The basic three-ball pattern was a cascade, juggling the balls in a circle was a shower, and throwing one ball over the top was a half-shower. 三个球的基本花样叫层叠,将球抛成一个圆圈叫簇旋,将一只球抛得最高叫半簇旋。
Some models of estimating the starting point of atmospheric electromagnetic cascade shower(ⅰ) 估计大气电磁级联簇射起始点位置的几种模型(Ⅰ)
On the basis of expedient equation of three-dimensional electron-photon cascade shower development in emulsion chambers, a calculation has been made of the relation D-E-t among the spot darkness, shower energy and depth, Practical application procedures are summarized and discussed. 在简单的三维电子光子级联理论方程(乳胶室观测用)的基础上计算了在x光片上簇射黑斑黑度和能量的关系DEt,并介绍了应用的方法。
