《GB/T 18778.2-2003产品几何量技术规范（GPS） 表面结构 轮廓法 具有复合加工特征的表面 第2部分: 用线性化的支承率曲线表征高度特性》由TC240（全国产品几何技术规范标准化技术委员会）归口，主管部门为国家标准化管理委员会。
本标准规定了根据支承率曲线线性特征确定参数的评定方法。该曲线描述了随着粗糙度轮廓的深度增加而引起表面材料部分的增加。
Scope
This part of GB/T 18778 specifies the evaluation method for determining parameters based on the linear characteristics of the support rate curve (also known as the Abbott curve). The curve describes the increase in surface material fraction as the depth of the roughness profile increases. This section is suitable for evaluating the working performance of surfaces subjected to high mechanical stress.
