In this talk,we will discuss the KdV limit of the Euler-Poisson system in the long wavelength limit.We will discuss this limit both formally and mathematically
We present in this talk the real analyticity of all the streamlines,including the free surface,of a steady flow of water over a flat bed,with a H(a)lder continu
In this talk,I will introduce a recent result on lifespan of smooth axi-symmetric solutions to 2-D compressible non-isentropic Euler system.Here small smooth in
In this talk we first give a survey of the Strauss conjecture,and then show the blow up result for the initial boundary value problem of critical semilinear wav
Using the method developed by Camillo De Lellis and Laszlo Szekelyhidi for the incompressible Euler system we prove that in the case of compressible isentropic
光催化氧化技术是一种利用光催化反应过程中形成的强氧化性自由基与大量有机分子反应以生成更容易生物降解或者毒性较低的分子的方法。该方法以其高效、环保和降解彻底的特性
The quasi-neutral limit of the full Navier-Stokes-Fourier-Poisson system for the plasmas and semiconductors in the multi-dimensional torus is considered in the
超级电容器是一种新型的储能器件,具有许多储能器件无法比拟的优点。比传统电容器具有更高的能量密度;相比蓄电池,超级电容器具有更高的功率密度并且循环使用率更长久。电极材料作为器件中最为重要的组成部分,其电容值的大小会直接影响到整体器件的电化学性能。电极材料的电容值越高,器件的能量密度就越高。本论文采用水热沉积法制备出具有良好电化学性能的α-Ni(OH)_2电极材料,制备过程中通过引入阴阳离子,对α-N
