里氏硬度值与布氏硬度值、洛氏硬度值的关系

Relationship of LeeB's Hardness Value to Brinell and Rockwell Hardness Value

利用回归法推测里氏硬度值与洛氏、布氏硬度值的关系，并验证里氏硬度计在生产和现场检验中，可以利用里氏硬度计代替其他硬度计测定诸如洛氏、布氏硬度值，数据精度较可靠。

The relationship of Leeb's hardness value to Brined and Rockwell hardness value is colculated by regression method, it also proves the data accuracy is basically reliable when using of LeeB's hardness meter to replace of Brined and Rockwell hardness meter to determine Brined or Rockwell hardness value in prduction.
