研究了一个大气物理中洛伦兹系统的求解问题.首先利用广义变分原理构造一组变分迭代,其次决定系统的初始近似,最后通过变分迭代方法得到了对应模型的各次近似解.广义变分迭代方法是一个解析方法,得到的解还能够继续进行解析运算.
A solving problem for the Lorenz system in atmospheric physics is considered.First,a set of variational iterations is constructed by using the generalized variation principle.Then,the initial approximate solution is determined.Finally,using the variational iteration,each approximate solution for corresponding model is found.The generalized variational iteration method is an analytic method,and the obtained solution can be analytically operated further.
