  2. 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公式計算了四式單光柵展寬的展寬量,並模擬了相關參數對展寬比的影響,對實驗具有指導意義;評價了再生和多的優缺點,對過程中常忽略的自發輻射現象( 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(包括介質和光路中的介質)正是融合高階色散的來源。
  3. Diesel particulate filter ( dpf ) is currently an effective and widely used approach to trap the particulate materials of diesel exhaust emissions

    對于柴油機微粒排的控制,目前遍採用的是柴油機微粒過濾( dpf ) ,過這種方式能除掉絕部分的碳煙微粒。
  4. The average gain and nf are 22. 22db and 8. 69db respectively. gain flatness under single and double lasers control are 0. 69db and 1. 51db. a gain - clamped dual - stage l - band edfa by utilizing backward c - band ase as control light is presented for the first time

    2 .我們還提出了一種優化反射式edfa噪聲性能的方案,過利用高雙折射環鏡代替光纖環鏡來抑制鉺纖的前向ase ,雙在1580 . 84nm ~ 1588 . 48nm范圍內的平均噪聲系數減少了3 . 7db 。
  5. Background is high resolution moving picture. the working principle is like midi karaoke player. but the defect of midi is obvious, midi music is pure musical instruments play combination, expression ability be got restriction. now, with the advance of technology, will use the form of mp3 lyric karaoke songs to replace the form of midi, the song files playing have realized original sing, to improve the amusement of karaoke. make mtv sing more to be fill with expression, another, the price is cheap, below with midi karaoke player product of same class. becase support cd vcd dvd jpeg mp3 mpeg4 disc form moreover, so apply extensively

    這款點歌機主要的特點是支持mp3走字字幕格式的mtv歌曲文件,背景是連續滾動播的高畫質視頻,類似於midi點歌機的工作原理,但是midi的缺陷是現而易見的,它的音樂是純樂音符的演奏組合,表現能力就受到了限制,隨著技術的進步,用mp3走字的方式來替代midi走字的方式演義卡拉ok歌曲,歌曲文件的播就實現了原聲原唱的要求,提高了卡拉ok的娛樂性,使mtv演唱更富有表現力,另外,性價比也較突出,價格總體要低於同檔次的midi點歌機產品,由於同時兼容cd vcd dvd jpeg mp3 mpeg4碟片的播,具有廣泛的適用性,所以是家用娛樂設備的不二選擇。
