「天上掉下來的禮物嗎?」--討論近十年來大陸沙塵暴對台灣之影響與變化趨?
In recent years, sandstorms have seriously attacked Taiwan day by day. Combining with the observations of Central Weather Bureau and the satellite images of NASA, the study has been collected the data of suspension grain in decades. And the study hopes the sandstorms’ information could be observed in early period. Still it hopes to find out the possible transmission paths in the atmosphere. Then we know how to cope with sandstorms in early time. Sandstorms attack Taiwan frequently in alternation of the spring, the autumn, and the winter. Compared with thecharts of sandstorms and the satellite images, we could broadly aware hat the moving paths of sandstorms are related to the currents and the characteristics of the atmosphere. When El Nino happens, the times of sandstorms attacking Taiwan decrease, and that increase when La Lina happens. From the observation data of acid rain, when sandstorms attack Taiwan, acid rain would diminish. Combining actual Measures and satellite data in the future, maybe we can establish a prediction mechanism of sandstorms.近年來，大陸沙塵暴侵襲台灣的情況日趨嚴重影響。本研究中收集了近十年來懸浮顆粒資料，配合中央氣象局所觀測的資料與美國太空總署的衛星影像資料，希望能夠在早期觀測發現大陸地區沙塵暴訊息，和沙塵暴所帶至大氣中的懸浮顆粒可能傳輸的路徑期能早期應映。發生沙塵暴侵臺事件的季節，主要在秋冬及冬春兩季交替期間發生的次數為最多。由沙塵暴監測氣候圖表及美國太空總署的衛星影像進行綜合比對之後，可大致瞭解大陸沙塵可能的移動路徑與大氣環流及特徵有關。聖嬰現象（El Nino）發生時，侵襲臺灣的沙塵暴次數會減少。在「反聖嬰現象」（La Lina）發生時，侵襲臺灣的次數相對增加。由酸雨中得知大陸沙 塵暴侵襲台灣時，酸雨情況會減緩。未來結合實測及衛星資料或許我們可以預報大陸沙塵暴的侵襲。
太陽能發電環境評估與追蹤器探討
本研究首先探討台灣各地的日照時數與世界重要都市的比較，發現台灣南部日照時數皆超過2000 小時，適合發展太陽能。接著，?了增加陽光的能量密度而加設弗瑞奈透鏡，雖然能順利的使照度放大三百餘倍，但歲日照角度的影響甚鉅，?了克服角度的問題，我們決定開發自製的追蹤器來改善角度的問題。太陽能板需要改變仰角跟傾角（雙軸調整），由光感應器判斷及自動控制程式，判斷隨時辰與季節變化的太陽角度。當搭配奈米塗料、弗瑞奈透鏡與追蹤器，總輸出功率可增加約50%。太陽電池表面玻璃會阻擋藍紫光的吸收，但本研究在太陽能板上塗佈奈米塗料，發現能增加短波長的吸收；經實驗後奈米等級表面具有自潔效應，可防止灰塵雨滴的堆積影響光線吸收，具有開發價值。This project first compares Taiwanese locations with other places in the world on average daylight times. It was discovered that southern Taiwan has the longest average daylight time all over 2000 hour sand therefore most ripe for solar power development. To increase the energy density of solar Fresnel lenses were incorporated. Although this has the advantage of magnifying illumination by three hundred percent, the alignment angle for the solar panel will have a significant impact on performance. We then designed and built a automated tracking device with illumination sensors to control the elevation and inclination of the solar panel which adjusts the angle according to environmental conditions such as time of day and season. When solar cell collocate Nano coating, Fresnel lens, tracking device, its power can promote almost150%. The glasses on the solar cell will interfere solar cell absorbing blue and purple light, but we lay on a Nano coating and we find Nano coating can improve solar cell to absorb short wave; and surface o Nano have lotus effect, it can prevent dust and rain effecting solar cell absorb lights, and it is worth developing .
