简要介绍了非线性科学中的分形维方法和信息熵方法及其用于房颤信息的处理和分析，计算了未房颤时P波的及房颤时f波的格子维和信息熵，特别是，比较了未房颤时和发生房颤时的相关计算结果的显著差别，从而很容易判断是否发生了房颤。

The fractal-dimension theory and the Shannom entropy theory of nonlinear science are briefly described, and the methods to apply them to analyze AF's information are developed. The grid-dimension values and the Shannom entropy values of P-wave and those of f-wave are computed. The comparison of the remarkable difference between values of these two kinds of waves is given so as to easily determine whether AF happens or not.
