摘要
The paper illustrates the views including the following from the comparison between line sound source and point sound source:point sound source with the same sound power can transmit farer than finite length line sound source;constant amplitude curved surface of finite length line sound source is the flexible olive spherical surface between cylindrical surface and spherical surface.
The paper illustrates the views including the fonowing from the comparison between line sound source and point sound source：point sound source with the same sound power can transmit rarer than finite length line sound source;constant amplitude curved surface of finite length line sound source is the flexible olive spherical surface between cylindrical surface and spherical surface.
