On a level with the floor on every stairhead there was a low window which resembled a deep , square venthole , while in lanterns fastened to the walls flaring gas jets crudely illuminatcd the surrounding squalor and gave out a glowing heat which , as it mounted up the narrow stairwell , grew ever more intense 每道樓梯的平臺邊,貼近地面都有一扇低矮的窗戶,方方正正地凹進去,像是氣窗。一些懸掛在墻壁上的燈籠,發出煤氣光焰,強烈地照射著這種種貧寒景物,還散發出一股熱氣,向上升騰,并聚積在各層狹窄的螺旋形樓梯下。

The exhaust noise contains complex noise elements , including the exhaust noise with a base frequency measured in the number of exhausts in unit time , the resonance noise of the gas column in the pipe , the gas stream blowing noise at the exhaust manifold , the exhaust gas jetting and impact noise , the helmholtz resonance noise of the cylinder , the karman eddy noise and the turbulent noise inside the exhaust system 排氣噪聲包含了復雜的噪聲成分:以單位時間內排氣次數為基頻的排氣噪聲、管道內氣柱共振噪聲、排氣歧管處的氣流吹氣噪聲、廢氣噴注和沖擊噪聲、汽缸的亥姆霍茲共振噪聲、卡門渦流噪聲及排氣系統內部的湍流噪聲等。

An uneasy feeling of mingled fear and vague repugnance took possession of him . he looked up into the heights above him , where more battens , the gas jets on which were burning low , gleamed like galaxies of little bluish stars amid a chaos of iron rods , connecting lines of all sizes , hanging stages and canvases spread out in space , like huge cloths hung out to dry 他抬頭仰望舞臺上空,上面還有一些布景照明燈,燈頭都捻小了,宛如一群淡藍色的小星星在閃爍,上面的一切都顯得雜亂無章,布景格架粗細不一的電線吊梁升在上空的幕布亂糟糟地掛在舞臺上面,幕布像晾曬著的大床單。

Abstract : the paper introduces the brief cases of gas jet pump used for oil and gas well artificial lift , expounds operating mechanism , advantage and limitation of gas jet pump , analyses the actual results and service conditions of gas jet pump used for dewatering gas production wells . the analysis result shows the gas jet pump technology have the advantage of gas lift technology , and have higher efficiency and better result than semi - enclosed gas lift . service conditions of gas jet pump is the same with semi - enclosed gas lift . so it is worth using widely 文摘:介紹國內外氣體射流泵用于油氣井人工舉升的簡況,闡述其作用機理、優點及局限性,分析用于排水采氣井的實際效果、應用條件;認為氣體射流泵工藝是具有氣舉工藝的優點,又比半閉式氣舉效率更高、效果更好,應積極推廣的工藝,因其應用條件與半閉式氣舉相同,故在氣舉井上作為接替工藝尤為簡便可行。

The basic principle of copper matte converting process is briefly introduced in this paper . the basic characteristics , control targets and affecting factors are analysed . spontaneous heating process , temperature field in lining and gas jetting phenomenon are studied 本文簡要介紹了銅锍吹煉的基本原理,分析了銅锍吹煉的基本特性、吹煉過程的控制目標及其影響因素,對自熱過程、爐襯溫度場、氣體噴射現象進行了解析,對造渣制度的優化進行了研究。

The pavement was drying outside , and a cool wind blew along the gallery , swept the close hot air up beneath the glass that imprisoned it and shook the colored lanterns and the lines of gas jets and the giant fan which was flaring away like a set piece in an illumination 外邊的路面已經干了,沿著走廊吹來的一股涼風,驅散了玻璃天棚下的熱氣,把五顏六色的燈籠,一排排煤氣燈和像煙火一樣光輝奪目的巨型扇子吹得搖搖晃晃。

Firstly , the theories in laminar flow flame transmitting , gas jet current and flame stabilization are analyzed and the process of burning in burners and affected factors of flame stability is acquainted with , which can provide theoretical support to propose reconstructive plans 首先,分析層流火焰傳播、氣體射流以及火焰穩定性理論,了解燃燒器中燃燒過程和火焰穩定性的影響因素,為下面改造方案的提出提供理論支持。

