| 摘 要： | 从纳米压入测量的基本原理出发介绍了压头面积函数及其校对方法，并对熔融石英进行了两次纳米压入测量，校对了两次压头面积函数，两次测量及校对的时间间隔为1a（年）。结果表明，两次校对后的压头面积函数差别较大。若第二次测量的熔融石英数据仍采用第一次校对的面积函数进行计算，将使杨氏模量和硬度测量结果产生很大误差，阐明了压头面积函数校对在纳米压入测试中的重要作用。 |

| Abstract: | The tip area function and its calibration method were introduced based on the basic principles of nanoindentation. A nanoindentation test on a fused silica and the calibration of the tip area function were pel-formed in sequence, The test and calibration were repeated one year later. It was found that two tip area functions got from calibrations varied significantly. Calculating the data collected from the fused silica one year later by using the tip area function got from the first calibration leaded to big differences between results of Young＇s modulus and that of hardness. The calibration of tip area function played an important role in nanoindentation test. |
| Keywords: | Nanoindentation Tip area function Young＇s modulus Hardness |
