Chung Ying Street: The Strange Story of a Town Divided Between Britain and China

為了解決Narrow down的問題，作者Chi-pang, Lau 這樣論述：

When colonial mandarins expanded the borders of Hong Kong in 1898, they cared little that the new frontier cut straight through the middle of a small market town - in fact, down the middle of its main street. For the next 99 years, British servicemen faced Chinese soldiers - and sometimes red guards

- across the narrow width of Chung Ying (China-Britain) Street. Through reminiscences and archive photos, many published for the first time, this book unveils the mysterious past of this unique border town. Dr Lau Chi-pang lives in Hong Kong, where he is professor of history at Lingnan University

提升發射機放大器線性度之主動射頻消除技術研究

為了解決Narrow down的問題，作者江光立 這樣論述：

論文為研究主動射頻消除技術提升發射機功率放大器(PA)線性度功能，其中發射機具有放大器非線性失真及射頻具有不完美因子包含頻率獨立與頻率相依IQ不平衡失真問題。為達成射頻端消除失真干擾信號，本論文提出一種共軛型的非線性廣義濾波器設計，搭配輔助發射路徑實現反相寬頻射頻信號可消除PA非線性與Image干擾信號。本論文研究步驟包含有設計一套仿真Parallel Hammerstein Model 來模擬PA非線性會遇到的問題與射頻不完美失真干擾及新型的廣義射頻消除濾波器之軟體模擬平台，並提出完整的時域估計PA非線性與 IQ不平衡參數，進而推導得共軛型非線性廣義濾波器係數，並可分析PA線性度性能。最後

，經由模擬之頻譜圖與星雲圖結果證實本論文所提出之共軛型的非線性廣義濾波器，可搭配輔助發射路徑實現反相寬頻與窄頻射頻信號消除PA非線性與Image干擾信號。

The Age of Clear Profit: Essays on Home and the Narrow Road

為了解決Narrow down的問題，作者 這樣論述：

At age fifty, when many hope to slow down, and what’s left, as the poet Kobayashi Issa once wrote, is ＂clear profit,＂ John Griswold was starting over---again---in a position he had worked decades to achieve. His family moved down the Mississippi Valley, expecting to create a good life with new fr

iends. What they found instead was a society ＂organized tightly by race, church attendance, and family name,＂ which in its corruption, laissez-faire corporatism, gun love, and environmental degradation foretold the heightened problems of the United States in an era of deepening political division. T

aking his cue from classical Asian poets such as Basho, Griswold begins to journey, to gain perspective, and to find his own narrow road. He travels around the rim of the Gulf of Mexico and to writers’ homes in Russia and New Mexico; attends the protests at Standing Rock; walks the Basho Trail in Ja

pan; and reports on the wholesale slaughter of a Texas rattlesnake roundup and the cruel weirdness of the Angola Prison Rodeo. Over eight years, Griswold bears witness, pays homage, and finds he is able to define and speak with gratitude about what is most important to him: his children, wholehearte

dness, and the act of trying. In the gap between complexity and a little peace and quiet, there is a way to profit anew.

LED光質和溫室披覆材料對萵苣生長之影響

為了解決Narrow down的問題，作者蔡竣宇 這樣論述：

萵苣（Lactuca sativa L.）屬菊科一年生草本植物，品種多，生長型態和特徵亦不同，葉色一般可分為深紅色、紅色和綠色三種。本研究首先探討紅光（R）、藍光（B）、綠光（G）和黃光（Y）四種不同光質LED（Light-emitting diode, LED），以120 µmole‧m-2‧s-1光強度及1000 ppm二氧化碳濃度，探討對綠葉波士頓萵苣（Boston lettuce）和紅葉紫艷萵苣（Ziyan Lettuces）兩種品種之生長和光合作用效率之影響。試驗15天後，兩種萵苣葉片外觀型態些微不同外，波斯頓萵苣生長量以綠光處理最高；紫艷萵苣生長量以紅光和綠光處理較高，藍光可促進

轉色。以20、40、60、80、100及120 µmole‧m-2‧s-1六種不同光強度與400、600、800、1000、1200及1400ppm 六種二氧化碳濃度下，於四種不同光質下之兩種萵苣的光合作用效率，波斯頓萵苣於光強度為100及120 µmole‧m-2‧s-1且二氧化碳濃度為1200及1400 ppm時，綠光有最高光合作用效率；紫艷萵苣於光強度120 µmole‧m-2‧s-1且二氧化碳濃度為1000ppm以上時，則以紅光有最高光合作用效率。三種光質不同比例混合之結果，波斯頓萵苣以紅藍綠混光RBG（R 32% + B 48 % + G 20 %）和紫艷萵苣以紅藍黃混光RBY（R

36% + B 54 % + Y 10 %）有最高的光合作用效率；植株生長量、葉片型態、硝酸鹽含量和電功率消耗，波斯頓萵苣於紅藍綠（RBG）混光處理，葉片型態較緊密，且呈色較深，雖生長量較綠光（G）和白光（W）低，但硝酸鹽含量且電功率消耗較低；紫艷萵苣於紅藍黃（RBY）混光，葉片呈色較深，生長量與紅光（R）比較並無顯著差異，但硝酸鹽含量且電功率消耗較低，兩種品種萵苣皆適用於消費者利用。以不同化學成分及配方比例，分別製成G4、G4+5%LDPE和G4+10%LDPE等三種披覆膜，結果於可見光波段透光率和拉伸強度以G4+5%LDPE較高，拉伸延展性和溫室降溫效果則以G4+10%LDPE較高，作物生

長量，波斯頓萵苣以G4披覆膜，紫艷萵苣以G4+5%LDPE最高，顯示兩種萵苣栽培適合之披覆膜並不相同。未來於植物工廠內可選用適宜的光照模式，以及適合化學材料所開發之披覆膜，改善溫室內適合作物生長之微氣候，以提高作物產量並讓消費者在食品安全上有更好的保障。
