针对表面纹理的参数评定问题，提出了表面纹理可以从纹理图案和纹理粗糙度两方面入手加以评定的观点．重点探讨了运用三维粗糙度的几项特征参数定量地评定表面纹理问题．介绍了特征参数的计算原理、测量方法，并且对所测的数据进行了统计分析，拟定了部分纹理的参数标准，验证了采用特征参数评定表面纹理的可行性 In view of the problem of parameter evaluation of surface texture, the viewpoint that surface texture can be evaluated from two aspects of texture pattern and texture roughness is put forward. Focusing on the use of three-dimensional roughness of several characteristic parameters quantitative assessment of surface texture problems. The calculation principle and measurement method of the characteristic parameters are introduced. And the statistical analysis of the measured data is made. The parameter standard of the partial texture is established. The feasibility of using the characteristic parameters to evaluate the surface texture is verified
