  1. With the concavity and integrability of sublinear terms near zero, the symmetry results for a class of sublinear elliptic equations are given by making use of the moving - plane method

    本文利用次線性項在零點附近的凹性和可積性，用移動平面法給出了一類次線性橢圓方程正解的對稱性
  2. A new waveguide made of changing a wide wall of a rectangular waveguide to a uniform curved wall is called conformal waveguide. a kind of expression of approximate solution for domain mode of the new waveguide, including symmetric, unsymmetric arc, parabolic arch, hyperbolic arch, elliptic arch, etc., is constructed by using boundary condition of mental waveguide, variational method and boundary element method. by using the equivalence principle, an approximate calculating formula for equivalent resonant conductance of a narrow longitudinal halfwavelength slot cut in the curved wall of the unsymmetric arcrectangular waveguide is derived, and the result is shown. although this solution is approximate, it can solve the problem in designing the slotted antenna of such conformal waveguide

    把矩形波導一個寬面外突成均勻曲面構成的新波導統稱為共形波導.利用金屬波導邊界條件、變分法、邊界元素法構造這種新波導中主模場的一種近似解表達式，包括曲面橫截線為對稱、非對稱圓弧，拋物線弧，雙曲線弧，橢圓弧等.然後根據等效原理，推導非對稱圓弧矩形波導曲面上窄的縱向半波長縫隙的等效諧振電導的近似計算公式，給出計算曲線.這種解雖然是近似的，但卻能解決這類共形波導縫隙天線的工程設計
  3. Finally, we consider a cascadic multigrid method for soiviag a nons. y mmetric elliptic differential equation with boundary conditions
