Simulation investigates the distribution of gases in channel, leading to pressure drop and material distribution variation.
Although there are same feature in flowing state for Hilbert channel and serpentine channel, the composite Hilbert channel has lower pressure drop that can spread materials through channels easier and can distribute more uniformly.

Material model In the LSP process, strain-rates exceed more than 106 S-1 within the target material.
In the present literature, Hugoniot’s elastic limit (HEL) and Johnson-Cook model are the two basic approaches to modelling of materials subjected to LSP [9].
The peak pressure is calculated by the following formula (2) [12]: (2) Where is the incident laser power density; is the peak pressure; is the reduced shock impedance between the target and the confining materials; is the efficiency of the plasma-material interaction ().

Introduction With the development of science and technology and the improvement of living quality, the social demand of sound absorption material increases rapidly, such as concert hall, cinema, recording studio, audiometric room, KTV, multi-media studio, meeting room, auditorium, multi-media classroom and so on, where excellent sound absorption materials should be used to produce appropriate loudness, higher definition, enough fullness, nicer expansion and space feeling through acoustic quality design , and to make it no acoustic echo and flutter and other acoustic defects.
Some scholars have done researches on the acoustical performance of woodiness materials.
