地球具有磁場，地球磁場影響了許多生物的棲息及遷徙行為。本研究透過外加與地磁方向不同的磁場，來了解蓋斑鬥魚的各項行為是否受外加磁場干擾影響。實驗發現外加磁場下：蓋斑鬥魚的方向判別能力降低，常有錯誤情形：蓋斑鬥魚的方向判別能力降低，常有錯誤情形：蓋斑鬥魚的方向判別能力降低，常有錯誤情形：蓋斑鬥魚的方向判別能力降低，常有錯誤情形發生；牠的覓食行為在磁場干擾下所需時間增長，次數也減少；的覓食行為在磁場干擾下所需時間增長，次數也減少；的覓食行為在磁場干擾下所需時間增長，次數也減少；的覓食行為在磁場干擾下所需時間增長，次數也減少；蓋斑鬥魚的胸鰭、尾擺動次數蓋斑鬥魚的胸鰭、尾擺動次數蓋斑鬥魚的胸鰭、尾擺動次數幅度也受其影響；變得比較好動，不會長時間停留在同一位置。我們也發現蓋斑鬥魚的某些行為與外加磁場沒有太大關係。例如：無論。例如：無論。例如：無論。例如：無論有無外加磁場，其都喜愛較暗的地方；偏愛深色、喜歡溫暖的水域好棲息在底部習慣逆流而上。此外蓋斑鬥魚的記憶能力也不受外加磁場干擾。

本實驗主要是藉由控制三個變因，以探討大自然中影響波痕產生的情況。藉由改變水波的頻率、水槽中的水深、沙子的粒徑大小，將其所產生的波痕的波峰、波谷的高度以及各個波峰離起始點的距離記錄下來，並且製作圖表，希望能從中發現各變因對波痕的影響，並希望能藉由該發現來推斷出一個可以分析波痕與沉積環境的關係。經由實驗，我們發現水波的頻率越高，波痕的波痕指數越小，且其高峰值離起始點的距離會越遠，而所形成的波痕振幅之臨界質不隨頻率改變。此外，我們也發現在較深的水中，形成完整的波痕的時間較久，而沙子粒徑分佈也會影響其產生的波痕。

酵母菌分為麵包酵母和酒麴酵母，大致呈橢圓形單細胞的形態，有一點點異味。酵母菌發酵時需要有糖，但是糖的濃度增高，發酵速率不一定增高。不過酵母菌濃度愈高，發酵就會愈快。酵母菌發酵時最喜歡在新鮮的環境中，所以蔬果汁愈新鮮，發酵的速率就愈快，另外，用來發酵的蔬果汁如果煮過了，就會破壞促進酵母菌發酵的物質，發酵的狀況就比新鮮時還差。如果把酵母菌放在酸性、鹼性及含鹽的溶液中，是不適合酵母菌生長的，但是放在沙拉油裡面，卻不會抑制酵母菌的發酵。而有酵母菌的地方，黴菌是不容易生長的。

我們一開始從雪花繁複又有規律的圖形得到靈感，並尋找了一些水結晶成冰、霜的圖片，發現其形狀雖然複雜，但皆同時具有「相似」及「無限規律」的特性。因此便以這兩者為方向，找尋符合此特色的圖形進行討論及研究。其中我們將它們分為兩個單元：（一）不斷向外/內延伸的內切/外接圖形；（二）相似形重覆以規則方式相疊的碎形。我們的研究方式是先以較簡單的內切/外接圖形為基礎，再針對一些參考資料上較常見的基本碎形圖案（如三角形相疊成為星形...等）進行演算。有了上述的經驗後，便可以開始對碎形的形狀等特性進行變化，進而製造出我們有特色的碎形，並探討其圖形間奇妙的關聯性。

記得有一天，我們學校午餐供應的米飯，竟然是黃飯，當時好幾位同學異口同聲的叫出來，「今天吃黃飯」。真是奇怪！為什麼飯是黃的呢？我曾吃過紅飯，是加蕃茄醬而變紅的，但黃飯乃是第一次看到。為解開心中之謎，就請教老師，老師笑著說：「白飯加入咖哩粉就變成黃色的咖哩飯了。」但是咖哩粉到底是什麼東西呢？有什麼性質呢？所以我們就利用團體活動時間或課餘，對咖哩粉做進一步的探討。

