產電生氫伏打電池

在一次意外的發現中,我觀察到以鱷魚夾夾住的鎂帶在海水中竟然不斷的冒出氣泡,引起了我一探究竟的興趣。經由一系列的探索和實驗,我驗證了此種奇特電化學行為的反應機制,並且藉著此種機制,我嘗試尋找可以產生最大電流、電壓的伏打電池組合,以便製出一個又產電、又生氫的新式伏打電池,一方面可作為直流電的電源,另一方面產生的氫氣又可作為燃料電池的燃料來源。 In one accidental discovery, I’ve observed that there were continuously bubbles coming out when a magnesium stripe was attached by the metal clip in the sea water. This incident aroused my curiosity to find out the reason. Through a series of searching and experiments, I have proved the mechanic reaction of this spectacular electronic chemical behavior. Then I tried to search for a combination which can produce the greatest electronic current and voltage in order to produce a new type of voltage battery that can produce electricity and hydrogen. In one way, it can be the source of producing the direct-current. On the other way, the hydrogen it produced can also be the source of a fuel battery.

曲桿「弦」臂-λ/4的玄機

靈光乍現:弦的震盪由直到彎,從單懸到雙懸迴盪不已,共振駐波顯現半波長的微妙變化。故佈疑陣:曲弦振盪、共振頻率、弦上張力、半駐波長,玄機重重。 高潮迭起:推翻同一弦上所受張力相同,得知曲弦曲度不同所受張力亦不等的真相。 明天過後:重現曲弦程度,知彈性係數迴旋,將曲弦駐波性質變化摸透透。 ;Inspirations: Vibrating the string of thing bar from longittudinal to transverse; from both arm to single arm; from the waves of the string to the mystery ofλ/4. Battle: Resonance frequency, string tension force, half stationary wave, questions flying everywhere. Revolution: Overturn the theory that the tension force on the same string equalizes everywhere by measuring the length of eachλ/2 ; proof that the tension force enlarges from the top of the string to the end because of the gravity of the string ; Calculate the constant of the difference between the length of the incomplete wave on the end andλ/4 / the last completeλ/2. Proof that the constant is decided by the thickness of the string rather than the length of the string ; Finding the fact that the number of completeλ/2 on the same string equals no matter where the vibrating spot is.

旗海飄揚—旗面波之探討

無意間在某大學的科學討論版中,發現有人提問了一個關於旗子的問題,但遲遲無人回應。 \r 經過仔細思考這個問題後,想起許多旗幟在空中隨風飄揚的景象,那些旗子似乎有著一定的律動,而這個律動中,風扮演著一個十分重要的角色,不禁使我感到好奇:「風與旗子的擺動究竟有什麼關係?」,恰好有研究的機會,於是就以『旗海飄揚------旗面波之探討』為題目,展開了一系列的研究。

高階電腦數位影像之研發

快門,捕捉最原始的感動;科技,創造最完美的呈現。當攝影遇上科學,成就了本研究的主題──高階電腦數位影像之研發。在我的研究過程中困難重重,從外景攝影、後製研究、影像創作到本研究撰寫完工,一切由我個人獨力進行,經歷了多次失敗,仍堅持的完成這重大的研究突破。 相信多數人會使用相機,但是對數位攝影這領域卻不甚了解,更別談藝術與科學的結合。因此希望本科展研究將會成為未來科技數位電腦的主軸,強調科技、即時、便利、環保、生活及教育的科學推廣,以實用並超越新世紀的數位領域,讓所有電腦愛好者,都可以輕鬆的應用此高階的數位暗房後製。讓電腦科技不只是零與一的組合,而是心靈與世界的互動! ;Camera shutter captures the most original affection; technology creates the most perfect display. High-level digital image—when photography meets technology—is the theme of this research. However, in the process of the research, I have encountered many problems—from outdoor scene shot, production research, image creation to report writing—I did them individually and had undergone many failures, but I still insisted on finishing this big research breakthrough. I believe that many people can use the camera, but didn’t understand anything about the field of digital photography, let alone the combination of art and technology. I hope this technology development research would become the main perch of digital technology in the future—emphasizing technology ,instantaneous,convenience,environmentalprotection, livelihood, and popularize technology education—to use and go beyond the new age of digital field and to make computer lovers apply high-level darkroom production easily. Making computer technology not just combinations of zeros and ones, but the interaction between life and the world.

