The purpose of this research is to create a device that is able to precisely measure small dynamic changes which cannot be recognized by the human eyes. The Vernier Caliper and the screw micrometer are common tools used to precisely measure lengths of objects. However, things which are measured by the Vernier Caliper or the screw micrometer have to be in a solid state, and the shape cannot be changed. By applying the light lever principle on Lego bricks, this research uses the LabVIEW graphical programming system to design a device which is able to automatically measure small dynamic changes. The precision of this device is higher than that of the Vernier Caliper and the screw micrometer. Moreover, this device is able to precisely detect the small dynamic changes of solids and liquids as well. Through numerous tests, the least count of the device can reach the level of 10-3cm. Also, this device has successfully measured small changes, such as the height of the liquid surface by one drop of water, the evaporation of water in one minute, and the growth of a plant in one hour. By popularizing this device, people will be able to precisely measure small dynamic changes which are difficult to be measured in a short time.

本實驗以硫酸銅與明礬為研究對象，探討影響化學結晶的因素。主要是用外在聲音頻率來影響物質結晶。我們發現硫酸銅的結晶量在每隔300Hz之下，均會突然增加；但明礬卻是隨著聲音頻率的增加而做某種規則性的遞減。除此之外，音頻對於硫酸銅結晶的外在形狀也有著某種影響，大致上在1000Hz以下，較易呈現長圓柱形；在1000Hz以上，則較易呈現小針狀形。為確認音頻的確會影響化學物質的結晶，我們更利用駐波的共振與共鳴原理，對著長玻璃管柱施放一系列音頻，竟可得到一規則性的節狀結晶體，然而目前我們對於此複雜之物理駐波原理並未能了解，故無法做一整體性探究。最後，我們仍以改變溶液中的離子，如加入食鹽、酸離子、鹼離子等方法，來研究對於化學結晶是否有影響。

我們在三年級自然課「我們需要太陽」裏面學到「太陽的光射到地面上有一部份變成熱等……」因此發生了一個疑問：「晴天時校內什麼地方溫度最高？」同學紛紛爭論著，不能得到一個結果最後去請教林老師，在林老師指導下，老師帶我們到校園裏，實地觀察測量，並用各種東西做實驗看那一種東西最容易吸熱，我們就研究觀察太陽的熱能。

本人自幼對花為生態頗感興趣，而在民國五十二年暑期開始，對「金絲鳥」興起一股熱熾的研究心潮，經過有計劃的籌策，共花了新台幣一萬二千元購買十對（二十隻）黃金絲鳥和飼養設備，利用課餘之暇加以潛心研究，繁殖生產，由十對繁殖成五十對，以至一百對，二百對，三百對，至今十餘年巳育成六百對之多，年產幼鳥可達五千～六千隻，可說稍具規模，目前並兼台灣省飼鳥協會理事長之職，職貴所在，乃深加探討研究，特殊繁殖效果以及品種改良，以促進本省飼鳥業之進展，玆將個人五年來操作研究，實驗過程所得結果、統計、分析報告于后。

學校、捷運…等公共場所的廁所，雖然都有提醒大家使用完畢後要沖水的標示，但仍然有部分的人有看沒到，造成下位使用者的不便。為了減少環境的髒亂，因此我們針對以上問題以學校所學的專業知識以純機械結構構想出自動沖水裝置，以電腦輔助繪圖預先判斷結構合理性，並進行實驗與測試、記錄其結果。使用者在使用座式馬桶時一定會使用到馬桶蓋，而馬桶蓋是以固定軸心旋轉的座墊，與機械傳遞動力的方式類似，啟發我們連想該部位可以當作是機構啟動的部位。配合合理的機構設計期望能達到當初設定題目的目的，就算方便完後忘記沖水，在下一位使用者來之前，也會自動幫你清理排泄物。而且本設計不需電力即可做用，不但節約能源也為地球盡一份心力。

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.

