量规是工业生产中常用的测量工具，用于测量物体的尺寸、形状和位置等参数。在生产过程中，量规的重复性和再现性是非常重要的，因为它们直接影响到产品的质量和生产效率。因此，量规重复性和再现性研究是必要的，以确保量规的准确性和可靠性。

ISO/TR 12888:2011提供了一些选定的图例，用于说明如何进行量规重复性和再现性研究。这些图例包括了不同类型的量规，如千分尺、卡尺、高度规等，以及不同的测量方法，如单次测量、多次测量、多个操作员测量等。这些图例还包括了数据分析和结果解释的示例，以帮助用户理解如何评估量规的重复性和再现性。

ISO/TR 12888:2011还提供了一些建议，以帮助用户进行量规重复性和再现性研究。这些建议包括：

1.选择适当的量规和测量方法，以确保研究的准确性和可靠性。

2.确定适当的样本大小和测量次数，以确保结果的可靠性和统计显著性。

3.使用适当的统计方法进行数据分析，以确定量规的重复性和再现性。

4.解释结果并提出改进建议，以改善量规的准确性和可靠性。

总之，ISO/TR 12888:2011提供了一些有用的图例和建议，以帮助用户进行量规重复性和再现性研究。这些图例和建议可以帮助用户评估量规的准确性和可靠性，并提出改进建议，以提高产品质量和生产效率。
