林下（陰地）植物長期生活在較少陽光的地方，卻依然欣欣向榮。因此，我們針對林下植物的葉綠體囊膜電池做討論，希望可以找出發電效率更高的葉綠體囊膜電池。

我的研究是利用一些特殊的手法來探討所有情況皆會產生共點圓或共圓點。在一個由四條直線(無平行線組、無共點)所構成的圖形中，可以找到四個三角形及它們的外接圓。我知道它會共點，在此稱其為限制點。且若再添加一條直線，則可以任意的取出四條直線，分別找出它的限制點，而這些限制點又會共圓，吾稱其為限制圓。我欲證明此種情況會不斷延續下去。即是六條線時又會有限制點，七條線時又會有限制圓…。在本研究中，我利用了數學歸納法、特殊的編號方法以及「方向角」來做出此證明。由於固定的線組對應至固定的限制點或限制圓，希望能向找出其性質的方向發展。In my study, I use some skills to discuss all the situations which satisfy following conditions. The result is that concurrent circles or concyclic points will be found in every situation. In a graph consisting of four lines, conforming to conditions that any three lines won’t be parallel or intersect at one point, I can find out four triangles and their circumscribed circles. I know these circumscribed circles will be concurrent and I call the point at which all the circles meet “restricted point”. If another line is additionally added in the graph, I can discover that restricted points determined by any four lines in the graph will be concyclic. I call the circle “restricted circle”. What I want to prove is that the above situation will go on. In other words, restricted points will exist when I have six lines, and restricted circles will exist when I have seven lines and so on. In my study, I used Principal of Mathematical Induction, special ways of numbering points and circles, and “orientated angle” to prove my hypothesis. Because of particular line groups corresponding with particular restricted points or restricted circles, the further work I want to attain is to find the relation of them.

為了測量測量乒乓球彈跳，設計了測量的方法，基本構想是將乒乓球在木板上的彈跳（接觸與離開）視為開關的ON與OFF，將訊號產生器所產生的電訊號接到乒乓球上，木板接到電腦錄音輸入端，當乒乓球與木板接觸時，形成通路訊號進入電腦，由錄音程式加以記錄，反之為斷路，記錄停止。但如何將乒乓球、木板由不能導電的絕緣體轉換成可以導電的導體，而又不能影響乒乓球原本彈跳性質？想出了用2B鉛筆（含石墨）將乒乓球、木板塗黑轉變為導體的方法，解決這個問題後，成功測量出以下乒乓球彈跳時各項的記錄：1.彈跳次數2.碰撞作用力3.接觸時間4.飛行時間。最後以力感測器直接測量碰撞作用力，來驗正此實驗正確性。

The applications of digital image are rapidly growing with the developments in computer technology. This enforces digital image industry to produce devices with better quality. Despite the today’s advanced level of technology, it is known that input and output devices somewhat cause color distortions. International Color Consortium suggests that we can use ICC profile to overcome the problem mentioned above. But the related hardwares and softwares are too expensive for the general users. In this study, we base on the ICC profile’s mechanism to develop a color calibration method for low cost image acquisitions. From the theoretical and experimental results, it can be demonstrated that our method appears satisfactory.數位影像的應用隨著電腦資訊科技的快速成長而蓬勃發展，這也促使著數位影像工業的相關產品漸漸地普及與廣泛地使用，時至今日，雖然有著很好的製造技術，但是任何數位影像設備均無法完美無失真地將原有的色彩呈現出來或紀錄下來，或多或少都有色彩偏差的存在，尤其在價格越低廉的設備上更為明顯。雖然可以依據國際色彩協會的建議，使用每項設備的專屬色彩描述檔來克服色差的缺點，但是用來產生色彩描述檔的相關軟硬體均價格昂貴，實非一般使用者所能承受的負擔，本篇研究以色彩描述檔的色彩轉換機制為基礎，發展出針對廉價取像設備的色彩校正程序，無論從理論數據上的探討以及實際影像上的測試看來，我們的校正方法確實有效，讓原有的色彩能精準地重現。

