然後在網路計劃中引入關鍵鏈原理從總體上考慮影響項目周期的不確定性因素，給出利用各種約束關系確定關鍵鏈的方法，並通過對實例的分析，探討了關鍵鏈對項目計劃周期的影響。 -
Through such a study, it is also shown that when the time delay is long enough such that the stability switches of the equilibrium of system halt, the bifurcation branches originated from the critical time delays cannot be surely stable or unstable in the whole solution space, that is, their stability depends on cases. this phenomenon also implies that the stability of the periodic solutions on the bifurcation diagrams indicates only the stability on the local center manifo ld. some distinguished features of delay dyn
利用打靶法的數值結果說明了當系統平衡點不再發生穩定性切換時，源自這些臨界時滯處的解支的穩定性在整個解空間的穩定性具有不可判定性，這也說明由多尺度法所得高階近似判定的解支的穩定性事實上只表示解支在局部中心流形上的穩定性，而非在整個解空間中的穩定性。 -
In this paper periodically perturbed hopf bifurcation to lienard equation with limited time delay is sdudied in detail. that is, the influence of small periodic perturbations on system exhibiting hopf bifurcation is sdudied. in particular, the excitation frequency and the critical natural frequency of hopf bifurcation in the cases of harmonic resonance. subharmonic resonance, ultraharmonic resonance, and ultrasubharmonic resonance is discussed. it is shown that in some parameter regions the sestyms exhibit harmonic solution bifurcation, subharmonic solution bifurcation, ultraharmonic solution bifurcation, ultrasubharmonic solution bifurcation and quasi - periodic solution
本文詳細研究了具有限時滯li nard方程的周期擾動hopf分支，即在該系統經歷hopf分支時，研究小周期擾動對系統的影響，特別是討論了擾動頻率與hopf分支周期解的固有頻率在共振、次調和共振、超調和共振、超次調和共振的情形。 -
At the same time, the dissertation discuss some important problems in simulation and verification in detail, such as hazards finding, inertia delay, feedback treatment, false paths discerning, setting up and holding time, critical path and shortest path
與此同時，本文還針對邏輯模擬驗證中涉及到的冒險檢測、慣性延遲、反饋處理、偽路徑識別、建立與保持時間、關鍵路徑和最短路徑等關鍵問題進行了詳細的論述，並分別設計了基於boole過程的演算法。 -
Afterwards, a duffing system with delayed displacement feedback is studied by the method of multiple scales and other numerical methods. the uniform formulas for computing the critical values of time delay are given and the global diagrams of bifurcation for the periodic solutions with respect to the time delay are obtained under different parametric combinations. it is shown that the hopf bifurcation and the saddle - node bifurcation are the only two types of bifurcation observed in such a system
接下來用多尺度法及數值方法研究了一具有時滯位移反饋的duffing系統的動力學，得到了不同參數下系統平衡點發生穩定性切換時的臨界時滯計算公式及關于時滯的大范圍hopf分叉圖，並發現saddle - node分叉及hopf分叉是系統出現周期運動的兩個主要的來源。 -

Based on internal rate of return as dynamic index of financial evaluation, the authors quantitatively analyse the critical point of investment inflation for a project, which can be explained as follows. assuming that the project is in a definite time limit during which the internal rate of retum should not be less than minimun attractive rate of return ( marr ), an analysis is made on the critical value of allowable maximum inflation of investment cost. similarly, assuming that the project is in a definite investment, an analysis is made on the critical point of allowable maximum delay of time limit for the project. by critical analysis of inflation of investment and delay of time limit for a project, an investigation can be made on the capacity for a project to bear the risk of investment inflation and time limit delay ; and then a scientific basis can be offered for arranging invesetment and drawing up schedule of construetion
根據建設項目財務評價的動態評價指標? ?內部收益率，定量地分析建設項目的投資膨脹臨界點.假設在工期一定情況下，研究分析項目的內部收益率應該至少等於國家規定的行業基準收益率時，其允許投資費用的最大膨脹臨界值.類似於投資膨脹臨界分析，假設在項目投資一定情況下，得到允許建設工期的最大膨脹臨界點.通過投資與工期膨脹臨界分析，可以考察投資項目承受投資增加和工期拖延的風險能力，為合理安排投資和編制施工進度提供科學依據 -
By using the method of dynamic analysis of origin neighboring region, the condition and the number of critical steps while no oscillating occurred in time delay systems are obtained
