利用電化學合成P型半導體--碘化銅(CuI)光感測器的製作
碘化銅（CuI）為一種P型半導體，在一般文獻中大部分被用做催化劑，合成極為不易。我們利用一簡單電化學合成的方式，可將銅控制在一價銅( Cu?O )，如在有碘離子( I－ )的溶液中便形成CuI。在這研究中我們將所合成出之P 型半導體CuI 製成光感測器，在偵測不同光強時有良好的線性關係(r2=0.9961)。在光感測器的實驗中我們利用CuI 電極，讓它接受光照，使其電流產生光電流，如果能儲存其光電流能量，就可成為一太陽能電池，利用其原理，未來可以發展成為替代能源。 CuI is a kind of P type of semiconductor in the general literatures. Most of the CuI is use to catalyst. Except that, CuI is difficult to synthesis. We use a simple way of Electoctrochemistry complex to keep Cu?O under controlling. For example, in the I- solution, Cu becomes CuI. In the study, we make the synthesis P type of semiconductor to be light sensor. In different lightness, the procedure showed good linearity(r2=0.9961) In the light sensor, we use CuI pole to accept sunlight. Then the current will produce light current. If we could store the energy of light current, it will be a solar energy battery. When we apply the theory, it can develop to be substitute energy.\r
彩色數位影像資料庫檢索架構-以國立自然科學博物館為例
國立自然科學博物館推出《數位博物館》，內含大量生物圖鑑及豐富館藏文物之圖文資 料，無論用於資料查詢或提供進階研究資料皆有極大貢獻。但經使用後發現，其檢索架構仍 只提供關鍵字搜尋及分類瀏覽，無法精確檢索出欲查詢之資料，尚有改進之處。 於是針對現有之影像檢索系統，我們跳脫出傳統以文字為檢索之依據，而設計出一連串 之改進方案，如下： 1. IRHI 色調辨識影像檢索，針對色調相近之影像類群提供良好檢索架構。 2. IRCI 輪廓辨識影像檢索，針對輪廓相近之影像類群提供良好檢索架構。 3. IRHCI 色調暨輪廓辨識影像檢索，綜合前述兩種方法之優點所設計。 A while ago, the National Museum of Natural Science put forth the “Digital Museum,” which contains great amount of biological pictographs and abundant collections of textual as well as pictorial materials. This has contributed tremendously to information search and advanced research. However, after employing them, we come to discover that its retrieval paradigm only provides key-word search and categorization browse, without enabling us to precisely pick out the desired data. Thus, this paradigm leaves something to be desired. To make up for the insufficiency of the existing system, we have escaped from the concept of searching by texts. Instead, we have designed a series of improvements. They are as follows: 1. IRHI(Image Retrieval by Hue Identification): Providing a sound paradigm for the image groups composed of similar hues. 2. IRCI(Image Retrieval by Contour Identification): Providing a sound paradigm for image groups composed for similar contours. 3. IRHCI(Image Retrieval by Hue and Contour Identification): Combining the strengths of the above two paradigms.
鈦鈦相傳-以新穎水熱-化學電池法製備二氧化鈦
In our experiment, the novel hydrothermal-galvanic couple method is used to produce nanostructured TiO2 thin film. Compared with the traditional hydrothermal method, whose process is conducted under high temperature and high pressure, the hydrothermal-galvanic couple method is a thermally and electrochemically driven process. The titanium atom is gradually oxidized on the surface driven by potential difference, and eventually become nanostructured TiO2. The advantages of the hydrothermal-galvanic couple method are numerous： they are simple, environment-friendly and energy-saving. Experimental parameters include time, concentration and types of solution. The hydrothermal method is used for comparison. By the cross-section and surface pictures of Field-emission scanning electron microscopy (FE-SEM), we can clearly observe that there is obvious change on the titanium surface, along with increased thickness and altered surface structure. The film of hydrothermal-galvanic couple method is thicker than that of hydrothermal method. Thickness increases with time and concentration as well. Both the hydrophile and decomposition of methylene blue examination indicate that the product on the surface contains photocatalyst-like feature.我們利用新穎水熱-化學電池法製備奈米級二氧化鈦薄膜。相較於一般傳統水熱法高溫高壓的製程，水熱-化學電池法結合了熱能與化學電能，讓鈦原子在電位差的驅動下於表面逐步氧化，最終形成奈米級二氧化鈦粒子，具備簡易、環保、省能的優點。實驗參數包括時間、濃度、溶液種類，並以水熱法作為對照組。由FE-SEM 橫截面圖及表面圖可清楚看到鈦的表面有明顯變化，膜厚增加、表面結構改變；以水熱-化學電池法所得的薄膜明顯較水熱法厚，而其厚度隨著濃度及時間的增加也有增加的趨勢，由試片親水性測試與亞甲基藍吸光度測試，皆顯示試片的表面產物具有類似光觸媒的性質。
修正駕駛汽車習慣之省油案
修正汽車駕駛喜歡猛踩加油踏板之習慣,把一加油動作分解成多段階級式加油動作,使自動變速箱內扭力降低達到順利變換高速檔o 達到節約能源.減少污染.提高效率之目的。The oil-saving project by adjusting the driving habits To avoid the habit of easily step the pedal to speed up, we divide it into multi-step fuel-filling procedures. Therefore, they decrease the wristing strength of transistor inside auto speed-changing box and reach high-speed brake smoothly. As a result, it can save energy, reduce pollution and increase high efficiency.
