1.The data of NT62-2 seismic line of western Nankai Trough are reprocessed, and the character of the distribution of Bottom simulating reflector (BSR) is emphasized.
2.Bottom simulating reflector(BSR),polarity reversion,amplitude blanking zone and velocity anomaly express on the seismic profile DMS01-5,which indicate occurrence of gas hydrate related to mud volcanoes.
3.The bottom simulating reflector (BSR) is the most important indicator for identifying gas hydrates, but it is not a feasible indicator since there is no strict corresponding relationship between gas hydrate and the BSR.
4.The tank has two absorption surfaces: the bottom one is heated by a boosting reflector, and the upper one is covered with a 5cm-thick transparent honeycomb plate and a 2mm thick acryl glass.
