PADE′逼近在FEL数值模拟中的应用

PADE'APPROACH IN THE FEL'S NUMERICAL SIMULATION

应用 PADE′逼近方法构造出高阶格式,对一类简单方程组,该方法可导出一种快速递推算法,它能满足这类简单方程自身存在的守恒要求。

Higher-order accuracy schemes are established following PADE' approach.Based on the schemes,fast recursive algorithms for the simple equations.Can be obtained and satisfy the corresponding conservation law.The fast recursive algorithm in the reference is a kind of specific form of the present recursive algorithms given here.
