  1. Light gas gun was used to create shock pressure. staged samples, cuneiform window with aluminium coat on the reflecting surface and visar ( velocity interferometer system for any reflector ) were employed in the experiments. polymethyl methacrylate and ofhc copper were assembled as the impactor to impact staged samples

    採用氣炮加載，利用臺階樣品、雙點式visar （ velocityinterferometersystemforanyreflector ）和鍍膜楔形窗口技術，以有機玻璃和無氧銅組合為飛片，碰撞無氧銅臺階樣品。
  2. Polymethyl methacrylate pmmmoulding materials

    模塑材料
  3. High energy explosive was used to create a powerful and planar shock wave for accelerating flyer plate to high velocity, and high pressure was produced when flyer impacting with the sample. in the experiments, the impactor was brass and target was ofhc copper. by measuring the shock wave velocities of hr2 steel, high - density glass, aluminium alloy ( ly12 / lf6 ), magnesium - aluminium alloy ( mb2 ), polymethyl methacrylate and air, shock pressure and release isentrope of ofhc copper have been obtained

    採用化爆加載、平面波發生器和空腔增壓技術，以黃銅為飛片，無氧銅為靶板，測量了抗氫鋼（ hr2 ） 、重玻璃（ sio _ 2 ） 、鋁合金（ ly12 lf6 ） 、鎂鋁合金（ mb2 ） 、有機玻璃（ pmma ） 、空氣（ air ）和無氧銅（ ofhccopper ）各阻抗匹配樣品中的沖擊波速度，上述材料的hugoniot狀態參數c _ 0 、均為已知，由此確定了無氧銅的沖擊加載壓力和等熵卸載后的狀態，得到了等熵卸載路徑。
  4. Acrylics ; polymethyl methacrylate

    聚甲基丙烯酸甲脂
  5. By mingling these four kinds of compounds with the monomer ( mma ) of polymethyl methacrylate, respectively, we prepared metal phthaloyanine / polymethyl methacrylate ( pmma ) composite materials which have nonlinear optical properties

    分別將四種化合物摻入聚合物單體（ mma ）中，制備出具有非線性光學性質的金屬酞菁/聚甲基丙烯酸甲酯（ pmma ）復合材料。
  6. The temperature distribution of the aluminum film and polymethyl methacrylate substrate are obtained in radial orientation and angular orientation at various time

    採用鋁薄膜和有機玻璃為基底的慢基底快塗層式組合，分別得到了不同時刻薄膜鋁和基底有機玻璃中的溫度場隨徑向和周向的分佈曲線。
  7. Then based on the principle for pcr, 20 - cycle continuous - flow pcr is designed using cad software. to the designed 20 - cycle continuous - flow pcr chip, a krf excimer laser ( direct write method ) is adopted as the fabrication technology, and the polymethyl methacrylate ( pmma ) is selected as the substrate. so the appearances of pmma surface etched before and after by 248nm excimer laser under different incident fluences are analyzed using sem

    為此在應用掃描電鏡和三維形貌分析儀對pmma表面被準分子激光刻蝕前後的形貌、刻蝕粗糙度以及單脈沖刻蝕率等進行詳細分析的基礎之上，總結出了準分子激光刻蝕pmma的宏觀規律和微觀刻蝕機制，提出了一種準分子激光刻蝕pmma的是光熱光化學以及羽輝共同作用的理論解釋。
