  1. The research result demonstrates that along with the increment of reynolds number, the root mean square value of outer fluctuating magnitude of the external diameter in fall frequency band increases, the root mean square value of fluctuating magnitude of the external diameter in high frequency band decreses, demonstrating that the fluctuation of flexible pipe wall changes fluctuation don field of original rigid pipe, large - size eddy motion increases and small - size eddy motion decreases, this reduces energy loss and increases friction reduction effectiveness

    研究結果表明：隨著雷諾數的增加，全頻帶的外徑脈動的均方根值加大，但高頻帶外徑脈動的均方根值減小，說明柔性管管壁脈動確實改變了原剛性管的脈動流場，大尺度渦的運動加劇，低尺度渦運動減弱，從而使得能量損失減少，減阻效果增大。
  2. This paper presents an investigation on a new type of rubber damper, that is, a rubber damper with honeycomb structure. the honeycomb structure will enhance the energy dissipation of a rubber damper and as a result increase the damping of the damper. the performances of honeycomb dampers are experimentally tested by a test rig. the results show that the diameter and the density of holes of the honeycomb structure are important parameters in the design of the damper. for a damper of given size, there are optimum values of both parameters with which the damper provides highest damping. additionally the honeycomb structure does not change the correlation of damping to frequency. a practical honeycomb damper is designe d and applied to inlet pipe of a screw compressor in a petroleum factory for vibration reduction. the vibration of the pipe is obviously suppressed by the damper, at least 25 %

    本文採用理論分析和實驗相結合的方法，研究了蜂窩孔這種結構因素對橡膠阻尼材料阻尼性能的影響。在自行設計、製作的懸臂式阻尼測試實驗裝置上，對蜂窩式橡膠阻尼器的阻尼性能進行了大量的實驗測試，初步找出了蜂窩孔孔徑、孔數以及預壓縮量等因素與阻尼器阻尼性能的關系。本文利用實驗研究的結論，設計了一種專用的蜂窩式橡膠阻尼器，並應用於某廠螺桿壓縮機進口管道的減振，取得了明顯的減振效果。
  3. During the initial pan - milling period ( 1 - 5 milling cycles ), a sudden particle size reduction was observed, which can be described by " avalanche " pulverizing mechanism, i. e., large amount of energy caused by pan - milling press force accumulated in deformable polymers to a critical point and then the deformed polymer flakes suddenly collapsed to small particles by shear force

    結果表明，在碾磨初期（ 1 5碾磨循環） ，聚合物粒子的粒度有一個驟降過程，是磨盤強大擠壓力場作用於塑性材料引起的能量積累達到其破壞極限后引起的突然破碎，可用均一粉碎機理描述。
