本文讨论了现有的三种分数阶微积分基本定义(R-L(Riemann-Liouville)定义、G-L(Grumwald-Letnkov)定义和Caputo定义)对阶数的适用范围
以及三者 之间的关系;强调指出分数阶导数与整数阶导数之间的区别.通过对分数阶微积分一个统一公式的讨论
以及给出分数阶微积分一个简单的物理解释
加深对分数阶微积分本质的认识;提出定域长分数阶微积分定义
给出它的直接数值算法
预期它可能在实践中得到应用.
In this paper the order-range applied by fractional calculus R-L definition
G-L definition and Caputo definition along with the connections between above three definitions are discussed.The differences of fractional-order derivatives and integer-order derivatives are pointed out.An uniform formula of fractional-order integrals and derivatives along with a physical interpretation of fractional calculus are given.The definition of fractional calculus with constant extent of integral and its direct numerical value arithmetic are put forward
and its application is anticipated.
