摘要:
本文在模拟数据的基础上,得到了地球大气中宇宙线感生电离产额函数Y的新近似。参数化是使用反非线性问题的解决方案与afxy(分析fx=y)-代码。给出了方法的简短描述。发现的近似是初级质子核,倾斜到70度天顶角。这允许估计直接电离的主要宇宙射线明确。参数化适用于从地面到高层大气的整个大气。发现参数化的几个影响进行了讨论。
英文摘要:
In this work is obtained new approximation for the yield function Y for cosmic ray induced ionization in the Earth atmosphere on the basis of simulated data. The parameterization is obtained using inverse nonlinear problem solution with afxy(analyze fx=y)-code. Short description of the methods is given. The found approximation is for primary proton nuclei, inclined up to 70 degrees zenith angle. This permits to estimate the direct ionization by primary cosmic rays explicitly. The parameterization is applicable to the entire atmosphere, from ground level to upper atmosphere. Several implications of the found parameterization are discussed.
