簡單的說，我們是要在三角形、四邊形或凸多邊形的內部找一點P，使得P 連接到各邊上給定的點後，即可等分面積。概念如下圖： 不過由於多邊形難度較高，因此我們從三角形或四邊形開始。而邊上找的點則先由中點開始。

棘海馬 (Hippocampus spinosissimus) 經飼養觀察首次發現排放標示物行為。標示物標記偏好的棲枝，為海洋珊瑚礁魚類中類似的標示的新發現行為。觀察棘海馬會由泄殖腔孔排放一種白色的標示物，其成分鏡檢證明與棘海馬的排遺無關，且其更容易在水中漂流並黏附在棲枝上。棘海馬利用嗅覺幫助尋找含標示物的棲枝 (卡方值 : 24.183, P<0.001)。棘海馬不會傾向攀附有其他海馬標示物的棲枝，無論相同性別間或異性間，均未達顯著水準。標示物中有效成分為水溶性物質，其效能在室溫下可維持約7天，且冷藏可延長其標示效能。經由解剖觀察，證實標示物的分泌器官為泄殖腔中的生殖腺，但生殖腺切片中證明標示物分泌與棘海馬繁殖無關。

By saving water you are saving lives including yours. All of us know that water is an invaluable and priceless gift. We can’t dispense it. The consumption of water differentiate from one country to another, we may use over quantities of water, in other countries people are thirsty living under the limits of poverty .It’s very important for agriculture, industry even human animals and plants can’t live without water. But people are careless, they consume a huge quantities of water in shower, washing car, gardening…. So that we thought to make this brilliant project F.W.S (frugal water system). This system is connected with you mobile phone by an application that shows you your water consuming and makes you control it. It record in every minute your consumption. This control system helps us to preserve water for the future generation. Besides, it tells you the price that you will pay and warns you if you pass the quantity of water that you should consume in a defined period. So you can also save your water bill. So we have to make this project works to let every person know that he is doing squandering water. With this system we can save planet resources of water. Finally, the water is as precious as our lives and with frugal water system, we will be able to monitor and control our water consumption. Also be alerted in the event of a leak or flooding. This project helps us to preserve water, reduce and avoid over-consumption. So we have to stand together against water squandering by making this project works.

給定任意一個三角形，三個內角的三等分線兩兩交於三點，此三點形成一個等邊三角形，稱為莫利三角形(First Morley Triangle)。本作品從莫利三角形所牽涉到的三個特殊點開始： First Morley Center (FMC)：即莫利三角形的重心。 Second Morley Center：即原三角形與莫利三角形對應頂點間的連線的交點。 Third Morley Center：即原三角形與First Morley Adjunct Triangle對應頂點間的連線的交點。 我們巧妙證明了這三個特殊點共線，並進一步推廣到所有與原三角形的三等分線相關的18個正三角形(ΔDqrErpFpq) 。我們發現這些正三角形都存在對原三角形的Morley Line。除此之外，本作品最重要的成果是證明了： 當p+q+r=0 (mod 3)，p-1 q-1 r-1 -FMC在pqr -Morley Line上； 當p+q+r=2 (mod 3)，p+1 q+1 r+1 -FMC在pqr -Morley Line上； 並由此建構出在這18個正三角形中的三元組(triad)關係。

高一時，某次交理化作業─繪製電力線與磁力線圖。因而對此種不可見之力線的產生好奇，由於徒手繪製難以精確，乃構思如何得藉電腦之協助，具體而精確地描繪之，並將之落實於自然現象之解釋。

