葉綠素為植物體內進行光合作用關鍵物質，在能源領域內也有不少的應用。葉綠素是光合作用的鑰匙，葉綠素能夠累積光的能量並放出激發態電子，利用激發態電子的能量進行一連串複雜的反應，本研究的理論就建立在光合作用上，利用葉綠素吸收光能轉為電能的特性開發新型光電池。光電池使用金屬或非金屬材料，照光後能產生電流之材料作為發電材料。電池的製作過程非常簡單，實驗發電材料葉綠素也很容易取得，完全沒有汙染環境的疑慮，是非常乾淨的綠色能源。另外也探討葉綠素濃度對於發電效能的影響。研究使用的裝置是由兩片玻璃與矽膠片組裝而成的電池，在電池中間加入葉綠素與電解液。藉由改變電解液與有無光照來探討葉綠素在該電池中的氧化還原作用是否有明顯的變化，並推出化學反應式。結果顯示在葉綠素與電解液的配合下能夠建立出一套循環產電系統。

台灣西海岸的河川，常飽受嚴重的水污染，其中最嚴重者莫過於重金屬離子所造成的危害了。所以，本作品即探究：從了解【電解水的氧化還原反應】到設計【小型多重兩極分流電解槽】上，希望藉此設計能給相關單位參考，以為農田引水灌溉及養殖水域做把關的工作。最後並對長期以來校內涉及電解、電鍍…等含重金屬離子的實驗做徹底的減廢設計，以排出無污染性的廢水。;Rivers along the west coast of Taiwan have been seriously polluted for a long time, the most hazardous one of which has been caused by heavy metal ion. As such, this article aims at how to discharge a pollution-free wastewater by understanding first from the oxidation- reduction reaction of electrolytic water to design of a miniature multiple bipolarity divided-flow electrolyser. It is hoped that this design would provide related government regulatory agencies with adequate information so that they may be capable of doing a responsible pollution-prevention job in water irrigation for farming land and water for marine farming as well. Finally, the author may further add that this design has been through constant laboratory tests involving electrolysis and electroplating of heavy metal ion in the hope that a perfect design to eradicate wastewater can be produced so as to discharge pollution-free waste water.

本研究旨在探討環境濕度、聲音分貝大小及PM2.5濃度是否會影響植物的蒸散作用。已知植物蒸散作用旺盛與否與植物葉面上、下表皮(溫度差異)大小有關。本研究除了利用顯微測量技術測量茉莉氣孔的大小之外，並利用自製物聯網溫度分貝儀進行茉莉與番茄葉片表面溫濕度、聲音分貝大小及PM2.5濃度約六個月之數據收集。本研究將已搜集之資料經分析後，獲得以下結論：(1)當聲音(分貝大小)達到特定範圍時，植物葉面上、下表皮溫度差異會變大；(2)當環境濕度變高，植物會因氣孔變小，溫度差異變小；(3)環境中PM2.5的濃度和植物的蒸散作用間則無關聯性。根據結論(1)，本研究結果推論植物有小小的耳朵。

本研究使用鋁板探究快速解凍法，利用熱傳導，嘗試排水導流和增加接觸面積；利用熱對流，使板面立體或加裝風扇，增加空氣對流，解凍速度再升級，自製出第一代魔力解凍板，並且改良研發第二代魔力解凍板成為綠色環保產品。我們發現： 一、鋁板厚度達2mm時，解凍速度可增加5~10倍，但持續加厚解凍效率趨緩。 二、「孔洞導流鋁板」兼具排水與接觸面積的優點，因此解凍速度優於其他鋁板。 三、增加冰塊與鋁板的接觸面積可以加速解凍，最佳解凍板組合為上層4mm下層2mm，解凍速度較單層快2.3倍。 四、第二代解凍板使用鋁扁管與第一代解凍板使用風扇之解凍效果相當。 五、第二代解凍板解凍豬排的速度優於市售解凍板，較自然解凍快11.5倍，低於平均市售價格達1707元。

In out wOItwe have fabricated rap1d positioning sine bar by combining micrometer and sine bar.The purposes ofthis research are producing dimensions accurately and rapidly.Thus,it won't have errors when workp1eces are mached and measured. 正弦桿是測量角度的精密量具，基本上，正弦桿需跟塊規組合使用，再利用Ｈ＝Ｌ Ｓｉｎθ 算出需組合之高度，在算出需用何種尺寸之塊規需用幾塊，但如果遇到多種不同高度時，則需要更換不同尺寸之塊規，塊規在每次使用時都需清潔乾淨，十分的不方便，在此我們利用測微器，與正弦桿結合，捨去塊規，研製出快速定位正弦桿。此一設計主要包含有原本的正弦桿，一支測微器，結合成新的正弦桿，本正弦桿主要的特性是，在每一種高度算出後，即可利用正弦桿上的測微器直接旋轉到需要之高 度，且轉到需要之高度後可將測微器固定讓測微器不再旋轉，且兩者是一體的，不會出現測量或是加工時，正弦桿移動之現象，使用中也不會去觸摸到測微器之測頭而產生了熱脹冷縮之誤差發生，達到快速定位之需求。