To-be static objects, such as bridges, volcanoes, seldom move ordinarily but have mini displacement only under special conditions, like flood or earthquakes. Therefore, how to measure their mini displacement has never become fully popular with scientists’ research. Then, beginning with “ Optical Lever Theorem”, through a series of speculation and discussion, I decide to use laser ray as light source to perform an experiment ------- trying to find objects with mini displacement in our daily lives, such as revolving electric fans, engine-opening motorcycles, shaken trees, testing their magnifying effect first. Next, I try to use the control-experiment method to find out the magnifying relation and formula of the rotation angle of the plane mirror and the displacement quantity of light focus. As to the measure of mini displacement on objects, I utilize the pillar mirror as a reflection plane to research the magnifying relation of reflection light focus and original displacement quantity. The image made from the light focus of pillar mirror’s reflection, however, isn’t so perfect that I have to use a special plastic-made light-concentrating mirror, which is also called “ Fresnel Lens ”, to focalize the light for easy observation. Besides, I find out the “ function graph ” of the mini displacement quantity on to-be static objects and the displacement quantity of reflection light focus. At last, I try to build up a “ Bridge Alarm System ” of Optical Lever Theorem. 準靜物如橋樑、火山，由於平常不輕易移動，只有在特殊情況下（如洪水、地震）時，才會發生位移的現象。因此，其微小變位如何測量，一向是科學界較少探討的題目。於是，先由光學槓桿原理著手，經過一番思考、探討，決定採用雷射光作為光源，並作了第一個實驗－－找生活中具極微小變位的東西，如轉動中的電扇、引擎發動的摩托車、被搖動的樹木等，先測試其放大效果。接著就試圖用控制變因的方法，找出平面鏡旋轉角度和光點平移量的放大關係和公式。至於物體微小的平移量之測量，則是利用柱面鏡作為反射面，來探討反射光點的位移與本來的平移量之放大關係。然而，柱面鏡的反射光點成像並不理想，於是用一種特製的塑膠集光鏡，又稱Fresnel Lens，將光點集中以利觀測，並且找出準靜物之微小平移量及反射光點的位移量的函數圖形。最後，嘗試建立一套光學槓桿式的「橋樑預警系統」。

Reflex charging, or burp charge, is a prove method of effectively charging secondary\r batteries under extremely high current. It is commonly used in military and aerospace\r applications where short recharge time and long cell life are essential. Eric C. Darcy, a NASA\r chemical engineer, in his 1998 PhD thesis, ‘Investigation of the response of Ni-MH cells to\r burp charging’, outlined some of the most important theories behind this seemingly\r miraculous technique. However, due to the technical limitations of his equipment, Darcy was\r unable to determine the effects of varied reflex charging frequencies. This research overcame\r this problem by using a purposed built multi-frequency programmable reflex charger\r (PRESTO ALPHA I), and aimed to optimize chemical energy storage by searching for an\r optimum charging frequency.

我們的實驗目的主要是探討蠟燭在打洞的塑膠瓶中如何延長燃燒時間？進而製作氧氣量控制器以持續供應氧氣，找出瓶外空氣與瓶內二氧化碳的對流方式，確認我們推論是否合理。經實驗發現，橫列和縱列上的洞數越多、縱列的數目越多，蠟燭的燃燒時間越長、同一縱列時，一個洞：開上、二個洞：開上中，蠟燭燃燒時間較長。最後並由實驗證明空氣容易由開中的洞進入，二氧化碳則由開上的洞離開，以形成氣體對流。

近年來，因每年舉辦的「全國科學展覽」，而培養了不少的科學人才，可真是值得喝采的事跡。但是，不可否認的，仍有無數的教育工作者一談起「科學研究！，總以為是一門莫測高深的學問，如要他們也來從事研究，而個個面有難色，有力不從心之感。然而，目前從事白然科學教學的老師，已不限於科任老師的職責；由於新課程的實施，許多學校的自然科學的教學挪轉移在級任老師的身土，雖然人部份老師也都接受了「新課程」的演習，能夠真正的把握「新課程」的新精神的人，仍是占少數。追究原因，發現是由於缺乏「研究」的整體概念，以及未曾獲得「科學能力」所致。試想：教師本身如缺乏能力，叫學生如何的「有能力」呢？縱之一想，我們的祖先所留下來的多少「祖傳秘方」，為什麼會失傳，為什麼外國人不肯承認它的價值，非要外國人用它來從事研究後才肯定它的貢獻？那是因為外國人會做研究計劃，會把握科學精神來實驗、研究；能從研究報告中拿出證據來。有鑑於此，我們開始為人人應該培養的「科學能力」和「撰寫研究報告」作深入的研究與探討。

重心的等積性質引發我們對等周分割的興趣，本研究的周心定義為與△ABC同平面上，使得OA+OB+AB=OB+OC+BC=OC+OA+CA的O點。我們透過分類技巧與圓冪性質成功找出任意三角形周心的作圖方式、周心存在與否及位置的判別式，並找出與周心息息相關的環圓。我們並成功透過環圓，逆向推導找出另一種周心的作圖方式。

主要在探討：影響刷刷車在地面的行進路線及其速度的因素，含括了電池與馬達的位置、多少；旋臂的長短與重量；刷毛的長短與排列方式等。行進時無法定向的刷刷車，過程中不斷提出使車子走得更直、更穩的方法。並發現自製、改造的「保特瓶車」其實比「刷刷車」，更具備了在直線行進方面的穩定度，並呈現兩種車在直線行進與速度上的比較。
