The quadratic nonlinear term and the cubic nonlinear term that coexist in equation ( 1 ), thus causes difficulty in studying this sort of system through the analytical method and correspondingly makes the solution of analytical expression of homoclinic orbit or heteroclinic orbit in hamilton system extremely difficult
二次非線性項和三次非線性項共同存在於方程（ 1 ）中，使得用解析方法研究這類系統的難度增大，對應hamilton系統中的同宿軌道或異宿軌道的解析表達式的求解相當困難。 -
Abstract : based on the concept of space migration length of photo - activation species, the analytical expression of the total number n of photo - activation species that can reach a segment on the substrate in the cubic deposition reaction space is derived. the simulation of the relationship of deposition rate and position of substrate is also completed. the simulation result agrees with the experiment data well
