摘要
本文基于不可微优化理论,建立了形位误差统一判别准则。该准则的必要条件同样也适用于计算机判别。而后,利用极大熵函数,构造了形位误差评定的有效统一算法。该算法简单,易于使用,评定精度高。
Based on the nondifferentiable optimization theory,the unified evaluation criteria and algorithm for the form-position errors are proposed.The essential conditions of the evaluation can be judged by a computer.The effective unified algorithm for the evaluation of form-position errors are given according to maximum entropy function.The algorithm are more simple,easy to use,with higher evaluation accuracy and faster calculation velocity.
