三相電磁噴流之研究

為了解決steam free的問題，作者鄭力瑋 這樣論述：

摘要電磁噴流是一種運用磁流體力學(Magnetohydrodynamics, MHD)之概念，當給予電極板電能與固定磁場時，便可產生勞倫茲力，藉此推動導電流體。其優點在於致動原理簡易，且不需要依靠複雜的機械結構，便可實現推送之效果。常見的應用在微尺度之微動幫浦與大型船體無槳式推進器上，以往許多研究都著重在電場與磁場之設計與幾何構型的最佳化，而本研究透過實驗探討在電磁噴流中，電極板附帶產生電化學反應而生成氣泡所構成之多相噴流場。並藉由染劑與氣泡之方式發展一流場可視化之方法。本研究透過計算染劑之汙染面積並與數值模擬結果進行比較，發現在低電流時之預測流量結果較為相近。並定義一無因次參數為勞倫茲力雷

諾數(Re_L)，用以描述電磁噴流之流場型態，實驗結果透過定性觀察當勞倫茲力雷諾數(Re_L)大於1600時，噴流型態會發展成紊流的型式。透過無因次分析結果也顯示其噴流擴散角(θ)與氣泡佔比(Ag)有隨Re_L數增加而有上升之趨勢，且在Re_L數大於1600後，因流場型態轉變，擴散角與氣泡佔比也有明顯上升之現象。在最後討論使用鋁電極板對於電磁噴流之影響。

社群媒體成為政治論爭的煽動空間 : 用戶的網路煽動行為與語氣分析

為了解決steam free的問題，作者張家瑜 這樣論述：

自 2020 年爆發的新冠疫情，人們的外出行動因封鎖管制而受到諸多限制，這也導 致原本的政治論爭在網路空間益加活躍。像是在社群媒體溝通脈絡中，人們討論有關新冠 病毒源頭的議題，往往與支持「線上民族主義」的網路挑釁者掛勾在一起。當中國成為 冠病毒的起源地，並散播到世界各地之後，熱衷於民族主義的中國網民，常對來自不同國 家且抱持不同政治立場和社會觀點的網民進行網路攻擊和煽動行為，這樣的網路煽動行為 因新冠疫情更加嚴重，其他國家的網民也往往是透過這些充滿挑釁和煽動意味的網路言論 戰爭和社群媒體溝通，而有機會與中國網民有所接觸。本論文旨在探討中國與其他國家的 網民間因政治立場和社會觀點的差異而引發的

網路煽動行為，本論文針對社群媒體溝通脈 絡中，網路煽動言論的語氣和動機進行分析，並討論網路挑釁和煽動如何從社群媒體溝通 脈絡轉化為實際的政治行動。本論文首先針對來自台灣、香港和中國網民間的網路挑釁和 煽動言論進行語氣分析，接著分析中國網民與其他國家網民間的網路挑釁和煽動言論，關 注中國網民與美國網民和印度網民間的網路互動和煽動言論。本論文沿用 De Fina 提出的 「語氣分析」研究方法，分析 157 條網路挑釁和煽動言論，針對這些社群媒體溝通中的五 種語氣進行分析，包括:諷刺、和藹、咄咄逼人、中立和曖昧語氣。採用語氣分析和多模 態溝通的研究方法，本論文認為中國網民和非中國網民之間的網路攻訐很

大程度上受「文 化鄰接」或「意識形態歧異」兩種因素所影響，這不僅顯示中國網民和非中國網民之間的 網路挑釁和煽動言論很多集中在民族主義和意識形態差異的爭論上，也發生在不同國家的 網民間對共同華人文化認同上的爭論。本論文也說明網路煽動言論有部分源自生活日常中 的社會事件，並從網路空間的挑釁和煽動言論，進一步在現實世界中引發後續政治效應， 這些效應有些是來自政府官員、非政府官員和一般社會大眾: 然而，有些則停留於網路溝 通層面，並沒有後續政治效應。
