海水倒灌一直是台灣西南沿海地區居民揮之不去的夢靨，所以本研究的目的即根據資料了解西南沿海地區的地質、地勢、現況以及參考專家分析造成海水倒灌的可能因素後，因此設計了【模擬沿海地區海水倒灌的模型箱】，再進行【超抽地下水會導致地層下陷及海水入侵的實驗】、【了解地下水鹽化灌溉農作物的生長情形】，最後企圖找出農作物鹽化的即時處理及土壤鹽化恢復的方法，還有利用太陽能以低壓簡易蒸餾的方式模擬海水淡化的可行性，希望能解決海水倒灌的後遺症問題。Inwelling is a problem which has affected the inhabitants of the coastal regions of Southwest Taiwan for many years. This study examines the geological and topographical structure of the coastal regions of Southwest Taiwan, and considers experts’ views on the possible causes of inwelling. This information is used as the basis for designing a box for modeling inwelling in the coastal regions, experimentation to study land subsidence and inwelling caused by excessive extraction of groundwater, and examination of the impact on crop growth of irrigation using groundwater which has been affected by salinification. Finally, the study seeks to find methods for dealing promptly with the salinification of agricultural crops and for the remediation of salinified soil. In addition, solar energy is used (with a simple, low-pressure distillation method) to model the feasibility of desalinifying seawater in the region in question, in the hope that this will help to remedy some of the aftereffects of inwelling.

生物系統的力學表徵會因為其系統內部物理結構和化學組成的改變而變化。本研究希望能找出斑馬魚魚卵的彈性力學特性與其成長發育的關聯。本實驗利用自行設計製作的電磁力振盪儀器分析斑馬魚魚卵的彈性力學特性。實驗上使用自製電磁線圈對槓桿端所繫磁鐵作用，使桿間連棒對魚卵施加作用力。由於斑馬魚魚卵形變量很小，本實驗加入光槓桿的設計來放大微小的形變。實驗時以錄影記錄施力對魚卵產生周期振盪彈性形變關係。\r 本研究實驗得到，魚卵的彈性力學特性是隨發育時期改變而不同，但不是隨時間而單純線性演化改變。本研究關注於魚卵囊胚期彈性力學特性。發現囊胚期不同發育階段，魚卵的彈性振盪特性會有所不同。本實驗進一步以阻尼振盪模式分析振盪振幅的改變，可以得到魚卵生物阻尼係數。發現阻尼係數在囊胚期最初的前一個半小時的改變最為顯著，也就是會與該期細胞移動有關。本研究可以作為判定魚卵在不同發育時間的生化微觀機制，也可進一步作為分析環境變遷對生物族群影響的探討參考。

水生食蟲植物絲葉狸藻 (Utricularia gibba) 是非常獨特的，它不但跟其他植物一樣能行光合作用，且具備捕蟲囊捕捉水中小生物，補充生長所必需的營養元素。捕蟲囊的構造精密卻不複雜，消化吸收主要靠囊內壁上的四爪腺毛，目前尚未有文獻實際以追蹤物質描述出整個共質體輸送路徑。我們是最先以螢光染劑 (carboxyfluorescein) 及共軛焦雷射掃描顯微鏡(confocal laser scanning microscope) 成功地描繪出捕蟲囊共質體運輸路徑。同時我們也以對細胞無害的食用色素，進行相同的實驗觀察。發現食用色素不但成本低，且較螢光染劑有更多的優點，如觀察時間較不受限制等，非常適合用來研究捕蟲囊吸收物質的路徑，因此，本實驗的模式可以應用在其他水生植物運輸路徑的研究。;The aquatic carnivorous plant Utricularia gibba is very unique. It has not only the ability to undertake photosynthesis just like other plants, but also can trap and obtain the nutrients from the freshwater zooplankton. Its trapping organ is very sophisticate but not complicate. The digestion and absorption process inside the trap are mainly accomplished by the quadrifids structure. According to our knowledge, we are the first to introduce the phloem-mobile, fluorescent probe carboxyfluorescein (CF) and confocal laser scanning microscope (CLSM) to the study of the symplastic transport in the Utricularia trap. In addition, we use edible food colorings as tracers for this transport study. Both approaches turn out to be very successful in delineating the symplastic transport of the trap. But CF quenches rapidly so the observation time is restricted. On the contrary, food colorings don’t have these disadvantages; it is inexpensive, easy to perform, and the transport process is not fast. As a result, the study is easily to be completed. These methods will be very helpful in the studies of symplastic transport in other plants.

