Oliver and the Night Giants

為了解決Polishing的問題，作者O’Meara, Kitty 這樣論述：

What would you do if three giants came to your bedroom window one night and invited you to help them fix the world? That’s exactly what happens to Oliver when he least expects it, in this very special bedtime story. Come along with Oliver and the Night Giants as they explore what happens when we all

ow our imaginations to lead the way!Oliver and the Night Giants begins when three giants appear in Oliver’s bedroom window one evening as he is drifting off to sleep. The giants convince young Oliver, a budding artist, to help them with their nighttime work of repairing the world. Oliver helps the

giants with a long list of nighttime tasks, from brightening the moon to polishing the stars, from adjusting mountains to creating snowflakes, from planting seeds to calming the sea. As he travels the planet and beyond with the Night Giants as an important part of their team. Oliver and the Night G

iants is written in the tradition of a classic children’s literature journey story. This thoughtful, poignant bedtime tale is an homage to the power of the imagination and the significance of valuing one’s dreams, and it is sure to be a favorite with children, families, and teachers. The timeless th

emes and vivid imagery make this story a pleasure to read aloud and for children to read on their own. Kitty O’Meara lives near Madison, Wisconsin, with her husband, Phillip Hagedorn, their five rescue dogs, three cats, gardens, and books. Formerly a middle school writing and literature teacher a

nd hospital and hospice chaplain, she is currently a spiritual director and has been a lifelong writer and artist. She has been called ＂the poet laureate of the pandemic＂ based on her wildly popular, widely circulated, and hopeful poem about the COVID-19 pandemic. That poem is illustrated and presen

ted in book form in And the People Stayed Home, her best-selling first print book, published by Tra Publishing. She is also the author of The Rare, Tiny Flower (Tra Publishing, 2021). PRAISE FOR KITTY O’MEARA ＂Kitty O’Meara is the poet laureate of the pandemic. . . . The poem has become shorthand fo

r a silver-linings perspective during the coronavirus outbreak.＂--O, The Oprah Magazine ＂She has given the world a small piece of joy.＂--BookTrib ＂A communal beacon of hope.＂--The Washington Post ＂She is challenging us to grow--to look inside, to listen deeply, to allow ourselves to think differentl

y, and ultimately, to create new ways of living on the planet.＂--Deepak Chopra, MD, author, Metahuman ＂A stunning and peaceful offering of introspection and hope...＂--The Children’s Book Review ＂O’Meara’s words come to life for future generations to...encourage everyone to find silver linings, think

differently and never lose hope.＂--B & N Reads Born in Genoa, illustrator Anna Pirolli moved to Milan to study illustration at the European Institute of Design, where she graduated in 2001. She has worked as a freelance illustrator and art director for companies such as Mondadori, Pearson, Vogue, M

TV, Kinder Ferrero, Telecom, Nickelodeon, Furla, Zecchino d’oro, Disney, following the creative process from concept to creation. She’s also a visiting professor at the Accademia di Brera in Milan, where she teaches design applied to the arts. Despite her love for traditional techniques, her artwork

is mostly digital. Ironically, her dream-like, suspended atmospheres often don’t look digital at all. Her first picture book, I Hate My Cats, written by Davide Calì, was published by Chronicle Books, and the illustrations from her latest book, Anonymouse by Vikki VanSickle (Tundra Books) won the Di

陽極氧化鋁膜/鋁線材微結構對電性之影響

為了解決Polishing的問題，作者王聖方 這樣論述：

導線結構大部分為外覆高分子PVC的金屬線，普遍不耐高溫、酸鹼、磨耗以及嚴苛氣候，PVC絕緣外層耐溫僅60℃，隨著PVC老化並脆化，絕緣性降低，陶瓷層優異的材料特性可以解決此高分子的使用限制，用以取代傳統導線，完全不會有過熱燃燒起火問題，本研究使用陽極處理氧化鋁，作為絕緣層，PVC體積電阻 >1012 Ω - cm ，但氧化鋁卻有 >1014 Ω - cm ，相差百倍。以鋁線為芯材，表面用陽極處理生成氧化鋁作為絕緣層，作法如下：鋁線當作陽極，陰極選取石墨板為惰性電極，草酸為電解溶液，通電使鋁線材表面氧化形成氧化鋁薄膜，其化學性穩定，不受酸鹼腐蝕，氧化鋁熔點2,072°C，即使500°C下，體積

