能源之獲得為當今半導體科技要突破所必須克服的課題，尤其須顧及到環保之要求。所以太陽能之研究及使用已經越趨重要之地位。本實驗用天然的染色子（葉綠素 A 及亞甲藍）當作觸媒劑加在自行研製的太陽電池薄膜： Cul /光敏物質/TiO? P-N型結構。光敏物質／ CuI/ Cu plate P-型結構。 光敏物質TiO?/ SnO?/glaaa N-型結構。不同層次薄膜分別是以溶膠凝膠法及化學沉積法將 TIO?及CuI長在玻璃甚板、鋼基板及 TIO?薄膜上。本實驗的太陽電池薄膜生長速率極其穩定 ( Cul : 0 . 25um/hr , TIO? :2um/hr) ，薄膜照光電壓 0 .01~0 .1V ，照光電流 0 . 030~0 . 050 mA/cm2。

本研究探討運用磁場來達到非接觸煞車的功能，本實驗採用兩種方式來探討磁煞車力，分別為馬達有外加電流及沒有外加電流的情況。首先本實驗提供一穩定的電源使鋁盤轉動，觀察加上磁場及把電源切掉後鋁盤轉速的變化。實驗發現，當馬達沒有外加電流時，磁煞車力與轉速及磁場平方皆成正比；馬達有外加電流時，電流差會與轉速平方差成正比。探討磁煞車力與厚度及介質的關係，實驗結果發現，渦電流常數與厚度成正相關，且當兩片鋁片中夾有介質時，渦電流常數較小。 This experiment is based on the magnetic brake’s practical uses and braking forces. We want to calculate the braking force, and also examine the factors that cause the braking force to differ.We attached a metal disk to a motor to make the disk rotate, then we control the distance between the magnet and the metal disk, therefore measuring the relativity of the distance and the rotational speed. We discovered that when the metal disk received a large quantity of the magnetic field (close distance), the breaking force and the rotational speed increased. On the other hand, when the metal disk received a small amount of the magnetic field (far distance), the breaking force and the rotational speed decreased. The magnetic braking force will convert into kinetic energy, thus, by using this connection and also by increasing the electric current to measure the resistance, we calculated the magnitude of the magnetic braking force. Hence we perceived an inverse ratio between distance and the braking force, that is to say, the closer the distance, the stronger the magnetic braking force; the further the distance, the weaker the magnetic braking force.

聚丙烯酸(PAA)是尿布中吸水成份，我們發現其結構上的羧基能螯合Ag＋，並成功利用甲醛將Ag＋還原成奈米銀。但我們意外發現螯合Ag＋的PAA白色粉末在沒有其他還原劑存在下也會漸漸變成黃色，與「利用甲醛還原製得的奈米銀」顏色十分相似。本實驗即揭開此粉末變色真相，希望能在不使用額外還原劑下，直接以PAA將螯合的Ag＋製成奈米銀，不僅具環保與實用價值，更能使奈米銀製程朝向綠色化學。我們透過水溶性聚丙烯酸鈉(SPA)在均相中進行變色機制探討及影響變因的研究，找出有利的反應條件，再應用於PAA。研究證實PAA能將螯合的Ag＋同步還原成奈米銀，反應機制與檸檬酸鈉作用模式相似，而提升濃度、溫度或照光有利於反應，酸性條件則不利，照各種色光也有所差異。

