超越極限的越野蟑螂車
在本研究中，我模仿蟑螂的行走方式，來製作可以在各種地形以不減速的方式前進的機器車。在偶然機會下，我觀察到，蟑螂可以順利爬越米堆，因此對蟑螂的運動方式感到興趣。我用微型網路攝影機拍攝及觀察蟑螂的行走方式。發現蟑螂在快速行走時，是以三隻腳為一組，六腳兩組交互進行前進的動作。由於三點構成一平面，使蟑螂在快速移動時，相當的平穩。我將此原理融入蟑螂車的設計，並根據這個原理，利用舊玩具四驅車改裝成「六驅車」，成功的製作出模仿六足昆蟲行走方式且可以在各種地形順利前進的機器車。為了更客觀的比較，我應用樂高積木的馬達組合，製作了一部純轉動前進的六輪傳動車，及另一部轉動兼走動的六輪蟑螂車。並利用微電腦控制兩種車維持相同的驅動速度前進(93.33 rpm)，於各種路面實地測試，證實蟑螂車越野的性能的確強很多。未來若可以將六足昆蟲行走方式的概念應用到汽車製造，車輛的越野性能必然大幅提昇。\r \r In this research, I developed a six-wheel driving vehicle simulating the movement of cockroach. The resultant motion machine can un-intermittedly run on terrains without speeding down. Occasionally, I observed that the cockroaches can crossover a heap of rice. Therefore, I was very interested in and eager to learn how cockroach runs. I recorded the movements of cockroaches by using mini web camera and analyzed the moving characteristics of cockroaches. It was discovered that the cockroach marches quickly by interchanging two groups of foot in which each group consists of three feet. As a table can be supported by three legs, the cockroach runs steadily and rapidly. I have designed a motocross vehicle based on the mechanism of the way that cockroach runs. A six-wheel driving car is constructed by modifying four-wheel driving toy cars. By simulating the motion complex of six-foot insects, the six-wheel driving car turns out to be an all-terrain vehicle. To be more objective in comparison, I built two types of six-wheel driving cars by utilizing the LEGO TECHNIC motor building set: one with regular and synchronous rotation, and the other one with eccentric shaft rotation emulating cockroach marching movement. I applied a microprocessor to control the motors in order to maintain the same driving speed (93.33 rpm) for both cars during the road test. The experimental results show that the proposed cockroach motocross car performs superiorly especially for the rugged terrain. In the future, the off-road capability of a jeep can be improved by introducing the concept of six-foot insect movement to vehicle design.
『吸凍！』--再造保麗龍的第二個春天
中文摘要 本實驗先尋求將廢棄保麗龍磺酸化為陽離子交換樹脂(本實驗稱”保麗龍膠”)的方法。將保 麗龍依：丙酮溶解→硬化→打碎→與濃硫酸共煮三小時→浸於50%硫酸溶液中→沖洗→以水 浸泡的流程，即可達再造的目的；我們測得其磺酸化比例為62.5%。再利用「碘滴定法」(浸 泡式)與「相對電壓檢測法」(流動式)，依次尋求保麗龍膠吸附金屬離子的最佳條件。其中「碘 滴定法」可有效測出銅離子濃度，但手續繁瑣；「相對電壓檢測法」最大的好處是知道保麗龍 膠何時吸附達飽和必須再生。 目前我們所知，要保麗龍膠達到吸附陽離子的最佳效能，其條件依次為：使用細粒的保 麗龍膠；低濃度的金屬離子溶液；質量愈大的保麗龍膠；低溫下較慢的金屬廢水流速及pH 值約為4.30 的銅離子廢水；鈉型的保麗龍膠吸附效能優於氫型。保麗龍膠對不同金屬離子亦 有吸附力，單位體積所含離子數愈少，初始的相對電壓會愈高；在相同莫耳濃度下，不同離 子的吸附力依次為Cr3＋＞Fe3＋＞Ni2＋＞Cu2＋＞Co2＋；分次吸附確可將金屬離子完全去除；由 吸附等溫線觀察得知，可能保麗龍膠為多孔物質，導致500ppm 以下的吸附模式無法明確判 斷，1000ppm 以上則為物理吸附模式；保麗龍膠可以再生也可被覆在砂粒上達到不錯的吸附 效能；最後，我們將吸附過金屬離子的保麗龍廢膠與硫酸鈣、紙漿及些許的石灰(質量依序為 13 克、13 克、7 克、0.04 克)混合，可製成類似紙黏土，做成造型磁鐵，廢物利用十分有趣。 Abstract The Experiment will, first of all, explore the ways to sulfonate expandable polystyrene into cation ion exchange resin (called “polystyrene rubber” hereafter in the experiment). The procedures of treating expandable polystyrene are as follows: acetone dissolve→hardening→smashing→ boiling with sulfuric acid for three hours→immersing in 50% sulfuric acid solution→washing→ immersing in water so that we may reach the goal of reconstruction. We calculate the sulfonated rate to be 62.5%. Then we make use of “Iodine Titration”(immersion method) and “Opposite Voltage”(floating method) to seek for the best conditions of adsorption the metallic ion through polystyrene rubber. The former can effectively calculate the concentration of copper ion, but the procedures are quite complex. The greatest advantage of the “Opposite Voltage” method is that we may know when the adsorption of polystyrene