Abstract: 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 [1] is a kind of specific form of the present recursive algorithms given here.
