*3.4. Adjustment of Model*

After the final model of molecular structure is obtained, the molecular formulas and element contents of the three models of HLH under different modification conditions are calculated. By comparing the results of Tables 13 and 14, it can be seen that the element contents of the three models are very close to the experimental values, and there is no significant difference, which verifies the reliability of the model.


**Table 13.** Element content measured by experiments of HLH before and after modification.

**Table 14.** Molecular formula and element content of the model of HLH before and after modification.
