It didn t take much for him to see that she was absolute model material , and he encouraged her to enter the elite look of the year contest 其父母尊重女兒的心意,在ana十多歲時,便舉家移民到大城市rio de janeiro居住。
During the development , the cotton fiber cell only grows but does not divides , so it is a kind of model material for studying the mechanism of plant cell growth and development 近年來國內(nèi)外不少研究者已經(jīng)分離出一批對棉纖維初生生長發(fā)育有重要作用的功能基因,并闡明了這些基因的表達及調(diào)控特徵。
With the development of the rp / m , the key technology of rp / m focuses on how to make the mechanical machine parts , which results in the upsurge of the study on using metal materials as modeling materials 隨著rp / m技術(shù)的發(fā)展,要求突破原型零件制造的限制,制造具有實際功能的最終用途機械零件,因此,利用金屬作造型材料的rp / m技術(shù)的開發(fā)與研究引人注目。
In this paper , the metallic functional part is rapidly manufactured by laminated object manufacturing ( lom ) process using the thicker sheet metal as the modeling materials . but the question of modeling precision in the lom must be solved 本文提出以較厚的金屬板材作造型材料,采用分層實體制造方法快速制造金屬功能零件,但必須解決lom造型精度問題。
In this paper , based on the previous study on this project , a thought , which used 1mm thick metal sheet as modeling materials to fabricate the final function metal part according to the new lom process , is advanced . and also a question , the joining process of metal sheet , is indicated 在課題先期研究基礎(chǔ)上,本文提出以1mm厚金屬板材作為造型材料,用lom的方法制造金屬功能零件,并指出金屬分層板的連接技術(shù)仍是需迫切解決問題之一。
In accordance with the choice of model material in general principle , the dissertation obtains a set of model materials by 10 series of different mixture material mechanics test that simulate reliably the surrounding rock i , ii , iii in order to build physical model in cracked surrounding rocks 本文根據(jù)選擇模型材料的一般原則,通過10組不同配合比的合成材料力學性能試驗,得到了一組能可靠模擬、及類圍巖的模型材料以建立破碎圍巖的物理模型。
In the field of geophysics and information technology , it is important to express a mass of data that may be abstract or invisible directly and visually , with the aid of computer graphics and image process techniques . so visualization not only provides convenient model material for engineering design , but also is helpful to the following analysis . and it can make all information to be displayed directly , so the problems can be discovered and analyzed correctly 在地球物理與信息技術(shù)領(lǐng)域,將科學計算中產(chǎn)生的大量非直觀的、抽象的或者不可見的數(shù)據(jù),以圖形圖像的形式,直觀、形象地表達出來,除了可為工程設(shè)計提供方便好用的模型資料,而且可為下一步的數(shù)據(jù)解釋分析奠定基礎(chǔ),使工作者直觀地看到地質(zhì)現(xiàn)象的幾何形態(tài)、相互關(guān)系和分布,從而準確的發(fā)現(xiàn)問題、分析問題。