It has been pointed out that for the application of cryogenic nitrogen gas jet in high speed milling of titanium alloy , unless the chipping and fracture caused by thermal cracks take place , the reduced temperature of cryogenic nitrogen gas will prolong the tool life 指出在低溫氮氣射流條件下高速銑削鈦合金時,只要熱裂紋的形成與擴展未引起刀具的崩刃及刀面的剝落,進一步降低低溫氮氣的溫度將提高刀具的使用壽命。

The experiments of high speed milling of titanium alloy were conducted under different cooling and lubricating modes , i . e . dry milling , flood coolant , oil mist with nitrogen gas , cryogenic nitrogen gas jet , and cryogenic nitrogen gas jet with minimal quantities of lubricant 在干銑削、澆注切削液、常溫氮氣油霧、低溫氮氣射流和低溫氮氣射流結合微量潤滑等冷卻潤滑條件下進行了鈦合金的高速銑削對比試驗。

Under the windows , white with reflected light , the pavement was violently illuminated . a perfect stream of brilliancy emanated from white globes , red lanterns , blue transparencies , lines of gas jets , gigantic watches and fans , outlined in flame and burning in the open 白色的球形燈罩紅色的燈籠藍色的透明畫一排排腳燈用燈管做成的巨大手表和扇子的模型發出一道道耀眼奪目的光芒,把玻璃櫥窗照得通明。

Many men did not enter the theater at once but stayed outside to talk while finishing their cigars under the rays of the line of gas jets , which shed a sallow pallor on their faces and silhouetted their short black shadows on the asphalt 許多人還沒有馬上進場,他們滯留在外面,一邊聊天,一邊抽雪茄。排燈的光線把他們的臉照得灰白,他們縮短了的身影在柏油馬路上清晰可見。

This lodge , situated between the actors staircase and that of the management , was shut in to right and left by large glass partitions and resembled a huge transparent lantern in which two gas jets were flaring 這個房間位于供演員上下的樓梯與通往經理室的樓梯之間,左右兩邊是兩大塊玻璃隔板,看上去頗像一只碩大的透明燈籠,里邊點著兩盞閃閃發光的煤氣燈。

As it vaporizes , tiny gas jets spin and tumble the ice shards across the surface of the water . during their brief lifetimes , the dry ice shards collide and spin a multi - armed vortex of white mist 乾冰氣化時產生的小噴流帶動乾冰碎片在水面不斷旋轉翻滾,互相碰撞,產生一團團有多個分支的白霧旋渦。

The experimental results indicate that cryogenic nitrogen gas jet with minimal quantities of lubricant is the most effective cooling and lubricating mode to reduce milling force and to retard tool wear 試驗結果表明,低溫氮氣射流結合微量潤滑能夠最有效地降低銑削力,抑制刀具磨損。

The use of cryogenic nitrogen gas jet to reduce the temperature of cutting zone and to avoid oxidation wear of tool in high speed milling titanium alloy was presented 為降低切削區溫度、防止刀具的氧化磨損,提出在低溫氮氣射流條件下進行鈦合金的高速銑削加工。

The rain had ceased , and there was now a deep silence in the room , which the fierce heat of the coke fire and the flare of the gas jets rendered still more oppressive 雨已停了,屋里一片沉靜,炭火和煤氣燈的火焰般的光芒散發出大量熱量,使屋里更加寂靜了。

They had extinguished the line of gas jets on the facade of the theater , and it was dark and very cool on the balcony , which seemed to them unoccupied 劇院正門上邊的一排煤氣燈剛剛熄滅了。陽臺上黑糊糊的,氣溫宜人,他們以為上面沒有人。

Prulliere had drawn near the hearth opposite the console table , where a coke fire was blazing and two more gas jets were flaring brightly 普律利埃爾走到桌子對面的壁爐旁邊,壁爐里燃著焦炭壁爐兩邊各有一盞煤氣燈,發出耀眼奪目的光芒。

A gas jet was flaring in the cupboard , within which it was possible to descry a tin - covered table and some shelves garnished with half - emptied bottles 壁柜里點著一盞煤氣燈,一張錫面桌子和幾塊擱板,擱板上面擺著已開了蓋子的酒瓶。
