高分子發光二極體乃是利用電子和電洞在發光工作層結合而形成激子，激子在形成後隨即以光的形式衰退，而發出光來。一般而言，高分子發光二極體是一種三明治的形式，電子注入層/發光工作層(高分子)/電動注入層，而通常我們會選擇加入電子傳遞層和電動傳遞層，來增加其發光效果。本研究係針對聚苯胺做為電洞傳遞層對發光二極體之影響，分別對有電洞傳遞曾和無電洞傳遞層之發光二極體作導電度測量、循環伏安法、電位-電流測量、亮度-電位測量。發光二極體中所須之高分子層，須利用旋轉塗佈機，將其均勻的披覆在載體上，由於本校並無此儀器，所以將離心機改造成簡易旋轉塗佈機，並觀察其披附之效果。另外，在封裝元件時，係因學校缺乏真空蒸鍍的儀器，所以將利用電鍍法把鋅鍍在ITO玻璃上，或將鋁片和ITO玻璃緊靠在一起，針對此二替代方法，本研究將探討其所製出原件成效。Polymer light emitting diode (PLED) utilizes the energy gap between the layer of electron and electric hole that emits the light due to the decay of solitron. PLED is always in the sandwich from, that means the conducting polymer is contained between metal as an cathode and indium tin oxide as an anode. It is used the addition of another electric transfer layer and electric hole transfer layer to improve the lighting efficiency of PLED. The purposes of this study are to discuss the effect of polyaniline as the electric hole transfer layer. The study methods are conductivity measure, the cyclic voltametry, the luminance-voltage curve. The simplified spin coating machine was designed to coat the polymer onto the ITO. The zinc was electroplated onto the graphite as an cathode.

我一直在想，為什麼植物的美麗不能永恆呢？美麗的花朵，伴隨答淡雅的香氣，往往能美化環境，更能淨化人心，自小生長在鄉間的我，更能感受到這份來自花草的神奇力量，因此深深愛上這花草世界．但為何花朵的美麗總是短暫，為了想讓植物開花的時間長久，於是，我著手進行在自然科技雜誌及網路上搜尋相關的資料及訊息，但是找到的大多都是使生長速率變快的報告，卻找不到使生長速率變慢的報告。終於，曾經有人運用圓周運動的原理，而成功的使動物的生長速率變慢，於是，我針對直線運動及圓周運動分別依速度快及速度慢來分成四組，以及一組靜止狀態的綠豆，將五組實驗後的數據相互作比較，結果發現，除了陽光、水、空氣、土壤、養分及本身具有的胚胎外，在不同的運動狀態下也會影響到植物的生長速率 ·I was thinking about the reason why the beauty of plants couldn’t last forever. The beauty of flowers that accompanied with sweet-smelling could beautify the landscapes and purify our heart. I felt strongly about the magic power of the plant because I lived in the country in my childhood. Therefore, I loved plants deeply. Why was the beauty of flowers transient? As a result. I started to search for the related data and information on science and technology magazines and Internet. Most of the reports increase the growth rate of plants, but I cou1dn find the reports about slowing down the growth rate.At last, someone had successfully used the principle of circumference movement to slow down the growth rate of animals. Therefore, I focused on linear and circumference movement and divided them into four groups and one group of green beans with still state. I compared the data of five groups, and found that different movement affected the growth rate of plants m addition to sun, water, air, soil, and embryo.

IPNV 已是世界性分布的魚類病原體，其感染對象以鮭魚、?魚為主，但也在其他魚類分離出來，如鰻魚、吳郭魚、梭子魚、鱈魚、鱸魚、文蛤、泥鰍、虱目魚、香魚、金龍、石斑、等中皆曾發現IPNV之感染。足見此病毒廣泛地存在於魚貝類，常造成經濟魚貝類的重大損失。感染性胰臟壞死病毒之致病株，可造成魚類急性感染，而大量死亡。非致病株 ，不會造成大量死亡。國科會整合計劃之一其研究結果顯示，非致病株IPNV感染石斑魚死亡率只有10%，若病毒與重金屬同時存在時，會有55~92%死亡率; 在弧菌(Vibrio)與IPNV混合感染，亦有相似結果，此說明單一病毒感染魚貝類或單一環境因子，都不會造成大量死亡，但病毒和環境因子加在一起，引發大量死亡。所以對IPNV的防治是很重要的，所以針對病毒基因加以研究，IPNV是一種兩段雙股核糖核酸病毒，複製是在其細胞內的，但其團譯出的VP3中，已經證明與雙祋核糖核酸結合有關。近發現Michelle Donnelly及Gillain Elliott 的研究論文"Nuclear Localiziont and Shuttling of Herpes Simplex Virus Tegumnet Pretin"中，證明了HSV病毒所轉譯出的蛋白質VP13及VP14中，密集出現精胺酸(Arginine)的地方具有能將蛋白質帶入細胞核內的功能，而攜出細胞核的序列則有斷續的白胺酸(Leucine)出現。我們發現了傳染性胰臟壞死病毒(IPNV)病毒的轉譯出的VP3中也有能將蛋白質帶入或帶出細胞核的按基酸序列，故欲利用實驗證明是否有類似將蛋白質送進及送出的訊息，以便進一步探討VP3是否進入細胞核直接調控細胞核的某些功能。

