色同步再生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。Aim at the above key sticking point, this vice studies the some concerning in submission the settle the knowledge reasonsrlmprimis, the school wants to be positive to adapt to the solicit that community transform, setting out from the realistic subsistence in student, transfering the student the study the activity, abandonning the learn the mindjagain, further reinforce in school and the communication of the of household, aim at a domestic student ' s teach according to his ability ; the third, transform to come in the school training various factors that learn can pall to learn, this among them include the training object, teaching method, program creation, evaluation of one ' s performance tool, employed atmosphere, mental state health etc. several contents s ; ultimately, approval beak this on instructing the student transforms the learns the behavioral key role make above various operationses carried practical
從教師方面談，致使中專生厭學的原因是教師學習的停止，學術鉆研不夠，教學觀念與教學方法陳舊而直接影響學生學習。針對以上癥結，本次研究提出一些關于解決厭學問題的思考：首先，學校要積極適應社會轉變的要求，從學生現實生存出發，調動學生學習積極性，摒棄厭學思想；再次，學校進一步加強與家庭間的溝通，針對不同類家庭的學生因材施教；第三，改變學校教育中導致學生厭學的各項因素，這其中包括培養目標、教學方法、課程設置、考核方法、就業環境、心理健康等多項內容；最後，通過教師這一指導學生改變厭學行為的關鍵角色使上述各項工作貫徹落實。
