    一片小翼的形狀可以是通過它上方的氣比通過它下方的氣流速度更快,從而產生下壓力。
  2. The pollution problems of the rivers and streams in that region have accordingly improved considerably in the past decade. however, as the base flow of local rivers and streams is generally small, their assimilative capacity is therefore low. this, coupled with the continued development and hence population growth in the river catchments, as well as the lack of maintenance of many private septic tank systems, has caused the water quality of some rivers and streams in the northwest new territories to remain unsatisfactory

    而溪的污染情況在過去的十年間亦因此而有所改善,但由於本地河溪的流速相當慢,河的自凈能力相對偏低,而河溪的周邊不斷發展,人口持續增加,加上部分私人的化糞池系統欠缺打理,未能有效運作,所以新界西北仍有部份河溪水質未如理想。
  3. First, it is compressible and cushiony ; second, it can be transported to a long distance with a little power loss ; the last, its flux and velocity of flow are quite high, so the reaction time of the operators can been considerably shortened. aiming to solve the problems of vibrating machinery such as short life - span, poor cushion and high energy consumption, the writer, on the basis of characteristic of pneumatic mentioned, contrives a set of valve controlled pneumatic vibrator, which has larger output vibrating force and longer life - span with simple structure. then, it is applied to drive a vibrating screen and the result is fairly well

    文中針對氣動技術本身的特性及優點,如:可壓縮,具有緩沖性;能耗損失小,便於遠距離輸送;量大、流速高,執行元件響應度快等,以解決振動機械在應用過程中的緩沖、能耗以及使用壽命等問題為目的,設計出一套輸出激振力大、結構簡單、使用可靠的閥控氣動激振器,並將其成功地運用到振動篩上,取得了較好的效果。
  4. In this dissertation, through computer simulation, the problems of modeling, control and guidance of auvs are presented. the first part of this dissertation addresses the problem of dynamically modeling of auvs, and derives thrusters " two - dimension nonlinear dynamic model, which has axial flow speed and propeller rotational velocity as two state variables, voltage or current of motor as inputs, and thruster force and torque as output. the second part focuses on the nonlinear adaptive sliding mode control of auvs in diving plane and steering plane