視覺經驗訊息的top-down process能增強動物對影像的辨識能力，這種透過先前學習過的經驗而增進視覺辨識的能力，與一般熟知視覺是由眼睛將影像訊號傳至大腦進行辨識的過程恰好相反，因此被稱為top-down process。本研究以Y型迷宮進行訓練蜜蜂的行為實驗，首先提供無法直接辨識的複雜影像，再經過提出的簡單影像特徵進行訓練後，再以原先無法直接辨識的影像予以測試，證實蜜蜂也具備這樣top-down process訊息的能力。此外，藉由改變各種視覺影像特徵，進一步探討這樣的視覺訊息可能傳遞路徑。藉由擷取、篩選後的重要影像訊息復甦相關視覺經驗以增強辨識能力，有助於蜜蜂以更有效率的方式訪花。蜜蜂大腦體積不到1 mm3，卻有處理如此複雜視覺訊息的能力，其行為與神經機制實值得深入探討。

當我們在開車享受冷氣同時，此時冷氣水正一滴一滴的滴水，造成水資源的浪費，在環保意識抬頭的今天，我們即針對此一問題進行研究，主要將冷氣水回收起來，並運用在補充雨刷水箱或者提供引擎水箱或冷凝器降溫作用，是否達到提高引擎工作性能及降低冷氣冷房效果，進而達到「資源回收」的。實驗結果證明在補充雨刷水系統最符合環保概念；另在引擎水箱噴水作用時，可縮短風扇運時間並增加停止運轉時間，可增長風扇使用壽命，對下水管溫度亦可降低，可防引擎過熱；在冷凝器噴水作用中亦能明顯提升汽車冷房效果。When we enjoyed driving with cool air from air-conditioning, the condensed water from air-conditioning system is dripping from the system drop by drop. It caused the issues of the waste of water resource. Facing the greater public awareness of environmental protection issues in Taiwan, we are focusing on this issue to have further research. The idea is to re-cycle the air-conditioning condensed water and re-fill it in the water tank of wipers, the water cooling tank of engine or the cooling system of condenser. The purpose is to improve the performance of engine and enhance the cooling efficiency of air-conditioning system. It is helpful to meet the objective of water resource recycling. The result of experiment has shown that re-filling water in the water tank of wipers meet the goal of environmental protection well. Also, the water injection in the water cooling tank of engine could reduce each operation time of cooling fan and increase the idle time of cooling fan as well. It prolong the equipment life of cooling fan and lower the operation temperature of Low water pipe which prevent the engine overheating. Meanwhile, It is proved that the water injection in the cooling system of condenser can enhance the cooling efficiency of air-conditioning system.

大氣圈、水圈與土壤圈是構成自然環境的三大領域，三者之間相互的影響，原本這些空間都具有極大的包容力，亦所謂「自淨能力」，許多的物質進入其中皆會被氧化分解或稀釋而消失於無形。近年來由於工業發展、人口增加，產生大量的廢棄物，長期、密集且迅速的堆積於環境中，使得天然的自淨能力無法應付而失去功能，造成嚴重的後果。就土壤而言，雖有較佳的自淨能力，但是一受污染，除了嚴重破壞土壤品質之外，同時也會直接或間接污染水源 (如:地下水)及空氣，對動植物造成危害，並且難以回復，實不容忽視。本實驗探討:一、土壤淨化能力是否受到不同地區、不同土壤性質的影響。二、同樣的土壤，對不同的污染物(色素、肥料、重金屬)淨化能力強弱的影響。實驗結果顯示大肚山土壤過濾溶液中的色素、磷、及重金屬中的鉻、鎳、銅的能力較中寮及大甲土壤強，只有氮與鉀的過濾能力較大甲土壤差，所以這次實驗中大肚山土壤有最好的污染淨化能力。實驗結果將來也許可以應用於土壤處理場址之適宜性評估。The air, water and soil are three parts of the nature. They affect each other. In fact, they have the "self-purity ability" - they can disassemble many polluted thing by this kind of self-purity ability. These years, because the industry development and the population explosion make lots of waste, the self-purity ability cannot do its best. The soil has better self-purity ability, but if it is polluted, it will not only pollute the water (ex: underground water) and the air, but also damage the animals and plants. We cannot ignore the serious result. This experiment will discuss:1. If the soil self-purity ability is affected by different area and different soil specificity? 2. The different purified results according to the different pollutant (ex: color, fertilizer and heavy metal) in the same soil. Results showed that Da-Du-San soil had strong ability then Chung-Liao and Da-Cha soil in filtrated color, phosphor, chromium, nickel and copper in the solution, but had weak ability then Da-Cha soil in filtrated nitrogen and potassium. Therefore, Da-Du-San soil had the beast pollution-purity ability in this experiment. In the future, results may be applied to the suitability evoluation of the soil treatment place.