磁浮隔空旋轉器是由一個旋轉軸和底座構成，利用兩者間相互排斥的磁力， 產生隔空漂浮的效果。本研究首先對旋轉軸的結構加以分析，並設計啟動裝置， 探討啟動電壓、旋轉軸重量及底座磁力等因素對漂浮轉動的影響。 我們分析維持旋轉平衡的各種作用力，並探討旋轉軸重心位置與摩擦力的關 係，以驗證我們的分析結果。此外，我們也利用自行設計的啟動裝置，提供穩定 的初始轉速，探討旋轉軸重心位置不同時，持續轉動時間的變化，進一步驗證所 做的分析。 為了瞭解磁場在旋轉軸漂浮過程中發生的變化，我們設計了支架把空間座標 化，再以高斯計測量出各點的磁場，獲得各平面的磁場強度分佈圖。配合磁力線 分佈圖與所測得的磁場強度分佈圖，我們以一個嶄新的分析模式，將抽象的磁場 概念具體化，使我們對旋轉軸放置前後及磁力與重力平衡時的磁場變化，更深入 的了解，同時也發現磁場強度會隨距離的增加而減弱。 最後我們在旋轉器上裝置感應線圈，經由旋轉實驗測得感應電壓的存在，證 明旋轉器轉動時，磁場會產生變化。 經由對磁浮隔空旋轉器的探討，我們得以了解它的漂浮原理、磁力與摩擦力 間的平衡關係，以及旋轉前後磁場變化。The Magnetic Floating Spinner(MFS) is composed of one spinner with a magnetic base. The floating effect of the spinner is caused by the interaction between the two opposite magnetic fields. We first analyzed the detail structure of the MFS, and then designed a starter to rotate it. Later, we studied the effect of starting electric potential, the weight of the spinner and the magnetic force of the base on the floating movement. We presented an explanation for the forces that maintained the floating of the spinner and, to support that, we studied the friction force with the position change of the spinner gravity centre. We also used the starter designed by us to provide a stable initial rotating force and analyzed the relationship between the change of gravity centre position and the duration of rotation. In order to understand the magnetic field change during floating movement, we designed a spatial frame to coordinate the spinner that floated above the base. We measured the surrounding magnetic force with the Goth’s apparatus and conducted a magnetic force distribution diagram. According to this diagram and the line of magnetic force, we therefore provide a brand new analysis model , which bring the abstract concepts of the magnetic field into a concrete theory. This research not only brings us to understand the magnetic field change of the spinner before and after its placement over the base and the balance between the magnetic and the gravity force, but also reveals that the magnetic force will wane with the increase of distance. Finally, we placed an induction coil by the spinner to detect a voltage change during spinner movement. This is an evidence that the magnetic field will change during the spinner movement. Through the study of MFS, we can now understand why it floats, the balance between magnetic and friction force, and the change of the magnetic force before and after the spinner movement. MFS = Magnetic Floating Spinner

單淘汰賽是一種失敗一次即遭淘汰的賽制；在此假定每位選手都有一相對應的能力數值，本文主要探討在均高的單淘汰賽程表之下，若賽程安排完全依照種子安排原則(亦即最強的選手對最弱的選手、次強隊次弱….)，則對於能力越強的選手越有保障，直觀上而言能力最強的選手應有最大的奪冠機率，探討此種賽程安排是否滿足能力較強的選手有較大的勝率？因發現在某些特殊的選手能力數值分佈之下會發生次強選手勝率大於最強選手的情況，令A、B代表最強與次強選手，P(A)、P(B)代表A、B奪冠的機率，故擬定P(B)/ P(A)為參考依據，尋求P(B)/ P(A)的最大值發生處作為最極端的狀況。發現四位選手的情況下，P(B) / P(A)最大值 = 1；八位選手的情況下，P(B) / P(A)最大值=(196+98) / 343=1.0938，當選手數為2n時，P(B)/ P(A)最大值隨n的增加而遞增。 Knockout Tournament is a highly competitive system in which any player losing a game can no longer play in the tournament. Here we suppose that every player has a numerical value that corresponds to his ability. We consider a totally-seeded knockout tournament with 2n players where in the first round, the strongest player matches the weakest player, the second strongest player matches the second weakest player, and so on. We examine whether a stronger player always has a greater probability of winning the tournament. The answer is in the affirmative for n = 2. For a tournament with eight players(n = 3), the situation is much more complicated. In certain cases, the second strongest player has the greatest probability of winning the tournament. Specifically, let A and B denote the strongest and second strongest players, P(A) and P(B) their respective probability of winning the tournament. We find that the maximum value of P(B)/P(A)equals (196+98) / 343 = 1.0938. For n > 3, we have not obtained the maximum value of P(B) / P(A) . However, it can be readily seen that the maximum value of P(B) / P(A) is non-decreasing as n increases.