電阻率仍有1014 Ω - cm ，介電擊穿電壓有18KV/mm，氧化鋁不可燃、耐酸鹼、幾乎沒有壽命侷限。習知陽極氧化鋁是高密度堆積六角形孔洞，可填塞色料發色，其孔洞緊密排列，且氧化鋁膜緊密附著在鋁基材，可完整均勻包覆鋁線，空氣中當電壓小於10000V時不導電，電阻為無窮大，但電壓大於10000V時，空氣就會被擊穿而導電，設計氧化鋁作為絕緣層，再有孔洞提供的空氣電阻，研究陽極氧化鋁當作導線絕緣層的可行性。以CVD和PVD在金屬上披覆陶瓷，難以避開披覆層剝落問題，本研究選用工業用純鋁，先研磨將鋁表層氧化層去除，再浸泡氫氧化鈉，為了清潔表面，接著浸泡硝酸溶液中和殘留氫氧化鋁，同時表面敏化，再以化學

拋光將表面平整化，以利於進行陽極處理時能平均分布電荷。鋁基材之表面粗糙度與化學拋光後表面粗糙度成正比，2000號砂紙研磨所得粗糙度為0.72μm，足以有利於後續氧化鋁生長，10%草酸50V生成之微結構孔洞小，且可生成厚度35.92μm，此厚度為最佳電阻>2000MΩ。因氧化鋁因成長張應力產生沿線材方向的裂紋，而在裂紋處電擊穿，雖然已達到高絕緣電阻，但裂紋缺陷有擊穿後電阻出現，其氧化鋁膜成長厚度約每增加10V之電壓，厚度增加1倍，使用兩段式陽極處理，第一段使用30V，第二段使用50V，經由第一段10min以上製造緻密表層，再加上第二段加速生長，以達到最佳絕緣，第一段30V陽極處理需要大於10mi

n，而第二段加速生長其需要大於30min才能生長出能抵抗1000V高壓之絕緣電阻，再經由披覆凡力水，先隔絕氧化鋁與大氣接觸吸收水份，並填補應力產生裂紋，達到最高絕緣電阻之導線，製作出來之AAO最高耐電壓1000V下接近∞，並進一步解決具氧化鋁外層導線的彎折裂開問題，撓曲90度仍能抵抗250V直流電壓，工作溫度達450℃。

Murder at Mallowan Hall

為了解決Polishing的問題，作者Cambridge, Colleen 這樣論述：

As head of household for none other than Agatha Christie, Phyllida Bright finds her position includes polishing silver, serving luncheons...and drawing inspiration from the crime author’s fictional detectives when mysterious deaths at Mallowan Hall baffle her famous employer...Tucked away among D

evon’s rolling green hills, Mallowan Hall combines the best of English tradition with the modern conveniences of 1930. Housekeeper Phyllida Bright manages the large household with an iron fist in her very elegant glove. In one respect, however, Mallowan Hall stands far apart from other picturesque c

ountry houses. For the manor is home to archaeologist Max Mallowan and his famous wife--Agatha Christie... Phyllida is both loyal to and protective of the crime writer, who is as much friend as employer. An aficionado of detective fiction, Phyllida has yet to find a gentleman in real life half as fa

scinating as Mrs. Agatha’s Belgian hero, Hercule Poirot. But though accustomed to murder and its methods as frequent topics of conversation, Phyllida is unprepared for the sight of a very real, very dead body on the library floor... It soon becomes clear that the victim arrived at Mallowan Hall unde

r false pretenses during a weekend party. And when another dead body is discovered--this time, one of her housemaids--Phyllida decides to follow in M. Poirot’s footsteps to determine which of the Mallowans’ guests is the killer. Now only Phyllida’s wits will prevent her own story from coming to an a

brupt end...

含矽丙烯酸水性船舶防汙漆和可調節式侵蝕探討

為了解決Polishing的問題，作者李旻燁 這樣論述：

目前應用於海運之傳統溶劑型船舶塗料不但會有溶劑汙染問題也因海洋生物及藻類附著於船體，使得船舶阻力上升並增加油耗量；因此文獻上發展出自拋光、結構釋放、酶基及表面微型工程等四類船舶塗料期望解決傳統船舶塗料所造成之問題。本研究擬結合具水解特性的丙烯酯類、矽氧烷樹脂及功能性粉末，研發具有自拋光、結構釋放和生物活性的環保水性船舶塗料。實驗設計以反應型乳化劑和甲基丙烯酸甲酯Methyl methacrylate (MMA)、甲基丙烯酸丁酯 Butyl methacrylate (BMA)、丙烯酸-2-乙基己酯 2-Ethylhexyl Acrylate (2-EHA)以及支(R)/直鏈(S)的矽氧烷單體

進行逐步添加之聚合反應，之後再加入氧化鋅、碳酸鈣、滑石粉、二氧化鈦、二氧化矽、蒙托土、氧化亞銅、DCOIT殺菌劑及分散劑等添加物，最後用鋯珠和機械攪拌分散，再噴塗塗佈厚度約為180微米塗膜進行硬度、百格試驗、水滴接觸角、粗糙度及侵蝕速率等分析。實驗結果顯示當使用R2矽氧烷時，塗膜鉛筆硬度可以達到9H，百格試驗達0~1級，水滴接觸角達132∘以及剝落速率24.5 µm/month。
