The little business plied by the good portress must have been progressing finely, for the cellarlike hole under the stairs was wet with emptied heeltaps and water
看樣子女門房經營的小生意一定很興隆，因為在這個地窖般的角落裡，樓梯腳下被洗酒杯的水倒得濕漉漉的。So, he pushed open the door with the weak rattle in its throat, stumbled down the two steps, got past the two ancient cashiers, and shouldered himself into the musty back closet where mr. lorry sat at great books ruled for figures, with perpendicular iron bars to his window as if that were ruled for figures too, and everything under the clouds were a sum
於是，他推開了門那門喉嚨里輕微地咕嚕了一聲，一個趔趄落下兩步階梯，走過了兩位老出納員，橫沖直撞地擠進了羅瑞先生那長了霉的后間密室。羅瑞先生坐在龐大的帳本面前，帳本的格子里寫滿了數字。他窗戶上垂直的鋼條似乎也是用來寫數字的格子，而在雲天之下的每一件事物則是填在格子里的數字。The analytical solutions of the gain, dispersion and population difference in the steady state of an open ladder lasing without inversion ( lwi ) system are at first given when the phase fluctuation of the driving field is considered. then the effects of the driving field phase fluctuation on the gain, dispersion and population difference are analyzed by the numerical results from the analytical solutions. our research shows that the phase fluctuation of the driving field will results in a finite line width ; with the line width increasing, the gain decreases monotonously, however, variation of the dispersion isn ? t monotonous, it has a maximum value when the line width takes some value ; the line width varying can ? t lead to change lasing from without to with population inversion
給出了有驅動場位相漲落的開放的梯型無粒子數反轉激光（ lwi ）系統增益、色散和布居數差的定態解析解，進而用得到的數值計算結果分析了驅動場位相漲落對增益、色散和布居數差的影響.研究結果表明，驅動場位相漲落將導致有限線寬;隨著線寬的增加，系統增益單調地減小，但系統色散的變化並不是單調的，當線寬取某個值時，色散有極大值;線寬的變化不能導致無反轉激光向反轉激光的轉變17. the review report has explained why the cwb cannot be replaced by traffic management measures such as electronic road pricing ; equal tolls for the cross harbour tunnels ; extension of the mtr to kennedy town ; provision of hillside escalators from central to mid - levels ; provision of bus - bus interchanges at the fringe areas of central and restricting loading and unloading times in central
17 .檢討報告書已解釋為何中環灣仔繞道不能以下述的交通管理措施取代，例如電子道路收費劃一過海隧道收費把地下鐵路伸延至堅尼地城興建中環至半山區的山坡自動扶梯在中環外圍設巴士轉車站和限制在中環上落客貨的時間。So if dca combines with classified methods, the ordination effect on samples and species is better than that of dcca and cca. 2. fso study on plant communities : we applly fuzzy set ordination ( fso ) to analyze the environmental factors and vegetation data
植物群落的模糊數學排序研究：運用模糊數學排序對樣地的環境因子和植被數據進行了直接梯度分析，結合twinspan分類結果，與dcca比較，模糊數學排序直觀的得出了環境因子和植物群落間的關系，解析度較高。分享友人
