  1. Then, we use both the method of multiple scales and the galerkin approach to give the perturbation analysis of the governing partial differential equation

    綜合運用多尺度方法和galerkin離散法對橫向振動的非線性偏微分方程進行離散和攝動分析，得到了三種共振情況下的平均方程。
  2. On positive solutions of a class of first order neutral differential equations on time scales

    一類時間軸上的一階中立型微分方程的正解
  3. Differential visual attention scales directed by location versus semantic cue

    位置提示與漢字提示視覺注意范圍的腦機制差異
  4. The theory of time scales was introduced by stefan hilger in his phd thesis ( [ 1 ] ) in 1988 ( supervised by bernd aulbach ), it has been created in order to unify continuous and discrete analysis. hilger found many results concerning differential equations had carried over quite easily to corresponding results for difference equations. then he defined the dynamic equation on time scales, i. e. the domain of the unknown function of the dynamic equations is a time scale

    時間模（ timescales ）最早是由德國w rzburg大學的hilgerstefan在1988年提出的，當時他在導師berndaulbach的指導下完成博士論文（ [ 1 ] ） ，其主要思想就是把連續分析與離散分析統一起來，他發現人們對微分方程研究后往往又對相應的差分方程進行研究，而一般情況下兩者又可得到相平行的結論，於是定義了時間模上的動力學方程，即方程的未知函數的定義域是一個時間模。
  5. Many foreign mathematicians have respectively devoted to researching the hamiltonian systems, boundary value problem and the oscillation, the asymptotic behavior, the stability of the dynamic equation on time scales, such as erbe l, bonnet m, peterson a, agarwal r, d sl o, kaymakcalan b, lakshmikantham v etc. in general, the research methods they used are just as the following : firstly, we compare the method of differential equation and with the corresponding difference equation, then unite them, finally, extend the results to other time scales

    近十年來，時間模上的動力學方程的研究得到了較快的發展，國外不乏有許多數學大家erbel ， bohnerm ， petersona ， agarwalr ， d slo ， kaymakcalanb ， lakshmikanthamv等都分別致力於時間模上哈密爾頓系統，時間模上動力學方程的邊值問題以及時間模上動力學方程的穩定性、振動性、漸近性等方面的研究。總的來看大家所採用的研究方法大致都是把微分方程與差分方程研究方法進行比較、統一，然後再推廣到其它時間模上。
