  1. The method is described as follows : the velocity of the moving part and the gas chamber pressure were measured with a dynamic test measurement system ; a dynamic model was built on force analysis of the moving part ; the total kinetic resistance replaced the horizontal friction and water resistance ; then the resistance - velocity relation curves at moving stages were obtained ; with the empirical formula of the gas chamber pressure and the resistance - velocity relation curves, the preliminary dynamic characteristics were analyzed and the structural form and key parameters of an underwater assault rifle were determined

    具體方法為：由動力學測量系統測得活動件速度和氣室壓力；分析活動件的受力，建立動力學模型；以運動總阻力代替水平方向上的摩擦阻力和水阻力，獲得各運動階段的阻力速度關系曲線；利用氣室壓力經驗公式和阻力速度關系曲線，對水下突擊步槍進行初步的動力學分析，確定其構造型式及主要參數。
  2. In our laboratory, a unique mutation detection system using a shuttle vector plasmid has been established to demonstrate that a low concentration of mnng ( 0. 2 m ) can induce nontargeted mutation in mammalian cells : the mammalian cells were exposed to 0. 2m mnng for 2. 5h, then a shuttle plasmid pz189 carrying supf trna gene was transfected into cells after 24h culture. we found a 5 - fold higher mutation frequency of the plasmid replicated in pretreated cells than the spontaneous mutation frequency of the plasmid replicated in control cells. this kind of mutation did not occur immediately after mnng exposure

    我們實驗室曾用一特殊的突變檢測系統，直接證明dna損傷劑可在哺乳動物細胞誘發非定標性突變：首先用低濃度（ 0 . 2 m ）的短壽烷化劑mnng （半壽期為1 . 1hr ）處理細胞2 . 5h后，繼續培養24h ，將重組有用作突變檢測的靶基因supftrna基因的穿梭質粒pz189轉入細胞復制，發現在未受致癌物直接攻擊的穿梭質粒中有較自發突變率高5倍以上的靶基因突變。
  3. Question bank of exam questions as part of test - on - demand provision
