rarely

The star in question , however , when some billions of years had passed since its birth , and its companions began to rarefy , was not satisfied with its destiny and became restless ? to such a point that its restlessness became visible even to those of us who are “ very ” distant and circumscribed by a “ very ” brief life 這顆我們持有疑問的安靜恒星? ?自誕生起經歷了無法計數的年月,它的同伴也已開始變得稀薄? ?也許并不滿意自己最后的命運,開始躁動起來,從而使渺小而遙遠的我們能夠看見它。

Based on the comprehensive analyses of the various solutions in rarefied gas dynamics and the fact in this research , the modeling and calculation for the flow in micro nozzle are carried out by using the direct simulation monte - carlo method , and the analysis of internal flow variations under some different working conditions are performed 在綜合考慮了稀薄氣體動力學問題各種解法和本課題實際研究的基礎上,本文采用直接模擬蒙特卡羅方法( dsmc )對微噴管內流場進行建模和計算,并分析了各種工況下的內流場變化。

With the rapid development of micro - satellite technology in china , micro nozzle being the key component of the micro - propulsion system has been paid much effort of research , in this realm , the simulation of rarefied flow in the micro nozzle is the key step for the design and performance improving of micro nozzle 隨著我國微小衛星研制的大力發展,作為微推進系統關鍵部件的微噴管研究成了重要的研究課題之一,對微噴管內流場稀薄氣流的模擬分析是微噴管設計和性能改善所需要解決的關鍵問題。

Still , to start on a brisk walk , and on such an errand as hers , on a dry clear wintry morning , through the rarefied air of these chalky hogs - backs , was not depressing ; and there is no doubt that her dream at starting was to win the heart of her mother - in - law , tell her whole history to that lady , enlist her on her side , and so gain back the truant 在一個干燥晴朗的冬季早晨,在白堊質山脊上清爽稀薄的空氣里,她邁著輕快的步伐趕路她去完成自己的這樣一項任務,心里并沒有感到氣餒。毫無疑問,她在動身時的夢想就是要討她婆婆的歡心,把自己的全部歷史告訴那位夫人,爭取她站到自己一邊來,這樣她就能把那位逃走了的人弄回來了。

In the previous direct simulation monte carlo ( dsmc ) method used in the dilute gas - solid flow , particle collision probability was calculated by the equation used for rarefied gas molecules . and gas phase was simulated by the laminar navier - stokes equations 已有的應用直接模擬蒙特卡羅( dsmc )方法模擬流化床內稀疏氣固兩相流動的研究中,均采用稀薄氣體分子碰撞概率的計算方法計算氣固兩相流中顆粒的碰撞概率,采用層流navier - stokes方程模擬氣相流動。

Technology does not only manifest itself in web and wires , but also in the rarefied area of financial engineering , with advanced mathematical models and complex equations developed to price new derivative products 科技不但應用于網絡及電纜通訊,更應用于金融工程設計,有關的專業人士不斷發展先進的數學模型及復雜的公式,以為新的衍生工具定價。

In this paper , we focus on some typical nozzles of micron dimension being developed for micro - propulsion system in and abroad , and make modeling and simulation analysis of the performance of rarefied flow in the micro nozzle 本文針對國外研制的微推進系統所用典型微米級噴管,對稀薄氣流在微噴管內的流動性能進行了建模和仿真分析。

Midway up the slope , however , i staggered to a halt , gasping in the rarefied air , well before i reached the heights where the equations of einstein and dirac would have made sense 登到山坡的一半時,我搖搖晃晃的停下來,呼吸稀薄的空氣,這時,距離我能夠理解愛因斯坦或狄拉克的方程式的高度還相差很遠。

Midway up the slope , however , i staggered to a halt , gasping in the rarefied air , well before i reached the heights where the equations of einstein and dirac would have made sense 可惜才到半山腰,便開始步履踉蹌;空氣稀薄,使我氣喘吁吁,不得不停下腳步,而愛因斯坦和狄拉克的方程式卻仍舊遠在高處。

Depending on excellent work , rarefied craftwork and peculiar form , the products always keep ahead in some industry 其產品以其制作精良,工藝考究,造型奇異,式樣繁多而居同行業領先。

The interactions concentrate on two regions : the compressed region in the front and the rarefied region in the wake 這種相互作用,集中在兩個區域內:即前部壓縮區和尾部稀化區。
