CH_4-CO_2重整制合成气Ni基催化剂的失活研究

ＣＨ４－ＣＯ２重整制合成气反应（ＭＣＲ）中导致Ｎｉ基催化剂失活的主要原因可能有二：一是助剂组份碳酸化生成稳定碳酸盐物种毒化了反应活性位；二是笼状（包括石墨态和无定型态）炭的沉积覆盖了催化剂表面。ＭＣＲ反应中炭的沉积主要有两种形式：一是以须状形式进行堆集，二是以笼状形式覆盖于催化剂表面，前者对于催化剂活性的保持似无明显影响，后者则是导致催化剂失活的主要原因之一

Collecting Related Facebook Pages via Shared Post: Sunflower Movement as an Example

近年來隨著Facebook的盛行，Facebook已成許多人紀錄生活或關注朋友近況不可或缺的管道。除了個人動態之外，公開的Facebook粉絲專頁作為名人或組織與廣大用戶之間的交流管道，彼此透過貼文、按讚、留言與分享等，進行密切的互動與交流。許多學者因此試圖透過Facebook應用程式介面(API)蒐集粉絲頁用戶的活動行為紀錄(如貼文、留言與轉貼等)，進行研究分析，以期更理解人們透過粉絲頁進行的交流與訊息傳播活動。 本研究即以粉絲頁間的貼文分享為出發點，尋找當公共議題事件發生時，粉絲頁間透過分享而產生的互相關聯性。為了驗證此一想法之可行性，我們設計與實作了一套「透過貼文分享以蒐集相關臉書粉絲頁之機制(Collecting Related Facebook Pages via Shared Post) 」系統，讓使用者可以針對其關注之公共議題事件設定原始種子粉絲頁及指定資料蒐集期間及設定相關蒐集參數。系統會透過Facebook 公司提供的應用程式介面，並自動蒐集種子粉絲頁指定期間之貼文、貼文留言、貼文按讚資料。每一次資料蒐集完成後系統會分析是否具有符合使用者指定條件的新粉絲頁，並將之加入新種子粉絲頁的行列，逐次推導出完整的粉絲頁關聯性。 本研究以太陽花運動相關粉絲頁作為實驗對象，透過我們的系統分析種子粉絲頁裡的貼文分享，逐次找出多個性質相近的粉絲頁並建構出關聯性粉絲頁群組，所得結果符合實驗的目的。In recent years, Facebook has become a very popular social media with millions of users. Besides personal walls, many celebrities and organizations leverage the public Facebook pages to engage their fans for developing their brands or promoting their ideas. Due to their public nature, Facebook pages have become good targets of social communication research by scholars. In this thesis, we propose to investigate the relations among Facebook pages built by post sharing activity during public events. Toward this goal, we have designed and implemented a system for analyzing posts sharing among Facebook pages. It allows users to set initial seed pages, related parameters and duration of collection on the public events they concern. Our system will collect specified pages data (posts, comments, likes) of original seed pages through Facebook graph API. After the data collection period, the system will analyze whether the new pages fit the user specified criteria, and adding the new pages into the page pool for next stage of collection. In other words, our system will iteratively collect pages related by post sharing. As an evaluation of our system, we conducted an experiment based on the Sunflower Movement and use Facebook posts of seed pages to find new similar pages to construct groups of similar pages. The experimental results show that our system can collect many related pages and help scholars to group them by sharing in a meaningful way

(51(2):111-124)Effect of Ethylene and Preservatives on the Vase Life of gerbera jamesonii Cut Flower

本試驗以商業栽培品種“Furore”和“Ornella”非洲菊切花為試驗材料，探討外加乙烯、乙烯抑制劑及保鮮液對切花瓶插壽命之影響。非洲菊切花以外加0.1～10 ppm 乙烯處理24小時雖會刺激呼吸率和乙烯釋放量之增加，但對瓶插壽命影響並不顯著。以乙烯抑制劑胺基三唑 (aminotriazole; ATA) (1.2mM)、1-甲基環丙烷 (1-methylcyclopropene; 1-MCP)(1800 ppb)、Retain (100 ppm) 和硫代硫酸銀 (silver thiosulfate; STS) 處理，亦無法延長其瓶插壽命，顯示非洲菊為對乙烯不敏感之切花，且乙烯並不是影響非洲菊切花老化之主要因素。以1,3-二氯- 5,5-二甲基乙內醯脲 (1,3-dichloro-5, 5-dimethylhydantoin; DDMH)、NiCl2配合蔗糖之保鮮液預措2小時，能有效的延長非洲菊切花瓶插壽命，其中“Furore”非洲菊以1.25 ppm DDMH + 250 ppm NiCl2 + 0.25% 蔗糖之效果最佳，“Ornella”非洲菊以25 ppm DDMH + 500 ppm NiCl2 + 0.5% 蔗糖最佳，皆可增加約4天之瓶插壽命。此外，亦探討保鮮液預措後對切花之吸水性、鮮重變化、呼吸率和乙烯釋放量之影響。The vase life of “Furore” and “Ornella” gerhera cut flowers treated with preservatives and exogenous ethylene at 0~10ppm concentrations were studied. Meanwhile, the water uptake, fresh weight change, respiration rate, and ethylene production of gerbera cut flower pulsed with preservative treatment were investigated. Ethylene all concentrations of tested increased the respiration rate and ethylene production of the treated flower, but not significantly affected their vase life. Pulse treatment with ethylene inhibitors, including aminotriazole (ATA) (1.2mM), 1 -methylcyclopropene (1-MCP) (1800ppb), retain (100ppm) and silver thiosulfate (STS) (0.1~2.0 mM), had no effect on prolong of the vase life of gerhera cut flower. The results showed that the cut flowers of gerbera were not sensitive to ethylene, and their senescence was not caused injury by ethylene. The vase life of these two cultivars prolonged for 4 days after pulse treatment with 1,3-dichloro-5, 5-dimethylhydantoin (DDMH), NiCl2 and sucrose for 2 hours. The best effect was obtained with the treatment of combination of 1.25 ppm DDMH, 250 ppm NiCl2 and 0.25% sucrose for “Furore” and treatment of combination of 25 ppm DDMH, 500 ppm NiCl2 and 0.5% sucrose for “Ornella”

一种降低滑坡涌浪对大坝危害的方法及装置

本发明公开了一种降低滑坡涌浪对大坝危害的方法及装置,本发明是在滑坡涌浪可能发生地1～2km处的水面上设置多道浮于水面的障碍物,通过浮于水面的障碍物削弱滑坡形成的涌浪水流势能；使滑坡涌浪的流速和高度降低至下游大坝可承受范围内,以确保滑坡涌浪不会对大坝造成危害。本发明的装置当滑坡涌浪过来时,涌浪从栅体通过,通过水流紊流掺混实现消能,降低滑坡涌浪速度和高度,通过多级悬栅后,可以将滑坡涌浪速度和高度降低为可接受的程度。这样到达大坝前的滑坡涌浪已经基本不对大坝造成危害。本发明具有消能效果好,投资较小,可以避免大规模的边坡治理和大坝加高或控制运行水位的发生,具有极大的经济效益
