本實驗使用磁流變流體(Magnetorheological fluid, MRF)來估查其磁場作用下的光學性質。本實驗採用Lord公司的MRF-132LD磁流變流體加以稀釋到不同的重量濃度，並以氫氟酸蝕刻玻片產生不同的厚度。吾人觀察到濃度參數以及厚度參數均對MRF薄膜的光繞射產生影響。膜厚越薄，產生的繞射較明顯，而重量濃度較小的容易亦有較大的繞射角度。吾人亦移動上下兩玻片相對位置，施加剪力的作用，繞射現象也產生明顯的改變。\r The Magnetorheological fluid (MRF) is used to observe the optical properties under the vertical magnetic field , The MRF-132LD from Lord Company is used, The MRF is diluted to different weight ratio of particulate and carrier fluid . The different thicknesses of the MR thin film are also made with the diluted MRF. The concentration of the MRF and the thickness of the thin film are both found to have significant effects on the optical diffraction phenomenon. The optical diffraction is also found to be affected by the applied shear force to the thin film.

光子晶體製程，是以苯乙烯為單體，十二烷基硫酸鈉為分散劑，過硫酸鉀當做起始劑，提供自由基誘發自組裝聚合反應，形成奈米到微米級的白色聚苯乙烯膠態溶液。將此膠態溶液滴於玻片上，以50~55℃加熱，在蒸散過程中，藉由毛細、界面力作用，自組裝結晶，從無序結構，變成有序的聚苯乙烯光子晶體，透過光照呈現艷麗色彩。由探討製程條件，發現： 1.加熱時間、溫度、單體濃度、分散劑與起始劑濃度，會影響自組裝晶體球尺寸 2.由球體自組裝變項，歸納製程間的交互作用 3.由球體尺寸對色光波長折射，發展簡易尺寸檢測法實驗發現：利用變因間的交互作用，除簡化流程，降低製作難度外，還可調配製造出不同尺寸的聚苯乙烯球，進而自組裝出各種顏色的光子晶體！

Nicholas’s project is a transforming robot, who he has named Reggie. He's about a foot tall and can transform from a biped into a vehicle and vice versa?\r Reggie has been Nick’s project for just under a year now, mainly working on him in technology classes. He operates without physical connection to anything else, so everything he needs from micro controllers to power is stored somewhere on Reggie’s body?\r Reggie is controlled through a programmable Arduino board (programmed in C++) that is connected up to a motor driver, for controlling the two driving motors and an SSC-32 servo controller for controlling the 14 servos via serial port. The Arduino uses the SSC-32 to coordinate the servos movements using pre-programmed sets of movements stored in procedures in order to complete all actions.\r All the parts were produced on a 3D CAD system to begin with, as well as the robot as a whole, although the design did change drastically over the course of its construction and now is considerably different from the original design as there were many problems and complications ranging from space to torque issues that called for a change in design.\r Most of the parts were from the servo erector set from lynx motion, although some of them were used in the way they were intended to and most of them were modified slightly. Some parts Nick manufactured himself either on a rapid prototyping machine, a lathe or milling machine and sometimes a combination of them or even high temperature soldiering?\r Currently Reggie is capable of driving and standing up and is currently radio controlled. He will eventually be capable of walking and modifications to allow him to (such as stronger leg servos) have been made to facilitate that, but it is possible more may have to be made.

在漫畫書堙A我常看到背著房子走路的蝸牛，總有一對斗大的眼睛，畫家們很誇飾地畫出牠那長長觸角上的兩個圓球，真吸引人。這時，引起了我的好奇，蝸牛的眼睛真是長在觸角上的嗎？真的能看到東西嗎？有沒有除了「看」以外的功能呢？因而對牠的眼睛產生了研究的興趣，於是邀了三位同學，一起展開一連串的實驗研究。 為了研究蝸牛眼睛的祕密 · 我們先搜集有關的賣料，再把這些資料，加以分類、處理，得知：鍋牛的眼睛生長的位置，大致可以分二類，一類是眼睛長在觸角的頂端，另一類是眼睛長在觸角的基部。 眼睛長在觸角頂端的蝸牛，通常雌雄同體，且頭上長有二對觸角，後觸角也稱為「視觸角」。而眼睛長在觸角基部的蝸牛，通常雌雄異體，且頭上只有一對觸角。