流量計在實驗室與工業領域裡是重要的儀器，如今已經有數十種依不同物理原理而發展出來的型式，可以配合多變的環境需求與測量條件而使用。然而，各種流量計所適用的範圍備受侷限。本研究主要目的在發展一種熱線式的渦流流量計，供給氣體之流量量測之用。透過自行製作儀器與設備：熱線測速儀(包括探針、探棒及電子處理器)和渦旋產生器(管道中含一三角形截面之鈍體，當流體通過時，在後方尾流產生週期性渦旋逸放)。由於熱線測速儀擁有偵測流體運動時高頻動態變化的能力(約為20000 Hz 以內)，因此結合熱線測速儀與渦旋產生器，經適當的設計與調校，可以測得在不同流體流速時渦旋產生器的三角截面鈍體後方渦旋逸放的頻率。由於渦旋產生器的截面面積為固定值，因此可以從而計算出流量與渦旋逸放頻率的關係。經由嚴格的校準與驗證步驟，本研究的結果顯示自製的熱線測速儀擁有極佳的渦旋頻率偵測能力，所量測到的校準曲線顯示渦旋產生器的三角形截面柱所產生的渦旋逸放頻率與流量成線性關係。為了降低誤差，建議在0 ~ 40 CMM 之量測範圍內分成三條方程式來代表不同範圍內的校準曲線，最大誤差僅在5%以下。若需使用在不同的流量範圍時，僅需改變渦流產生器和幾何尺寸，以使渦旋逸放頻率適合於熱線測速儀的動態響應範圍即可。倘若商品化之後，可以實際應用於風扇流量量測、引擎進氣埠流量的測量等等應用。熱線測速儀本身也可作為風速計，適用於各種場合之風速量測。Flow meter is a instrument that is vital to the laboratory as well as the industrial related field. Based on different physical principles, tens of models that work in harmony with the diverse environmental demands and measurement conditions are developed to date. However, the application of varied flow meters is still under severe restriction. The purpose of this study is to develop a hot-wire type of vortex shedding flow meter for the use of flow rate measurement. Through the home-made apparatus and device, the hot-wire anemometer (includes probe, stem and electronic processor) and the vortex generator. (duct that contains triangle’s section of the bluff body. When fluid passes through, the wake behind produces periodical vortex shedding.) The ability of hot-wire anemometer when it detects the fluid moving changes of high-frequent movement is within 2000Hz, after appropriate design and adjustment, the combination of hot-wire anemometer and vortex generator may investigate the frequency of different flow rate that generated from the vortex shedding behind the bluff body of triangle section. The section area of vortex generator is constant value, thus it can calculate the relationship of flow rate and the frequency of vortex shedding. By means of strict calibration and test procedure, the results reveal that home-made hot-wire anemometer has excellent ability to detect the frequency of vortex shedding. The calibration curve indicates a linear relationship between the frequency of vortex shedding and flow rate. In order to reduce inaccuracy, it is suggested to classify three formulas to represent the flow rate that ranges from 0 ~ 40 CMM. The greatest inaccuracy is under 5%. When applied to different flow rate range, it only has to change the size of vortex generator only if the response frequency of hot-wire anemometer suit for the range of frequency of vortex generator. After commercialization, it can be applied to measure the flow rate of fans, flow rate of intake valve of engine, etc. Hot-wire anemometer also served as anemometer, which can be applied to wind velocity measurement in any situation.

每天，我都要使用到螢光筆。有一天：我粗心地將螢光筆塗到了手指，媽媽看見了我的手指，心疼地說：「媽媽吃東西前，都要先將唇上的口紅擦掉，以免食用化學品中毒，你使用螢光筆也要小心才是呀！」我聽了驚覺：是呀：螢光筆塗起來顏色鮮艷，聞起來有收化學味，對人體或其他生物是否會有不良影響呢？於是，我動手做了對螢光筆的探討。

(一)雪豆的睡眠運動乃因葉枕上下細胞膨壓之改變所致，而 k＋之進出於細胞內外，引起細胞膨壓產生變化。(二)根據食療法知：雪豆可治療神經衰弱，又可作為緩瀉劑。(三)動物神經突觸間產生乙醯胆胺，傳導神經衝動，而衝動的傳導乃k ＋由神經細胞中轉移到細胞外；乙醯胆胺又可促進消化道的蠕動。(四)雪豆能日出而醒日落而睡，光照與黑暗似可控制其睡眠運動。

