摘要
对日本真空理工株式会社制造的DL-1500热膨胀仪的测量结果的系统偏差进行了研究,使用该会社提供的铂、三氧化二铝标准样品在50～1200℃进行测试,通过对测试数据的比较分析,发现正确选用计算公式和参照标样可有效地降低测量结果的系统偏差。
The system deviation of the measurement results by using a DL-1500 thermal expansion instrument made by Japanese Vacuum Technique Corporation was analysed. Through the measurement of Pt and Al_2O_3 standard samples provided by this corporation in 50～1 200℃ and subsequent data analyses, it was found that the system deviation of the measurement results can be effectively decreased by using proper calculation formula and reference samples.
