铅合金理化性能测试的探讨(二)──关于力学性能的检测误差

Discussions on testing results of physico-chemical performance of lead alloys Part 2. On the testing error of mechanical performance of lead alloys

本文探讨了以下五个因素对铅合金检测结果的影响：（1）铅合金中的微量杂质；（2）铅合金配制工艺和化学成份的分布；（3）取样点和检测点；（4）检测方式和方法；（5）时效过程。作者认为，应尽可能地将检测条件统一起来，避免系统误差的影响。否则，检测结果将失去重现性和可比性。作者还指出了检测条件和最佳条件。

Effects were examined of the following five factors on test results of lead alloys. These are: trace impurities in lead alloys; (2) alloying procedure and distribution of chemical components; (3) sampling spots and testing points; (4) testing procedure and methods; (5) ageing process.To avoid the influence of systemic error the testing conditions should be unified whenever possible.
