  1. In the positioning servo - system, which generally is configured by the d. c. pulse width modulator ( pwm ) velocity governing system and position servo - loop, the parameter perturbance of pwm velocity loop really exist by reason of such as the load behavior ; power voltage supply ; operating setting value, etc. 1, 2 ， and it cannot be ignored. by using the identification technique to form the mathematical model of the system, authors have confirmed the facts. therefore, to design the discrete sliding mode controller ( dsmc ) of the positioning servo - system, the perturbed parameters value bounds of the pwm velocity loop, which is as the controlled plant of position servo - loop, should be accounted. consequently, the design principle of dsmc for accounting system with parameter perturbance is proposed by the authors. the proposed method can ensure the stability of system with parameter perturbance and the behavior of non - overshoot, fast precise positioning. in order to reveal the effects of the design method, the comparative research work is done by the authors. also, it has been tested in an industrial experiment, the results proved it is satisfactory

    由直流脈寬調速系統（ pwm ）和位置環構成的定位系統中，速度環的參數隨負載特性；電網電壓；給定工況而攝動是不容忽視的.作者通過系統辨識建模也證實了這一事實1 ， 2 .因此在設計位置環的離散滑模控制時，必須針對速度環（即位置環的控制對象）的參數攝動范圍採用「對象參數攝動離散滑模控制器的設計方法」 ，以確保系統在參數攝動時的穩定性和快速、無超調、準確定位的優良動態品質.為剖析該設計方法的控制效果，本文作了對比性研究，並將該設計方法用於工業試驗中，取得了滿意的結果

  4. Accorded to the experimental research, under different flow area of flow valve and different adjusted pressure of relief valve, conclusion that the regulation of the pressure p1, p2 in the two cylinder chambers varied with the change of step load were as follows : when the throttle valve was series - connected on the return oil - line in the metering - out control system, under the same flow area and the same adjusted pressure of relief valve, with the incremental quantity of step load, the pressure highly - adjusted capacity of the hydraulic cylinder chamber with piston - rod decreased, meanwhile, it ' s time of rise, time to peak and the governing time all decreased. while the pressure highly - adjusted capacity of the hydraulic cylinder chamber without piston - rod increased

    通過試驗研究得出系統在不同的流量閥開度、不同溢流閥調節壓力（進口壓力）下，液壓缸兩腔壓力p _ 1 、 p _ 2隨階躍負載變化的規律：當出口節流調速系統的回油路上串接節流閥時，隨階躍負載的增加，在相同流量閥開度、相同溢流閥調節壓力的情況下，液壓缸有桿腔壓力p _ 2 （ t ）的超調量是減小的，上升時間、峰值時間以及調整時間也是減小的；液壓缸無桿腔壓力p _ 1 （ t ）的超調量是增加的。

  6. From the experiments, the number and width of fracture are obviously decreased, and pasting cfrp laminates play important role in improving rc construction durability ; with anchoring, premature is prevented and the ultimate shear capacity is increased ; taking properly anchoring measure, the ultimate shear capacity of rc t - section beams of initial loads is higher than that of no initial loads ; under non - anchoring case, because the rehabilitation of rc t - section beams with cfrp laminates are destroyed suddenly, the reinforcement effect maybe decrease

    試驗結果表明，粘貼碳纖維布顯著減小了鋼筋混凝土t梁的裂縫數量和寬度，抑制了裂縫的開展，對提高普通鋼筋混凝土構件耐久性有重要作用；採用適當的錨固措施可以有效防止構件發生早期破壞，提高構件的極限抗剪能力；對于有錨固的粘貼方式，有預加載的t梁抗剪極限承載力明顯高於無預加載的t梁。試驗還表明，在無錨固的情況下，用碳纖維布作抗剪加固后的t梁破壞較突然，有可能使梁的加固效果出現負效應。