“熱巧克力效應”是當你將巧克力粉加入裝有熱水之馬克杯後用湯匙輕敲杯壁，可以聽出攪拌前後敲擊所得聲音頻率明顯不同，攪拌後巧克力粉溶解頻率會較高。一般論文的解答是「當粉末溶解的時候，藏在粉末裡的空氣就會跑出來，在空氣與水混合的環境裡，音速比在水裡低。當水裡不斷有空氣與水混進去時，這個容器的共振頻率和它裡面的音速有關，所以也會降低。因此你會聽到較低之音調，直到空氣全跑光。」但根據我的實驗我覺得這樣的解釋並不對。我們提出新的模型來解釋“熱巧克力效應”。When we put an ounce of dry chocolate powder into a mug filled with hot water, then tapping the side with your spoon will generate a sound. The pitch of this sound will rise after stirring. This is called “the hot chocolate effect”. According to a published paper, the explanation is “The air trapped in the powder is released as the powder dissolves. Since the speed of sound is lower in air than that in water, the speed of sound in the air-water mixture is lower than that in pure water. During that period while the air escapes the container, the resonant frequencies of the water, which depend directly on the speed of sound, will also be lower. Hence, you hear a lower tone until the air escapes”. However, our experiments clearly demonstrated that the explanation is plainly wrong. A new theoretical model is also proposed for the observed phenomenon.

本研究在探討薑黃、南薑、野薑及一般薑等所含薑黃素的抑菌與抗氧化作用特性，及其在生活及教學上之應用。研究發現：（1）抑菌能力排序：以薑黃最強；一般薑次之；南薑、野薑微弱。（2）抗氧化作用仍以薑黃最為明顯，其餘不顯著。（3）在生活上之應用方面，薑黃素用於檢測水質及食品中是否含硼砂，可明確檢出含硼量；薑黃素所含的天然色素，可用於布料之染色及食品用色素添加劑，亦可用於製造薑黃手工皂，對人體皮膚有益處。（4）在化學實驗上，薑黃素製成薑黃試劑，可做為酸鹼指示劑，另可檢驗一般居家物質之酸鹼性。由以上實驗結果可知薑黃素應用甚為廣泛且深具利用價值。

因國際原油價格上漲，因此對研究及發展具潛力的生質柴油引起高度興趣。傳統以加熱方式在適當觸媒下將低碳數醇類與油脂轉酯化生成生質柴油。但以強鹼為觸媒使用過量會讓部分反應轉為皂化。而利用微波，使微波腔在極短的時間內產生電場，使具有電偶極的分子朝向電場方向迅速排列而產生轉動，快速地增加分子間的碰撞頻率而加速反應，但不破壞分子結構。也嘗試利用超音波來生產生質柴油。試驗方法為利用SD-22 柴油引擎測試所生產的生質柴油，並收集廢氣檢驗，評估其污染性。實驗後發現，微波能將一般加熱所需的60 分鐘大幅縮短至4 分鐘，甲醇溶液能生產較多的生質柴油。其中1.40%氫氧化鉀甲醇溶液且油與醇莫耳比1：9 效果較佳。氫氧化鉀甲醇溶液0.80%且油與醇莫耳比1：5 效果亦佳。製成的生質柴油能讓引擎發動，廢氣處理後經分光光度計檢驗氮氧化物，生質柴油確實能有效減少氮氧化物污染。 Due to the fact that the price of international crude oil raises , people look for alternative energy resources actively. Therefore, I have great interests in doing researching and developing the biodiesel through many ways. The traditional way is to transesterify the low carbon alcohols and fats with the suitable catalysts by means of generally heating. However, the overuse of strong bases as catalysts may turn the experiment result into saponification reaction. This study made good use of the microwave to generate electric fields in the microwave cavity in an extremely short time. Owing to the effect electric fields exerted, the molecules with electric dipole momentum rearranged to rotate rapidly .Consequently, the frequency of collision among the molecules increased without destroying the molecule structures. Also, I applied SD-22 diesel engine to test the produced biodiesel and examined the collected exhaust to evaluate its pollutant. According to the results of these experiments, the conclusion was as following: the microwave could shorten the Transesterification reaction time from 60 minutes to 4 minutes. The methanol solution could produce more biodiesel than the ethanol solution. Besides, the 1.40 wt ％ Potassium hydroxide solution with the molar ratio of oil and methanol 1:9 had the best efficiency in producing biodiesel. On the other hand , the 0.80 wt ％ Sodium hydroxide solution with the molar ratio of oil and methanol 1:5 also had the great efficiency. All the biodiesel we produced enabled the diesel engine to run smoothly. The exhaust inspected from the examination of Spectrophotometer resulted that the biodiesel did less NOx pollution to the environment indeed.
