Analytical Periodic Wave and Soliton Solutions of the Generalized Nonautonomous Nonlinear Schrdinger Equation in Harmonic and Optical Lattice Potentials

We construct analytical periodic wave and soliton solutions to the generalized nonautonomous nonlinear Schrdinger equation with time-and space-dependent distributed coefficients in harmonic and optical lattice potentials.We utilize the similarity transformation technique to obtain these solutions.Constraints for the dispersion coefficient,the nonlinearity,and the gain(loss) coefficient are presented at the same time.Various shapes of periodic wave and soliton solutions are studied analytically and physically.Stability analysis of the solutions is discussed numerically.     

电泳辅助制备伪1-3陶瓷/聚合物压电复合材料

1-3压电复合材料的压电、介电及铁电性能要远远优于0-3压电复合材料.在制备传统的0-3复合材料过程中引入电泳技术,使得压电颗粒在聚合物基体中取向排列,制备得到伪1-3复合材料.实验结果表明:在制备PZT/环氧树脂0-3复合压电材料固化过程中,采用500 V/mm,4 kHz的电场对其进行电泳辅助取向,可使得颗粒呈现珍珠串状排列,得到伪1-3复合材料;其压电、介电、铁电性能均比原来的0-3复合材料有显著的提高.电泳辅助制备技术用于制备伪1-3复合压电材料具有操作简单、成本低廉、压电、介电、铁电性能显著提高等优点,在智能传感领域具有很好的实际应用前景.
