  2. So the sliding mode variable structure controller was discussed, which has strong robustness against the disturbance, and the chattering phenomenon inherited from vsc was taken advantage to regular valve vibration for the purpose of avoiding coagulation on it, while precision of level control can be almost unaffected. but for the reason of control limitation, especially the acceleration insufficiency, the continuous time quasi - sliding mode vsc for one class of controllable system, as the substitution of ideal sliding mode control system, which was impossible to implemented, was researched, including the three essentials, reaching condition in particular, and the chattering ex - pression was given. furthermore, the effect to quasi - sliding mode motion and chatter - ing expression by extent disturbance was also analyzed

    由於控制量相對受限制，並且主要體現在控制量加速不足方面，無法實現理想的滑模變結構控制，因此本文研究了一類能控系統在這種情況下的連續系統準滑模變結構控制，包括變結構控制三要素，尤其是到達條件；並且針對塞棒掛渣問題，給出了該情況下抖振的表達式；魯棒性方面，分析了外界擾動對準滑模運動的影響，並且給出了外擾作用下抖振的表達式。
  3.

    為正確的查找適當的住宅生產函數，以及其中對應的土地與資本之間的替代彈性，本文分別對常規的固定替代彈性模型（ ces ）與可變替代彈性模型（ ves ）加以估計。
  4. On the basis of displacement - time series of the slope, a nonlinear dynamic model is set up according to backus generalized linear inversion theory in this paper. due to the equivalence beween autonomous gradient system and catastrophe model, a standard cusp catastrophe model can be obtained through variable substitution. the method is used in analysis of displacement data of huangci landslide and wolongsi landslide and in understanding how slopes evolve before sliding. the result shows that the nonlinear dynamic model can make satisfactory prediction result. is it most important that there is a sudden fall of d, which indicates the occurrence of catastrophe ( when d = 0 )

    研究表明，滑坡變形失穩過程具有混沌和分維特性，可以用分形理論來研究滑坡預測問題，基於對任一連續函數，至少在較小的鄰域內可以用多項式任意逼近的數學理論，運用改進的backus廣義線性反演理論，以斜坡位移時間序列為基礎，反演了斜坡演化的非線性動力學模型。並利用自治梯度系統與突變模型的等價性，通過變量代換得到標準的尖點突變模型。
  5. Application of variable - substitution method to solving process of higher mathematics

    變量替換法在高等數學解題中的應用
  6. Because we are doing only textual substitution, c is not smart enough to rename our temporary variable if it conflicts with one of the arguments passed to it
