摘　　要：首先指出了基于传统的假设检验理论的三步法在评价模糊度整数解正确性时存在的理论缺陷 ,然后介绍了模糊度归整域的概念和可容许整数估计的定义 ,并在可容许整数估计原定义的基础上给出了更为严密的新定义。最后 ,基于这个可容许整数估计的新定义 ,讨论了模糊度成功率的概念及其计算公式。从理论上讲 ,只有模糊度的成功率才是评价模糊度整数解正确性的严密尺度。In this paper, firstly the theoretic pitfal, which is caused through evaluation the rightness of integer ambiguity solution based on the three step approach of the traditional hypothesis test theory, is pointed out; then the concept of the pull in region for ambiguity and the definition of the admissible integer estimation are introduced, and on the basis of the original definition for the admissible integer estimation a new severer definition is given; finally based on this new definition of the admissible integer estimation, the concept of ambiguity success rate is discussed and the corresponding formulas are deduced. Theoretically speaking, only ambiguity success rate is a severe approach to evaluate the rightness of ambiguity integer solution.