利用電化學探討土壤奈米粒子對重金屬的吸附

由於工商科技的發展帶給環境負面的影響日漸嚴重,其中尤以重金屬對台灣環境的影響較為顯著,故探討能移除排放廢水中的重金屬之有效天然資材有其重要性。以台灣天然存在之大地資源土壤中的奈米粒子來進行對汞、鎘的吸附,試驗結果得知,台灣三種代表性土類土壤中的奈米粒子確實能有效地吸附汞離子和鎘離子,且其中以對汞的吸附要大於對鎘的吸附。屬於砂頁岩沖積土的奈米粒子對汞、鎘的吸附最大,其次是黏板岩沖積土的奈米粒子,而最小的則是屬於台灣紅壤的奈米粒子。以上結果經由電化學方波伏安法的測定、電導度計法的測定與發芽率試驗結果都有相同的趨勢,顯示土壤奈米粒子可用來當作移除汞、鎘等重金屬的天然資材。 ;Effects of heavy metals are significant in Taiwanese environment due to serious impact of environment was made by development of industry and commerce. Therefore, study of removing heavy metals from waste water by natural materials is important. We need nanoparticles of natural soils to study the adsorption of mercury and cadmium ions. The experimental results indicated nanoparticles of three represent soil groups in Taiwan could adsorb effectively mercury and cadmium ions, and the adsorption of mercury ion was more than that of cadmium ion. The nanoparticles of sandstone-shale alluvial soil had largest adsorption for mercury and cadmium ions, and next for that of slate alluvial soil. The nanoparticles of red soil had smallest adsorption. All results were proved by voltammetry of electrochemistry, conductivity method and germinant percentage of vegetable seed. That obviously revealed soil nanoparticles could remove effectively mercury and cadmium ions.

不偏不倚--奈米級修準方法與敏感度評估之研究

Positive –A Study on a Nanoscale Revision Method and Sensitivity Evaluation This paper took a pyramid and a fixed point as the reference level. It was the intention of our team to establish and prove a new hardness value revising method that is to be used in the deflection of indentation of nano indentor. Such new method was named Material Surface Nanoscale Hardness Revision Method with which we re-measured various materials and error sensitivity of hardness values. We obtained the following conclusions:(1). This paper revision modification method have a highly precision. (2). When the round tip or plane tip was closed to ideal indentor tip, the contact areas during indentation process were close, not demonstrating significant difference. (3). The indentation triangle created when loading effort P was similar with the one left on the sample material when unloading the effort; thus, even though the sink-in and pile up effects due to the mechanical properties of sample material caused the differentiation of side lengths and two indentation areas, the angles of two indentation areas was the same. (4). When the effort was loaded by the tip onto the sample material, if the tip had a certain deflection ψ or rotation ω, the indentation triangle left on the sample material was still significant. (5). In the observation of the indentation triangle left on the sample material, when the triangle cannot become a regular triangle, it meant that there is a deflection or rotation happening to the tip and a further revision of the deflected angle ψ or rotated angle ω is required. (6). The hardness value revision method under indentation deflection situation had the best effect on the projected area revision; the second was on the indentation volume revision and than on the indentation contact area revision. (7). The hardness error sensitivity of hardness value revision method under indentation deflection situation had the best effect on the projected area; the second was on the contact area and than on the indentation volume revision. (8). The method proposed by this study was proved by the silica and aluminum single crystal indentation results and is thus able to be applied to the engineering in the nanoscale measurement of metal materials to obtain more precise data.不偏不倚-奈米級修準方法與敏感度評估之研究在這篇研究報告中,以一個三角錐和一個定點為基準,本團隊建立並證明一個新的在奈米硬度測試儀壓痕偏斜情況下,硬度值的修正方法,取名材料表面奈米硬度修正方法。在新的材料表面奈米硬度修正方法下,重新檢測各種材料及硬度誤差敏感度,得到許多好的結論:(1)本研究之修準方法具有高度精確性。(2)利用圓球尖端或平面尖端的方法近似理想壓頭時其壓痕過程中之接 觸面積相近,並無明顯差異。(3)作用力P 施加(Loading)時之壓痕三角形與卸載時(unloading)殘留於測試材料上之壓痕三角形係屬於相似形;因此,即使各該三角形之邊長因為該測試材料本身的機械性質所產生的滲入(sink-in)與堆放(pile-up)的效應而造成作用力施加與卸載時,壓痕面積上的差異。不過,該兩壓痕面積的角度卻是一致的。(4)當該作用力隨著該壓頭施加於測試材料時,若該壓頭產生某一程度的偏斜ψ 或旋轉ω 時,該殘留於測試材料上之壓痕三角形仍然具有代表性。(5)藉由觀察該殘留於測試材料上之壓痕三角形,當該三角形無法成為一正三角形時,其係表示壓頭已產生偏斜或旋轉的之情況,需要進一步對該偏斜角度ψ 或旋轉角度ω 進行修正。(6)在壓痕偏斜情況下硬度值的修正方法以投影面積修正為最佳,其次是壓痕體積再其次是壓痕接觸面積方法作修正。(7)在壓痕偏斜情況下硬度值修正方法的硬度誤差敏感度則以投影面積為最佳,其次是接觸面積再其次是壓痕體積修正方法。(8)本研究提出之修正方法經由矽、鋁單晶壓痕結果驗證,足以說明適用於工程學上金屬材料進行奈米壓痕硬度檢測時更精確的數據獲得。