滿足之M 點，我們稱之為Pi(i=1…n)的均值點。當n=3，M 恰為△P1P2P3 的重心 (G); n=4 時，M 亦為三角錐P1P2P3P4 的重心！因此不免引人遐思：滿足之M 點是否皆為其重心？ 我們藉由電腦幾何作圖軟體GSP 協助觀察，掌握了圖形變化間之不變性，再配合向量解析及推理，得以發現均值點、多邊形的重心、以至多面體的重心、及平行多邊形的一般性作法。附帶又發現：任意相鄰三頂點即可決定一平行n 邊形。並進而證實：平行四邊形為四邊形M＝G 的充要條件。但當n≧5 時，平行n 邊形只是n 邊形M＝G 的充分非必要條件！一般而言，具有對稱中心O 的n 個點所構成的圖形必可使M 與G 重合於O 點上。 The point M satisfying is called “the mean point of Pi(i=1…n)”. As n=3, M is the center of gravity (G) of the △P1P2P3. If n=4, then M is also the center of gravity of the triangular pyramid P1P2P3P4. Therefore, I began to wonder if the following assumption stands: The point M that satisfies is always a center of gravity. By using the computer software GSP (The Geometer’s Sketchpad) to observe figures. It is found that when a figure is changing there is still constancy. Furthermore, supported by the analysis based on vectors, general constructions can be established concerning the mean point, the center of gravity of polygon, the center of gravity of polyhedron, and the parallel polygon. Also, I find that any three neighboring vertexes decide a parallel polygon. And thus it is verified that the parallelogram is the sufficient and necessary condition for quadrilateral M=G. As n≧5, the parallel n-sides shape is the sufficient, not necessary condition, for n-sides shape M=G. In general, a central figure of n points having the center of symmetry O can make M and G meet on O.

團藻(Volvox)，又稱大團藻，是一種由上面，至上千個細胞組成的綠藻。它的體制介於多細胞生物和單細胞群體之間，所以我們可以稱團藻是一個「群體」(colony)，也可以稱一隻團藻是一個「個體」(organism)。台灣在彌陀以及中南部養殖場都曾經有發現之紀錄。\r 團藻細胞雖然分布呈中空球體，但細胞已有分化的現象，它擁有形態類似衣藻的「體細胞」(sometic cells)，和體積較大、無鞭毛的「無性生殖細胞」(gonidia)[1]。先前的研究學者根據觀察，粗略地將團藻體細胞的差異現象區分為：眼點較大的體細胞，分布於團藻運動時的前端；反之，靠近後端的眼點則較小，這種現象稱為「極性」(polarity)[2]，極性形成的過程稱為「極化」(polarization)。\r 眼點是藻類運動的重要依據之一，藻類眼點的成份包括了胡蘿蔔素(carotene)及其他種類的脂質，其中胡蘿蔔素是由葉綠體合成再後運到眼點中。眼點含脂質的多少與細胞內狀態有密切的關係，目前我們已經知道：在一些藻類衰老的細胞當中，眼點的體積會逐漸減小。[3]但是有關團藻眼點的大小問題，目前尚未有相關的研究。\r 我們推測，因為團藻是一種趨光性的綠藻[4]，所以其運動情形的「極化」可能也與眼點的「極化」有密切的關係。本次實驗利用共軛焦點顯微鏡(confocal microscope)，對於團藻標本中各個體細胞的眼點大小做出定量的測量，並運用數學模型和統計學，來分析不同位置體細胞的眼點是否有顯著的大小差異，以了解團藻個體中眼點極化的情形。\r 團藻被許多發育生物學家視為一種有趣的模式生物，探討並證明其極化的現象，也算是讓我們對它的發育過程有進一步的認識。

