title: Comment on "Role of liquid compressional viscosity in the dynamics of a sonoluminescing bubble".
abstract: Moshaii and Bonabi found a new viscous term to the traditional bubble boundary equation and declared it greatly affects the motion of the sonoluminescing bubble. However, the simple analysis and recomputation show it is incorrect.
