  1. In succession, the theory of chirped - pulse amplifier system is given in detail, firstly, studying from designing experimental light road and optical components to theoretical analysis, we par ' tly finished the system by ourselves. about ultr a - shoft pulse with a pulse - width of 9. 8f s and output power of 650mw and band - width of about l 20nm is output from oscillator source, secondiy, the stretching capacity of single grating four - pass stretcher is measured using abcd matrix combining collins function, and the effect of relativ e parameters to the streching ratio is also simulated. thirdly, a new type of disjunctional frequency moduiating function is provided according to the gain - narrowing and gain - saturation which are appeared in the co urse of amplification, under modulating the two effects are both controlled on some e xtent, fourthiy, the effect of ase that is often ignored by people is analyzed and the resolving methods are also given

    從光路、光學元件的自行設計到理論分析計算,初步建立了一臺實驗系統;採用abcd矩陣法結合collins公式計算了四通式單光柵展寬器的展寬量,並模擬了相關參數對展寬比的影響,對實驗具有指導意義;評價了再生放大器和多通放大器的優缺點,對放大過程中通常忽略的放大自發輻射現象( ase )進行了分析,並提出了相應的解決方法;針對放大過程中出現的增益窄化和增益飽和現象,對輸入種子脈沖提出了一種新的分段頻率調制函數,實現了對增益窄化效應和增益飽和效應的共同抑制;提出了系統的材料(包括放大介質和光路中的普通介質)正是融合高階色散的來源。
  2. Electrical - controlled appliance includes single slice microcomputef, power supply, keyboard, liquid crystal display. the machine for body functional rehabilitation is controlled by enactment of five parameters, which are speed, range, position, frequency, time. the enactment of the five adjustable parameters used to realize six function that are anns stretching and circumrotating, wrist swing, finger stretching, crura anuckle stretching, anklebone swing

    將肢體運動康復機本身選用的六項功能用以下五個參數的設定來控制,即用速度、幅度、位置、頻率、時間這五個可調參數的控制來實現肢體運動康復機中上肢手臂伸屈、手臂旋轉、腕關節上下左右擺動、手指伸屈、下肢膝關節伸屈、踝關節上下左右擺動六個功能。
