建筑公差 第2部分:预测具有正态分布尺寸的组合体之间配合的统计基础

[中文适用范围]： 描述建筑尺寸变化的基本特征以及随机不相关变量组合的特殊情况。 提出了将尺寸可变性与由于满足功能需求而对接头宽度施加的限制联系起来的需要。 适用于具有遵循高斯分布的可预测变化的所有形式的建筑结构。 [外文原描述]： Describes the fundamental characteristics of dimensional variability in building and of the particular case of combination of random unrelated variables. Sets out the need to relate dimensional variability to the limits imposed on joint widths by the need for satisfactory functioning. Applies to all forms of building construction that have predictable variability which follows a Gaussian distribution.