本篇研究利用網路攝影機、DVD-R光碟片、木製暗箱、比色管、筆記型電腦、各式燈泡等器材，搭配上自行撰寫的程式，製作出一簡易的光譜儀系統。先經由實驗測試，找到最佳光柵角及觀測角的組合，再將DVD光柵及網路攝影機封裝在木製暗箱中，完成硬體製作。軟體使用VB.Net搭配EmguCV函式庫當作平台，發展出來的程式可以利用螢光燈光譜中的特徵線條進行頻譜校正，校正完成後可以精準且即時地顯示各種光源頻譜曲線。此外，我們也以自製的光譜儀系統進行不同濃度之硫酸銅溶液的吸收光譜檢測，與專業的光譜儀的吸光度做比對，數據非常的接近，代表以本研究方法自製出來的光譜儀確實可用。

在高職機械科二年級專業課程機件原理中有討論齒輪減速機內容，以章節內容我們知道工程應用上減速機以齒輪式的設計使用最為廣泛，但除了齒輪外是否還有其它以機械方式來達成減速的可能。本專題將探討設計、製造非齒式且相同尺寸只需更動少數零件即可達到不同的減速比之減速機的可能性，藉由創意機構設計方法及流程，來設計非齒輪式的減速機。本裝置共有五個零件分別是支撐座、自轉子、立體凸輪基座、波形產生器、鋼珠相互配合，藉由波形產生器對鋼珠產生壓力而促使鋼珠延底座之特殊曲線而作圓周運動，達成減速的目的，此裝置速比可藉由調整底座鋼球數量達到不同的減速比，本專題經測試後可達到減速的功能及穩定的轉速輸出。

本研究合成含環形胺—亞胺雙牙配基鎳金屬催化劑，用以催化烯烴聚合反應。將2-甲基丙醛經由溴化、胺化及亞胺化的步驟合成含胺—亞胺的雙牙配基，Et2NCMe2CH=N(2,6-iPr2C6H3) (3a)、(c-C4H8)N- CMe2CH=NPh (3b)、RNCMe2CH=N(2,6-Me2C6H3) (R = c-C4H8 3c，c-C5H10 3d)。再將配基和Ni(DME)Br2 (DME = 1,2- 二甲烷氧基乙烷) 反應， 形成鎳金屬錯合物Ni [Et2NCMe2CH=N(2,6-iPr2C6H3)]Br2 (4a)、Ni[RNCMe2CH=N (2,6-Me2C6H3)]Br2 (R = c-C4H8 4c，c-C5H10 4d)，並作結構鑑定。其中3b、3c、3d、4c、4d 均為合成的新化合物，4d 獲得X 光單晶繞射結構。 以合成之鎳錯合物作為催化劑，催化乙烯或降冰片烯(C7H10)的聚合反應，探討反應活性和高分子產物的性質。與含相同碳數的錯合物比較，在胺基具環形取代基的錯合物對乙烯的催化活性較佳，聚乙烯產物分子量較高，分子量分布範圍狹窄；其對降冰片烯的催化活性略遜於非環形者。同為環形取代基時，六環較五環者對乙烯的催化活性較差，但對降冰片烯的催化活性較佳。顯示乙烯聚合與降冰片烯聚合有不同的反應決定步驟。催化劑及配基的設計的確可以操控聚合反應及其高分子產物的性質。 The synthesis of α-amino aldeimines Et2NCMe2CH=N(2,6-iPr2C6H3) (3a), (c-C4H8)NC Me2CH=NPh (3b), RNCMe2CH=N(2,6-Me2C6H3) (R = c-C4H8 3c，c-C5H10 3d), as well as the nickel complexes Ni [Et2NCMe2C- H=N(2,6-iPr2C6H3)]Br2 (4a), Ni[RNCMe2CH=N (2,6-Me2C6H3)]Br2 (R = c-C4H8 4c，c-C5H10 4d) has been succeeded. Their structures were mainly determi ned by spectroscopy or elemental analysis. The complex 4d was characterized by X-ray crysta llographic analysis. It shows that the nickel complex has distorted tetrahedral configuration. The catalytic reactions of ethylene or norbornene polymerization using the newly synthesized nickel complexes are studied. All catalyts show high activity toward studied olefin polymerization. Comparing the data of the catalytic ethylene polymerization for complex 4c with those of its isomer complex 4a, the former is found to results in higher activity as well as the larger molecular weight of the PE products with the narrower dispersity. On the contrary, 4c shows lower activity in the reactions of norbornene polymerization than 4a. For the cyclic amine derivatives, 4c of five-membered amino group shows better catalytic activity toward ethylene polymerization than 4d of six-membered amino group. But 4d gives better perfomance for norbornene polymerization than 4c. Such results indicate that the processes of ethylene and norbornene polymerization might have different rate-determining steps. These study confirms that the design of ligand and catalyst are crucial with respect to the control of the catalytic olefin polymerization and the properties of the polymeric products.

