讓瓶塞隨心所欲
這是一種可在膨脹狀態及未膨脹狀態間轉換的膨脹收縮瓶塞。本設計之瓶塞包含一彈性橡膠之塞座及一剛性塑膠之旋轉控座。該瓶塞在未膨脹狀態，可將瓶塞置於平口內將瓶塞順時針方向旋轉90度使瓶塞由未膨脹狀態轉換至膨脹狀態將瓶子密封；欲開瓶時將瓶塞逆時針方向旋轉約90度使瓶塞由膨脹狀態轉換至未膨脹狀態，可輕易將瓶塞從瓶子內拉出。根據顧客之需求設計瓶塞並選定適當之塑膠材料以製作旋轉控座及適當之衛生橡膠以製作塞座，依廠商提供塑膠及衛生橡膠之特性資料做有限元素分析預測橡膠元件受撐大之變形量，進行加工與製造印證分析之結果，與預期目標有相當的差異，故製作簡易之試件進行探求塞座內縮量與瓶塞膨脹量之關係， 探求瓶塞膨脹量與瓶子所能承受的壓力之關係，進而逆向設計瓶塞之塞座內縮量。 This is a kind of bottle plug that can change at the situation of swell or unswell.The design of this bottle plug includes a rubber plug and a rigid plastic controller that can revolve around. We can put the bottle plug at the top of the bottle and rotate it 90° c.w., the bottle pug will be at the situation of swell and then seal up the bottle. If we want to open the bottle, we just rotate 90° c.c.w., and the bottle plug will be at the situation of unswell and then we can pull the bottle plug out easily. I design this bottle plug according to the need of the customers; choose the certain plastic material to make the rigid plastic controller, and the properly rubber to make the plug; analyze and predict the amount of deformation by Finite Element Method in accordance with the characteristics of rubber and plastic supplied by the factories. However, the result and the expected result are quite different. In order to solve the problem, I make an easy sample to search for the relationship between the contraction of the rubber plug and the swells of the plastic controller and also the relationship between the swells of the plastic controller and the pressure that the bottle can endures. Then I design the contraction of the rubber plug on the base of the result of the experiment I made above.
Geo Air
1. Purpose: The purpose of this project was to design a theoretical tempered-air system to be integrated into an existing heating system in a home equipped with an air-to-air heat pump. This was to overcome the cost and environmental challenges of heating in cold climates as well as provide an environmentally friendly air-conditioning system in the summer at little to no cost. 2. Procedure: In the winter of 2010 an underground high-density polyethylene (HDPE) pipe (10cm diameter, and 30.5m length) was buried 2.5m underground around the footings of a new residential project. A fan with a flow of 3.4m³/min was attached to the pipe outside, and used to push air underground through the pipe and into the house. The ambient and incoming air temperatures as well as the date and time were recorded daily using a temperature probe with an error margin of ±0.1ºC throughout the summer and winter seasons of 2011. This data was then plotted and analyzed. A number of options to best extract thermal energy for potential use for heating and cooling were examined. Design components were selected to create an air chamber for an air-to-air heat pump to increase its coefficient of performance (COP). 3. Data: Graph 1 Graph 2 Winter Graph (Graph 1): The blue line represents the outdoor ambient temperature and the orange line represents the temperature of the tempered air. These are both arranged chronologically. The grey lines represent one standard deviation on either side of the incoming temperatures. The ambient temperatures vary dramatically, while the incoming temperatures remain quite stable. The lowest recorded temperature was about -9.0ºC, at which point the temperature exiting from the underground pipe was about 10.5ºC. Summer Graph (Graph 2): With dramatically varying ambient temperatures, the temperature of the incoming air consistently stays between 11.1 and 16.2ºC. The highest recorded outdoor temperature was about 30.0ºC, while the incoming temperature at that point was about 15.5ºC. This cold air was used as air conditioning.

