摘要:
该文主要研究一维有界区间中具有对数敏感度的趋化模型{?tu = Duxx+(u(lnv)x)x,x ∈(0,1),t > 0,?tv = εvxx+uv-μv,x ∈(0,1),t> 0.根据Cole-Hopf变换将上述带奇性的排斥趋化模型变换为如下的非奇异方程组{pt = pxx+(pq)x,x ∈(0,1),t > 0,qt = εqxx+ε(q2)x+px,x ∈(0,1),t > 0,并在混合边界条件下得到对应的初边值问题解的整体存在性和指数收敛性.

摘要:
Generalized multi‐term time‐fractional diffusion equations have been used to describe important physical phenomena .However ,studies on multi‐term time‐fractional diffusion equations with mixed boundary conditions in high dimensional conditions are still limited .In this paper ,a method of separating variables was effectively imple‐mented to solve a generalized multi‐term time‐fractional diffusion equation (GM TDE ) in a finite domain .In this equation ,the multi‐term time‐fractional derivatives were defined in the Caputo sense ,whose orders belonged to the intervals [0 ,1] ,[1 ,2] ,respectively .The space partial derivatives were classical integer order derivatives whose order were 2 .We discussed and derived the analytical solution of the GMTDE in two dimensions meeting nonhomo‐geneous mixed boundary conditions .The technique reported can be applied to other kinds of fractional differential equations with different boundary conditions .%广义多项时间分数阶扩散方程已被用于描述一些重要的物理现象,目前,有关该类方程在高维情形下满足混合边界条件的研究仍较少。利用分离变量法考虑有界区域上广义二维多项时间分数阶扩散方程,方程中关于时间变量的分数阶导数采用Caputo分数阶导数的定义,其阶分别定义在[0,1],[1,2]。而关于空间变量的偏导数则定义为传统的整数阶导数(二阶),得到了有界区域上广义二维多项时间分数阶扩散方程满足非齐次混合边界条件的解析解。亦可用于求解其他类型的满足不同边界条件的分数阶微分方程的解析解。

摘要:
考虑时谐电磁波对非常薄的无限长圆柱理想导体的散射问题,该散射体在水平截面上抽象为平面上的曲线段(即裂缝)。假设曲线段是光滑的,且其2侧赋予不同的边界条件(混合边界条件),首先证明了散射问题解的唯一性;然后通过位势理论与积分方程方法,将问题转化为等价的奇异积分方程组并证明了解的存在性;最后,通过求解奇异积分方程组给出了混合边界裂缝散射问题的数值模拟。%Consider a scattering problem of time-harmonic electromagnetic plane waves from a thin infinitely long cy-lindrical obstacle. The thin obstacle is a curve segment referred to as crack. Assuming that the crack is smooth,and both sides of the crack have different boundary conditions( mixed boundary conditions),the uniqueness of the solu-tion is firstly given for the scattering problem. Then the scattering problem is transformed into an equivalent system of hypersingular integral equations by the potential theory and the integral equation method,and the existence of the solution is also proved. Finally,numerical simulations of the scattering problem for the mixed boundary crack are presented by solving the system of hypersingular integral equations.

摘要:
对于大跨、高架混凝土梁,太阳辐射引起的温度效应无法忽略,并可能成为结构设计的控制因素.由于现场观测试验从时间、经济性以及可靠度方面均存在不足,依据热传导问题的基本方程,借助有限元分析软件,选择具有一定重现期的气象参数以及合适的材料基本热工参数,可以准确地分析混凝土梁各种温度效应,为结构设计提供参考.

摘要:
基于试验子结构恢复力修正的不完整边界条件混合试验方法及系统,属于结构工程试验技术领域。为解决混合试验中的不完整边界条件问题,本发明提出一种基于试验子结构恢复力修正的不完整边界条件混合试验方法及系统。在常规混合试验划分数值子结构和试验子结构的基础上,本发明对试验子结构建立两套代理模型,两套代理模型和数值子结构模拟方式相同,均在计算机中模拟完成。第一套代理模型设置为完整边界条件;第二套代理模型设置成和试验子结构具有相同的边界条件,属于不完整边界条件。利用两套代理模型对试验子结构的恢复力修正:RE,i+1=RExpSub,i+1+RSurmodel_1,i+1‑RSurmodel_2,i+1,RExpSub,i+1为试验子结构的恢复力,RSurmodel_1,i+1、RSurmodel_2,i+1为两套代理模型的恢复力,RE,i+1为修正后的试验子结构恢复力。本发明主要用于混合试验。
