短暫高鹽刺激提升番茄果實品質
本研究透過對蕃茄施予短時間的不同高鹽份濃度刺激，觀察植株成長 情形並對果實進行品質測定，本研究對於品質之定義著重於總抗氧化能力、糖度及硬度的檢測。由實驗結果得知Na+、Cl-離子所造成的滲透壓差，確實有助於可溶性固形物及Na+、Cl-離子的累積，對於果實糖度及硬度上皆有顯著變化。但對於如何造成總抗氧化能力值的提升，在未來的研究中會再深入探討。We observe the germination of the tomatoes and assay "the quality" of the fruits in our research by giving plants short-range acridness of different high salinity. In this research, the definition of “quality” emphasizes the anti-oxidized ability, the brix, and the hardness. By the experimental result knew Na+ and Cl- ion creates the osmotic pressure, truly is helpful to the Soluble Solid Content and the Na+ and Cl- ion accumulation. Yet regarding by what the anti-oxidized ability promotes, we will treat in-depth in our intended research.
火災逃生指引系統
在台灣公共場合快速成長下，例如：大賣場、百貨公司、展覽會場，這些公共大型場合都有很好的消防設施，但始終有人葬身於火場？ 原因就是幾乎所有的人都不會去特別注意逃生平面圖，導致花太多的時間尋找出口，這樣生存機率就大大降低。火場裡面有太多的致命因素，像是：高溫的空氣，毒氣、濃煙…等，所以必須把握每一分每一秒。為了加快逃生速度，我們將所有的通道都設有導引警示器，逃生者只要順著導引警示器就可以安全到達出口。為了因應公共場合有龐大的人群，所以逃生路線不能只有一條，因此我們設計上是有多條路線，一、可以解決龐大人群，二、可以加快速度。;With the rapid growth of public places in Taiwan, evacuation system is of more and more importance. Actually, public places, such as hyper malls, department stores and exhibitions, are not without fire-fighting equipment, but why is that there are still people getting killed in a fire? The reason is that almost no one actually pays attention to the evacuation plans. As a result, it often takes too much time to find the exits, which lowers the possibility of survival. In a fire, there are usually too many fatal factors, which could lead to death, such as high temperature and heavy smoke; therefore time is precious when escaping from a fire. To fasten the speed of evacuation, we set guiding alarms in every passageway. By following the guiding alarms, people can get to the exits safely. Besides, owing to the huge amount of population in public places, there can’t be only one route out. With regard to this, we design many routes in order to enable and fasten the speed of evacuation of huge amount of population.
數位攝譜儀及其數位分析方法
Color is not a physical quantity, but it is a characteristic of spectra. Traditionally spectra of light sources are characterized by the wavelengths and intensities of the spectral lines. We propose an alternative way of charactering spectra using colors. Using digital cameras, convex lens, and a 600 Lines/mm grating, we design a “Digital Spectrophotometer” (Pic.1), which uses no light sensors and electrical circuits that are necessary for conventional spectrometers. To analyze a spectrum using the “Digital Spectrophotometer”, we take digital images of the diffracted light through the grating emitted by the light source and then analyze the intensity distribution of the color components of the spectral lines. The structure of the “Digital Spectrophotometer” is simple and is easy to operate. The Digital Spectrophotometer includes a computer software program we have developed called the “Digital Spectrological Method”. After enlarging the digital spectrographs to a mosaic scale and regards each mosaic as a basic color block, the Digital Spectrological Method will transform every color block into a four dimensional “color coordinates” (λ (wavelength), R(red), G(green), B(blue)), where the coordinateλ is translated from the spatial position of the spectral line and the R, G, and B coordinates specifies respectively the corresponding intensity of the red, green, and blue color components. Comparing the “color coordinates” of the unknown light sources to the known, we can easily identify the wavelengths of the lights emitted by the unknown illuminant precisely. We have accomplished the following experiments by using the “Digital Spectrophotometer”: 1. Measure the spectra of various gaseous atoms, and establish the “database of digital spectra in color coordinates” (DDSCC). 2. Compare the characters of color presentation between digital camera images and positive film of the optical camera. 3. Identify the absorption spectrum of the Solar spectrum (Fraunhofer Lines) using the DDSCC. 4. Analyze the Orion αandβ spectrum using the DDSCC. 5. Identify the 589.0 and 589.6 nm wavelength difference between the “Double Lines of sodium spectrum”. 6. Measure the range of wavelength of the colored LED and register the results into the (λ, R, G, B) coordinates. 7. Compare the range of wavelength of He-Ne Laser and commercial Laser pointer. 8. Measure the Zeeman splitting of the hydrogen atom spectrum at 0.5 Tesla.
