  • A linear boundary value problem for generalized biregular function vectors
    廣義雙正則函數(shù)向量的線性邊值問(wèn)題
  • The linear boundary element method of calculating the problems of 2d electrostatic field
    用線性邊界元分析二維靜電場(chǎng)問(wèn)題
  • In this part , the first work is pretreatment of a numerical model , including creating calculating grids automatically , improvement of the linear boundary technique and so on . the second work is to estimate the siltation of a basin or channel by liu ' s equation . the third work is to build an edbms ( engineering data base management system ) for the result of mathematical model
    其中主要的工作是:其中主要的工作一是數(shù)學(xué)模型的前處理,計(jì)算網(wǎng)格自動(dòng)生成,線邊界法的優(yōu)化;二是應(yīng)用劉家駒公式在長(zhǎng)江口深水航道治理工程地理信息系統(tǒng)的支持下實(shí)現(xiàn)港池、航槽開(kāi)挖的實(shí)時(shí)回淤估算;三是將計(jì)算成果形成gis管理和支持下的工程數(shù)據(jù)庫(kù)系統(tǒng)( engineeringdatabasemanagementsystem ) ,同時(shí)嘗試解決時(shí)間序列數(shù)據(jù)如地形沖淤變化,潮位、流速過(guò)程的分析、查詢和顯示問(wèn)題,并實(shí)現(xiàn)實(shí)時(shí)、互動(dòng)的動(dòng)態(tài)演示及三維可視化。
  • The condition under which the dirac operator is self - adjoint is discussed under the general linear boundary condition between the interval of two points . for the expansion theorem of non - self - adjoint dirac operator , it is unable to use the method of integral equation . but under the linear boundary condition and unlocal boundary condition , the eigenvalue expansion problems of non - self - adjoint operator can still be discussed by using the residue method
    對(duì)于非自伴dirac算子的特征展開(kāi)定理已無(wú)法應(yīng)用積分方程的方法,本文仍用留數(shù)方法對(duì)一個(gè)兩點(diǎn)非自伴邊界條件和一個(gè)非局部邊界條件下產(chǎn)生的非自伴算子的特征展開(kāi)問(wèn)題進(jìn)行了討論,分別得到了它們的特征展開(kāi)定理。
  • Abstract : this paper discusses high order numerical model of non - linear boundary equation . by using integral technique , the boundary condition problem is turned into a form initial condition problem . we construct 4 order numerical formula . the convergence theory is given and proved . the examples show that our method has fast convergence speed and less numerical time
    文摘:討論非線性邊值問(wèn)題的一種高精度計(jì)算模型.利用積分值將邊值問(wèn)題轉(zhuǎn)化為形式初值問(wèn)題,構(gòu)造了一類四階精度的計(jì)算格式,證明了收斂性.通過(guò)算例表明該方法收斂速度高,計(jì)算量小
  • Abstract : the mechanical analysis for arch bridge with flat hinge joints is a mechanical problem with non - linear boundary . mechanical analysis of methods at present is not clear , which can not calculate the arch bridge with changeable section and section with complicate shape . in this paper , the new method used to get the section resistance coefficient k is presented , the iterative procedure is established to calculate the internal forces of arch bridge with flat hinge joints , and the computational example is given . the method can apply to the arch bridge with any numbers of flat hinge joints and any shape section
