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 key 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。

製備適用模擬太陽光之氧化鉍/蒙脫石/二氧化鈦光觸媒降解揮發性有機物1,2-二氯乙烷之研究

為了解決Steam key free的問題，作者郭憲治 這樣論述：

本研究藉由蒙脫石摻雜於二氧化鈦製備不同比例之蒙脫石/二氧化鈦固定式光觸媒(MT)；透過UV-Vis、FE-SEM、XRD、XPS及FT-IR進行物理性質分析；並探討不同比例光觸媒於無氧環境之批次實驗系統以模擬太陽光/紫外光照射降解1-2,二氯乙烷成效；且探討於最佳成效MT光觸媒中加入氧化鉍製備氧化鉍/蒙脫石/二氧化鈦光觸媒(BMT)之成效。UV-Vis顯示BMT光觸媒皆具兩處吸收波長，且其中一處位於可見光波段；SEM顯示光觸媒表面無明顯變化且存在蒙脫石；XRD顯示光觸媒同時具銳鈦礦及金紅石晶相，且未觀察到其他雜質；XPS顯示MT光觸媒具Ti2p3/2及Ti2p1/2及Si2p元素，且BMT光

觸媒具有Bi2p7/2及Bi2p5/2元素；FT-IR顯示光觸媒具Ti-O、Ti-O-Ti、H-O-H、-OH官能基，綜合上述顯示成功製備改質光觸媒。由模擬太陽光光催化實驗結果顯示0.5BMT#(含有0.5 mol%氧化鉍及5 mol%蒙脫石之二氧化鈦)效果最佳，於135分鐘可達100.0%降解；紫外光光催化實驗結果顯示5MT#(含有5 mol%蒙脫石之二氧化鈦)效果最佳，於模擬太陽光照射下於97.5分鐘可達100.0%降解。經反應動力學推估，本研究模擬太陽光光催化實驗較符合一階反應模式；經耐久性實驗(連續五次光催化實驗)後，0.5BMT#仍維持80.9%降解率，表示具良好重複利用性；且由FT

-IR分析光催化產物顯示無明顯有毒副產物產生。綜合上述，本研究所製備之光觸媒於模擬太陽光可有效降解目標污染物1,2-二氯乙烷。
