  • Abstract
In the research of super-high energy nuclear interaction induced by cosmic rays with emulsion chamber at high mountain,it is very difficult to accurately estimate the starting point of atmospheric electromagnetic cascade shower(i.e,the height of producing family).This paper introduces some ways that are used to estimate the height of producing family and their physical models as well as their applicable conditions.This paper only introduces models about transverse momentum distribution and shower expansion as well as trigonometry.