rubber is saturated and should be regenerated. As far as we know at present, the conditions of obtaining the best effect that polystyrene may adsorb the cation ion are as follows: fine particles of polystyrene rubber; low concentration metallic solution; polystyrene rubber of which the mass is greater; at lower temperature, slower waste water flow speed and the copper ion waste water with pH 4.30; the adsorption effect of sodium type polystyrene rubber is better than the hydrogen type. Polystyrene rubber also has adsorption effect toward different metallic ion. The less ion per cubic contains, the higher the original opposite voltage. With the same mole concentration, different ion adsorption effects may range as follows: Cr3＋＞Fe3＋＞Ni2＋＞Cu2＋＞Co2＋. The batch adsorption definitely may erase metallic ion completely. By observing the adsorption isotherm, possibly because the polystyrene rubber is a multi-apertured matter, we find that it is impossible to judge exactly the adsorption model of those metallic ion solutions of which the concentrations are below 500ppm. Those which are over 1,000ppm belong to physical adsorption models. Polystyrene may be regenerated and get an adsorption effect by coating sand particals. In the last analysis, we may make paper clay and magnets of different styles by mixing the adsorbed metallic ion polystyrene rubber with calcium sulfate, paper pulp and a little lime(the mass are respectively 13g, 13g, 7g, and 0.04g). The reuse of waste is really very interesting.
神經妙算流博村-是洪水？是山崩？
南投溪頭米堤飯店在2001 年因土石流受創，產險公司以「土石流即是山崩」為由拒絕理賠。歷經5 年的訴訟後，2007 年1 月台灣高等法院認定，土石流屬保險契約中所規範的「洪水」，並非「山崩」，判決產險公司應給付賠償金。土石流究竟是洪水？是山崩？主要因素便是土石流發生的水文因子。本文藉由博愛村的現場調查及文獻探討先作初步資料分析（preliminary analysis），了解到地文因子(physiographical factor)是土石流發生的充分條件，非必要條件；一般僅考慮雨量因子，把地文因子看作常數（忽略地文因子受水文因子歷程(course)影響），簡單易懂，但在安全與經濟考量上有待討論。使用類神經網路對已發生過的土石流事件計算土石流發生臨界曲線，並使用模糊理論計算松鶴地區其受水文因子影響的土石流發生臨界曲線，這樣的模式，考慮似乎比較周到。由「米堤飯店」的例證，更說明土石流發生的水文因子的必要性。Lemidi hotel, Xitou, Nantou because mudflows and landslides and was wounded in 2001. The Insurance Company refused to settle a claim on the position on “A landside is a debris flow”. After the lawsuit which was going through 5 years. In January, 2007, the High Court of Taiwan asserted that the adversity in the 2001 belongs to “the flood” in the norm of the insurance agreement. As the norm of the insurance agreement said, the debris flows in the land is the flood, not the “landslide”. The High Court of Taiwan judged that the Insurance Company should compensate the Lemidi Hotel. Is debris low a landslide or a flood? The main cause is the Hydrology in the happening of a debris flow. We did preliminary analysis of forms by on-the-spot investigation on Song-Ho Village and reference discussing. We realized that physiographical factor is an abundant condition for a happening of a debris flow, not the essential condition. Generally, people only consider rainfall factor. And they consider physiographical factor as not as constant (neglect the influence of hydrology factor to physiographical factor). We can understand easily in that way. Therefore, in the aspect of security and economy, there is much doubt that is needed to be discussed. People who use neural network method to calculate the curve of the debris flow happening , and used fuzzy theory to calculate the curve of the debris flow happening which is influenced by the hydrology in Song-Ho Village. In that way, we may consider more thoughtful. From the example of the Lemidi Hotel in Nantou, we can prove that how necessary the hydrology factor in the debris flow is.