紫蝶幻影
The main purpose of this experiment is to discuss the characteristics of iridescent colors of Taiwanese Euploea’s wings, inclusive of the relations between the colors of wings and squamas. According to the results from scanning electron microscope, we discovered that the iridescent colors had a close relation to nanostructure and arrangements of squamas. We inferred that both the nanostructure and the arrangements would influence the formation of iridescent colors and the basic colors on wings. In addition, the basic colors on wings are related to different types of scales. To compare with the diverse formations of different sorts of Taiwanese Euploea’s wings, we took SEM pictures of Elymnias hypermnestra as well, discovering that its iridescent colors had similar relation with scales. And there was the regulation that Elymnias hypermnestra had only one type of scales at iridescent area, and two different scales at not-iridescent area as well as Euploea’s. 本實驗目的為探討台灣地區紫斑蝶蝴蝶翅膀幻色的特性，以及翅膀幻色與鱗片的相關性。由結果得知，幻色實驗中利用掃描式電子顯微鏡發現紫斑蝶幻色的形成和其鱗片的細微結構與排列方式有密切相關。我們推論紫斑蝶的鱗片細微結構與排列皆會影響其幻色的形成，而顏色的不同則與不同類型的鱗片相關。除此之外，我們亦對同具幻色的紫蛇目碟進行拍照分析，發現其幻色亦與鱗片有相關性。紫蛇目蝶的幻色區具有單一種鱗片構成的規則性，非幻色區則有兩種鱗片，與紫斑蝶相同。
以珊瑚蛋白及光頻轉換分子改善太陽能電池效率之研究
能源危機日益嚴重，開發再生能源成為當務之急。在諸多的再生能源之中，太陽能最易於使用，且可源源不絕的不斷取得利用。但目前太陽能電池的效率始終不高。其中重要的原因是太陽本身的頻譜多為短波長，並不適合絕大部分頻譜響應較佳，多為長波長的太陽能電池。目前改善效率方式，多為改變太陽能電池的頻譜響應以配合太陽之頻譜。本研究提出反向思考的概念，藉由頻譜轉換的方法，改變照射在太陽能電池上的太陽光頻譜，以提升太陽能電池的效率。本研究利用一種珊瑚礁的螢光蛋白質（DsRed）以及人工合成的螢光染料（Cy-5）最為本研究的頻譜轉換的材料，加於低成本，目前市場佔有率較大的單晶矽太陽能電池上，經由理論與實驗的結果顯示，增加的發電效率約為3~5%，證實利用頻譜轉換的概念確實可以提升太陽能電池的效率。Energy crisis has become more and more serious in recent years, which makes recycled-energy development is a must. Among different recycled energies, solar power has two advantages, that is, easy-to-use and endless supply. However, the conventional solar cell makes poor use of the solar spectrum because the solar spectrum is mainly composed of short-wavelength, which can’t fit to most of solar cells which is more sensitive to long-wavelength. Currently, the major method to improve the efficiency is change the function of spectral response, such as concentration lens, tracking devices, and antireflection coating. Up to now, no one notices the possibility of changing solar spectrum yet. This research provides an insight into this issue. Instead of changing the function of spectral response, I changed the solar spectrum, which irradiates solar cells through spectrum conversion to improve solar cells’ efficiency. This research uses one kind of coral fluorescence proteins (DsRed) and one kind of artificial fluorescence dyes (Cy-5) as the materials of spectrum conversion. Then coat them on the low-cost and high-market-share mono-crystal-Si. According to the theories I researched and my experiments, the improvement of the efficiency is about 3~5%, which proves it is actually useful to elevate the efficiency of solar cells through spectrum conversion.
