The recrystallization nucleation by bulge of high Angleboundary is promoted by a large mount of particle present in the vicinity of grain boundary.
实验结果还表明晶界附近存在较多的粒子促进已存大角度晶界凸出的再结晶形核。

They also can expand the buffet boundary and decrease the buffet intensity. As a result, the largeangle-of-attack flying quality can be significantly improved by utilization of maneuvering flaps.
