  1. This dissertation focuses on how to develop a high performance damping mechanism based on multi - energy transitions, which is independent or little dependant with the viscoelasticity of polymer matrix. three sections are mainly included in this dissertation as follows : chlorinated polyethylene ( cpe ) / piezoelectric ceramic ( pzt ) / vapor grown carbon fiber ( vgcf ) composites ; cpe / 2, 2 ' - methylene - bis - ( 4 - methyl - 6 - cyclohexylphenol ) ( zkf ) / vgcf composites ; organic hybrids made from cpe and small molecules cpe / pzt / vgcf composites : the damping composites of multi - energy transitions mechanism were produced by mixing pzt and vgcf into cpe. in this system, the mechanical vibration energy that was transmitted to cpe was found to convert into joule ' s heat through conduction paths between vgcf in the polymer matrix, so the vibration fades away

    本論文主要包括三個方面的研究內容： ?氯化聚乙烯（ cpe ） /壓電陶瓷（ pzt ） /氣相生長碳纖維（ vgcf ）復合材料； ? cpe /雙[ （ 2 -羥基- 3 -環己基- 5 -甲基） -苯基]甲烷（ zkf ） / vgcf復合材料； ? cpe基有機小分子混雜型復合材料cpe / pzt / vgcf減振復合材料：利用壓電和導電填料填充高聚物基體，當復合材料受到機械振動時，通過高聚物基體將機械振動能傳遞到壓電陶瓷粒子上，利用壓電陶瓷的壓電效應，將機械能轉換成電能，則電流在導電粒子產生的迴路中流動，由於導電迴路具有一定的電阻，所以電能又轉變成熱能耗散掉，從而起到減振的目的。
  2. Result of numerical simulation shows that the grads of continuous phase " s velocities decreases with the presence of microbubble of which the diameter is 100 / / w, the profiles of air volume fraction in the boundary layers is similar to triangle or echelon, affected by interaction among the particle, there is a saturated air fraction, within the scope of saturated air fraction, increasing the air injection ratio can accrete the friction reduction ratio, under the condition of same air injection ratio, the free - steam velocity is larger, the effect of friction reduction is worse

    計算結果表明，直徑為100 m的微氣泡能減小近壁面連續相的速度梯度；微氣泡在邊界層中的濃度分佈近似為三角形或梯形分佈；受粒子間相互作用的影響，存在一飽和濃度；減阻率隨噴氣量的增大而增大，直至飽和噴氣量，此後，增大噴氣量，壁面摩擦阻力變化不大；相同噴氣量下，來流速度越大，減阻率越低。
  3. The same with normal metal film, fe0. 3cu0. 7 ( 500nm ) granular film have positive coefficient of temperature. the negative resistance is observed in fexcu ( 1 - x ) granular film under certain condition. this characteristic of negative resistance is weakened or changed to positive with the change of thickness of film, ratio of fe atom to cu atom, anneal, test temperature

    N ） fecu顆粒膜月一i特性研究發現，極小電流下電阻測量具有不確定性； fe cu矚00川）顆粒膜己與普通金屬薄膜一樣，具有正的溫度系數； f民c山x顆粒膜在一定條件下存在負阻現象，並且隨顆粒膜厚度、鐵銅原子比、退火條件、溫度的改變分別存在負阻特性的減弱或向正阻特性的轉變。
  4. With the content of iron carbide in carbonyl iron decreasing, and rise, and shear stress ( at ) induced by magnetic field of mrs declines, the shear rate corresponding to the maximum at ( " y max ) heightens, and the response time of a t shortens. with the content of dmf increasing, the size of carbonyl iron reduces so that a t of mrs enhances, and increases with h more rapidly and " y max heightens

    隨著羰基鐵粒子碳化物含量的減少， 、增加，而mrs的磁致剪切應力下降，最高剪切速率_ （ max ）增加，磁流變響應時間縮短；隨著dmf用量的增加，羰基鐵粒子的二次顆粒尺寸減小， mrs的增加，且隨外加磁場強度h增加的速率提高， _ （ max ）提高。