This research introduces a new, more efficient method of age determination for eclipsing Binary through use of celestial Positioning . Statistical Analysis of x-y plots of eclipsing Binary Stars within our, Milky Way Galaxy were conducted in order to find the standard deviation of each eclipsing binary star’s distance from the celestial equator. Before the standard deviations could be considered for comparison, the medians from each of the three s-y plots were examined. There medians had to show a value close to zero in order for the standard deviations to be relevant. A value close to zero indicates a proportional and symmetrical plot with an equal distribution of stars on each side of the plot. All three plots generated indicted a median no greater than 1/100 in distance from the celestial equator. A low standard deviation indicates young relative age. The statictical analysis calculated standard deviations of 2.41 for W Ursae Majoris, 1.77 for Algol, and 1.20 for Deta Lyrae. The statistical analyses were then compared to the previously made visual and mathematical analyses conducted in previous years’ studies. All analyses conducted conclude that W Ursae Majoris is the oldest type and Beta Lyrae is the youngest type of eclipsing binary star. This method can be implemented to greatly reduce time in studying the relative ages of individual objects and types of objects within our Milky Way Galaxy.

In this project, the stem of the banana tree is innovated into the absorbent substance in the baby’s diapers. A water proof material too has been innovated . In the study carried out, several changes has been identified in the production of an environment friendly disposable diapers.The structure of water molecules and cellulose as well as charges in both materials will enable cellulose present in all green plants to absorb water easily and effectively. Cellulose is also insoluble in water or solvent. This project uses the banana stem due to its high cellulose content and furthermore the cellulose present has a very fine structure which will increase its absorbency rate. Baby’s urine will be absorb into the absorbent material through capillary actions due to surface tension that develops between the cellulose and baby’s urine. The absorbent substance in baby’s diapers available today in the market is made up of Polyacrilate (SAP) and cellulose which are extracted from hardwoods, particularly pine trees. The production of the absorbent substance from the cellulose will help to reduce the logging of hardwoods.

To measure the air quality of the city of Prince George by using lichen as bio-indicators of pollution.

It is used by practically everyone that has vehicle. The device checks your spare wheel and wams you when it is going flat.

This scientific research project “Tharn Din - Alternative Energy Source of the Future” is directed toward producing a new type of soil charcoal. Tharn Din, with excellent combustibility. The experiments were divided into six steps. First, we selected soils of exceptional adhesion property Next, we looked into many different combustible materials for soil admixtures. Many different formulas of soils and admixtures were tested. The most promising formulas were then optimized for maximum combustibility. After which, the best formula was chosen and we further optimized its combustibility. Combustion and ignition rate and characteristics of this formula were investigated. And lastly the effect of surface area on combustible rate was examined. It was found that mud was the best adhesive and wood chip was the best admixture. Tharn Din made of one part of mud and 3 parts of wood chips released higher thermal energy than normal charcoals. We found that a special type of Thai soil, Din See-eaw, when mixed with wood chips created Tharn Din of exceptional combustibi1it Ignition and combustible rates are proportional to the surface area of Tharn Din.

Miracles in life originate from daily life itself. What can be imagined can really be achieved. Hong Kong, as an international city, is small in area and densely populated. To utilize space, tall buildings inevitably emerge. Taking elevators has therefore become the daily routine of everyone of us. However, problems abound with the present elevator system. You have probably gone through the dreadful episode of waiting long for an elevator to come, and passage being interrupted by unreasonably frequent stops. Besides, it wastes space, since each elevator tube can only accommodate one elevator. This is why our Free-D Elevator System will revolutionize the present one. It consists of a large cylindrical tube, which can be divided into several smaller, imaginary sector-shaped tubes. In each small tube a large number of elevators move vertically by magnetic levitation. The elevators can also rotate from one tube to another, thereby avoiding collision. This innovative design will substantially increase the number of available elevators for given space. Most importantly, it is highly feasible.

It is used by pigeon owners, farmers and squatters. The machine peels thesunflower seeds and leaves them separate from each other. The seeds can be used for pigeons,birds and making of flour. The shells of the seeds can be used as compost and ferilizer. This is an eco-friendly system.