新世紀的疾病「癌症」在國內外十大死因中居高不下，而目前的冶療方法效果不顯著且常造成人體其它組織的傷害，這是個棘手問題，人們住往聞之色變；若是能找到種方法，能有效殺死癌細胞而不對正常細胞造成傷害，將十分有益於癌症的治療。 有鑑於此，我們希望藉由計畫性細胞死亡的方式，結台免疫的知識，達到上述的目的。記得在雜誌上看過，近年來發現了一個 TRAIL ﹝ TNF ( Tumor Necrosis Factor ) Related Apoptosis Inducing Ligand﹞ 分子，可以導致細胞的「計畫性死亡 ( apoptosis ，或稱作細胞凋亡 )」 ，且對於腫瘤細胞特別敏感；而「計畫性死亡」的特徵乃 (1)核皺縮 (2) DNA 斷裂 (3)細胞萎縮而不破裂，相較於另一種死亡（ Necrosis ，壞死）的死亡方式來說， Apoptosis 不會造成人體過度的發炎反應，十分符合我們的條件。 基於這些原因，我們便想培養小同的人類腫瘤細胞株，測試 TRAIL 對其造成計畫性細胞死亡的敏感度，以作為日後癌症治療研究發展的基礎；並進一步以 RT - PCR 方式定性分析各種腫瘤細胞株中 TRAIL 及TRAIL 受體的表現情形，並和人類正常細胞作一個比較，以了解人類腫瘤細胞株對於 TRAIL的敏感度和其 TRAIL及 TRAIL受體的表現之間的關係。

本文探討了特定問題的組合最佳化，所謂組合最佳化就是在共同限制及相互影響下，來求得最佳解。一個組合最佳化問題的困難，往往是由於其龐大的解空間所致。本文介紹了貓抓老鼠問題的組合最佳化，並在第一步中，以歸納法解決了一個較簡單的例子。經由我們歸納的結果，我們一共得到了五個證明，來推廣每個頂點相等通道的一般性，並且得到了四個相等通道問題所應該有的性質，之後我們又用了二個證明，推廣在完全對稱下所需的結果。第二步中，我們又用了四個證明，將問題推廣到每個頂點不相等通道的問題，並且以二個不等通道的範例，闡釋了我們所得的結果。我們所得到的結果，能有效的解決解空間不大的某些特定問題，尤其是以人工來解決問題時，提供了一個絕佳的途徑。然而當解空間變得較大且邊數不等時，即使有不錯的結果，問題也會變的非常的複雜。我們在特例探討上，解釋了即使是單純且限制了許多條件的問題，要證明一般性也不是這樣容易，所以當問題變大時，我們改以組合最佳化的最佳解逼近來取代求最佳解，而不直接求最佳解。一個好的最佳解逼近就是在可接受的時間範圍內，求得逼近最佳解。當然我們仍能以暴力法則求得最佳解，但時間範圍是我們所不能接受的，故在此不予討論。

本作品為一種架構在雲端物聯網服務上，透過手機APP雲端控制魚缸魚飼料投放的餵食器，適用於小型觀賞魚飼料的投放。我們使用聯發科技創意實驗室所製造的物聯網裝置－LinkIt ONE做為本餵食器的微電腦控制板，結合該公司所提供的MediaTek Cloud Sandbox(MCS)雲端服務，由手機的雲端APP經由無線網路雲端操控LinkIt ONE板子上的數位訊號輸出，藉由這個數位訊號啟動小型步進馬達，再經由步馬達轉動用3D繪圖軟體Sketchup繪製與3D印表機列印的魚飼料餵食器，達到由手機APP雲端控制魚飼料投放水簇箱的功能。

在吃完營養午餐後，同學清洗餐具，總會讓油膩膩的水流入水溝，對環境影響很大。因此，我希望能使用安全又有趣的方式來改善污染問題。首先觀察油、水的特性，瞭解油會浮在水面的原因，於是進行簡易分離槽的改良研究。本實驗探討在不同條件下影響油水分離的各種因素，最後製作「環保油水分離槽」，並且改進它的缺點，讓「油切」---水分離出來。改良後的「環保油水分離槽」排水速率 14.56 ml/s，油脂截留效果可達到 100 %，對降低水源污染有很大的幫助。我們也改良環保油水分離槽，製作「顏料過濾槽」和「污水過濾槽」。顏料過濾槽能讓溶液照度平均增加533.44 lux；污水過濾槽沉澱物清除率為 90.84 %，能讓大量的水再循環使用，藉以達到節約用水的目的。

