  1. Dynamic characteristic of the fan system was tested in this paper. the time constants of acceleration and deceleration was gotten and bode diagram of frequency response was presented. the results show that the frequency response of the system is satisfying in the range up to 0. 2 hz

    本文對風機系統的動態特性進行了測試，得到了它的加減速時間，並通過譜分析法得到了系統的幅相頻響應曲線（ bode圖） ，結果表明系統在低於0 . 2赫茲范圍有較好的相應特性。
  2. Design engineers now selecting pmbldc motors over conventional dc or induction motor drives for the following reasons : 1 ) the absence of brushes results in an essentially maintenance free operation and eliminates the undesirable effects of commutation such as sparks, brush - loss, radio - frequency interference, etc. 2 ) the low inertia of the rotor enhances the quality of the mechanical response of the motor, shortening the acceleration and deceleration time. 3 ) utilizing rare - earth permanent magnet materials with high coercive force results in substantially higher efficiency than their counterpart with brushes of the same size. 4 ) because of the absence of commutation segments, the stator construction is simple

    現在的工程師們更為青睞永磁無刷直流電動機是因為以下幾點原因： （ 1 ）去除了電刷的永磁無刷直流電動機徹底地免除了維護而且消除了我們不希望的由於換向帶來的火花、電刷損耗以及無線電干擾等等； （ 2 ）低轉動慣量的轉子提高了電機機械響應的質量，從而縮短了電機加速和減速的時間； （ 3 ）高矯頑力稀土永磁材料的使用使得同樣尺寸的永磁無刷直流電動機比傳統的直流電動機效率高； （ 4 ）由於沒有機械換向部分定子的結構簡單了。
  3. Most of the real - time tasks are controlled by pmac, such as scanning, interpolation, position control, acceleration and deceleration, input & output, writing the sampled points to the dpram and so on

    下位機完成掃描跟蹤控制、插補運算、位置控制、加減速控制、面板和機床狀態的輸入輸出處理等實時性任務。同時將工件表面坐標實時寫入dpram 。
  4. According to car following data under special traffic and road condition, rule of driver reflect time were gain in start acceleration car following phase and deceleration brake phase

    利用在特定的交通條件和道路條件下獲得的跟車數據，針對起動加速跟車狀態和減速停車跟車狀態，得到這兩種狀態司機反應時間的規律。
  5.

    文章以平均加速度為指標，利用動態聚類的方法，把城市快速道路交通流中的跟車行為劃分為三種狀態進行討論，即起動加速跟車狀態、穩定跟車狀態、減速停車跟車狀態。
  6. The deceleration lane gives you time and space to begin to reduce your speed

    減速行車讓你有充分的時間及距離減速。
  7. Once collision accident occurred when the train is moving with fairly high speed, the energy - absorbing structure produces large plastic deformation along the direction needed to absorb sufficient energy, at the same time, the deceleration must be controlled within the endurable limits to human body

    當列車在正常運行時，車體有足夠的強度和剛度，需要滿足有關規范規定的強度、剛度要求；在較高速下發生碰撞事故時，吸能結構能夠沿所需方向產生塑性大變形吸收足夠沖擊動能，保證機器間和乘客區不發生破壞，並延緩碰撞作用時間，降低碰撞瞬間最大減速度，使撞擊減速度在人體承受范圍內。