本研究利用麥克風與相關電腦設備，結合成自製頻譜儀用以觀測多種情況下蜜蜂的聲音頻率。若將蜜蜂的翅膀加以修剪，可測得有不同的頻率，解析頻率發現「翅膀為主要發聲點，但去除翅膀仍有高頻的發聲，且有三種不同的頻率。」將蜜蜂置於不同溫度下，解析頻率得知「一定溫度範圍內，溫度越高蜜蜂發聲頻率越高，反之亦然。」幼期在胸部塗顏料使絨毛無法生長，去除雙翅後，仍有頻率相近的發聲，得知「胸部絨毛不是造成高頻的原因。」靜置５分鐘，待蜜蜂停止發聲後，剪去腳、挑弄蜜蜂會發出高頻，得知「情緒是引起高頻的原因。」將蜜蜂的翅膀加以修剪，分別放回蜂窩口，發現「同一族群蜜蜂可用發聲頻率來辨別同伴。」比較義大利蜂及中華蜜蜂，得知「在多種情況下中華蜜蜂發聲頻率皆較義大利蜂高約７０Hz。」因此本實驗之結論並不受蜂種影響。The study, capitalizing on a hand-made frequency divider, the microphone and computerized equipment, observes a variety of frequency of sound given off by bees. We read different frequencies from the apparatus when the bee’s wings were trimmed. Analyzing it, we discover that the bee’s winds are major source of its sound, but it still gives out high-frequency sound when the wings were completely cut off.” After analyzing the frequency, we discover that within a certain temperature range the higher the temperature is, the higher the frequency is, and vice versa. In one experiment, we painted the thorax at its pupal stage to stop the bee from growing fine hairs. Even though the wings had been removed, it still gave out high-frequency sound. We, therefore, conclude that fine hairs on the thorax have nothing to do with the making of the sound. In another experiment, bees were placed in an undisturbed environment until they are completely silent. Then, some of the bee’s legs were cut off, while others were provoked. And all the bees make high-frequency sound in the process. We make a hypothesis that emotion could be the cause of bees’ sound-making. The bees with different trimmed wings were put back to the beehive; the bees can still recognize one another by the different sound frequencies. If we compare A. m. ligustica with A. c. cerana under different conditions, we find that the frequency from the latter is about 70 Hz higher than that form the former.