分散質的結構與張力
洗滌用的界面活性劑分散系，沾在吸管可吹成泡，沾在框上則生成特定形體的薄膜；兩種不同現象，依據各自的性質原理，分別設計為可測量的裝置，研討表面張力與濃度間的關係，發現『兩泡連通法』，測量的靈敏度較佳，並且；薄膜總面積法則會因為框的形不同，測得薄膜總面積與表面張力大小的變化趨勢不一樣，而且數據誤差都比『兩泡連通法』大。市售的洗劑有肥皂與合成清潔劑兩類，它們溶於水的分散系，表面張力與濃度大小的變化趨勢正好相反；肥皂的濃度愈大表面張力愈大，合成清潔劑的濃度愈小表面張力愈大。這種現象發生的原因，和分散質是否含苯環結構無關。用數位照相輔助毛細管上升法，觀測『兩泡連通法』標準液的張力與濃度關係，數據顯示兩泡連通法與毛細管上升法，兩者比較各種分散系張力與濃度大小的結果相同。因此，用『兩泡連通法』比較不同分散系張力大小是簡便生動的可行方法。The dispersion of surfactant used for the purpose of cleasing,if dipped on a blowpipe,can be blown into bubbles and,if dipped on a frame,will form a certain shape of membrane.For these two different situations,according to the principle of their quality,measuringdevices can be respectively designed to explore the relation of surfact tension to its concentrate.It is discovered that,with the measuring device of the Two Bubble Connection Method,the sensitivity measured is better;and that,because of the difference of the structures of the frames,the total area of the membrane and the change trend of the degree of the surface tension will also be different and the probable error of the measured digits is always larger and it is not easy to find regularity. For the two categories of dispersion,soaps on the market and synthesis detergent,when they are measured with the Two Bubble Connection Method about the relationship of their surface tension to the degree of their concentrate,the trend of change is exactly opposite.The surface tension and concentrate of the category of soap are in right proportion whereas,for synthesis detergent used for cleaning bowls and plater and washing clothes,when its concentrate is less,its surface tension is more intense.Based on the findings of this study,the concentrate and the change trend of the degree of tension have no connection with whether there is benzene structure in the solvent. With the Capillary Rise Method assisted by digital photography to observe the relation of the tension of standard solution to the concentrate,we have found that they totally correspond to the result measured with the Two Bubble Connection Method designed in this study.
Filtered Light Frequencies versus Pigment Frequencies
Purpose of the research Experiments were performed to determine if the frequencies of the colours of pigment differ from the frequencies of the colours of filtered light. The third experiment was performed to determine whether the different colours of filtered light have an influence on plant growth. Procedures Experiments I and II were performed in sunlight and the temperatures of different colours of paper, as well as a white paper underneath different colours of transparencies, were measured by means of an infrared thermometer. The Stefan-Boltzmann equation was used for calculations. Experiment III was performed by placing ten spinach seedlings under each of the Code 40 red, green, blue and black/white shade nets. The control, 10 spinach seedlings, had no Code 40 shade net covering. All these spinach seedlings were grown under similar conditions and harvested after 4 weeks. Data In Experiment I the yellow paper was the only colour that did not perform according to the sequence of the white light spectrum (ROYGBIV). The temperature of the different colours of paper determined the amount of energy that was re-emitted. In Experiment II it was determined that the primary colours red, green and blue, as well as yellow of the filtered light, performed according to the white light spectrum. In Experiment III the spinach plants underneath the blue shade net have the highest average fresh mass (g), as well as the largest average leaf area (cm2), while the spinach plants underneath the red shade net have the lowest average fresh mass (g), as well as the smallest average leaf area (cm2). Conclusions In Experiment I the primary colours of the white light spectrum are red, green and blue. When red and green are combined, yellow is obtained. Therefore the temperature of the yellow paper was lower than expected, because only blue light was absorbed, while red, green and yellow light were reflected. In Experiment II all the colours of the transparencies performed according to ROYGBIV. By comparing the amount of energy of the colours of pigment to the colours of the filtered white light spectrum, it became apparent that there is a difference between the frequencies of the colours of pigment and the frequencies of the colours of filtered white light spectrum.
A Zero Pollution Process That Convert Non-Biodegradable Plastic Waste Into Hydrocarbon Fuel
Non-biodegradable waste materials like discarded polybags, rubber bottles, broken buckets and sachet water bags constitute a serious environmental problem all over the world. Several steps have been taken to eliminate these waste materials. Burning of these non-biodegradable waste in an incineration only constitute environmental pollution as poisonous gases are release to the environment which are hazardous to lives. The purpose of developing this catalytic conversion of non-biodegradable waste material into fuel is to remove the problem non-biodegradable waste materials poses in its disposal as well as obtaining a precious end product that will supplement fuel supply. Dump side lands that would have been used for dumping waste is also reclaimed. The procedure and chemistry is from the fact that Non-biodegradable waste materials are composes of long chain hydrocarbon. Some are made of polymeric units like polythene. The materials are heated in a closed vessel with coal and a catalyst. Heating is done progressively until condensate from gaseous product is obtained. This condensate is wide range of liquid fuel (Diesel and petrol) including LPG ranges. Further separation processing will give pure product of the different fuel liquids. The Apparatus consist of a cylindrical cooking vessel heated by coal furnace or other heat source like LPG, the vessel is made of steal. The upper side of the vessel provide an outlet vent to connect condensing section/condenser which is required for the conversion of gaseous form of product into liquid state. The fuel produce can find it application in the following areas; Heating of kiln in the cement company, Heating of boilers and Domestic lighting.
