用遞歸下降方法實現自底向上的語法分析We first present a number of desiderata for an xml - based query language, and based on this criterion, we introduce the syntax of a simple core ian - guage for semistructured data and then describe four extensions that have resulted in working prototypes. second, we present the algorithm for computing the result of a regular expression on data graph with cycles, the first - order interpretation of querying language for semistructured data, and explore structural recursion and bisimulation in semistructured data and propose an efficient and systematic way to computing a bisimulation between the two graphs. we also proposed and implemented a web querying system with database features
基於這些準則，對一個簡單的半結構數據查詢核心語言的語法提出了兩方面擴充；給出了計算數據圖中正規表達式的演算法；對半結構數據查詢語言的一階邏輯描述、結構遞歸和數據圖的雙態模擬（ bisimulation ）等問題進行了研究，提出了一種判定數據圖的bisimulation演算法；在xml數據查詢語言研究的基礎上，設計並實現了一種具有數據庫查詢特性的web查詢系統原型。The syntax analyzer has one recursive procedure for each nonterminal u.
對于每個非終結符號U，語法分析程序都有一個遞歸過程。The syntax analyzer has one recursive procedure for each nonterminal u
對于每個非終結符號u ，語法分析程序都有一個遞歸過程。In addition, some programming techniques, such as recursion, are impossible to use - - for example, this rules out protocol handlers being recursive - descent parsers
此外，象遞歸之類的一些編程的技術不可能使用例如，遞歸消解了協議處理程序成為循環下降的語法分析程序的可能。Then, using recursive arithmetic calculated reliability indices for directory tree, the method was realized by vb program ; the other is a method of reliability evaluation by interval arithmetic, which is the use of interval arithmetic to evaluate reliability, and the computation theory is also given. during the calculation, interval number replaced the component " s parameter and it takes into consideration the uncertainty of all of the parameters. in the study of power distribution system configuration, a new configuration model is set up which takes into account simultaneously the losses minimization and system reliability, then improved genetic arithmetic is described detail and of advantage for solving this problem
在配電網可靠性評估的研究中，提出了兩種實用的配電網可靠性評估方法：其一是利用網路分層和遞歸演算法理論，使用高級語言進行程序設計，提出了一種基於vb編程的配電網可靠性評估方法，該方法通過程序實現了網路拓撲結構的分層等效和可靠性指標的遞歸計算，使整個計算過程得到了簡化，並且界面窗口的可視化，使得評估過程便捷、形象；其二是提出了一種基於區間演算法的配電網可靠性評估方法，該方法是一種利用區間理論計算配電系統可靠性的不確定性評估方法；文章給出了區間運算的原理；討論了配電系統中區間數據的來源途徑，並用區間數代替元件的可靠性參數，對輻射形配電網進行了可靠性評估。Quantifiers can be used within the regular expressions of the spark tokenizer, and can be simulated by recursion in parse expression grammars
計量符可以在spark記號賦予器（ tokenizer ）的正則表達式中使用，並可以用解析表達式語法中的遞歸來進行模擬。The system realize the random binary three - dimensional recursive model, and generate three - dimensional tree model to compose natural scene ; in addition, it apply the accelerate algorithms based on the integrated polygon and texture, and realize interactive walkthrough in virtual environment
該系統用c + +語言實現了隨機二叉三維遞歸模型，生成三維樹木造型組成自然景物，並應用基於幾何和圖像的混合漫遊加速演算法，實現了虛擬環境的交互漫遊。( 2 ) in order to validate the efficiency of algorithm, this paper design and implement a testing, platform rule processor based on sql server. the main function of the processor is to translate the first order logic rule into embedded - sql programs, which make sql server dbms possess the capability in expressing recursive query with logic language
（ 2 ）為驗證演算法的有效性，該文設計實現了一個測試平臺? ?基於sqlserver的規則處理器，其主要功能為自動把一階邏輯規則轉換為含有sql語句的過程代碼，這使得sqlserver數據庫管理系統有了用邏輯數據語言表示遞歸查詢的能力。分享友人
