安培植物假說
在「植物的秘密生命」這本書中提到植物在電場或磁場中會生長的更好,我最近正好學到了電磁場如何產生,以及一些產生電磁場的方法,所以想利用螺形管線圈來產生均勻的電磁場並用安培右手定則來控制磁場產生的方向來了解電磁場在高低室溫下對綠豆生長的影響. 在本實驗中我利用鐵碗纏繞線圈的方式並通入不同的電流大小來改變磁場的強度,所進行研究所得到的結果顯示(1)綠豆只有在適當的電流大小下所產生的電磁場才可以幫助加速綠豆的生長(2)栽培綠豆的環境所架設的電磁場越高,越能持續讓綠豆的生長加速(3)綠豆的加速生長並不需要整天都通電(4)綠豆在N極朝上的磁場中生長的速率較S極朝上的磁場中要快(5)在較低的室溫下,電磁場加速綠豆生長的效應較能顯現 It has been mentioned that the plants will grow faster in the electronic or magnetic field in the book of “the secret life of plants”, I learned about the knowledge and methods of how to produce the electromagnetic field just now, I use the screw wire to produce electromagnetic field and control the direction by the Amplifier’s rule to investigate the growing speed of green beans under electromagnetic field in those different temperature. In this experiment, I use the wire to screwed around the ironed bowl, and make different electric current to generate different strength of electromagnetic field, the results indicate that (1) The faster growing speed will only exist in some strength of electromagnetic field (2) The higher ironed bowls that full of screwed wire will result in the faster growing speed (3) It will not need electromagnetic field all days (4) The green beans will grow fast in those north magnetic pole than those in south magnetic pole (5)The effect of electromagnetic field to increase growing speed will be significant in higher room temperature
就是那道光-色素增感型太陽能電池改良之探討
在這能源短缺的時代,開發替代能源已經成為主要課題。利用光觸媒特性所製成的色素增感型太陽能電池,因二氧化鈦光觸媒受到紫外光照射才產生電子躍遷,吸收光的頻率區域狹小,實用性不高。因此研究氧化鋅、二氧化錫與二氧化鈦混合,是否能提升該電池的轉換效率。藉由各種變因的探討,從中選取最有利的方式,使太陽能電池發揮更大的效益。除了以溫度、電解質、混合比例等因素外,增加電極面積以及串聯均可提高電壓與電流,以增加日常生活的實用性。如不斷的改進發展,諸如電解水、使小燈泡發光,甚至各種小家電用品的使用,都可應用於其中。In times of energy shortage, exploring the alternative energy has already become a main issue. The dye solar photocell is using photocatalyst characteristic. Because the electron transition is caused by lighting up the titanium dioxide photocatalyst by the ultraviolet, the frequency of spectrum is narrow and small. It is thus impractical. Therefore, we research whether or not the mixtures of zinc oxidize and tin oxide with titanium dioxide can improve the conversion efficiency of the dye solar photocell. Through discussion on various kinds of factors, we can choose the best way to make the dye solar cell yield more efficiency. In addition to the factors such as temperature, electrolyte, mixed proportion, etc., increasing the area of electrodes and contact can improve the voltage and electric current. That way we can increase the practicability for daily use. With constant improvement, it can be applied to many kinds of things, such as electrolyzing water, small bulb lights, even small household appliances.
由心血管超音波影像之動態分析研究主動脈硬化
我們的研究工作有兩項重要成果:首先,根據物理學的彈性體振動模型發現:主動脈硬化的定量分析訊息可由測量主動脈相對於心臟運動的延遲時間明確得知,而且可用目前臨床使用中的心臟超音波儀器直接進行此一測量。在對23 個樣品、每個樣品分析大約50至100 次心跳的初步研究中發現,此一延遲時間是確實存在的,而且延遲時間超過大約0.17秒時,樣品就可能具有動脈硬化的現象。其次,在比照過10 組樣品的數據後發現,上述之延遲時間確定可由體外的胸前超音波掃描(TTE)準確測得,而不需要採用侵入式的經食道超音波掃描(TEE),以免除受測者的不適,及避免副作用的風險,使得此一新方法更具有方便、普遍的優點。而且此一方法也可能由數據的分佈發覺心血管之其他病徵。未來仍需應用此一方法對較多樣品進行研究以進一步確定此診斷方法之可靠性。 Two important results were achieved in this research. Firstly, according to the physical model of elastic oscillation, we found that the qualitative analysis of aorta stiffness could be obtained by a measurement of the delay time of the aorta motion relative to the cardiac motion. This measurement could be carried out with the conventional echocardiography. A preliminary analysis based on 23 samples, with 50 to 100 heartbeats per sample, confirmed the existence of this delay time. Also, a delay time of greater than 0.17 sec might imply the symptom of aorta stiffness. Secondary, after a comparison of 10 samples, the aforementioned delay time could be measured with TaransThoracic Echo (TTE) instead of TransEsophadeal Echo (TEE), in which the later is invasive while the former is not. Therefore, the discomfort of the patient and the risk of invasive operation can be avoided, making this new method more convenient and more common to accomplish. This method could also clearly discern some abnormal cardiac performance. A large-scale study with this method should be conducted in the future.
