In this paper,we study the singular perturbation of boundary value problem of systemsfor quasilinear ordinary differential equations:x′=f(t,x,y,ε),εy″=g(t,x,y,ε)y′+h(t,x,y,ε),x(0,ε)=A(ε),y(0,ε)=Bε,y(1,ε)=C(ε)where xf.y,h,A,B and C belong to R″and a is a d

中国近现代哲学史的整体研究,上世纪80年代曾出现过蓬勃的势头,李泽厚、冯契、冯友兰诸大家先后推出了专门著作。随着学术风气的转移,如何以新的视角来考察近代以来中国哲学的变革与创新,并作新的理论综合,是许多哲学史研究者共同关心的问题。
In the view of Reissner’s and Kirchhoff’s theories,respectively,we formulate theisotropicalized governing equations for the anisotropic plates,and give the pr