The heavy rain fall brought by Typhoon Mindulle in 2004 caused debris flows in the mountains of Taiwan. The most serious debris flows took place in the areas along the East-West Expressway. The area from Mt. Li to Tien Leng, namely, from the upper course to the middle course of River Da Chia. There was plenty of debris flowing to the courses of the rivers from the hot spring area in Ku Kuan to the starting place of East-West Expressway, Tien Leng. This situation caused the sedimentation of the river courses. According to the data issued by The Soil and Water Conservation Bureau of the R.O.C, on July 2nd debris flows erupted in the First and the Second branches of the river in Sung Ho Village and caused 1 death and 2 injuries, besides, the disaster destroyed 8 major roads causing transportation breakdown. On August 24th, the Typhoon Aere caused the heavy flow of the river which destroyed Po I Elementary School and Chun Chin Bridge. The researchers employed research reviews and field investigations as the research methodology with the research scope of Sung HoVillage in middle Taiwan and disaster of debris flow. The First and the Second branches of Sung Ho River belong to the category of high potentiality of danger of debris flows. The Chichi Earthquake had accumulated sufficient sedimentation of soil and stone. 2004 年敏督利颱風豐沛的雨量，引起台灣山區發生土石流，中橫公路沿線尤其嚴重。從 大甲溪上游的梨山到中游的天冷都有災情；谷關溫泉區至新中橫起點的天冷，大量土石，流 入溪中，造成河道淤積。據水土保持局的資料顯示，7 月2 日松鶴一、二溪爆發土石流，傷 亡各1 人，2 人失蹤，對外聯絡道路台8 省道崩塌中斷。8 月24 日艾莉颱風來襲，溪水暴漲， 沖毀博愛國小、長青橋及民房7 戶【1】。 本文以松鶴為試區，土石流災害為對象，使用文獻探討及現場調查的方法，進行研究。 結果顯示，松鶴一、二溪，均屬於土石流高危險潛勢溪流；肇因於九二一地震的崩塌地，提 供充足的土石堆積物。

一. 此研究是探討物體自由搖擺的現象，單擺和複擺是在物理學上常見的擺動現象，都是一種固定支點的擺動現象，尤其複擺運動時，擺動物體受轉動慣性影響而造成支點的受力，為一種拘束的第一向後運動現象。而本研究在探討多自由度自由支點的單一方向度之擺動現象。二. 本實驗從這幾種方向分別探討1. 扇形體在平面上之擺動2. 平板在圓弧面上之擺動3. 扇形體在圓弧曲面上之擺動三. 經我們實驗研究結果發現，在地球重力場中沒有固定支點的搖擺現象，是受到下列幾種因素影響1. 搖擺形體的形狀，其質量慣性矩的影響。2. 擺動物體與接觸路徑的相互影響。3. 擺動質量對擺動的頻率影響很小。This research explores the phenomena of swinging objects--- simple pendulum andcompound pendulum, which are constantly observed in physics. The inertial moment of the swing produces pressure to fixed points of support on which the swings occur, especially in compound pendulum, which are classified as restricted single freedom. The study provided here explores the phenomena of the frequency of unfixed supporting points. The exploration of this research develops experimentally as follows: a. fan shaped objects swinging on the plane surface b. flats swinging on the arced surface c. fan shaped objects swinging on the are-curved surface An impressive conclusion that there is no swinging phenomenon of fixed supporting points in gravity field on earth is achieved from the above experiments. A number of factors influence the phenomena of swings: a. the shapes of swinging objects and the influence of mass inertial moment b. the interaction between swinging objects and interfacing paths c. little influence from swinging mass to the swinging frequency

本研究主要探討水滴在高溫鋸齒面上之爬坡現象。實驗中發現在高達四百度的鋸齒面上能形成懸浮水滴，且水滴可持續一段時間而不會立即蒸發，在水平之鋸齒面沿特定方向移動，特別的是，水滴甚至沿著傾斜之鋸齒面向上運動。首先，水滴因受熱在周圍形成一層蒸氣層，阻隔熱的傳遞，使其不會立即蒸發。實驗中改變鋸齒齒廓之兩斜邊的比例，可以驅動水滴往長斜邊所面對的方向運動。進一步實驗顯示，水滴內部的流動趨勢分別為：水滴前端呈順時針方向流動，而水滴後端則呈逆時針方向流動。此外，爬坡中的水滴，其後半部具有較高之蒸發速率，經由設計一個類比的實驗，我們發現，在高溫金屬平面上，透過其平面上的一個凹槽，可以控制水滴前後部位蒸發速率的差異性，也造成水滴向上爬坡的結果。由實驗結果證明，蒸氣壓力與氣體運動對水滴造成的摩擦力為驅動水滴爬坡的力量來源。
