【Abstract】 The purpose of this paper is to construct new operation of variable precision approximation operator and grade approximation operator,and to explore its algorithm of calculation.We propose in the paper the difference operation of variable precision lower approximation operator and the grade upper approximation operator as well as the macroscopic algorithm and the microscopic algorithm,and make analysis and comparison on these algorithms.A medical example is utilised to analyse and explain the macroscopic algorithm and microscopic algorithm.更多还原
