用D-语言方法建立了微积分理论的新体系.D-语言方法实质上是拓扑学中刻画收敛的滤子基方法, 该方法将序列收敛与集列收敛,函数极限与集值函数极限相结合,具有简明化、图解化、算法化、易于掌握等优 点.<正>In this paper, by using D-language, new interpretation of e-S calculus is given. The nature of D-language method to describe convergence is given. It is the filter base method in topology. The D-language method combines the convergence of sequence with the convergence of set sequence, the limit of function with the limit of set value function has the advantages of simplification, graphic, algorithm and easily-mastered.
