distribution function (BSDF), the incident zenith angle of the tested sample must be identical to that of the reference.
采用单一参考测量双向散射分布函数时，要求被测试样与参考标准的入射天顶角必须相同。