這是一系列關於水蒸氣冷凝為極細微小水珠的長程實驗。其中可以分為下列三個階段：第一階段是基礎實驗。將水氣導入至潔淨的光滑表面上(蓋玻片)，觀察水珠冷凝的機制。第二階段是在外加磁場及電場作用下，將水氣導入至潔淨的光滑表面（蓋玻片），觀察水珠冷凝的機制。這部分的實驗推翻了一般「水分子是電中性，在電場或磁場中不受影響 」的刻板觀念！實驗所呈現出來的冷凝水珠，不但有明確的自我組成模式( Self assembly pattern)。並且發現：電場會增速凝結水珠的成長(Aggregation)，而磁場則會抑制凝結水珠的成長。第三階段是將水蒸氣導引至超聲波的環境中：我們先將超聲波訊號產生器(變頻、定頻)面向於載台旁，再讓水氣導入至潔淨的光滑表面上(蓋玻片)，觀察冷凝水珠的機制。當使用固定頻率超聲波波源，我們發現：在超聲波場中水珠的成長會受到抑制，且成長速率會隨著頻率的升高而逐漸減小。第一階段與第二階段的實驗結果與討論已分別發表於2004 年及2005 年的台灣國際科學展覽報告中，本作品將詳述第三階段。 This experiment explores the basic nature of the condensation of water vapor into droplets on the surfaces of cover glasses. This condensation occurs because of the difference in temperature between the water vapor and the cover glass. The condensation process is observed under a microscope. The growth of the droplets can be described as: nucleation, aggregation (piling up) and coalescence. The growth is irrelevant to surfaces or environments. It is found that the temperature difference of moist air over the cover glass do not affect the nucleation size of the droplets in simple plain surroundings; while the change of flow rate does. In general, the coalescence is speeded up at higher temperatures. Furthermore, the effects of electric fields 、magnetic fields and ultrasonic waves are also studied. It can be observed that the size of water droplets become smaller and grow more uniformly under magnetic fields or imposed ultrasonic waves; also, the aggregation rate is decreased by imposed magnetic fields or ultrasonic waves, and it is increased by imposed electric fields. These effects of magnetic fields 、electric fields and imposed ultrasonic waves might be related to the flow conditions and the vibration of surrounding air in the system. This experiment provides the first step in the understanding of the formation of water droplets and their self assembly mechanism in different environment.

本研究主要分析氣象因子對於灰面鵟鷹春季過境八卦山區之影響。分析1994年至2004年灰面鵟鷹遷徙資料發現彰化八卦山區之微氣象與灰面鵟鷹族群遷徙波動性具有顯著的相關性，其中以日平均氣壓、日平均相對濕度、日平均風速及日平均風向等氣象因子分別對起鷹、落鷹之族群數影響最為明顯。而其遷徙週期之動態變化，明顯地集中於約16日內完成主要族群之遷移。不論是同一年度內之高峰期變化，或是高峰期與日期契合之相關性，顯示氣象因子為其遷徙影響的重要因子。然而，從各年度間的遷徙高峰期間的相關性分析結果得知，目前11年過境調查紀錄，應該無明顯的規律性動態變化模式，考量其他對於遷徙過程可能具有影響的因子，應有其他的環境或生物因素影響遷徙期間族群的波動性及週期性。對於建立其遷徙模式而言，可能需要更多且更詳盡的遷徙紀錄，以及配合遷徙過程的各過境點的氣象或其他因素合併分析，方能獲得更為明確的結果。The main purpose of this study is to find the effects of the meteorological factors on the dynamics of the migrating population observed at the Pakuashan area in spring for the gray faced buzzard. The migrating population dynamics observed at the Pakuashan area correlated significantly with the local meteorological factors noted from 1994 to 2004. The daily average atmospheric pressure, average relative humidity, average wind speed and wind direction had significant impact on the soaring and landing populations of the gray faced buzzard. Obviously the annual migrating dynamics observed at the study site was accomplished within 16 days. In addition, the similar variation pattern of the peak migrating populations in the same year as well as the consistency of the date of the peak population observed annually supports the hypothesis that the local meteorological factors have a great impact on the migrating behavior of the populations. However, the correlation analysis of the peak migrating populations among years indicated that little cyclic migrating pattern was found in the past 11 years’ observation records. Other biotic or abiotic factors might have influence on the periodicity and fluctuation of the migrating populations. In order to establish a precise population model to describe the migrating behavior of the gray faced buzzard, detailed records of the migration process and the analyses of the relationships among the meteorological data as well as other factors and the bird populations observed should be gathered and performed.

