本研究以食品級幾丁聚醣為殼材，檸檬精油為芯材，經由液中硬化法製備幾丁聚醣W/O型微膠囊，將濃度2.5%、3%、3.5%、4%、4.5%的幾丁聚醣膠體與染色後之檸檬精油以殼芯比10:1、15:1、20:1之比例混合，先以1000 rpm進行第一段分散後，再以8000 rpm~12000 rpm進行第二段分散形成懸浮液，分別滴入3%、5%、10%、20%之氫氧化鈉水溶液中進行交鏈，製成微膠囊，並以80℃之去離子水隔水加熱10 min，探討熱處理對微膠囊外觀成形性及釋放性之影響。本研究也發現經熱處理後之幾丁聚醣微膠囊，表面較未處理之幾丁聚醣微膠囊平整，而熱處理後之微膠囊表面孔洞有縮小之現象，且熱處理有利於減緩精油的釋放速度。

幾丁聚醣(Chitosan)被利用於製作微膠囊之殼材，因交鏈時間不同也會使得殼材性能及膨潤性差異，交鏈時間為30分鐘幾丁聚醣粒子膨潤性197.27%為最佳膨潤性，交鏈30分鐘以下成形性較不佳易破損使得粒子大小較不一致，本實驗利用電漿(plasma)改質於氫氧化鈉交鏈30分鐘之幾丁聚醣粒子，去探討其膨潤性變化，實驗中利用電漿氣體氬氣，電漿中氬氣擁有蝕刻特性明顯，使用此特性去增加幾丁聚醣表面積使膨潤性改變，實驗中氬氣電漿100瓦0.4分鐘為最佳數據247.35%，如提高氬氣電漿時間幾丁聚醣其膨潤性開始上升，至時間0.4分鐘後膨潤性開始下降，而降低瓦數膨潤性下降，提高瓦數膨潤性也下降，但降低50瓦較提高50瓦膨潤性還佳。

本研究以射頻(RF)電漿轟擊及表面蝕刻活化之方式處理明膠(gelatin)嘗試改變其親水性。實驗中以濃度10%的明膠製成微膠囊並使用氦氣、氬氣及氮氣電漿改質，探討電漿功率、電漿處理時間及水中溶解溫度的改變對其成形性的影響。實驗結果顯示，以惰性氣體氬氣進行電漿改質時明膠微膠囊表面產生活化點，破壞親水基團，而達到疏水效果。功率由30瓦到90瓦之間明膠微膠囊之溶解性有降低趨勢，但由90瓦到210瓦之溶解性趨於緩和。在改變電漿處理時間時發現，從1min到5min之間明膠微膠囊溶解性明顯降低，然而從5min到13min時之溶解性亦趨於緩和。明膠微膠囊之溶解時間與溫度的增加呈現反比趨勢，在30°C到40°C溶解時間樣本顯現之疏水效果最好。綜合前述，目前以電漿功率90瓦，電漿處理時間5min，水溫為40°C，能獲取疏水性最佳之明膠微膠囊。結果使用電子顯微鏡(SEM)觀測明膠微膠囊表面，及FTIR(傅立葉紅外線光譜儀)探討官能基團變化，並使用…

由於不同軟硬鏈段比例所組成的熱塑性聚氨基甲酸酯(Thermoplastic polyurethane, TPU)其物理性質及化學性質而也有所不同，因此熱塑性聚氨基甲酸酯被廣泛的應用在各個領域中。熱塑性聚氨酯因為具有較高的生物相容性及血液相容性，且物化性優良，所以在生醫的領域中也是常見的生醫材料。本研究主要是利用電漿改質技術將熱塑性聚氨酯Tecoflex○R93A、60D及68D進行表面處理，並利用接觸角測量儀測量熱塑性聚氨酯的表面親水性，結果顯示當電漿時間為5分鐘時93A、60D及68D的接觸角的變化量趨於相似，而電漿處理完一天後仍有較高的接觸角變化量，硬度最高之材料回升最不明顯。在白蛋白的測試結果中可以發現不同的電漿時間會影響白蛋白的貼附濃度，且薄膜成形時的接觸面也會影響薄膜的軟硬鏈段的分佈，經電漿改質後其白蛋白的濃度也會因接觸面而有所不同的變化。

本研究利用銅和碳纖維的導電特點，使用兩種纖維去製成平紋織物，並以銅線為經紗，碳纖維為緯紗，再以增加電磁波多重反射空間的材料，製成不同銅線隔距的織物，以及改變碳纖維根數方式與比較有無塑膠管對電磁波吸收值的影響。由實驗可得知，隔距1.5cm的試片電磁波吸收效果最好，吸收值在31dB，隔距小於1.5cm的試片由於張力大則空隙大所以不易造成多重反射干涉共振則吸收效果差，而經過不同碳纖維根數發現碳纖維根數6道的試片吸收效果最好，吸收值在33dB，經由有無塑膠管與固定銅線隔距的試片測試，發現有塑膠管的吸收值整體數值比無塑膠管的吸收值高。

本實驗在於是探討古典樂時期的音樂特性，並以鋼琴獨奏樂曲為樣本，利用電腦軟體與標準節拍器進行樣本樂曲三要素，節奏、振幅、音階之分析。從實驗結果可知在編曲及表現創作上顯示出一定的趨勢，速度越快是輕快的表現，速度慢是沉重的表現，振幅大情緒是鮮明激動的，振幅小情緒是平穩安靜的，音階高是愉快的表現，音階低是沉重、躊躇或疑惑的表現。

The purpose of this experiment is to explore characteristics of music during the classical period using piano-solo musics as samples. The three melody elements of these samples rhythm, amplitude and scale were estimated using computer software and metronome. The results indicate that there exists a tendency that both meanings of music composition and creative performance agree with each other well. In addition, fast rhythm pace coincide with enthusiastic behaviour while slow rhythm pace with serious behaviour. High and low amplitudes relates to excitement and peacefulness respectively. Hig…
