摘要
该文通过分析、探讨,确立了现阶段常用标尺选择的定量依据;同时,建议以A标尺作为未知硬度材料的首选标尺。在此基础上,实践教学过程中应该将重点侧重于标尺选择、测试样品的准备等方面,关注于培养同学们分析问题的基本方法。
In this article, analysis and discussion are conducted to establish a quantitative basis for gauge selections and the scale A is recommended as the first choice of gauges for materials with unknown hardness. On this basis practice teaching process should focus on the proper selection of gauges and preparation of testing samples, and develop the fundamental analytical capability of the students.
