In this work, the effects of extensive air showers (EASs) were described by estimating the lateral distribution function (LDF) at very high energies of various cosmic-ray particles. The LDF simulation was performed using the air shower extended simulation (AIRES) system version 2.8.4a. LDF was simulated for charged particles such as pair production, muons, and all charged particles at very high energies (10¹⁶, 10¹⁸, and 10¹⁹ eV). The effect of primary particles, energies, and zenith angle (θ) on the LDF of the charged particles produced in the EAS was taken into account. The LDF simulation of the charged particles was compared with the experimental results and found to be in good agreement with the pair production and muon particles in energies of 10¹⁸ and 10¹⁹ eV for θ = 10°. LDF parameterization of charged secondary particles (electrons and positrons) and secondary muon particles, initiated by primary proton and iron nuclei at the energy 10¹⁹ eV, was performed. On the basis of this simulation, sets of approximating functions for primary protons and iron nuclei for vertical showers were obtained.

在这项工作中，通过估计各种宇宙射线粒子在非常高的能量下的横向分布函数 (LDF)，描述了广泛的空气簇射 (EAS) 的影响。LDF 模拟是使用空气淋浴器扩展模拟 (AIRES) 系统版本 2.8.4a 进行的。LDF 模拟了带电粒子，例如对产生、μ 子和所有处于非常高能量（10 ¹⁶、10 ¹⁸和 10 ¹⁹  eV）的带电粒子。初级粒子、能量和天顶角 ( θ) 在 EAS 中产生的带电粒子的 LDF 被考虑在内。将带电粒子的 LDF 模拟与实验结果进行比较，发现在θ = 10° 时，其与能量为 10 ¹⁸和 10 ¹⁹  eV的对产生和介子粒子非常吻合。进行了带电二次粒子（电子和正电子）和二次 μ 子粒子的 LDF 参数化，由一次质子和铁核在能量 10 ¹⁹  eV 下引发。在此模拟的基础上，获得了垂直簇射的初级质子和铁核的近似函数集。
