| 摘 要： | 应用模糊和随机理论,克服了在不确定度绝对值综合法ey1和方和根综合法ey2中存在的缺点:首先给出了ey1和ey2中的近似分界;然后对ey1的偏大估计和ey2的偏小估计进行了修正.经过改进后的珓ey1和珓ey2不仅简单实用、约束条件少、适用面广,而且其综合准确度也能满足一般工程测量上的需要.

| Abstract: | In this paper, the theories of fuzziness and randomness are used to solve the problems in the absolute value sythetical method for ey1 and the square root sythetical method for ey2. First, the approximate boundary between eyj and ey2 is proposed. Second, the overestimation of eyt and underestimation of ey2 are modified. The modified ey1 and ey2 have the advantages of simplicity, practicality, less constrains, and vast applications. And their accuracy can also meet the requirements in general engineering measurements. |
