[[alternative]]The Relationship of Settlement Development of Taoyuan District and Feng-Shui

[[abstract]]　　桃園區所轄地區在清領之前係屬平埔族原住民之居住地，並無任何文字紀錄，康熙年間將臺灣納入版圖後，漢民族大量移入墾拓，聚落因而快速形成，始有文字的開發紀錄。　　清初對北臺灣行政管理作為並不積極，但隨著民間力量的開墾，官方力量也緊接著進入該地區。直至嘉慶年間，桃園地區才進入設官管治的階段，且桃園自設縣起迄升格為直轄市，桃園區均為縣治所在，歷經日治、光復後等時期行政區之變革與發展成為現今桃園市政治、經濟、文教及交通中心。　　本研究基於「地方公廟之風水吉凶可以影響當地的財丁貴秀」之假設議題，以大正14年至民國104年間的桃園區及其傳統聚落發展之公共層面為時空範圍，以景福宮為立極點，運用大數據概念，從內容具權威性之政府出版品，客觀取得的數據資料，說明風水的實證性，試圖超越過去長期以來風水堪輿強調個人家宅及命運解讀的限制，經研究結果後發現，與三元理氣的風水法則具有相對可信度。[[abstract]]　　Before being annexed and ruled by the Qing dynasty, the territory now administered by Taoyuan county was the inhabited area of Taiwanese plains aborigines, collectively termed Pingpu Tribe, where no record of writing system has ever been found to date. The declaration of the Qing dynasty to annex and incorporate Taiwan into it's empire during the Era of Emperor Kangxi led to an enormous influx of the Han people to settle down, thus rapidly forming settlement clusters and initiating the development and record of writing.　　At the beginning the Qing dynasty was not active in the administration of northern Taiwan, but it's official influence then started to grow, following the civilian settlers'pioneering efforts. The Taoyuan area had not entered the stage of official administration until the Jia Ching administration period. Before being upgraded as one of Taiwan's municipalities, the whole of Taoyuan area was governed as and under a county city but is now Taoyuan municipal city's political, economic, cultural and educational as well as traffic center made possible by the administrative reforms and development evolving through the stages of the sovereignty under the Japanese occupation, the KMT administration in the early years of Taiwan Retrocession as well as the recent development of Taiwan's political systems.　　This study is based on the hypothesis that "the influence of the Feng Shui of local temples on local wealth and outstanding people". The research chooses Jing Fu temple as the field, during the period from the 1925 (Taisho year 14) to the 104th years of the Republic of Taoyuan and its traditional settlement development, based on the concept of big data, from the content of the authoritative government publications, the objective data obtained, indicating the feng shui of the empirical, trying to go beyond the past feng shui geomancy emphasis on individual home and fate interpretation of the restrictions, the study found that the San Yuan Theory has a relative credibility

Morphology Controlled Preparations and Electrochemical Properties of ZnCo2O4 Electrode Materials for Supercapacitors

本文采用水热反应和高温将ZnCo2O4纳米活性材料原位生长在泡沫镍上，并通过控制前驱体溶液中NH4F的添加量，获得了ZnCo2O4四种不同的形貌. 以ZnCo2O4-2/NF为正极，AC/NF为负极，组装得到纽扣式非对称超级电容器ZnCo2O4-2/NF//AC/NF. 通过X射线衍射（XRD）、场发射扫描电镜（FESEM）、透射电镜（TEM）等方法对四种形貌ZnCo2O4的组成和结构进行了分析. 在三电极体系下对不同形貌的ZnCo2O4电极进行循环伏安、恒流充放电以及电化学阻抗测试. 结果表明，当NH4F的添加量为5 mmol时,所获得的薄纳米线团簇具有最高的面积比容量. 在电流密度为5 mA·cm-2下，比容量为2.77 F·cm-2. 基于正负两个电极的总面积，纽扣式非对称超级电容器的最大能量密度达到114.49 μWh·cm-2，相应的功率密度达到4001.59 μW·cm-2. 同时，功率密度达到24000 μW·cm-2时，对应的能量密度为80 μWh·cm-2.In this work, hydrothermal reaction and high temperature were used to grow ZnCo2O4 active materials on Ni foam. The crystal stuctures and surface morphlogies of four samples were investigated by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM). The electrochemical performances were characterized by cyclic voltammetry (CV)、galvanostatic charge/discharge (GCD) testing and electrochemical impedance spectroscopy (EIS) on an electrochemical station. It can be seen that active materials tended to form denser stuctures with an increasing amount of NH4F in the solution system and four different morphologies of ZnCo2O4  were obtained: nanoneedles, thin nanoneedles-clusters, thick nanoneedles-clusters, and lozenge-like bulks.ZnCo2O4 with the thin nanoneedles-clusters morphology held the best electrochemaical performance with the capacitance of 2.77 F·cm-2 at the current density of 5 mA·cm-2. A button asymmetric supercapacitor (ZnCo2O4 -2/NF//AC/NF) assembled with ZnCo2O4 -2/NF and AC/NF exhibited the excellent performance in energy storage. The button asymmetric supercapacitors achieved an energy density of 114.49 μWh·cm-2 at power density of 4001.59 μW·cm-2 and a power density of 24000 μW·cm-2 at energy density of 80 μWh·cm-2.无作者联系地址：1. 江苏科技大学材料科学与工程学院，江苏 镇江 212003；2. 南京大学材料科学和工程系，江苏 南京 210093Author's Address: 1.
