experiment and change of metal flow line, metallographic structure and micro-hardness in deformation zone, this paper researched process, characteristic and mechanism of fine-blanking.───通过实验和变形区流线变化、金相组织和显微硬度的变化，对精冲成形的过程、特点、精冲成形机理进行了研究。
Bottom simulating reflector(BSR) and amplitude blanking zone with high velocity above BSR are the indicators of hydrate.───目前识别水合物的主要依据是BSR和其上具有高速特征的空白带。
Bottom simulating reflector (BSR) and amplitude blanking zone with high velocity above BSR are the indicators of hydrate.
In seismic data, it is often associated with bottom simulating reflectors ( BSR ) and blanking zone.
Therefore the research on the cause of BSR and blanking zone is very necessary in gas hydrate research.
The research on blanking zone shows that the variation hydrate saturation is altering with porosity in the blanking zone.
Bottomreflector ( BSR ) and amplitude blanking zone with high velocity above BSR are the indicators of hydrate.
The thesis testifies that the cause of BSR and blanking zone can be explained with different models.
Geophysical methods in exploiting gas hydrates include bottom simulating reflector, blanking zone, reversal of reflection polarity, VSP, AVO and VAMP'S structures, well logging and so on.
