提出一种可以根据一个测点的加载－卸载曲线计算整个压入深度内的硬度变化的新方法，适用于研究整体材料表层的硬度分布。计算与实验吻合良好。
A new method that can calculate the hardness change of the whole depth according to the loading-unloading curve of a measuring point is proposed. It is suitable for studying the hardness distribution of the whole material surface. The calculation is in good agreement with the experiment.
