摘要：
We consider the one-dimensional nonlinear Klein-Gordon equation with a double power focusing-defocusing nonlinearity partial derivative(2)(t)u - partial derivative(2)(x)u + u - |u|(p-1) u + |u|(q-1) u = 0, on [0,infinity) x R, where 1 < q< p 0.77) for the equation generated to assess the relationships demonstrated that differential pressure fluctuations could be used as a promising tool to determine the hydrodynamic parameters' characteristics in the flotation columns.
