  1. Forced oscillation for a class of impulsive delay robin parabolic boundary value problems

    邊值問題的強迫振動性
  2. Just under this urgent consideration, based on the fact that self - oscillation can produce pulsation of flow, to influence the flow boundary layer, thus to increase convective heat transfer coefficient, it is necessary to devote to the mechanism of self - oscillation and apply it to a heat exchanger

    正是在這種迫切要求下，基於自激振蕩能產生脈沖流動而影響流動邊界層從而提高對流換熱系數來強化換熱的考慮，需要開展對自激振蕩的機理及其應用的研究。
  3. Important missing aspects are : turbulent flow, numerical discretization techniques specially the relevant and difficult topic of numerical treatment of advection and related numerical methods of solution, variable property fluids, boundary layers, stability, etc. rather, it focuses on more primitive and fundamental issues of numerical treatment of advective equation and proper formulation of initial boundary value ( ib vp ). numerical problems associated with advective dominated transport include spurious oscillation, numerical dispersion, peak clipping, and grid oriention. however, the key of numerical solution of three - dimensional advective problem is searching for a high - precision interpolating function, which can keep the computational stability and low damping

    3 、針對三維純對流方程提出了實用的擬協調單元模式，並與線性插值模式和協調單元模式比較后表明，在物理量大梯度變化的情況下，線性插值模式會產生較大的數值阻尼，導致解的失真；協調單元模式具有極高的計算精度和良好的計算穩定性，還可較好地克服數值阻尼，但由於計及物理量的二階導數項，計算工作量大，邊界條件給定尚存在一定的困難；而擬協調單元模式不僅具有協調單元模式計算精度高的優點，還避免了物理量的二階導數項，可大大地減少計算工作量。
  4. During one and a half century, oscillation theory of differential equations has developed quickly and played an important role in qualitative theory of differential equations and theory of boundary values problem

    一個半世紀以來，微分方程的振動性理論已經取得了迅猛的發展，在微分方程定性理論及邊值理論問題研究中佔有很重要的地位。
  5. Oscillation of solutions for a class of nonlinear neutral parabolic differential equations boundary value problem

    一類非線性中立型拋物微分方程邊值問題解的振動性
  6. 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。
