BiFeO3多鐵薄膜成長在FTO基板上不同溫度變化

[[abstract]]本研究以溶膠凝膠法製備BiFeO3多鐵性薄膜，透過旋轉塗佈法將薄膜沉積在FTO基板上，並利用快速熱退火(Rapid Thermal Annealing，RTA)在大氣氛圍下作熱處理。本實驗為純相BFO薄膜沉積在FTO基板上，經不同退火溫度熱處理後的特性比較，探討BiFeO3(BFO)的特性。 本薄膜經不同退火溫度分別為 400℃ 、450℃ 、500℃ 、550℃ 。由實驗結果得知純相BFO薄膜分別沉積在FTO基板上，退火溫度為450 oC時有最佳的晶相，無二次相的產生，並且有最佳的鐵電性

利用3D列印製作植物牆模型探討

[[abstract]]本實驗為有效利用3D列印之功能，做出理想的盆栽，並使用自製有機液肥讓植物能夠長的更好，以達到種植蔬菜不必被環境所限制。 　　液肥發酵的過程中糖度與含氧量愈高會使木黴菌的活性愈好，且發酵過程中會產生酸，也會使糖度降低(以A組為例，糖度在第25日的14.0降低成第30日的8.0) pH值降低(從第一日的4.98驟降到第30日的3.58)電導度值升高(由第8日的15.59驟升到第30日的18.42)，由電導度的變化也可以得知發酵完成的程度。 　　在蔬菜種植的部分，依照實驗構想，有加液肥的種植結果應該要比無加液肥的好，但在田間種植的結果中，無添加液肥之蔬菜最後在總重上比有添加液肥之蔬菜多了0.85倍，至於其他的莖長、葉片大小等，則需要視當下的種植環境及種植期間的天候狀況影響而定。而盆栽種植可能因影響因素較少，在葉片大小與葉寬均有受到液肥的影響。 　　3D列印機需手動校正，3D列印機雖然有自動校正功能，但仍然存在些許誤差，導致列印時噴頭沒有將底面緊密的印在載物平台上，底面才會在冷縮時產生翹曲變形。所以要手動校正，才能確保3D列印機的精準度。在參數設定時，應注意要將填充率設定為90%，以避免孔隙的產生，我們剛開始列印時，參數設定中的體填充率預設為30%，結果成品要從載物平台上拔下時，就因為強度不足，斷裂開了，多次試驗後得知: 填充率愈高成品的結構強度愈佳。90%方為最佳填充率。另外盆栽的結構也極為重要，若掛鉤孔位置太靠近邊緣會導致載重力下降，當掛鉤孔無法承受盆栽的重量時，會導致盆栽掉落或破裂，造成危險。所以我們在設計時有將掛鉤孔的位置往下移動，讓掛鉤孔的邊緣有足夠的厚度，承受盆栽吊掛時的重量，以避免意外的發生。除了這些訣竅之外，要做出完美的盆栽，很重要的一點在於製作3D模型的過程中，要避免不必要的物件綁定，因為重複綁定物件會造成轉檔破圖，因此在3D模型繪製完成後，直接匯出，在列印時才能印出沒有技術破損的成品

The study of current trend on drug abuse behaviour in Hong Kong

This research aims to address three notable aspects of the current trend of Drug abuse behaviour in Hong Kong. Glancing at the latest figures from the Central Registry for Drug Abuse(CRDA)released on March 27, 2014, our group noticed the following: First, there was a decreasing trend on the reported drug abuse population, meaning that less people were taking drugs. Second, the median time for abusers to be discovered by the CRDA reporting agencies has been increasing, meaning that it is taking longer for law enforcement agencies to detect the drug abuser. Regarding the pattern of use, the figures revealed that the majority of drug abusers took drugs at home or at a friend’s home, makingit more difficult to be detected. Last but not least, in view of the increasingly hidden nature of drug abuse, the CRDA has proposed the introduction of the RESCUE Drug Testing(RDT)Scheme. Its purpose is not for prosecution, but to identify drug abusers as early as possible and refer them to counseling and treatment in a timely manner. In view of such, our group target pursued answers to the following research questions: 1. What factors caused drug abusers to quit their drug habit? 2. What factors caused the increased median time for drug abusers to be discovered? 3. Does the introduction of the RESCUE Drug Testing (RDT) Scheme result in a change in the hidden nature of drug use in Hong Kong? This research highlights the reasons that drug abusers quit. It could be useful to circulate these successful cases to other persons who are still thinking about quitting. In addition, the research findings on the causes of the hidden nature of the problem and the former drug abusers’ views on the RDT Scheme could be helpful for other relevant organizations in formulating new policies.published_or_final_versionCriminologyMasterMaster of Social Science