在一個有障礙的平面上，給三個定點，我們探討連接此三點的最佳網絡。我們討論了諸如直線、射線、線段、圓、網格狀、三角形……等類的障礙，當網絡每穿越障礙一次，就必須付出代價，例如「拖延5 分鐘」。所以，設網絡穿越障礙的次數為y ，則網絡除了原本的總長度之外，還額外加入y 倍某固定數值的損耗。我們以費瑪點的各種性質及三角形不等式等方法為工具，就不同的穿越障礙次數綜合比較，而找出最佳網絡。在某些情況下，最佳網絡不是以費瑪點來連接三點，而是在障礙(如：直線)上找出符合某種與餘弦值相關特殊性質的點，以該點來連接三點，而此網絡可用GSP 軟體相當精確地作出。另外，我們也探討在考慮障礙造成損耗的情況下，兩點間的「實際距離」為何。 最後，我們考慮「混合障礙」問題。在此類問題中，除了前面所討論的障礙，還另加了如同「河流」的兩平行直線間區域之障礙，在這種障礙區域中，網絡的長度要乘以數倍來計算。我們發現，此類問題的最佳網絡也可用特定的正弦條件配合GSP 而相當精確地作出來。;Considering various kinds of obstacles in a plane, such as a line, a segment, a ray, a circle, a triangle or chessboard grids, which function like a red light, we research into the problem of finding the optimal network connecting three given points A, B, C in the plane amidst obstacles described above. Each time when the network crosses an obstacle, it will cause losses, such as five minute’s delay or a loss of one hundred dollars. Taking advantage of Fermat points, some basic inequalities concerning triangles and some special qualities about sine or cosine functions, we obtain the optimal networks in different situations. Besides, we consider what the “real distance” between two points is when there are obstacles in a plane. We also put another obstacle, including a line and a weighted region between two parallel lines, into consideration. In the region, like a river or a muddy ground in real life, the length of the network should be multiplied by a fixed time. Furthermore, we can use GSP to make the networks very accurately.

「風笛」是台灣原住民鄒族的信號用具及祈雨法器，由一條繩子綁一支竹片構成。轉動風笛時，竹片會繞繩子自轉並拍打空氣而發出聲音，並有上下飛舞的現象。風笛產生聲音的原因，為竹片拍打空氣而造成的渦流共振現象；又由於繩子扭力大小及方向改變，使風笛的音調忽高忽低、響度忽大忽小、且竹片會在兩個平面上公轉，而有週期性變化。施力使風笛公轉轉速加快時，竹片自轉速率也變快，使其音調愈高、響度愈大；而繩愈短、愈粗時，竹片的公轉週期將愈短。The wind whistler was once used by Tsou aborigines as a tool for message transfer. It is composed of a string and a bamboo flapper. When swung around, the flapper spins, beats the air, and makes sounds. Moreover, the flapper flies up and down during the revolution. The spinning flapper beats the air, causes the vortex resonance phenomenon, and thus produces sound. As the twist torque and direction change, there is periodical variation in the sound volume, sound pitch, and the movement of the flapper, which orbits up and down at two planes. If given force to speed up its revolution, the flapper，s spinning frequency also increases, which makes the sound pitch higher and the sound volume greater. Besides, when the string is shorter or thicker, the flapper，s revolution period will be shorter.
