EAS次级粒子分布的抛物面模型

A PARABOLIC MODEL OF COSMIC RAY SHOWER FRONT

提出一个旋转抛物面模型,用于描述宇宙线簇射次级粒子的分布曲面。这一模型较之于常用的平面模型更接近于粒子的实际分布情况,其有关参数可由阵列出观测结果推出,从而为使用小阵列探测大簇射提供了一条可能的途径。

A parabolic shower front is given here and it is better than the plane model which is usurely used. All the parameters of the parabola can be derived from the data recorded by a cosmic ray air shower array. So that this model gives a possible way to reach the goal of using a small array to detect big showers.
