Putaohua reservoir fault have a dense like banding characteristics, and more boundary fault of dense banding are oil source fault activities for the accumulation period;

Conclusions Compared with the conventional chromosome banding technique, FISH has characteristics of high sensitivity and accuracy, and provides a good assist method for diagnosis.

Under the loading conditions of uniaxial and slightly biaxial tension, the characteristics of material bifurcations (plane shear banding and surface wrinkling) are demonstrated.
