Opposition to the flow of sound through a surface,acoustic resistance is the real component of acoustic impedance and acoustic reactance is the imaginary component. 声音在通过一个表面时受到的阻力，声阻是声阻抗的实部，声抗是声阻抗的虚部。
It was experimentally proved for the first time that the maximum acoustic power output can be transferred to the load when the acoustic resistance of RC load equals to its acoustic capacitance impedance. 首次通过实验验证了当声阻与容抗相等时,热声发动机向阻容负载传递的声功率最大。
With the trouble-free motor and chemically resistant enclosure the Primus 208 moves straight forward on its way. 产品介绍： The rugged standard version Our Primus 208 pump is exemplary in reliability and reduction of costs.
