I have taken impotance to analyze the rallying point of famous product, concrete cost and capability of providing and guarantee in this artical, meanwhile, i have caculated the quantity of concrete needed for the year and got the regression equation with the historic data for drilling footage of eight years and the consuming quantity of oilwell cement by the method of linear regression, and it has very significance for the making of stock contract and the plan of concrete production, i have analyzed the physical distribution of oilwell cement by the transpotation flex and the advantage or disadvantage between direct distribution and distribution to store in this artical, and i have tried to find the balance point of the two distribution ways by the ecnomic analysis and pointd out the conception of economic semidiameter, and come to the conclusion of direct distribution, distribution to store, and subarea of distribution to store at last
本文對油井水泥供應商在品牌號召力、水泥成本、供應保障能力等方面進行了詳盡分析，並對供應商進行了能力排序;用線性回歸方法從八年鉆井進尺與油井水泥消耗量的歷史數據推算了當年度油井水泥需求量，得出了回歸方程，這對于油井水泥采購合同的制訂、水泥供應商生產計劃的制訂具有相當重要的意義;從運輸彈性分析出發對油井水泥物流配送進行了研究，對直達配送、入庫配送的優缺點進行了詳細的分析，在經濟分析的基礎上力求找到兩種配送方式的均衡點，並提出了經濟半徑的概念，得出了直達配送、入庫配送、入庫分區距離等幾項結論。Effects of different fuel - air ratios and different geometric parameters of dual - stage swirler ( such as inner diameters of the primary swirl and secondary swirl passages, outer diameters of the secondary swirl passages, vane angle of the primary and secondary swirler, the distance of the flare exit from throat etc ) on combustion performances are studied experimentally. the experimental results show that radial profiles of the outlet gas temperature 、 combustion efficiency 、 emissions of co2 、 co and nox and lean blowout are affected with different degrees by the different geometric parameters of dual - stage swirler and the arrangement of primary holes
在不同油氣比下，不同的雙級旋流器幾何參數（例如:一級與二級旋流器出口內徑d 、葉片安裝角、二級旋流器出口外徑d 、二級旋流器的喉道到出口截面的距離l和喉道前後的圓弧半徑r以及主燃孔孔布局等）對單頭部環形燃燒室的出口溫度分佈、燃燒效率、貧油熄火油氣比以及污染物（ co _ 2 、 co和nox ）排放等燃燒性能的影響規律進行了研究。