本研究工作自2001 年7 月至2002 年6 月止，在臺北市內湖區金面山進行地衣實地探勘採集調查，以位於臺北市內湖區之麗山高級中學之校園為中心點，範圍由校園金面山至學校前門所面對的港墘路與環山路口。應用「外部型態比較」，「切片觀察(徒手切片技術)」與「化學分析(薄層色層分析Thin Layer Chromatography, TLC)」等三種方法，鑑定所採集之地衣所屬種類，並探討空氣污染程度對金面山地衣類分佈狀況的影響。調查至2002年6月為止，本研究已發現生長於金面山區之數種地衣，其中殼狀地衣包含有：癩屑衣屬(Lepraria)、球粉衣屬(Spheophorus)、大孢衣屬(Megalospora)等三屬；屬於莖狀地衣的僅有石蕊屬(Cladonia)；為葉狀地衣的則有：黃梅衣屬(Xanthoparmelia)、裸緣梅衣屬(Parmotrema)、梅衣屬(Parmelia)等三屬，合計共七個屬。本研究針對臺北市金面山區及麗山高級中學之校園附近市區道路地衣類分佈的情形做調查，結果發現行道樹上之附生地衣在較靠近山區的地方，於樹幹上的生長覆蓋面積才會有明顯增加的情形，又其中在市區道路上只發現殼狀地衣生長，而莖狀及葉狀地衣則出現於金面山頂附近，所以就此情況而言，除了金面山區外，市區已呈現地衣沙漠化之狀況，間接顯示，市區的空氣污染是相當嚴重的。本研究將所調查結果之各屬地衣類進行特徵描述與分佈地區之標定，以便於日後臺北市內湖區金面山地衣之鑑識及後續相關研究之進行。This research was carried out between July 2001 and June 2002 on the Jinmian Mountain in Neihu,\r Taipei City and consisted of an on-the-spot exploration and collection of lichen. The Taipei Municipal\r Lishan High School was the center of this research, and the researched territory consisted of the areas\r between the mountain at the back of the school (Jinmian Mountain) and the intersection between\r Gangcian Rd. and Huanshan Rd. in front of the school’s main gate. Comparison of external appearance,\r dissectional observation (manual breaking technique), and chemical analysis (Thin Layer\r Chromatography, TLC) were the research methods applied to determine the genus of the lichen and the\r influence of the degree of air pollution on the distribution of the lichen.\r By the end of the research in June 2002 the presence of three types of lichen on the Jinmian\r Mountain was observed: crustose lichen: Lepraria, Spheophorus, Megalospora; fruticose lichen: Cladonia;\r foliose lichen: Xanthoparmelia, Parmotrema, Parmelia. Seven different genus of lichen have been found.\r The research has been done on the distribution of these different genus of lichen in the area of the\r Jinmian Mountain and The Taipei Municipal Lishan High School: By observation the sidewalk trees\r near the mountain’s area, we found the covering area of the lichen on the sterns apparently increases,\r while on the trees in the city district, only crustose lichen grow. The fruticose and foliose lichen only\r grow near the top of the Jinmian Mountain. This impoverishment of the diversity of lichen in the city\r district might (indirectly) be an indicator of the considerable decline of air quality in the city. The\r outcomes of this research regarding the description and distribution of the lichens contribute to the\r knowledge on lichens in the Jingmian Mountain area in the Neihu District, and may raise the similar\r research in the future as well.

This study is to discuss the reason that interfere the fish schooling behavior " adult fish surround the young fish ". I use mathematic simulation, to observe the result when the fishes are stimulated, due to the body size , the speed of swimming , the difference of sensitivity will make different reaction. We predict the motion dots of fish when the hunter appears on the block paper, then analyzes the motion of adult fish and young fish in dot to determine if the result remind "adult fish surround the young fish "structure. The conclusion shown that natural reaction physiologically on fish will show "Adult fish surround the young fish "results, so, the factor that interfere the structure of fish group is not so called "group defense by ethnologist".本研究目的，在探討影響魚群「成魚圍繞著幼魚游」的行為。本研究是以數學模擬法，依觀察結果，設定魚在受到刺激後，因體型大小、游速的快慢、靈敏度的差異等，所產生的不同的反應。再在方格紙上模擬魚群在捕食者出現時，游開的動線。最後分析成魚幼魚的動線分布情形，是否仍是「成魚游在幼魚外圍」的魚群結構。研究結果發現，依魚類的生理條件所設定的條件下模擬，自然形成「成魚游在幼魚外圍」的魚群結構。所以，影響魚群結構的因素，的確不是行為學家所說的防禦行為。
