Influence factors of sound absorption properties of closed-cell aluminum foam;
闭孔泡沫铝吸声性能的影响因素
The uniaxial tensile properties of two aluminum foams(open-cell and closed-cell foams)with a variety of densities were studied and compressive tests were carried out.
研究了开孔与闭孔两种胞孔结构的泡沫铝在不同相对密度下的准静态拉伸力学性能,并与单向压缩性能进行了对比。
Many pore sealing methods have been developed but they are all have shortcomings.
人们采用了许多封闭孔隙的方法,但都存在不足。
