  1. Principal conclusions were drawn as the following : the non compatibility of pressure or velocity of the gas on both sides of the contact surface is the cause of the formation of shock wave ; the heating effect of reflective shock wave to driving gas during charging or exhausting process is the internal mechanism of peak oscillating effect, and all the factors that influence the formation and the running of the shock wave will influence the peak oscillating frequency, cooling effect

    主要結論如下:熱分離機內激波形成的原因是射氣間接觸面兩側壓力和速度不相容;振蕩效應的內在機制為反射激波對充氣階段的驅動氣或低溫排氣的加熱,凡是影響激波形成及運動的因素都將對振蕩頻率、冷效應及熱效應產生影響;當充、排氣間比為0 . 1763,最佳射流激勵頻率出現在高階振蕩頻率上。
  2. Transient voltage spike

    電壓
  3. In this work, incident super - gaussian pulse propagation in conventional single - mode fibers has been investigated in detail after taking into account the fiber chromatic dispersion. the results show that for an incident super - gaussian pulse with steep leading and trailing edges, its shape undergoes a variation from near - rectangular, two - peak, and finally to single - peak. in the meantime, its peak intensity increases at first, after passing a maximum, and finally decreases monotonously

    模擬的結果表明:超高斯入射光脈沖在光纖中傳輸脈沖波形、惆啾、以及強度的演變規律與高斯入射脈沖不同,脈沖波形不再總保持單結構,通常將經歷一個從近平頂、多、最後到單的演變過程;從脈沖的前沿到后沿,明啾也不再為線性,而是具有多個極;強度隨傳輸距離的變化趨勢也不再為一單調遞減,而是先增加后減小。
  4. The working principle of pulsed eddy current ( pec ) nondestructive testing technology is analyzed, the pec testing system was been established to examined the specimen of multi - layered aircraft structure, peak and zero - crossing time of the time domain transient response signal of pec are extracted as the features to detect the corrosion in the second layer of aircraft structure quantificationally, the experiment results are consistent with that of the theory analysis, as the pec have the advantages of fast speed and quantification, this makes the method have the broad using foreground in the testing of aircraft structure corrosion

    摘要對脈沖渦流無損檢測技術的工作原理進行了分析,建立了脈沖渦流的檢測系統對加工的模擬飛機多層結構的試件進行了測試,提取其態感應信號的和過零間作為特徵量,對出現在飛機多層結構第二層中的腐蝕缺陷進行了定量檢測,試驗結果和理論分析相一致,證明了脈沖渦流檢測方法的有效性,由於其具有快速和定量化的優點因而在飛機結構的腐蝕檢測中具有廣闊的應用前景。
