Experimental studies were conducted at the yucheng comprehensive experimental station of the chinese academy of sciences during the period from march to june in 2003. respiration of a pulverous sandstone soil was studied under cultivation of winter wheat over a growth season. soil ch4 was measured by the static - chamber method combined with gas chromatography ( gc ) technique. the results indicated that the soil of winter wheat field in rapid growth season is a weak sink of ch4
本文利用靜態箱氣相色譜（ gc ）分析的方法，在中國科學院禹城綜合試驗站，對華北平原冬小麥生長旺季期間麥田土壤中ch _ 4氣體通量進行了測定，試驗起止時間為2003年3 6月，得出華北平原典型冬麥田土壤是大氣ch _ 4的弱吸收匯。 -
For the tectonic coal ， the properties of higher porosity and lower permeability make it capable of keeping higher gas pressure ； both of the “ isolating action ” and “ gas - cushion action ” cut down the resistance against outburst ； the specifity of high - defomed - extent makes desorption ， escape and flowing quickly become possible ； the existing of weak - seam or “ thoroughfare - seam ” create suitable conditions for the initial erupting and continued developing of coal and gas outburst. on the whole ， it is the synhesis action of all factors ， which leads to outbursts. the existing of tectonic coal with certain thickess is the essential condition of coal and gas outbursts ， but not the sufficient condition
高空隙率、低透氣性使構造煤能夠保持較高的瓦斯壓力；破碎性、 「隔離」作用及「氣墊」作用，使構造煤抵禦外力作用的能力大大降低；構造煤變形幅度大的特性，為瓦斯的迅速解吸、放散和快速流動創造了條件；構造煤薄弱分層或「通道層」的存在，則為煤與瓦斯突出的初始激發和持續發展奠定了基礎；上述因素的共同作用，影響和制約了煤與瓦斯突出的強度和分佈.盡管如此，一定厚度的構造煤的存在只是發生煤與瓦斯突出的必要條件和有利條件，而非充分條件 -
Having been engaged in technological consultation on inorganic chemical engineering, and make a speciality of purification of the gas from fluidized - bed roaster, and the treatment of the acid sludge and weak acid in the purification system of sulphuric acid
從事無機化工技術咨詢，擅長硫酸製造、制酸爐氣凈化技術以及凈化所產生酸泥和稀酸治理技術咨詢。 -
This kind of enterprise, in terms of its specialization, has strong tendency towards the " planning economy ", the competition inside the enterprise is very weak, the capability to withstand the danger is poor, and the level of technology is comparatively low. with the development of the project " western gas exported to the east ", the implementation of the city cleaning energy engineering during the " tenth - five - year plan " of china and the possible change after the entry of wto. the present equipment and technology cannot satisfy the needs of the society, in which the resource of natural gas is increasing fast, and cannot encounter the competition brought by the change of the country ' s policy
城市燃氣企業主要承擔城市燃氣、煤氣、液化石油氣的輸配和供應管理職能，屬于城市公用事業，這類企業由於其行業的特殊性，計劃經濟的色彩比較濃厚，企業核心競爭力不強，抵禦風險的能力比較弱，技術水平比較低，隨著國家"西氣東輸"工程的啟動和"十五"期間城市清潔能源工程的實施以及加入wto后政策面可能發生的變化，燃氣企業現有的裝備技術狀況已無法滿足社會日益增長的對天然氣資源供應的需求，無法對應國家政策變化而帶來的市場競爭，因此，燃氣企業通過技術創新和大規模的項目改造，增強企業競爭力和實力已成其為必然趨勢。 -
It is very important work for exploration to identify and evaluate oil layer, water layer, or gas layer from reservoir, and it is difficult for petroleum scientists to identify and evaluate light oil, whose color is weak, oiliness is light, volatility is strong, hydrocarbon saturation is low and fluorescence will disappear after a stretch
油氣水層的識別與評價是勘探工作的重要環節，其中輕質油層的識別與評價是油水層識別與評價的難點。輕質油在常溫常壓下含油顏色淺、油質輕、易揮發、含油級別較低、時間略長熒光普照顏色無，容易漏失，進而漏算儲量。 -
Directing against the problems of shortage of electric power during summer and winter seasons in the region of nanjing city, a scheme of heat, electricity and cool co - generation by using natural gas has been put forward, and techno - economic analysis for combined schemes of four kinds of different gas turbines with the refrigerating machine in a common residential quater being carried out, the suitability as well as strong and weak points of each scheme being expounded
摘要針對南京地區冬夏季用電緊張問題，提出住宅小區採用天然氣熱電冷三聯產的方案，並就某普通住宅小區4種不同燃氣輪機和製冷機組的組合方案進行技術經濟分析，闡明各方案的適用性和優缺點。 -
At the preliminary stage of burning the gas flows along the back surface of the submerged nozzle and no recirculation forms in the aft - end cavity. at the medium stage of burning a weak recirculation forms in the rear of aft - end cavity by the force of injection flow. at the end stage of burning the flow separates at the c ombustion channel and a strong vortex forms in the aft - end cavity
實驗結果表明，在發動機工作過程中隨著燃面的退移，燃燒室尾部的流動會發生很大變化，初始時刻背壁區加質流沿噴管背壁進入噴管，背壁區沒有迴流形成；中間時刻在加質流的驅動下背壁區後部形成較弱的迴流；結束時刻氣流在燃燒室壁面分離，背壁區形成強烈的迴流。 -