我們實驗得知影響光傳輸聲音因素有：發射端的音源與接收端太陽能板的接法、發射端感應線圈的圈數、中間使用的介質、發射端的光源、太陽能板的選擇，均會影響聲音傳輸的效益。 經實驗發現要有效光傳輸聲音條件: 1. 發射端的音源要使用串聯，且正極要接接地，電感要接左右聲道，接收端太陽能板正極與接地相接，負極與左右聲道。 2. 發射端感應線圈建議使用圈數10圈且口徑為3cm。 3. 當發射端與接收端越接近且中心線左右徧移10度皆有良好效果。 4. 白光屬於短波的光源效果比長波的效果好。 5. 接收端太陽能板建議使用3V單晶矽效果最佳。 以上發現應用於學校國學情境區導覽時，學生可以由簡易的設備聽到介紹與說明。

我們設計一系列的實驗來探討為什麼水芙蓉的根需要那麼長。我們以剪根的方式來檢測對植株的影響，結果發現根有吸收養分的作用，但是只要長到一定程度就能達到養分吸收的目的，根再長對養分吸收似乎沒有特別的幫助。根重改變對水芙蓉翻正有很明顯的影響，但根長改變則影響不大，顯示根的重量對穩定有重要的影響，但實驗也發現根部太重對植株也有不利的影響。植株型質分析發現葉子提供浮力，而根的重量提供穩定作用，使之不會在水面上亂漂或可能翻覆。最後，生長在各水域的植株根會隨水愈深而愈長，實驗結果支持我們的假說，即是水芙蓉根的長短和穩定有關；同時也暗示水芙蓉的生理具可塑性，能依其生活環境的不同，對根或葉部做不同能量的投資。

Many people in South Africa still use open fires for cooking. There is a\r large amount of wasted heat lost by four methods of heat transfer:-\r radiation, convection, conduction and evaporation.\r I constructed a vessel that would reduce heat loss, and focus the heat\r emitted from a fire onto the bottom of a pot. I used materials that were\r cheap and easy to obtain, so that those using open fires would be able to\r construct similar vessels to save energy and reduce pollution.\r The vessels were made up of a standard wire mesh frame that was\r surround by trial coverings, namely tin foil, asbestos rope, industrial foil,\r papier mache, ceramic, and 2 ceiling insulators.\r 5 mls of methylated spirits was burned in each vessel. The temperature\r gain of 100mls of water in a standard pot was recorded. 5 trials on each\r vessel were performed. 2 groups of vessel were found. Those that\r produced high temperature gains, burned quickly, and produced a large\r amount of soot deposits on the pot, and a second group that did the\r opposite.\r I compared the rate of heating from my best vessel to that of a stove as\r well as a microwave oven. Heating from the vessel was faster than that of\r the stove, and slightly slower than the microwave.\r I measured the heat emitted from a fire in a three-dimensional pattern and\r found that the maximal heat was some distance above the flame.\r From these results I devised 12 guidelines that would minimize the\r energy need, and pollution produced, when cooking on an open fire

Annually several baby’s and toddlers drown. There are safety devices available on the\r market for ex: Safety nets in which toddlers can get strangled. Pool covers that have to be\r taken off when people swim and replaced after they have swam. If they are not replaced\r afterwards, babies could fall in the water and drown. Fences around the pool:- The gate\r could accidentally be left open and the toddler could fall in and drown.

