zenith angle

基本解釋

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 .
通過等天頂角掃描方法分能段統(tǒng)計(jì)來自蟹狀星云方向的宇宙線事例的超出，10個(gè)能段相對(duì)各自的本底計(jì)數(shù)的超出量平均為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.
利用等天頂角原理，我們發(fā)展了一套分析各向異性的方法，這套方法能夠得到高精度的兩維各向異性天圖。
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.
采用單一參考測量雙向散射分布函數(shù)時(shí)，要求被測試樣與參考標(biāo)準(zhǔn)的入射天頂角必須相同。