一個也沒漏掉，一個正有理數的排序的研究
本文中我們探討一個有趣的數列。這個數列有一個非常特殊的性質：將數列相鄰兩項的前項當分子，後項當分母，所產生的分數數列，恰好會出現所有的正有理數。 這個特殊的性質表示，可以將正有理數按照這個方式作排序，這個排序將完全不同於常見的正有理數排序的方法。
(1). 在正有理數的排序的結構中，我們做出許多有關於此數列的定理。
(2). 用數學歸納法證明此分數數列涵蓋所有正有理數，且每一正有理數只出現過一次。
(3). 將數列分割後，利用試算表製成數列規則表，並整理出快速的方法將數列表達出來。
(4). 將an 數列排成“樹＂的模式，可更快速的把正有理數寫下來。
(5). 最後，設計出搜尋正有理數的演算法，解決在分數數列中第n個正有理數會是多少；以及正有理數會出現在數列中第幾項的問題。
Let’s discuss an interesting sequence. There is a very special quality in it. In this sequence, choose two numbers, which are close to each other, and suppose the first number as “member” while the second one as “denominator.” Then we can get a fraction sequence that includes all of the positive rational numbers! According to this special quality, we can arrange positive rational numbers by the following method. Then we can get a brand-new way of the arrangements.
(1). We can find many theorems about this sequence according to this special arrangement of the positive rational numbers.
(2). We can prove the rule that this fraction sequence includes all of the positive rational numbers by mathematical induction. Furthermore, every positive rational number appears only once.
(3). After dividing this sequence into several parts, we can get a sequence rule list by using trial balance and find a faster method to express the sequence.
(4). Arrange the an sequence by the tree model. By this way, we can get all of the positive rational numbers much faster.
(5). Finally, we can develop the operation method to solve the questions that what position would one positive rational number be in the sequence and what is the first, second, third or nth positive rational number of the sequence.
醇類凝膠的安定與老化及其結晶情形
在這篇報告中，特別針對了凝膠的機制去做探討，以許多的實驗數據，再輔以凝膠的基本定義，去臆測各種有關於凝膠的老化機制，並藉由其過程中推斷出一些有趣的性質： 1. 當膠體內水分含量不同，與凝結後的醇類膠體有相當的影響。 2. 凝膠老化後形成的結晶形狀，因凝膠溶質、溶液內互溶性的不同，形成了不同凝聚程度的絮聚現象。 3. 同種陰陽離子在不同碳數的醇類凝膠中，因為與水溶液的互溶性也有所不同，間接影響了凝膠的形成速度，這對於安定來說，包含了很大的意義存在。 4. 對於其老化的速度，會因其安定程度而有所影響。 5. 老化後的溶液內的陰陽離子濃度，會直接影響其再次安定與老化的情形。 In this report, we especially do the discussion to the mechanism of the gel. With a lot of experimental data and the basic definition of gel, we conjecture various kinds of aging mechanism about the gel, and infer some interesting problems from its course: 1. Moisture content in the gel effect the gel’s quality after alcohol condensed greatly. 2. Because of dissolving difference between the alcohol and the other substances, crystallization forms after the gel aged have formed different degrees phenomenon of gathered. 3. The same kind of negative and positive ion among the alcohol gel that have different carbon atoms. Because of dissolving difference between the ions and the solution, the ions influence forming speed of gel indirectly. To being stable of the gel, this phenomenon includes very great meaning. 4. Stable degree of the gel can influence its speed of aging. 5. The consistency of negative and positive ion in the aging solution of the gel can influence its stable and aging situation again directly.