緩步門的木乃伊-會蟄伏的熊蟲
The study is to investigate Taiwanese tardigrades,and the research of that is few. Tardigrades are commonly called water bears and have been identified more than 750 species. Limno-terrestrial tardigrades are small, 0.2-0.5 mm in length, and mostly found in moss cushions growing on rocks, soil, or the wall of houses. When the environment dehydrates in dry weather, Tardigrades desiccate into a reversible state of metabolic suspension called cryptobiosis. We have been finding a number of tardigrades in moss at many places in Taoyuan country. First, we put the moss on the dissected microscope to seek for tardigrades, and then placed it on the microscope for photographing and observing. The study is mainly focus on Taiwanese tardigrades. we have classified 11 Taiwanese species in four families（Echiniscidae,Calohypsibiidae,Milnesiidae and Macrobiotidae）, making Chinese keys of classification. From the habitat envoriment, the species, the density and the diversity we survey as well as the most suitable pH envoriment we experiment, we approach the relationship between the distribution of tardigrades and their habitat. Besides, we also research lots of conditions which bring cryptobiosis and make culture medium in order to inspect its living. These results indicate that tardigrades desiccate into cryptobiosis in ten munites in acid rain(pH4.65). From outdoor surveys, we have noticed tardigrades can’t be found in the moss right next to road.The length of each family is: Calohypsibiidae＞Milnesiidae Milnesium＞Macrobiotidae＞Echiniscidae. 此研究是探討台灣熊蟲，而有關台灣熊蟲的文獻資料極少。熊蟲屬於緩步門，體長約 0.2-0.5 mm，熊蟲在不利的環境會蟄伏，環境有利時又會膨脹而復甦，而其構造系統不因此而破壞。 我們在桃園縣多處的苔蘚發現熊蟲，我們先將採集的苔蘚放至解剖顯微鏡下尋找熊蟲，再由複式顯微鏡觀察構造並拍照紀錄。研究主要是探討台灣本地的熊蟲，我們已分類出十一種台灣熊蟲，製作中文檢索表。藉由觀測採集環境和所測的密度、歧異度和種類，及實驗出其最適宜的 pH值，探討環境對其分布的影響。也探討各種因素與蟄伏的關係，製作培養基以觀測其生活史。研究結果顯示：1.已經分類出台灣有緩步門四科（端爪科、Calohypsibiidae科、Milnesiidae科和 Macrobiotidae科）十一種熊蟲。2. 污染嚴重或環境髒亂的地方，不會有熊蟲的存在，且熊蟲有群居性。3. 端爪科(棕色)熊蟲在 pH4.65（台灣都會區雨的酸鹼值）以下的液體環境活動力明顯降低。4.熊蟲多分布在高溼度（87.5~90.4％）的地方，不分布在中低溼度 （76％以下） 的地區。5. 各科的體長為 Calohypsibiidae科＞Milnesiidae科 Milnesium屬＞Macrobiotidae科＞端爪科。
Is the fruit safe?-吊白塊的簡易自製試劑
吊白塊是一種在現切水果中常見的食品添加物，它可使剛切的水果不易被氧化，並同時具有漂白的效果，但此種添加物會對人體造成許多疾病。本研究針對吊白塊作嘗試性的初級檢驗，選用一般常見的氧化劑和染料，自行研發簡易的檢驗方法，且進一步製作安定性佳且攜帶方便的試紙。本實驗結果發現，由衛生局提供的「藍吊試劑」本身不甚穩定，且顏色變化不明顯；在自製檢驗試劑方面，效果最佳的是過錳酸鉀，濃度可測至0.0005M，且反應相當快速，唯試液容易與水果表面的Fe(II)離子反應；孔雀綠和晶紅酸等染料效果亦佳，且變色相當明顯，但反應時間較長。Rongalit is a bleaching agent commonly used as a food additive. It can prevent fresh fruits to be oxidized (without color-changed), especially when they were cut for sale. However, as for this additive, it is not good on health and is necessary to be detected. The test-paper currently used, the so-called “blue-test paper”, can be obtained from the Department of Health (Taipei). However, its stability is poor; the color change is not clear when it reacts with Rongalit. For this reason, I developed simple methods for detecting Rongalit by using various oxidizers and dyes. A test-paper, with better stability and easily for carry, was successfully developed. The findings show that the use of KMnO4 on the homemade test-paper provides the best result. The reaction time is short and the limit of detection can be improved to 5 × 10-4 M. The color changes were also clear when malachite green and fuchsin acid were used, but the reaction times were longer.
