The load-bearing capability of composite vessels with metallic liner depends on the elastic distortion range of the metallic liner and its stability.

The dual-reflex bandpass, due to the fact that its ports control cone motion over a wider range of frequencies, produces the least distortion and exhibits the best power-handling characteristics.

If the adjacent cell curvature difference, clarify in this range, the surface distortion is very serious, if cut and sew in here is cut off again, then divide membrane block has a great arc here will.
