| Abstract: | Six physical universals and two general relations in the problem of locally forced precursor soliton generation are found
thcoretically in terms of the AfKdV equation derived by authors. These six universals and two general relations are examined
by experiment and numerical calculation of two-layer flow based on the canonical character of the coefficients of tlie fKdV
equations. From comparisons among the theoretical, numerical and experimental results, it is shown that they are in good agreement.
There is not any free parameter in this theory, so the theory of the present paper can be used to predict thc wave properties
of locally forced precursor soliton generation.