顏色雖不是物理量，卻是光譜的特性，傳統上對光譜的分析只記錄波長及對應的強度，而非以顏色來區分。我們運用數位相機、凸透鏡及600 條/㎜光柵，設計一個以顏色成分為標準來分析各類光譜的「數位攝譜儀」(Pic.1)。這個新的設計無須使用傳統光譜儀所需之光感應器及電路設計，只需拍攝光源透過光柵的繞射影像即可分析對應之光譜。我們製作的「數位攝譜儀」包含了一個自行設計的電腦軟體程式「數位光譜分析法」；將拍攝到光譜數位影像放大成「馬賽克」，作為光譜的最小「色塊」，該程式可將每個色塊轉換為一組四維的「顏色座標」 (λ (波長)，R(紅)，G(綠)，B(藍))，其中的λ 座標係由光譜線的位置轉換而來，而紅、綠、藍座標則記錄對應的紅、綠、藍色成分強度。與已知光源譜線的「顏色座標」比較，「數位攝譜儀」可精確測量各種未知光源放射出的光波波長且操作方便。利用「數位攝譜儀」的數位分析方法，我們完成以下實驗：1. 測量不同種類的原子光譜，建立「數位光譜資料庫」，包括氫、汞及鈉原子。2. 比較數位相機影像與光學相機正片的色彩顯影。3. 利用「數位光譜資料庫」，鑑定太陽光譜中的吸收光譜(Fraunhofer Lines)。4. 利用「數位光譜資料庫」，分析獵戶座α、β的可見光光譜。5. 鑑別波長589.0、589.6 奈米的鈉雙線。6. 用顏色座標(λ,R,G,B)測量發光二極體的波長範圍。7. 比較He-Ne 雷射與雷射光筆放光的波長範圍，發現市售雷射光筆所放之光並非單頻。
吃得多,較會生?不同食物量飼養對蓋斑鬥魚生殖行為之影響
自2004年4月29日至2004年8月30日止，研究不同食物量對於蓋斑鬥魚生殖表現之影響。自臺北縣水產種苗繁殖場取得40尾（北縣種苗場字第0930000192號），分成低、中、次高、與最高四個飼養食物量組（3, 6, 9 ,12 顆飼料/每隻魚），每一種食物量組進行四次重複實驗，每一個實驗箱飼養雌、雄魚一對，控制相同的光週期、溫度、密度等變因。結果顯示食物量為中食量組（6粒/隻）泡巢維持時間最長，與其他三組統計上有顯著差異，而其他生殖表現如雄魚的吐泡巢次數、泡巢間隔時間，以及雌魚產卵次數、產卵間隔時間，和魚卵孵化時間等四組之間皆無明顯差異。因此推測不同飼養食物量的處理對於蓋斑鬥魚生殖行為之影響不顯著。From April 29, 2004 to August 30, 2004, we studied the effects on breeding behavior of Macropodus opercularis in different quantities of food. We got forty fish from the nursery in Taipei County. We breed one male and one female in the tank, and the quantities food was set to low, middle, high, and highest groups (3, 6, 9, 12 granule forage per one fish). Every experiment group repeated three times. We also controlled the same light cycle, temperature, and density. We found that the longest maintenance time per one foam nest was breeding in middle group, and there is a statistically significant difference. But the other results had no statistically significant differences between different groups. Therefore, we inferred that the different allowance food feeding control had no significant effect to breeding behaviors of Macropodus opercularis.