實驗室或化學工業製程所產生的廢水中常含有有毒物質，若未經處理直接排放而使河川的自淨能力無法負荷時，將對環境產生嚴重的危害。這些有毒物質包括強酸、強鹼、酚、氰化物及各種重金屬，依其污染物性質的不同，需利用各種不同的去除方法來達到預期的處理效果。近年來高分子合成技術的創新，使具有選擇性吸附的高分子型吸附劑，在去除水中有機物和重金屬上，已有突破性的發展。但此種吸附劑的價格過高，不符合經濟效益。因此，如何選擇一個適合的吸附劑，是一個值得深入研究的課題。常用的吸附劑有活性碳、粘土、矽石、兩性澱粉等。對於去除低濃度有機物或重金屬離子時，用一般處理方法較不經濟，且不易達到理想的去除效率，此時可利用吸附劑如界面活性劑或雜環族有機物等，以達到較高的去除效果。而吸附劑的選擇不但需考量吸附效果的優劣，吸附劑的來源是否容易取得，吸附反應時間的長短、飽和吸附量及吸附後廢棄物的後續處理問題等，都是必須考慮的因素。本研究利用豆渣作為吸附水溶液中重金屬的吸附劑，來探討豆渣在不同時間、不同粒徑下對水中重金屬鎘的吸附能力和去除效果。實驗結果發現：豆渣吸附時間在短時間即可達到吸附平衡，去除率在 60﹪至 75﹪左右；豆渣粒徑的大小會影響吸附能力，以 D4（0.250mm~0.061mm）效果最好，當粒徑較小時，其表面積較大所以吸附效果較好。另外，藉由 Langmuir 等溫吸附曲線可決定豆渣對鎘的最大吸附量。實驗中所使用之吸附劑（豆渣）與吸附質（重金屬－鎘）之吸附行為符合 Langmuir sorption isotherm equation，可得到一最大吸附量。

The special life cycle of the Nymphoides indica: The veins and petioles of the pleustonic leaves can asexually reproduce adventitious buds. Pleustonic adventitious buds will change the density of the plants and sink into water. When the root of submersible plants attaches to the bottom of the pool, they will extend stems to the water surface and resume the life cycle. Reticulate sigmons and astral sclerenchyma appears in the process of transformation. Astral sclerenchyma merely appear in the species of which its leaves float above the water surface, and Nymphoides sp. are the most obvious. The cell wall thickness of astral sclerenchyma is even. The cells are hollow and full of water, and they will utilize water to change turgor between axes and spines. This is also proved in imitating experiments. The reticulate sigmons are frequently seen among aguatic plants, and the horizontal structures prevent air space from collapsing. These two structures make the thin stems of Nymphoides indica sustain the leaves instead of being crushed by the floating water. 印度莕菜 ( Nymphoides indica )獨特的生長週期：浮水型葉的葉脈和葉柄可以無性繁殖不定芽，浮水型的不定芽會改變植株的密度而沉入水中，當沉水型植株的根系在池底固著後，便會以莖延伸出水面，再次展開浮水型葉的成長週期。轉變過程中會出現網狀的橫膈和星狀厚壁細胞。星狀厚壁細胞僅出現於葉片需由水中浮出水面生長的植物種類，而莕菜屬植物更明顯。星狀厚壁細胞其細胞壁厚度均勻，細胞中空且充滿水分，會利用水分在中軸與突起的棘間移動來改變膨壓變化，在模擬的實驗中也得到證實。網狀的橫膈在水生植物中是較常見到的構造，水平方向的支撐可以讓氣室不會塌陷，兩種構造的作用下使得印度莕菜細長的莖能夠支撐葉片，不會被流水沖斷。

利用川燙地瓜葉可以誘捕螺類，這種自然捉螺方法讓我們感到新奇，於是進行這一次科學研究。首先，透過實際觀察、閱讀資料和請教專家，才確認我們所研究的螺類是「紅扁蜷」。然後，從飼養觀察過程不斷發現問題，並進行實驗來印證我們的猜測。經過研究後，我們更加了解紅扁蜷的生活習性：紅扁蜷屬於腹足綱－有肺亞綱－基眼目，避光性喜歡在陰暗處活動、覓食；紅扁蜷在15℃以下的水溫活動力不佳，在20℃到30℃的水溫中活動力明顯較好；加入珊瑚礁石可以幫助紅扁蜷生長，但珊瑚礁石與紅扁蜷的聚集現象無關；紅扁蜷是腐食性動物，經川燙過的菜葉或切片在水中會加速腐爛，因此可以有效誘捕紅扁蜷。比較不同菜葉的誘捕效果，其中以油菜葉的效果最好。

