  1. In the theoretical description of grazing emission fluorescence, the mode of fluorescence intensity emitted from layered materials dependence of grazing angle is established by applying asymptotic approximations to double fourier integrals, and the theoretic calculation formula of fluorescence intensity from a thin layer is derived. by the derived expressions, the theoretic simulation curves of several thin layers on si substrate are calculated. in the experimental setup, the requirement of construction of the setup and some important parameters are brought forward

    最後，利用平穩位相方法建立了掠出射情況下薄層樣品產生的熒光強度和掠出射角的對應關系數學模型，推導了薄層樣品熒光強度理論計算公式，並以此為依據模擬計算得出了cr 、 fe 、 ti和ni等幾種以si作基底的單層薄膜樣品的熒光強度隨掠出射角變化的理論曲線。
  2. Theoretical analysis and experimental results indicate that algorithm ecfpcg1 and algorithm ecfpcg2 es - tablished by specifying parameters are much more efficient than the imth method, and roughly speaking, the relative efficiency of the algorithms versus the imth method tends to + 00 at the asymptotic formula inn / in3 when n tends to + 00

    理論分析結果表明：這兩個演算法比imth方法具有更高的效率，而且，演算法ecfpcg1的效率高於演算法ecfpcg2的效率。進一步地，演算法ecfpcg2與imth方法的效率比分別為問題維數n和目標函數復雜性嚴格遞增函數，而且這個效率比的下界隨問題維數n的增大以ln （ n ） ln3的速率趨于無窮大。
  3. By using elementary method, a new arithmetic function is studied, and an interesting asymptotic formula is obtained

  5. Different from the scattering theory used in the derivation of conventional generalized screen propagator, in this paper, a high order formula of generalized screen propagator for one - way wave equation is proposed by using the asymptotic expansion of single - square - root operator

    摘要不同於常規廣義屏傳播運算元的推導中使用散射理論，本文利用單平方根運算元的漸近展開，推導出了單程波方程廣義屏傳播運算元的高階表達式。
  6. By further discussing the asymptoticality of " medial point " for mean value theorem in some references, several new asymptotic estimation formula are obtained under weaker conditions, which unify and extend corresponding results in the references

    摘要對文獻中的「中間點」漸近性的有關結果作了進一步討論，獲得幾個新的在更弱條件下的漸近估計式，從而在很大程度上推廣了文獻中的相應結果。
