A Computational Model Based on the Abacus - Abacus Machine
一种基于算盘的 —算盘机

A computational model based on the abacus. Abacus Machine, is introduced in this paper. After the "Abacus Machine" and "Abacus Machine Computable" are defined, it is shown that the computing power of Abacus Machine is identical to that of Recursive Functions.
