First the systemdeviation was corrected, then the uncertainty of measuring result was analysed by using the definition of the uncertainty.
首先对其系统偏差进行了修正，然后据不确定度定义对其测量结果进行了不确定度的分析。

The Systemdeviation of the measurement results by using a DL-1500 thermal expansion instrument made by Japanese Vacuum Technique Corporation was analysed in this work.
对日本真空理工株式会社制造的DL - 1 5 0 0热膨胀仪的测量结果的系统偏差进行了研究。
