基本解释

英汉例句

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。
Some results of high energy cosmic ray, such as the zenith angle distribution, the decay length in the air, the energy spectrum and the vertical intensity of hadron and γ-ray have been presented.
由此给出了天顶角分布、大气中衰减长度、积分能谱和垂向流强等，为研究宇宙线超高能相互作用提供了信息。
