  6. As the dispersive influence can be easily described by a frequency transfer function, the feasibility of measuring the function with the g - s algorithm is researched numerically in the next part. from the results of simulation with fibers with different length and pulses with different width, it ’ s known that the convergence of the algorithm is related to the difference between the input and output pulse. then, the influence of attenuation and self phase modulation of fiber is discussed, and the influence of the delay phenomenon and fitted polynomial is also analyzed

    通過對不同光纖長度和不同輸入脈沖脈寬的計算，得到了g - s演算法的收斂性與輸入波形和輸出波形之間的關系;在此基礎上，通過對光纖損耗、自相位調制的模擬，分析了損耗和自相位調制對光纖傳遞函數測量的影響;本文還分析了波形測量中的拖尾現象和多項式擬合對測量的影響，進而，對利用g - s演算法進行單模光纖傳遞函數測量的可行性進行了闡述。
  7. 2. the pre - flashover phenomena of alumina insulators in vacuum have been investigated. according to the experimental results, a reversed pre - flashover current was observed repetitively, which often occurs at the tail of pulse voltage close to zero ( sometimes after the applied pulse voltage )

    首次發現了大量的、重復性的反向預閃絡現象，即在沖擊電壓波尾附近電壓幅值已經接近零、甚至在沖擊電壓作用完后（已沒有電壓）的情況下仍然存在試樣表面發光現象，同時伴有反向的電流脈沖。
