The Nature of Spring

為了解決Seal的問題，作者Crumley, Jim 這樣論述：

A BBC-serialized vision of spring, ravaged by climate change yet still astonishing, by Scotland’s leading nature writer.Spring is nature’s season of rebirth and rejuvenation. Earth’s Northern hemisphere tilts toward the sun, winter yields to intensifying light and warmth, and a wild, elemental be

auty transforms the Highland landscape and a repertoire of islands from Colonsay to Lindisfarne.Jim Crumley chronicles the wonder, tumult, and spectacle of that transformation, but he shows too that it is no Wordsworthian idyll that unfolds. Climate chaos brings unwanted drama to the lives of badger

and fox, seal and seabird and raptor, pine marten and sand martin. Crumley lays bare the impact of global warming and urges us all towards a more daring conservation vision that embraces everything from the mountain treeline to a second spring for the wolf.

Pearl of the Sea

為了解決Seal的問題，作者 這樣論述：

FROM THE AWARD-WINNING CREATIVE TEAM BEHIND THE FILMS KHUMBA AND SEAL TEAMPearl has always felt more comfortable in the sea than surrounded by the people in her sleepy South African town who always seem to let her down. But when a new friend from below the surface is taken by poachers, Pearl may

need a little help after all.Since her mother left, Pearl has spent more and more time in the ocean, fishing to help her father pay the bills. But when she gets mixed up with a group of illegal abalone poachers and starts diving near a restricted wreck, Pearl meets an ancient sea monster named Otto-

-who isn’t quite as monstrous as she thought. And when Otto’s enemies come back to finish what they started, Pearl is the only one who can save him, but only if she has the courage to let go of her past and open up to others--including the girl from class she’s got a crush on. With her one-eyed pup

sidekick and a whole lot of nerve, Pearl may just be able to save Otto and finally tell the truth to her father... and, more importantly, to herself. With vibrant full-color illustrations, Pearl of the Sea is a South African adventure story exploring how we are both bound to and freed by nature, see

n through the eyes of a tough teen-aged heroine determined to live life by her own rules.

銑削加工表面粗糙度之最佳化分析

為了解決Seal的問題，作者鄭閔文 這樣論述：

在航空工業中，飛機引擎於高溫高壓的旋轉之下，機件上的瑕疵所造成的損傷皆會被放大來看，而發動機的壓縮機構表面要求更為嚴峻。因此相較於其他的產業，零件的表面要求也更加嚴格。當表面達不到需求或有一小段刮痕時，對於引擎的運轉上可能就會造成極大的飛安事件。不同的表面粗糙度，應用的引擎區域也有所不同，針對不同的表面粗糙度，加工的方式也有所不同，一般車床銑床的表面粗糙度相較磨床之下可以高出很多，通常加工完的表面都會有些微的切削痕跡，也就是我們常說的刀痕，而這些刀痕也和加工的參數息息相關。對於銑床來說，刀具業者會提供銑刀的加工參數，但基於材料、硬度、加工環境等不同的因素下，必須調整加工參數使零件有良好的表面

粗糙度。但在遇到表面粗糙度低的表面時，加工刀具的參數更是要測試多次才有可能測試出需求的表面粗糙度。為了有效減少開發時間與測試件的成本，本文將加工參數透過有限元素分析軟體ANSYS模擬零件加工的表面、應力、應變等情況後，再比對實際加工的表面參數是否與模擬的結果吻合。研究結果顯示，對於夾持的接觸面積來說面積越大，所得到的表面粗糙度及震刀越小；刀長的長度越短，粗糙度與震刀痕跡也越小；在有效率的進給條件下，進給越少，表面粗糙度及震刀痕越小；刀具轉速在適合的範圍內越快，其表面粗糙度及震刀痕會越低。
