data n. 1.資料,材料〔此詞系 datum 的復(fù)數(shù)。但 datum 罕用,一般即以 data 作為集合詞,在口語中往往用單數(shù)動詞;如系指一件資料,則說作 this data〕。 2.〔美國〕(觀察所得的)事實(shí),知識。 a data book 參考資料書。 gather data on ...收集…的資料[數(shù)據(jù)]。 The data is not enough to be convincing. 資料不足,尚難令人信服。
You re probably already seeing that these two listings contain the same data - in fact , they are semantically equivalent 您可能已經(jīng)看到,這兩個清單包含著同樣的數(shù)據(jù),事實(shí)上它們在語義上是等價的。
Nowadays , 99 % web site organize their information to web paper by html which is a semi structure format , and provides no semantic , and data organized by it can not be understand by computer , so computer can not analyze those data - in order to help people to find the information they want , some filter systems based on keywords appears . and those systems have became a indispensable part of the filter techniche . on the base of researching those systems , we provide a arithmetic based on qa 現(xiàn)在, 99的web站點(diǎn)的格式都是采用html這種半結(jié)構(gòu)化的數(shù)據(jù)格式來表示,而html標(biāo)記語言缺乏對語義的支持,無法讓計(jì)算機(jī)理解信息所蘊(yùn)涵的語義,從而也無法從這些數(shù)據(jù)中分析出隱含的信息。為了幫助用戶從基于html的文檔中查找有用信息,出現(xiàn)了很多基于關(guān)鍵詞的過濾系統(tǒng),另一方面,形成了面向互聯(lián)網(wǎng)的過濾技術(shù)中不可或缺的一部分。
First , based on the analysis to the development condition of computer and property of the input data of bridge , this paper , taking convenience and practicability as principle , develops the multi passages data - in system made up with human - computer interactive interface and excel import model . second , after comparing and analyzing to the calculation theories and methods of creep and shrinkage , clearing up the key steps of creep and shrinkage analysis , the paper takes incremental method to establish program to analyze secondary inner force caused by creep and shrinkage . third , the paper puts some optimal or simplified treatment to the contents of pre - stress and develops relative program ; in addition , through analysis to the different methods used to calculate the secondary inner force caused by pre - stress , the paper combines equivalent load method with finite element , carries out some simplified treatments , and establishes program to calculate secondary inner force caused by pre - stress 首先,在分析當(dāng)前計(jì)算機(jī)的發(fā)展?fàn)顩r及橋梁結(jié)構(gòu)輸入數(shù)據(jù)特點(diǎn)的基礎(chǔ)上,以方便、實(shí)用為原則,采用人機(jī)交互界面和excel輸入方式聯(lián)合的多通道數(shù)據(jù)輸入系統(tǒng);其次,通過比較分析徐變收縮計(jì)算的各種理論及方法,澄清了徐變收縮分析的關(guān)鍵過程,并采用增量法編制程序,實(shí)現(xiàn)徐變收縮次內(nèi)力分析;再次,對預(yù)應(yīng)力的相關(guān)計(jì)算內(nèi)容進(jìn)行適當(dāng)優(yōu)化或簡化處理,并編制相應(yīng)程序;另外,本文還在比較預(yù)應(yīng)力次內(nèi)力各種計(jì)算方法的基礎(chǔ)上,將等效荷載法結(jié)合有限元進(jìn)行一些簡化處理,編制程序?qū)崿F(xiàn)預(yù)應(yīng)力次內(nèi)力的計(jì)算;最后以三個算例來校核計(jì)算方法及程序運(yùn)行結(jié)果的可靠性,取得了預(yù)期效果。
