雅库茨克资料在能量5 ~ 10^{17}~ 3 ~ 10^{19} ev范围内X_（max）和初级粒子质量组成的起伏
Fluctuations of Xmax and Primary Particle Mass Composition in the Range of Energy 5 10^{17} - 3 10^{19} ev by Yakutsk Data
摘要：
本文分析了在固定能量为$5 \times10^{17}$、$1\times10^{18}$和$5\times10^{18}$ eV时，用雅库茨克EAS阵列获得的$\Xmax$的实验分布。最新版本的QGSJET模型被用作我们的分析工具。在此模型框架内，选择了最适合于$\Xmax$实验数据的初级粒子质量组成。
英文摘要：
The experimental distributions of $\Xmax$ obtained with the Yakutsk EAS array at fixed energies of $5 \times10^{17}$, $1\times10^{18}$ and $5\times10^{18}$ eV are analysed. A recent version of the QGSJET model is used as a tool of our analysis. In the framework of this model, the most adequate mass composition of primary particles satisfying the experimental data on $\Xmax$ is selected.
