Aiming at matching searching of customer demand in product configuration design of case - based reasoning, the conception of the entities, the entity, the attribute, the primary attribute set, the similar element etc. were introduced, and the similarity calculation model based on entity attribute was established ; the mapping relationship of customer demands and the product structure cellular feature during the process of product configuration was studied, and the calculation flow of similarity was put forward ; the type, range and weighting of attribute were analyzed, the calculation method of property similarity and formula of entity similarity were advanced
摘要針對基於實例推理的產品配置設計中客戶需求匹配搜索的問題，引入了實體集、實體、屬性、主屬性集、相似元等概念，建立了基於實體屬性的相似度計算模型；研究了產品配置過程中客戶需求與產品結構單元特徵之間的映射關系，提出了相似度的計算流程；分析了屬性的類型、值域和權重，提出了屬性相似度的計算方法和實體相似度的計算公式。 -
The effects of such elements as primary flow total pressure, flow rate, degree of fuel rich, nozzle structure, flying speed and secondary combustion on ejecting mode performance were researched. it was found that thrust augmentation can be achieved on the condition that the flying mach number is above 0. 7. to deeply analyze thrust augmentation mechanism in low speed range, the research was further continued by changing secondary combustion organization and aft - body configuration
研究了一次流總壓、流量、富燃程度、噴管結構、二次流來流速度、二次燃燒組織對引射模態性能的影響，發現實驗樣機構型在0 . 7ma以上的飛行條件下可以獲得推力增強，而在0 . 7ma以下無推力增強。 -
These measures are as follows : shorten the primary wind intervals to improve thermal load of the burner ; reduce the size of hypothetical circle of contact to prevent the flame from splashing ; use nozzles with larger height / width ratio to increase the effusive rigidity, so as to increase the jet flow depth of secondary wind into the main jet flow ; use a higher primary wind velocity to increase its jet flow rigidity ; use a special flame holder structure of the primary nozzle, so as to improve
這些技術措施主要有:縮小一次風間距以提高燃燒器區域熱負荷;縮小假想切圓防止火焰刷墻;採用高寬比較大的二次風噴口以增加射流剛性，提高二次風射流進入主射流的深度;採用較高的一次風速來提高一次風射流剛性;一次風噴口採用特殊穩燃結構;提高下二次風的托粉能力。 -
The paper s research indicates : with the high - speed development of the economy of guangdong, a large amount of surplus rural labor forces flow into two, three industries from primary industry, make the work structure of guangdong province improve constantly, and produce a greater work structure effect, the contribution to the economic growth of guangdong is more obvious, reach 1. 92 percentage points equally, contribute share and reach 2. 95 percentage points, is up to 13. 08 % to the contribution rate of the economic growth of guangdong equally in maximum, most greatly up to 22. 55 %
本文研究表明，隨著廣東經濟的高速發展，大量的農村剩餘勞動力從第一產業流向二、三產業，使廣東省的勞動結構不斷改善，並且產生一個比較大的勞動結構效應，對廣東經濟增長的貢獻比較明顯，平均達到1 . 92個百分點，最大值貢獻份額達到2 . 95個百分點，對廣東經濟增長的貢獻率平均達到13 . 08 ，最大達到22 . 55 。
