%X By using laser Moire Deflectometry and piezoresistance pressure sensors the basic structure of initial shock wave caused by exhausted flow field is studied. The study shows that the initial shock wave exists in front of the exhaust flow and in its initial stage it has a concave center. A new theory for the developing structure of initial shock wave front is also put forward in this paper.
