superposition theorem
1.A method is set forth to calculate the hydrodynamic pressure influence matrix of elastic dam using series development and linear superposition theorem in this paper.
2.Abstract: A method is set forth to calculate the hydrodynamic pressure influence matrix of elastic dam using series development and linear superposition theorem in this paper.
3.A detailed demonstration about the provement,the relation with the linear system,the homogeneity property and the additivity property of the superposition theorem is also given。
4.In electrotechnics it is found that in the experiment of superposition theorem, there exsists some difference between the experiment resut and its theoretical caculating value, in this paper, the cause for this difference is analysed and a solution to this problem is offered.
5.The technique proposed builds the sound field separation formula in wave number domain according to the superposition of particle velocity theorem and Euler equation in wave number domain, then the sound pressure caused by sources on one side of holographic plane can be obtained as expected by talcing inverse two-dimensional Fourier transform of this formula.
