在实际生产中，我们常常迁到这种情况，某种材料给定某种硬度值（或布氏、或洛氏，或维氏），而所需研究的却是另一种硬度值，这样就必须换算。常用的换算方法是查表法或经验公式法，而查表法的缺点是有些数据在表中没有。如：在GB1172－74里，HRC52以上的对应布氏值未给出，且
In actual production, we often move to this situation, a material given a certain hardness value (or Brinell, or Rockwell, or Vickers), and the need to study is another hardness value, so It must be converted. Commonly used conversion method is the table look-up method or empirical formula method, and the shortcomings of the look-up table is that some of the data in the table does not. For example, in GB1172-74, the corresponding Brinell value above HRC52 is not given, and
