The core of the debate between Latour and Bloor on the Strong Program was the confrontation of Bloor\'s symmetry principle of Strong Program and Latour\'s second symmetry principle. The essential disagreement between their theories was whether to insist the subject-object schema, or to discard it. Each of them adopted his own criterion of metaphysics and the different criteria resulted in two different kinds of relativisms. Both sides fell into the same philosophical dilemma. The debate between the post-SSK represented by Latour and the SSK represented by Collins and Yearley intensively revealed their disagreement in interior social construction, manifested by the opposition between social realism and ontology of nature-society mixture, between the normative method and descriptive method, between signified view of science and practical view of science, respectively.It is necessary to trace and clarify the core concepts of Latour\'s "Actor-Network Theory" such as "actor","network","agent", etc.

The results of 3-D numerical modeling of the transversely isotropic media with horizontal symmetry axis and the orthorhombic symmetry media showed that quasi P wave,quasi-SV wave and quasi-SH wave occurred during elastic wave propagation in 3-D anisotropic media. Meanwhile, the special phenomena such as the S wave splitting, the blind zone of S wave splitting and quasi-SV wave-front triplication were clearly observed. In addition, the elastic wave-fronts are spatially changed, and the coupled relations among the quasi-P wave,quasi-SV wave and quasiSH wave in 3-D anisotropic media are very complex.