利用陰極電弧蒸鍍各種薄膜，如：類鑽膜（DLC）、氮化鈦膜（TiN）、氮化鉻膜（CrN）、氮化鋁鈦膜（TiAlN）以及先披覆上一層氮化鋁鈦膜（TiAlN）再加上類鑽膜（DLC）的合成膜等。這些薄膜現在已經被廣泛的應用於各種刀具、模具的表面處理之中。本研究主要在探討高速鋼鍍上氮化鉻膜（CrN）之後，對於硬度、磨耗性質的改變，以及觀察氮化鉻膜（CrN）表面結構之組織。 在研究中我們運用陰極電弧蒸鍍系統蒸鍍氮化鉻薄膜，分析上運用SEM來觀察薄膜表面結構組織，以及運用洛氏微硬度機來觀察試片的硬度，另外還有使用磨耗試驗機來進行磨耗測試。以上這些測試總括來說都是在得知性質有無實際上的改變，而這些實際上的改變對於蒸鍍之後的模具或刀具都能夠大幅的提高使用的壽命。 We evaporated different kinds of thin films by using the anode of the electronic arc, such as DLC (Diamond-Like Carbon), TiN (Titanium Nitride), CrN (Chromium Nitride), TiAlN (Titanium Aluminum Nitride), and synthetic films of covering TiAlN and DLC. These thin films have been used widely in processing the surface of a variety of cutters and moulds. The purposes of this research were to investigate changes of hardness and abrasion and to observe the organization of the surface structure of CrN after High-speed steel evaporates CrN. In this study, we use the system of the anode of electronic arc to evaporate CrN. Besides, SEM is used to observe the organization of the surface structure of the thin films and Rockwell Micro-hardness Test Machine is used to investigate hardness of testing samples. Moreover, we use Abrasion Tester to test abrasion. These tests are taken to lead to a better understanding whether the quality really changed. These changes of evaporated moulds or cutters would extend their frequency of using.

Contains two human-computer interfaces. The first is an interface for blind people to perceive visual sensations using his tongue. Images from a webcam is processed with artificial intelligence software and is placed as a sensory matrix under the tongue. Currently the sensor placed on the tongue is about 8x8 pixels. The sight and the taste divide similar areas on the cortex so the blind person can adapt very quickly to the image sent on his tongue as an electricity matrix. Taste buds are the second sensor matrix after the eyes(as resolution) is based on the same principle of the Braile code but the information is received by tongue and it's proportional with the image from webcam and the person can receive more informations. The second interface follows the intent of motion detection of a person with disabilities. It is based on processing the neural signal of the brain taken by an handmade encephalograph and processing them with a artificial intelligence on computer. The project contains hardware and software. This project tries to suggest that the human computer interfaces can be made to support people with disabilities.

本研究首先探討台灣各地的日照時數與世界重要都市的比較，發現台灣南部日照時數皆超過2000 小時，適合發展太陽能。接著，?了增加陽光的能量密度而加設弗瑞奈透鏡，雖然能順利的使照度放大三百餘倍，但歲日照角度的影響甚鉅，?了克服角度的問題，我們決定開發自製的追蹤器來改善角度的問題。太陽能板需要改變仰角跟傾角（雙軸調整），由光感應器判斷及自動控制程式，判斷隨時辰與季節變化的太陽角度。當搭配奈米塗料、弗瑞奈透鏡與追蹤器，總輸出功率可增加約50%。太陽電池表面玻璃會阻擋藍紫光的吸收，但本研究在太陽能板上塗佈奈米塗料，發現能增加短波長的吸收；經實驗後奈米等級表面具有自潔效應，可防止灰塵雨滴的堆積影響光線吸收，具有開發價值。This project first compares Taiwanese locations with other places in the world on average daylight times. It was discovered that southern Taiwan has the longest average daylight time all over 2000 hour sand therefore most ripe for solar power development. To increase the energy density of solar Fresnel lenses were incorporated. Although this has the advantage of magnifying illumination by three hundred percent, the alignment angle for the solar panel will have a significant impact on performance. We then designed and built a automated tracking device with illumination sensors to control the elevation and inclination of the solar panel which adjusts the angle according to environmental conditions such as time of day and season. When solar cell collocate Nano coating, Fresnel lens, tracking device, its power can promote almost150%. The glasses on the solar cell will interfere solar cell absorbing blue and purple light, but we lay on a Nano coating and we find Nano coating can improve solar cell to absorb short wave; and surface o Nano have lotus effect, it can prevent dust and rain effecting solar cell absorb lights, and it is worth developing .
