| Abstract: | An adjustable parameter modelling method of differential equations with varying coefficients is proposed in combination with a nonuniform control pearmeter in this peper.With this method,it is easy to manipulate the differential equations with varying coefficients in maths caused by the non-uniformity and non-linearity in physiscs and geometry4 Using this model,the satisfaCtory valuable results with only a few element units can be obtained. |
