Abstract：The wave equations of Biot theory and modified Biot theory were derived, and the dimension and accurate meaning of each parameter in the equations were clearly indicated. Based on the modified Biot theory, three different forms of wave equations were gained as well. Then, by comparing those two theories, the expressions of the elastic coefficients in Biot theory were obtained, and the stresses and their correspondences were analyzed. Finally, emphasis was given to the discussion on the positive direction and meaning of pore-fluid pressure, as well as on the definition of some parameters in the fundamental equations, which may be easily confused and misunderstood. The above analysis and discussion promote better understanding and application of Biot theory and modified Biot theory.
