The Land Beneath the Ice: The Pioneering Years of Radar Exploration in Antarctica

為了解決Thickness的問題，作者Drewry, David J. 這樣論述：

A wondrous story of scientific endeavor--probing the great ice sheets of AntarcticaFrom the moment explorers set foot on the ice of Antarctica in the early nineteenth century, they desired to learn what lay beneath. David J. Drewry provides an insider’s account of the ambitious and often hazardou

s radar mapping expeditions that he and fellow glaciologists undertook during the height of the Cold War, when concerns about global climate change were first emerging and scientists were finally able to peer into the Antarctic ice and take its measure. In this panoramic book, Drewry charts the hist

ory and breakthrough science of radio-echo sounding, a revolutionary technique that has enabled researchers to measure the thickness and properties of ice continuously from the air--transforming our understanding of the world’s great ice sheets. To those involved in this epic fieldwork, it was evide

nt that our planet is rapidly changing, and its future depends on the stability and behavior of these colossal ice masses. Drewry describes how bad weather, downed aircraft, and human frailty disrupt the most meticulously laid plans, and how success, built on remarkable international cooperation, ca

n spawn institutional rivalries. The Land Beneath the Ice captures the excitement and innovative spirit of a pioneering era in Antarctic geophysical exploration, recounting its perils and scientific challenges, and showing how its discoveries are helping us to tackle environmental challenges of glob

al significance.

運動訓練與停止訓練對中老年人骨骼肌氧合能力與身體功能表現之影響

為了解決Thickness的問題，作者杨永 這樣論述：

運動是一種改善中老年人骨骼肌氧合能力、提高肌肉力量並最終影響整體身體功能表現的有效方式。然而，較少的研究評估不同運動類型之間訓練效益的差異。此外，由於中老年人生病、外出旅行與照顧兒童等原因，迫使運動鍛煉的中斷。如何合理安排運動訓練的週期、強度與停訓週期，以促使中老年人在未來再訓練快速恢復以往訓練效益，目前亦尚不清楚。本文以三個研究建構而成。研究I：不同運動訓練模式對中老年人的骨骼肌氧合能力、肌力與身體功能表現的影響。以此探討50歲及以上中老年人進行每週2次為期8週的爆發力、阻力訓練以及心肺訓練在改善中老年人肌肉組織氧合能力、與肌肉力量身體功能效益的差異。我們的研究結果表明：爆發力組在改善下肢

肌力、最大爆發力與肌肉品質方面表現出較佳的效果。心肺組提高了30s坐站測試成績並減少了肌肉耗氧量，從而改善了中老年人在30s坐站測試期間的運動經濟性。年紀較高的肌力組則對於改善平衡能力更加有效。此外，三組運動形式均有效改善了中老年人人敏捷性。研究 Ⅱ：停止訓練對運動訓練後中老年人肌力與身體功能表現的影響：系統性回顧與meta分析。本研究欲探討停止訓練對運動訓練後中老年人肌力與身體功能表現訓練效益維持的影響。我們的研究結果表明：訓練期大於停止運動訓練期是肌力維持的重要因素。若訓練期

Robotic Non-Destructive Testing Technology

為了解決Thickness的問題，作者Xu, Chunguang 這樣論述：

The content of this book includes a variety of nondestructive testing (NDT) methods, with many introductions to testing and application cases. The book proposes new ultrasonic testing technology for complex workpieces. It is hard for traditional NDT technology to realize the automatic detection o

f complex curved components, especially the automatic high-precision nondestructive detection of curved-surface components with variable curvature, variable thickness and complex contour. Therefore, the robotic NDT technique as a combination of manipulator technique and NDT technique can further imp

rove the efficiency and accuracy of NDT. Robotic NDT Technique combines the physical principle of nondestructive testing with the flexible motion control of spatial attitude of articulated manipulator. With NDT as the constraint, it controls the motion attitude and azimuth angle of a transmitting an

d receiving transducer. Thus traditional NDT technique has developed from plane to curved surface, from 2D to many dimensions and from artificiality to intelligence, into a unique and systematic interdisciplinary robotic NDT technique.

少數層二硒化鈀之電性傳輸與熱電性質

為了解決Thickness的問題，作者李天任 這樣論述：

尋找高效率的熱電材料是一個重要而有趣的課題，二維 (Two-Dimensional, 2D) 過渡金屬二硫化合物 (Transition Metal Dichalcogenides, TMDC)，因其優越的熱電性能以及未來廣闊的應用前景而受到廣泛關注。其中，二維二硒化鈀 (PdSe2) 因其理論上計算出高熱電性能，吸引了眾多科研工作者的目光。本實驗使用機械剝離法，剝取少數層PdSe2，利用半導體製程技術製作少數層二硒化鈀的場效電晶體與熱電元件，在室溫下研究了二硒化鈀的電性。本實驗中，二硒化鈀為n型半導體材料，電流的開關比 (On/Off Ratio) 約爲104，臨界擺幅 (Subthre

shold Swing, S.S.) 約爲9.52 V/dec，載流子遷移率 (Mobility) 最大為34.7 cm2·V-1·S-1。 另外，在二硒化鈀元件的熱電性能測量上，得到的最大席貝克係數約爲655 µV/K，與理論值十分接近，並觀察到席貝克值與電晶體場效應有關聯性。當閘極偏壓設定在臨界電壓附近時，席貝克係數到達峰值，而當閘極偏壓小於臨界電壓時，通道關閉沒有熱電效應。最後計算了二硒化鈀的熱電功率因子(Power Factor, PF)，通過調節閘極偏壓觀察熱電功率因子隨場效應的變化，並對比相應的材料層數，發現最大熱電功率因子為0.26 mW/m·K2，材料厚度為12層，證明二硒化鈀

是極具潛力的熱電材料。