應用垂直循環層流淨化水質之研究
The results of the thermal diffusion experimental show that the separation efficient\r increases with increasing ΔT, but decreases with increasing Q at C0 constant. When\r Q is kept constant, the efficient of change ΔT are small, and the maximum at C0 about\r 545 mg/L. The purification efficient of raw water for thermal diffusion is low.\r And it is high energy consumption, difficult operation, and high costs. So the potential\r of the application is low. Therefore, the vertical circulatory laminar flow apparatus\r was developed in this study. And the separation equation of this apparatus was also\r set up. The results of vertical circulatory laminar flow experimental show that\r the efficient increase with increasing V, and the optimum conditions are at about\r Q= 1.05 L/min, C0=800±50 mg/L, and V=26 cm/min. The separation efficient of the\r vertical circulatory laminar flow apparatus is higher than thermal diffusion apparatus.\r And its energy consumption and costs are low, and easy to operate. Since all interior\r moveable plates have two operation sides, so the multiple channel apparatus is application.\r Therefore, the multiple channel apparatus can treat large amount raw water and has\r low costs. The efficient of the experimental all are better than the theoretical\r values that may due to: (1)the assumed partical diameter is too small,(2)the flow\r is not real laminar flow, and (3)the end-side effect is not considerate.
\r 熱擴散實驗結果顯示在固定C0下，分離成效隨ΔT增加而增高，但隨進料流率增加而降低。在固定ΔT下，分離效率亦隨進料流率增加而降低。固定進料流率下，增加ΔT對分離效果的影響不大，以C0=545±10\r mg/L時，顯現出最佳成效。採用熱擴散裝置雖對降低原水中之懸浮微粒含量效果有限，且能源需求高，造成高成本和操作複雜，不具實用潛力。為提高分離原水微粒之成率，以及簡化操作與降低成本，本研究開發垂直旋轉帶裝置來製造出上下循環水流，並導出水流與微粒於其中之流速分布式，以及頂部、底部出口之微粒濃度計算式。垂直循環轉帶實驗結果，顯示提高V值有助於降低Ct/Cb比值；Q=\r 1.05 L/min左右、C0=800±50 mg/L下與V在26 cm/min左右，均有較低之Ct/Cb比值。垂直旋轉帶裝置分離成效明顯優於熱擴散裝置，且設備簡單、能源需求低與操作容易。由於旋轉帶之兩面均可以做為移動平板，因此不僅可以用來處理大量之高濁度原水，也能更具經濟效益。由理論與實驗結果之比較，顯示理論成效較實驗差，探討其原因可能是：(1)平均粒徑之假設值偏低、(2)流場並非全然以層流流動、(3)兩端終端效應未加考慮等。
線蟲捕捉菌Arthrobotrys musiformis 調控捕捉網之分化及其黏液之基因之選殖和特性界定
Nematophagous fungi can form different kind of trapping device to trap the nematodes when they show off. They may play a role for control of the plant and animal parasitic nematodes as an alterative choice beside regular practice. We attempt to investigate the adhesive’s attributes and the genes that encode trapping structures. Now we have already constructed the Arthrobotrys musiformis Fosmid library which will play a vital resource for specific genes analysis, cloning and characterization in the future. We have chosen two genes encoding protease and superoxide dismutase from Arthrobotrys musiformis, respectively, and will be used as probes to screen the Fosmid library. The relevent clone(s) will be subject to restrictive enzyme disection, Southern blotting or even whole Fosmid 40kb DNA fragment sequencing to discover the interesting and paramount genes. 線蟲捕捉菌在線蟲出現時可以產生型態各異的捕捉構造，捕捉或黏著線蟲。它是防治線蟲的另類選擇。本實驗是由生物的分生觀點切入，希望能夠了解線蟲捕捉菌Arthroborys musiformis於捕捉網表面之黏液生化特性以及控制產生捕捉構造的基因。目前已完成建 Arthrobotrys musiformis之Fosmid library，並且選擇兩組探針：蛋白質?(protease)以及超歧氧化?(superoxide dismutase)，將以PCR進行基因探針之DIG標定，之後篩檢Fosmid library，選殖出相關clone，進行限制?切割，南方氏雜合特性分析或40kbDNA全序列分析，尋找相關基因以利下游實驗工作之進行。
