  1. We judged we could make miles enough that night to get out of the reach of the powwow we reckoned the duke s work in the printing office was going to make in that little town ; then we could boom right along if we wanted to

    公爵在那個小鎮上印刷店裡乾的那一套,一定會引起一場大鬧,不過我們斷定,我們當晚會走出去離鎮好幾英里路遠,那場吵鬧就跟我們無關了只要我們高興,我們完全可以一帆風順向前開了。
  2. The analysis results show that the palcement styles and the rotating angles of such a large scale deployable boom systems are functional importantly. the motions and damps of the boom systems also take importance. if motions become larger, the time for the booms to reach their spreaded states is shorter, and the impact velocities become larger, the impact accelerations become larger too

    分析結果表明,對于大尺度的伸桿機構,其布置方式和展開角度對其展開運動有重要的影響;同時也研究了鉸鏈處外力矩對展開運動的影響,隨著該力矩的增大,伸桿到達鎖定狀態的時間減少,碰撞時的速度增加,由此產生較大的加速度;分析了伸桿彈性和阻尼對伸桿展開過程的影響,彈性增大碰撞加速度增大,阻尼增大加速度減小,因此可將鉸鏈處外力矩和伸桿阻尼作為伸桿展開運動調節的手段。
