    摘要闡述了聲波變密度測井時對其進行測前、測后線性刻度及記錄時差曲線的必要性。
  2. According to the different require of the phase mask, the holographic recording method for the design of linearly chirped phase mask is studied in this paper. the fringe formed by the interference of two spherical waves, whose density varies linearly with space, is used to record the chirped phase mask. the two design schemes proposed in this paper are analyzed and compared, and the experimental results are given

    根據光纖光柵掩模的不同要求，研究討論了用全息干涉方法製作線性啁啾位相掩模的設計方法，提出用兩球面波干涉產生條紋密度隨空間距離線性變化的干涉條紋記錄啁啾位相光柵，分析比較了文中給出的兩種設計方案，給出了實驗驗證結果，並且製作了線性啁啾光刻膠掩模。
  3. Variable density track record
