leap frog
1.A clase of leap-frog finite difference scheme with higher stability propertiesfor a hyperbolic equation Ut+aUx=0 are proposed in this paper.
2.On the basis of the method of single point subdomain precise integration, the multi-point subdomain precise integration scheme (forward for time;center for space) and leap-frog scheme was obtained from the heat conduction equation of parabolic type.
3.Four kinds of multiple-loop feedback(MF) low-pass filter with current-conveyer are presented. They are : follow the leader feedback (FLF), inverse follow the leader feedback (IFLF), shifeed companion form (SCF) and leap frog (LF) low-pass current-mode filters; each using current-conveyer as active components.
4.The amoy area parties concerned said that, this time drafts to be for the purpose of further promoting the Kuanyinshan international commerce transport business center the social influence, promotes the society from all walks of life to transport business center the understanding which affects in the Xiamen new turn leap frog development, drafts to request to provide Kuanyinshan the international commercial transport business center to start the area whole promotion name, in the start area A1, A2, the A3 land parcel takes a name separately.
