嵌套關系
英文
nest relation-
So we extent its function by adding sqlquery expressions which contain sql. it gets results from queries by jdbc api and convert it into xml format. then it uses xquery complier to query in succession in order to integrate related databases
Xquery語言本身並不能實現該功能，所以我們對它進行擴展，增加嵌套sql語句的sqlquery表達式，使用jdbc來查詢sql語句，而將產生的結果轉換為xml文檔，再使用xquery編譯器來實現查詢要求，達到集成關系數據庫的目的。Involuntarily, questions of these engineering datas " management appear, datas " persistance only depending relational model and rdbms is greatly insufficient, so this paper carefully studies object - relational mapping based on rdbms based on the analyse of home & overseas actualities, correlative theories and realizing methods of object - relational mapping, we find opl based on rdbms is the most suitable for object relatinoal mapping of clera. based on the engineering application analyse of opl in clera, function requirements, database modes, interface criterions and functions, running modes of opl have being detailedly described. with the framework of microsoft dna, a kind of realizing method of opl based on com / dcom / activex component technology has being brought forward, and this paper describes realizing keys from base tables " definition, object id and class hx class and inheritance of class, object storage, parallel control and affair, object query, object nesting, relations between objects, support of complex data types, right control of object and buffer management of object

本文中，介紹了時態數據庫的基本概念、發展、特點和分類；結合sidss的背景、特色及體系結構，詳細討論了sidss的時態性及其數學模型，指出將時態數據庫應用到sidss並作進一步的研究是必然趨勢，並在此基礎上研究了時態數據庫系統的模型；在探討了幾種模型之後，打破實體-關系類的模型的框框，提出了一個表達能力較強的嵌套時態數據模型，稱之為nter模型（ nestedtemporalentity - relationshipmodel ） ，並驗證將其應用到sidss系統中的表達能力；最後針對sidss的特點以及目前工資管理系統的狀況，進一步對基於時空關系的sidss系統、由時態驅動知識庫的sidss系統進行初步探討，以期今後對開發更完善的引） ss系統作進一步的研究。The results indicated that the dimension, shape and purity of base material could meet the functional demand of solid lubricant ; the thermal decomposition temperature of ptfe resin exceeds 400 c, but organic and inorganic packing filler added in ptfe made the water absorption rate of composite material increased, melting temperature and decomposition temperature decreased, in the meanwhile oxidative decomposition reaction was accompanied ; polar groups such as c = o, c - o - c and so on in the carbon fiber surface is advantageous to increase compatibility with other components and interlayer shearing strength ; uniform design experimental method could help to find the relationship between formula and frictional property by relatively small tests. the developing trend of each formula ' s friction coefficient could be showed by fitting curve ; the friction coefficient with no copper powder or graphite in formula was relatively big. this fact showed that copper powder and graphite should be used cooperatively ; it was found that when the ratio of copper powder to graphite by weight is 15 : 60, 30 : 30 - 40 and 60 : 15 - 30 respectively, the friction coefficient was relatively small. the degree of crystallinity of pure ptfe reached maximum by air cooling and the abrasion loss also reached maximum among three ones ; at the same time, the abrasion loss of solid lubricant sample was also the biggest among three ones ; when solid lubricant matched with 45 # steel axle or gcrl5 steel axle, lubricant transfer film could be formed on metal surface, thus direct contact between the surface of metal friction pair rings was reduced. their working life was elongated extremely ; there was mainly much graphite, a little ptff, moo3, feso4, cus and so on in lubricant transfer film
試驗結果表明：所選原料的尺寸、形狀及純度可滿足固體潤滑劑的性能要求；聚四氟乙烯樹脂熱分解溫度超過400 ，但在ptfe中加入無機填料會使復合材料吸水率提高，熔融溫度及分解溫度降低，且伴有氧化分解反應；碳纖維表面含有c = o及c - o - c等極性基團，有利於提高其與其它組分的相容性，提高層間剪切強度；均勻設計試驗方法能夠用較少的試驗次數找出配方與摩擦性能間的關系，擬合曲線基本能表示各配方的摩擦系數發展趨勢；配方中不加銅粉或不加石墨，其摩擦系數均較高，說明銅粉和石墨應該配合使用；當銅粉15份、石墨60份時，銅粉30份、石墨30 - 40份時，銅粉60 、石墨15 - 30份時，摩擦系數均具有較低值；純聚四氟乙烯樹脂在空氣冷卻時結晶度最大，磨損量也是三者中最大的；同時，固體潤滑劑試樣在空氣冷卻時的磨損量也是三者中最大的：不論是固體潤滑劑與45 #鋼軸配副或是固體潤滑劑鑲嵌入銅套后與gcr15鋼軸配副，在金屬表面均可形成潤滑轉移膜，從而減少金屬摩擦副表面間的直接接觸，大大延長其使用壽命;轉移膜中主要含有較多的石墨、少量聚四氟乙烯、 moo 。In the research task supported by the key technologies r & d program in the 9th five - year plan of jiangsu province, the study focuses on the nc milling programming software development method and the corresponding algorithms on the basis of acis. by using the development interfaces provided by acis, the author has made some innovation to tool path generation algorithms. based on acis, a new set operation method of loops is presented in this paper

Ninf （非第一範式）關系方法在處理非表格化的復雜結構對象時優于傳統關系方法，因而適合於時態關系的表達。嵌套關系數據庫能表示和處理時態信息，將其應用到工資智能決策支持系統中能方便地表達和處理信息，是本文所解決的問題。Select or clear the nested relation box
