- Study on the Characteristics of Macromolecular Chains of Cellulose in Dilute Solutions摘要:The characteristics of macromolecular chains of cellulose in dilute solutions are discussed. Viscometry was used for the measurement of the intrinsic viscosity [η] of four cellulose samples, which were respectively diss…查看全部>>
- Existence of Positive Solutions of Nonlinear NeutralEquations with Positive and Negative Coefficients摘要:A class of nonlinear neutral equations with positive and negative coefficients is considered. Seveal conditions for existence of eventually positive solutions are obtained,and they extend and improve some of the c…查看全部>>
- Existence of Nontrivial Solutions of A Nonlinear Volterra Integral Equation摘要:Some new results on the existence of nonnegative nontrivial solutions of the nonlinear Volterra integral equation,u(x)= k(x,s)g(u(s))ds,(x≥0),are given and their applications are shown.
- The 2D Fundamental Solutions in BEM Applied for Piezoelectric Materials摘要:It is expected to solve the piezoelectric problems by using numerical method,e.g.,the boundary element method,since analytical solutions can hardly be obtained due to the deformation,electric field coupling effects of t…查看全部>>
