    並用模態分析的方法，將系統的偏微分方程模型轉化成了模態模型；研究了狀態反饋和獨立模態方法；進一步完善了軟體界面以及軟體功能；在實際系統中，應用狀態反饋演算法，有效抑制了懸臂梁在受到外界瞬時脈沖擾動和激振引起的一階、二階模態振動。
  2. The expression efficiency difference between ped5 and pcdhfrl, a vector utilizing cmv enhancer / promoter ( pcmv - ie ) for foreign protein production, was analyzed using human interferon - p ( ifn - ) gene and human secreted alkaline phosphatase ( seap ) gene as reporters. when analyzed in transient expression, ped5 showed a little more protein produciton than pcdhfrl. however, in continuous expression, when serum concentration was lessened to slow down cell proliferation, ped5 expressed 3. 1 times more reporter proteins than pcdhfrl, which implied that pef - io was less affected by cell cycle status in contrast to pcmv - ie, making ped5 a good expression vector for foreign protein production

    應用人-干擾素（ ifn - ）和人分泌型堿性磷酸酶（ seap ）基因作為報告基因，對含有巨細胞病毒即早期啟動子（ p _ （ cmv - ie ） ）的表達載體pcdhfr1和ped5表達外源蛋白的能力進行了比較，發現對于瞬時表達， ped5略好於pcdhfr1 ；在穩定表達中，通過降低血清濃度，使細胞增殖緩慢，這時ped5表達外源蛋白的能力較pcdhfr1高3 . 1倍。
