  • 表示函數(shù)
  • 指標函數(shù)
  • 指示函數(shù)

Examples

  • Numerical tests shows that indicator function method is a simple and fast method , by which better reconstruction can be gained for no superior knowl - edge of the physical properties about media
    數(shù)值實驗表明，指示函數(shù)方法簡單快速而準確，能在不對介質(zhì)的物理性質(zhì)有先驗的假設(shè)基礎(chǔ)上，給出較好的重構(gòu)效果。
  • From mathematical models for inverse scattering in two dimensional inho - mogenous media including variable impedance , all kinds of probable mixed variable impedance boundaries and cracks , from interior and exterior trans - mission problems and radiation condition , ill - posed integral equation and indicator function method are formulated for the diverse of boundary iden - tification . it is shown that the kernel of the integral equation characters the boundary of scatterer , which is determined by solving it by virtual of regularity method , meanwhile , some numerical tests are given . 3
    在二維非均勻介質(zhì)逆散射邊界識別的數(shù)學模型(包括一般的非均勻介質(zhì)，正交各向異性介質(zhì)，變阻抗介質(zhì)，各種可能的混合變阻抗邊界問題)下，由內(nèi)透射問題和外透射問題以及輻射條件，推導了上述介質(zhì)的邊界識別的積分方程和指示函數(shù)方法，由于積分方程的核充分表征了散射物的邊界，由此說明只要利用正則化方法求解該積分方程，就可以確定散射物的邊界。
  • First , in virtual of identification of flaws is a typical of in - verse problems , proceeding from time - harmonic electromagnetic maxwell ' s equa - tion and helmholtz equation , the uniqueness and existence of direct scattering problems including the numerical algorithms of diverse of boundary conditions is given . second , the uniqueness and existence of inverse scattering problems and the theory of ill - posed integral equation are briefly looked back upon . finally , indicator function method for boundary identification is set up under all kinds of boundary conditions for inverse scattering of homogenous and inhomogenous objects , meanwhile , the proof of possibility for near - field measurements and nu - merical simulation are given
    由于缺陷的識別是一類典型的反問題，因而首先從時諧電磁maxwell方程和helmholz方程出發(fā)，具體地闡述了求解正散射問題的有關(guān)方法，包括各種(夾雜)邊界條件下的數(shù)值解法，就解的存在性唯一性給予了肯定的回答；隨后對逆散射問題的理論作了簡短的回顧，包括解的唯一性以及非線性不適定積分方程的處理等；然后對均勻介質(zhì)和非均勻介質(zhì)的逆散射問題建立了在各種邊界條件下的邊界識別的指示函數(shù)方法，鑒于近場數(shù)據(jù)獲得的重要性，對近場測試時邊界識別的方法給予了相應(yīng)的證明，并且實現(xiàn)了數(shù)值模擬。
  • Conditions of normal mode realization are deduced and optimized model with the multivariate mode indicator function as the target function is built . through solving the maximal eigenvalue problem , the original shaker force vector of appropriation is reached . then the realization approach of the optimal shaker force vector based on single shape principle is proposed and at the same time the automatization of normal mode appropriation is realized

  • From mathematical models for inverse scattering in two dimensional homoge - nous media including dirichlet , neumann , robin , all kinds of probable mixed boundaries and cracks , direct and inverse scattering are discussed , and ill - posed integral equation and indicator function method are formulated for the diverse of boundary identification . it is shown that the kernel of the integral equation characters the boundary of scatterer , which is determined by solv - ing it by virtual of regularity method , meanwhile , some numerical tests are given . 2
    在二維均勻介質(zhì)逆散射各種邊界識別的數(shù)學模型(包括dirichlet , neumann , robin ，各種可能的混合邊界問題，裂紋問題)下，分別考慮了正散射問題和逆散射問題，推導了上述各種邊界識別的不適定積分方程以及指示函數(shù)方法，由于積分方程的核充分表征了散射物的邊界，由此說明只要利用正則化方法求解該積分方程，就可以確定散射物的邊界，并給出了一些數(shù)值實驗。
  • In chapter2 , we establish the model of present value of benefits , which is fitted to two situations - single life situations and multiple life situation : where b ( t ) is a positive function , is force of interest accumulation function , i ( t ) is indicator function and t is the remaining life of the insured
    第2章提出了具有一般形式的變額壽險的給付現(xiàn)值模型，適合于單生命狀態(tài)和多生命狀態(tài)兩種情形：其中b ( t )為正值函數(shù)， y ( t ) = t + ? y ( t )為息力累積函數(shù)， i ( t )為示性函數(shù)。 t為被保險人的余壽。