EXPERIMENT 1---The effect of NaCl and Glucose Concentration on the efficiency of the cell I. Introduction Experiment on different concentrations of standard glucose solution (ranged from 0.125 M to 1.000 M) and standard sodium chloride solution (ranged from 0.250 M to 4.000 M) were done. We investigated the full concentration effect, which included both concentration of glucose solution and sodium chloride solution on the fuel cell’s output voltage, current and power. II. Procedures 1. Add 25.0 cm3 of Glucose solution of the tested concentration to the beaker representing the anode, and add 25.0 cm3 of distilled water to the beaker representing the cathode. 2. Add 50.0 cm3 of 0.250 M NaCl (aq) to both beakers representatively. 3. Fold a piece of filter paper and soak in fully into NaCl (aq) at cathode. 4. Clean and place the silver wires into the beakers representatively, and connect the air pump to the cathode. 5. Connect the cell to two multi-meters, each acting as a voltmeter and an ammeter respectively 6. Take the readings of multi-meters after 30 seconds. 7. Repeat steps 1 to 6 twice for the second and third reading of the cell. 8. Take average value among three values as the final reading of the cell. 9. Repeat steps 1 to 8 by replacing the NaCl (aq) with concentrations of 0.000 M, 0.500 M, 1.000 M, 2.000 M and 4.000 M, and the standard glucose solution with concentrations of 0.000 M, 0.125 M, 0.250 M, 0.500 M, 0.750 M and 1.000 M. III. Result of Experiment 1 When glucose concentration is increased from 0.000 M to 0.250 M, the output power increases, it is found that power generated is maximized at glucose concentrations between 0.125 M and 0.250 M. However, with further increase in glucose concentration from 0.250 M to 1.000 M, the power generated decreases. This shows that high concentration of glucose inhibits the generation of electricity, while higher concentration of sodium chloride solution can increase the output. EXPERIMENT 2---The effect of temperature on the efficiency of the cell I. Introduction In this experiment, the second effect - temperature on the fuel cell’s output voltage, current and power was investigated. In order to get a significant result, the effect of temperature on these measures with fixed 0.250 M glucose solution and sodium chloride solution concentrations varied from 0.500 M to 4.000 M had been investigated. II. Procedures 1. Add 25.0 cm3 of Glucose solution of the tested concentration (0.25 M) to the beaker representing the anode, and add 25.0 cm3 of distilled water to the beaker representing the cathode. 2. Add 50.0 cm3 of 0.500 M NaCl (aq) to both beakers representatively. 3. Fold a piece of filter paper and soak in fully into NaCl (aq) at cathode. 4. Clean and place the silver wires into the beakers respectively, and connect the air pump to the cathode. 5. Connect the cell to two multi-meters, each acting as a voltmeter and an ammeter respectively 6. Take the readings of multi-meters after 30 seconds. 7. Repeat steps 1 to 6 twice for the second and third reading of the cell. 8. Take average value among three values as the final reading of the cell. 9. Repeat steps 1 to 8 by varying the temperature from 42℃ to 32℃. 