General solution after extension to other cases. Seek the same sex through special cases and draw a conclusion. It is characterized by its combination with practice and strong operability. But the logic is not rigorous enough and the theoretical support is insufficient.

Empirical research is rational, and it draws conclusions through repeated experiments and arguments. It is characterized by rigorous logic. However, it is likely to be divorced from reality and less operable than case analysis.

Generally speaking, it is necessary to combine the two methods to analyze the problem, so as to get theoretical support through the theoretical framework and have strong operability.
