The biomarkers such as the n-Alkanes, the isoprenoids, the terpane, and cholestane were detected through GC-MS analysis. Based on the study of the biomarkers, the biological evolution during Permian and Triassic can be divided as three stages, namely, the mixing source stage of low biota such as thallose and advanced plant in late Permian (below bed 63), the stage of low biota such as thallose in the boundary transitional layer (bed 63-69) and the mixing source stage of advanced plant and low biota such as thallose in early Triassic (above bed 69). What's more, the second stage near the boundary transitional layer can be subdivided into 4 stages. The stages of biota evolution is close related with sedimentary environment changing and the boundary transitional layer.

The wave is the core problem of low Fr. current .In order to make diffluent piers with low ridge to be popularized and applied, the surface wave of low Fr. current is chosen as the research object .We measure the surface wave elements and the velocity distribution of various diffluent piers scheme by the experiment of physical model. We also analyze the average wave height, the the average value of the square of wave , unit width of the waves energy , the probability density distribution of wave height ,and the power chart character, so as to reveal the weakening wave mechanism of the diffluent piers .