液態導體的磁效應
本文所探討的議題為電解質溶滿通以電流後所產生的效應與機制。本實驗所採用的方法為電解與電鍍，運用這兩種方法，來比較電解液在不同狀況下所產生的結果；經過多次的實驗，累積了許多實驗結果，使我們可以得到更精確的數據 · 在此次實驗中，我們發現電解液在相同的電壓下，通以電流後的穩定性與金屬的活性有關，活性越大越不穩定；反之，活性越小越穩定。另一個發現為，只有單一極性離子移動的情形，可通過的電流，比陰陽離 r 同時移動時為大；但因通過的電流大使電解液反應劇烈，產物時時覆蓋電極使電流下降。所以就穩定性來說，是以陰陽離子同時移動為佳 · 在展望方面，希望可以發展到液態磁屏避的設備，可減少設備過重之問題 ·This is a study of how electric current effects the electrolyte solution. The experiment was conducted through two methods: electrolysis and electroplating, the results of which were compared. The experiment of the same designs hi been conducted repeatedly and, as a result, accurate data were collected and accumulated.One of the two major findings from the experiments was that, when under the same voltage, stability of the electric current varied with the change of activity of the metals; the greater the activity of the metals, the less stability of the current, and vice versa. The other major finding was that, with the movement of dipole-ion, a greater amount of current would go through the solution than that which would go through with the movement of cathode and anode; however, the greater amount of current would cause intense reaction of electrolyte solution, hence merging the electrode and reducing the current. So as long as stability is concerned, the movement of cathode and anode is preferable.It is hoped that more sophisticated experiments designed on the basis of the similar principles will eventually lead to the construction of equipment of liquid-magnetic shielding of smaller weight and size.
會旋轉的電解液
本研究主要探討電解液之帶電離子在磁場中的動力行為。為了觀察更細微的結果，共歷經三代裝置改良，第一代用五個電錶及探針測量徑向橫截面上五點的電壓，所測數值電壓有下降趨勢但不足以呈現細微部份的變化。第二代利用電壓感應線、搭配平移台及電腦，呈現連續性且經數位處理之結果，出現電壓升降的電荷堆積現象。第三代為了更精確，將裝置結構及器材上改良。觀察到在磁場作用下有旋轉現象，改變電極極性時，會有順逆時鐘方向的改變，且只有電解質液才會有旋轉。更可以使用帶電質點受到勞倫茲力F=q(VxB)理論解釋。且旋轉中的電解液比沒有旋轉時，析出的銅量少，反應溫度升高快，電解液內電壓分布因電荷堆積造成的高低起伏。經過改變磁場強度、電解液濃度，不銅價離子電解液，結果濃度大、磁場大、離子數較多者，呈現電壓分布圖快速變化，彎曲大。This thesis report is the study of combining the moving charged particles under the perpendicular magnetic field. By using the theory of moving and electrolysis, the electrolytic liquid will swirl through the particular arrangement of the horizontal cylinders enclosed in a circular enclosure container and strong magnet. Then, the researcher observes the force situation of the charge in the magnetic field and discusses the differences of the electrolysis effect, which is experimented under the different conditions, such as, in the magnetic field or no-magnetic field. Furthermore, the researchers discuss the conduction of voltage spreading and interfering when the moving electrons under different position of two electrodes and under the different interaction of electric field and the magnetic field. And the changing reason as follow: （1）the magnetic field strength. （2）the concentration of the electrolytic liquid. （3）electrolytic solution.
