To achieve this, the specimen is immersed in a polymer solution and placed in a vacuum chamber.
为了达到这一目的，标本将被浸泡进真空压力室里的聚合体溶液中。

The specimen deformation and the crack morphology were studied. After comparing with the fracture of flame chamber of aerojet, the most suitable size and shape of specimen notch has been determined.
The system has an interface (116) in a wall of the chamber for removably accommodating the first holder (112) or a second holder (118) with a second specimen (120) mounted thereon.