我們用環保的「紙」來製作環保紙吸管，使用洋菜液體浸泡後冷凍與冷藏，讓紙吸管具備防水功能，也增強耐用性。我們用道林紙和粉彩紙製做紙吸管的主體，和市面上的塑膠吸管比較，在掩埋實驗中，自製的洋菜紙吸管明顯在土壤中分解；而塑膠吸管完全沒有分解；耐折實驗中，洋菜紙吸管每個都超過140個華司，塑膠吸管平均只能耐97個；在垂直耐壓實驗中，洋菜紙吸管每個都能承受15kg以上的重量，而塑膠吸管只承受不到10 kg重量；在燃燒實驗中，塑膠吸管在燃燒時，會發出難聞的惡臭，但洋菜紙吸管不會；戳洞實驗裡，道林紙有洋菜冷凍的，刺破飲料杯保護膜的效果最好，其他，用來吸取珍珠、吸水和耐輾壓等實驗中，自製的洋菜防水吸管都不輸市售的塑膠吸管。

Objective To design build and run 5 Mouse mobiles – vehicles which use mousetraps as their only source of energy. Targets- • Go up a ramp • Raise a flag • Hit something and set it free • Deliver something • Catapult Details These mouse mobiles are original creations which include some commercially produced parts. They are powered by single spring driven standard wooden mousetraps. They are 5 in number each being used for the respective tasks. Basic structure Each mousetrap consists of a 2 parallel wooden planks which has 2 holes drilled on either sides for the rear and front axles. A rod is used as the axle and CD disks are used as wheels. The mousetrap is attached to the planks. Movement and Locomotion To move the mouse mobile a string is connected to the rear axle. The string runs through 2 pulleys which change the direction of the applied force and are attached to the hammer of the spring. When the vehicle is pulled backwards on the floor tension is created in the string (as the hammer is stretched) which gets stored in the form of spring energy. When the wheels are released on the floor the rear axle starts rotating hence propelling the mouse mobile forward. Completion of objectives 1) To go up a ramp For the required task a high amount of torque would be needed .That will be sufficiently provided by the spring energy. 2) Raise a flag For the required task a rod is placed on the wooden platform. The flag is placed at the bottom of the rod; it is connected to the hammer of the mousetrap using a string. The spring and the rod are placed in the opposite directions. When the hammer is released after being stretched it pulls the string and raises the flag. 3) Deliver something For the required task 2 mouse mobiles are used. A platform of any hard and light material is attached to the rear of a mouse mobile. After reaching the desired location, when the hammer of the primary spring is fully relaxed it hits the catch of another stationary mouse mobile. The hammer of the respective catch is connected to the platform using a string. Upon activation the hammer is released, the platform is pulled with extremely high speed and the materials on the platform, due to their moment of inertia fall down. 4) Hit something and set it free. For the required task 2 mouse mobiles are used. A small mousetrap is attached to the front of the mouse mobile which is in contact to the required object. The other mouse mobile on reaching the above vehicle hits its catch using its hammer. The hammer of the stationary mouse mobile is released and the object is hit and set free. 5) Catapult For the required task 2 mouse mobiles are used. A mousetrap is attached to the front of stationary mouse mobile which is attached to a strainer and the object to be catapulted is placed inside it .Another mouse mobile approaches is and hits the catch hence activating the hammer and the object is catapulted.

自從保麗龍問世以來，最先大家都用在包裝業上，做保護物品之用，接著從包裝業發展到廣告業，如今連裝飾上也採用到它。由於裝飾及廣告業都是些圖形字體，故需要鋸切，鋸切工具除了以鋼鋸條製成的鋸切刀外，亦用電熱絲來鋸切。