10. Repeat steps 1 to 9 by replacing the NaCl solution of 0.000 M, 1.000 M, 2.000 M, and 4.000 M respectively. III. Result of Experiment 2 The results showed a consistent trend and relationship of the effect of temperature on the output current, voltage and power of the fuel cell for 4 different concentrations of sodium chloride solution with fixed 0.25 M glucose solution. Generally, the results showed that the output power increases with temperature. EXPERIMENT 3---The effect of dialysis tubing and Nafion 117 on the efficiency of the cell I. Introduction Semi-permeable membrane separating glucose and oxygen, ensure the glucose oxidation only occurs at the anode, and preventing glucose oxidation occurs at the cathode, responds to maximize power output. Experimental study on two kinds of membranes, dialysis membranes and Nafion 117 films were done, by studying their fuel cell output voltage, current and power effects. Previous experiments showed that the optimal output of the battery is at 0.250 M glucose solution, Therefore, experimental conditions for glucose concentration is fixed on 0.250 M and sodium chloride solution concentration varies from 0.500 to 4.000 M. II. Procedures The Effect of Dialysis Tubing on voltage and current of the fuel cell 1. Pour 50 cm3 1.000 M NaCl (aq) to each compartment of the beaker separated by dialysis tubing. 2. Pour 0.250 M Glucose Solution into the compartment representing anode. 3. Connect the cell to two multimeters, which act as a voltmeter and ammeter respectively 4. Take the reading of the multimeters after 30 seconds 5. Repeat steps 1 to 4 twice for the second and third reading of the cell. 6. Take average value among three values as the final reading of the cell. 7. Repeat steps 1 to 6 with NaCl (aq) with concentration of 0.000 M, 0.250 M, 0.500 M, 2.000 M and 4.000 M to obtain the remaining data. The Effect of Nafion 117 on voltage and current of the fuel cell 1. Add 50 cm3 1.000 M NaCl (aq) and 50 cm3 of 0.250 M of glucose solution to the beaker. 2. Add 1.000 M NaCl (aq) to the Nafion 117 membrane pouch, and silver plate was put inside to become the anode. 3. Connect the cell to two multimeters, which act as a voltmeter and ammeter respectively 4. Take the reading of the multimeters after 30 seconds 5. Repeat steps 1 to 4 twice for the second and third reading of the cell. 6. Take average value among three values as the final reading of the cell. 7. Repeat steps 1 to 6 with NaCl (aq) with concentration of 0.000 M, 0.250 M, 0.500 M, 2.000 M and 4.000 M to obtain the remaining data. III. Result of Experiment 3 The result had shown that when the solution does not contain glucose (i.e. Glucose concentration equals to 0.000 M), Nafion 117 Membrane Cells have similar power outputs compared to the dialysis tubing cells. However, in 0.250 M glucose solution, the output of Nafion 117 membrane cell is about 1 to 5 times more compared to that of dialysis tubing cell. According to the experiment results, it was found out that the power output was maximized when the concentration of glucose solution and NaCl (aq) are 0.250 M and 4.000 M respectively. Under this concentration, the out of Nafion 117 membrane cell was 1336.68 nW which was 5 times higher than that of dialysis tubing cell. Hence, adopting Nafion 117 as the selectively membrane can greatly enhance the output of cell. It is believed that the special structure of Nafion 117 has limited the movement of glucose molecules, and prevented their oxidation at cathode. This has enhanced the oxidation of glucose at anode, and thus increased the power output of the cell.

由此次科展，我們發現國內基礎國小、國中、高中之科學教育，己慢慢揚棄以前教條式、公式化之教學，學生己能培養主動去挖掘問題，並實際動手去搜集資料，以實驗去作驗證之精神。對實驗數據之分析，亦能使用正確之方法，國中生甚至國小學生亦能使用電腦作數據處理，並用網路去尋求答案或資料，實為難能可貴，亦可頂期我國教育之向下紮根表現，此為國內教育升學管道多元化以後，學生唸書不再以升學目標作導向之結果，以及中小學教學生活化、趣味化之結果。 另與去年比較，今年的國中、高小及初小三組題材比較活潑具有創意的題目比較多，顯示這三組學生的思考有活潑化的傾向，對科展也比較用心。高中組則表現平平沒有特別值得一提之處，大約是升學壓力還沒有減輕。又作品多偏向現象的描述，如何量化還有待努力 〈 指導老師的指導相當重要）。
